terbutaline


Generic Name: terbutaline (oral) (ter BYOO ta leen)

Brand Names: Brethine, Bricanyl


What is terbutaline?

Terbutaline is a bronchodilator. Terbutaline works by relaxing muscles in the airways to improve breathing.


Terbutaline is used to treat bronchospasm (wheezing, shortness of breath) associated with lung diseases such as asthma, bronchitis, and emphysema.


Terbutaline may also be used for conditions other than those listed in this medication guide.


What is the most important information I should know about terbutaline?


Seek medical attention if you notice that you require more than your usual or more than the maximum amount of any asthma medication in a 24-hour period. An increased need for medication could be an early sign of a serious asthma attack.


What should I discuss with my healthcare provider before taking terbutaline?


Before taking terbutaline, tell your doctor if you have



  • heart disease or high blood pressure;




  • epilepsy or another seizure disorder;




  • diabetes;




  • an overactive thyroid (hyperthyroidism);



  • liver disease; or

  • kidney disease.

You may not be able to take terbutaline or you may require a dosage adjustment or special monitoring during treatment if you have any of the conditions listed above.


Terbutaline is in the FDA pregnancy category B. This means that terbutaline is not expected to be harmful to an unborn baby. Do not take terbutaline without first talking to your doctor if you are pregnant or could become pregnant during treatment. Terbutaline passes into breast milk and may affect a nursing baby. Do not take terbutaline without first talking to your doctor if you are breast-feeding a baby.

How should I take terbutaline?


Take terbutaline exactly as directed by your doctor. If you do not understand these directions, ask your pharmacist, nurse, or doctor to explain them to you.


Take each dose with a full glass of water.

It is important to take terbutaline regularly to get the most benefit.


Do not take terbutaline more often or in larger doses than is prescribed by your doctor. Taking more medication than is prescribed could be dangerous. Seek medical attention if you notice that you require more than your usual or more than the maximum amount of any asthma medication in a 24-hour period. An increased need for medication could be an early sign of a serious asthma attack.

Your doctor may want you to have lung function tests or other medical evaluations during treatment with terbutaline to monitor progress and side effects.


Store terbutaline at room temperature away from moisture and heat.

What happens if I miss a dose?


Take the missed dose as soon as you remember. However, if it is almost time for the next regularly scheduled dose, skip the missed dose and take the next one as directed. Do not take a double dose of this medication.


What happens if I overdose?


Seek emergency medical attention if an overdose is suspected.

Symptoms of a terbutaline overdose may include angina or chest pain, irregular heartbeats or a fluttering heart, seizures, tremor, weakness, headache, nausea, and vomiting.


What should I avoid while taking terbutaline?


Avoid situations that may worsen your respiratory condition such as exercising in cold, dry air; smoking; breathing in dust; and exposure to allergens such as pet fur.

Tricitrates Solution is used for:

Preventing certain types of kidney stones. It also may be used for other conditions as determined by your doctor.


Tricitrates Solution is a urinary alkalinizing agent. It neutralizes some of the acid in your urine, which reduces the formation of crystals in your urine that could become kidney stones.


Do NOT use Tricitrates Solution if:


  • you are allergic to any ingredient in Tricitrates Solution

  • you have high potassium levels in the blood, high aluminum levels in the blood, severe kidney problems, or you are unable to urinate

  • you have untreated Addison disease (an adrenal gland problem) or certain heart problems (heart failure or heart damage)

  • you are taking a product that contains aluminum (eg, antacids)

Contact your doctor or health care provider right away if any of these apply to you.



Before using Tricitrates Solution:


Some medical conditions may interact with Tricitrates Solution. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:

  • if you have stomach or bowel problems (eg, ulcer, diarrhea), a urinary tract infection, or you are dehydrated

  • if you have high blood acid levels; swelling of the hands, ankles, or feet; fluid buildup in the lungs; decreased urination; or trouble urinating

  • if you have preeclampsia (high blood pressure during pregnancy)

  • if you have low blood calcium levels, or you are on a sodium-restricted or potassium-restricted diet

  • if you have a condition in which your skin is breaking down (eg, severe burns)

Some MEDICINES MAY INTERACT with Tricitrates Solution. Tell your health care provider if you are taking any other medicines, especially any of the following:


  • Aldosterone blockers (eg, eplerenone), aliskiren, angiotensin-converting enzyme (ACE) inhibitors (eg, enalapril), potassium-sparing diuretics (eg, triamterene), or potassium supplements because the risk of high potassium levels, possibly with irregular heartbeat or a heart attack, may be increased

  • Products that contain aluminum (eg, antacids), digoxin, certain stimulants (eg, amphetamine), or sympathomimetics (eg, albuterol, pseudoephedrine) because the risk of their side effects may be increased by Tricitrates Solution

  • Lithium or tetracyclines (eg, doxycycline) because their effectiveness may be decreased by Tricitrates Solution

Uses For tropicamide


Tropicamide is used to dilate (enlarge) the pupil so that the doctor can see into the back of your eye. It is used before eye examinations, such as cycloplegic refraction and examination of the fundus of the eye. Tropicamide may also be used before and after eye surgery.


tropicamide is available only with your doctor's prescription.


Before Using tropicamide


In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For tropicamide, the following should be considered:


Allergies


Tell your doctor if you have ever had any unusual or allergic reaction to tropicamide or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.


Pediatric


Infants and young children and children with blond hair or blue eyes may be especially sensitive to the effects of tropicamide. This may increase the chance or severity of some of the side effects during treatment.


Geriatric


Elderly people are especially sensitive to the effects of tropicamide. This may increase the chance of side effects during treatment.


Pregnancy








Pregnancy CategoryExplanation
All TrimestersCAnimal studies have shown an adverse effect and there are no adequate studies in pregnant women OR no animal studies have been conducted and there are no adequate studies in pregnant women.

Breast Feeding


There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.


Interactions with Medicines


Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.


Interactions with Food/Tobacco/Alcohol


Certain medicines should not be used at or around the time of eating food or eating certain types of food since interactions may occur. Using alcohol or tobacco with certain medicines may also cause interactions to occur. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.


Other Medical Problems


The presence of other medical problems may affect the use of tropicamide. Make sure you tell your doctor if you have any other medical problems, especially:


  • Brain damage (in children) or

  • Down's syndrome (mongolism) (in children and adults) or

  • Glaucoma or

  • Spastic paralysis (in children)—Tropicamide may make the condition worse

Proper Use of tropicamide


To use:


  • First, wash your hands. Tilt the head back and, pressing your finger gently on the skin just beneath the lower eyelid, pull the lower eyelid away from the eye to make a space. Drop the medicine into this space. Let go of the eyelid and gently close the eyes. Do not blink. Keep the eyes closed and apply pressure to the inner corner of the eye with your finger for 2 or 3 minutes to allow the medicine to be absorbed by the eye. This is especially important in infants.

  • Immediately after using the eye drops, wash your hands to remove any medicine that may be on them. If you are using the eye drops for an infant or child, be sure to wash the infant's or child's hands also, and do not let any of the medicine get in the infant's or child's mouth.

  • To keep the medicine as germ-free as possible, do not touch the applicator tip to any surface (including the eye). Also, keep the container tightly closed.

Use tropicamide only as directed. Do not use more of it and do not use it more often than your doctor ordered. To do so may increase the chance of too much medicine being absorbed into the body and the chance of side effects.


Dosing


The dose of tropicamide will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of tropicamide. If your dose is different, do not change it unless your doctor tells you to do so.


The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.


  • For ophthalmic solution (eye drops) dosage form:
    • For cycloplegic refraction (eye examination):
      • Adults—One drop of 1% solution, repeated once in five minutes.

      • Children—One drop of 0.5 to 1% solution, repeated once in five minutes.


    • For examination of fundus of eye:
      • Adults and children—One drop of 0.5% solution fifteen to twenty minutes before examination.



Precautions While Using tropicamide


After tropicamide is applied to your eyes:


  • Your pupils will become unusually large and you will have blurring of vision, especially for close objects. Make sure your vision is clear before you drive, use machines, or do anything else that could be dangerous if you are not able to see well.

  • Your eyes will become more sensitive to light than they are normally. When you go out during the daylight hours, even on cloudy days, wear sunglasses that block ultraviolet (UV) light to protect your eyes from sunlight and other bright lights. Ordinary sunglasses may not protect your eyes. If you have any questions about the kind of sunglasses to wear, check with your doctor.

  • If these effects continue for longer than 24 hours after the medicine is used, check with your doctor.

tropicamide Side Effects


Along with its needed effects, a medicine may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.


Check with your doctor as soon as possible if any of the following side effects occur:


Symptoms of too much medicine being absorbed into the body
  • Clumsiness or unsteadiness

  • confusion

  • fast heartbeat

  • flushing or redness of face

  • hallucinations (seeing, hearing, or feeling things that are not there)

  • increased thirst or dryness of mouth

  • skin rash

  • slurred speech

  • swollen stomach in infants

  • unusual behavior, especially in children

  • unusual drowsiness, tiredness, or weakness

Some side effects may occur that usually do not need medical attention. These side effects may go away during treatment as your body adjusts to the medicine. Also, your health care professional may be able to tell you about ways to prevent or reduce some of these side effects. Check with your health care professional if any of the following side effects continue or are bothersome or if you have any questions about them:


More common
  • Blurred vision

  • headache

  • sensitivity of eyes to light

  • stinging of the eye when the medicine is applied

Other side effects not listed may also occur in some patients. If you notice any other effects, check with your healthcare professional.

Talwin Lactate


Generic Name: pentazocine (pen TAZ oh seen)

Brand Names: Talwin Lactate


What is Talwin Lactate (pentazocine)?

Pentazocine is narcotic pain medication


Pentazocine is used to treat moderate to severe pain. It is also used as part of anesthesia for surgery.


Pentazocine may also be used for other purposes not listed in this medication guide.


What is the most important information I should know about Talwin Lactate (pentazocine)?


Do not use this medication if you are allergic to pentazocine.

Before using pentazocine, tell your doctor if you have liver or kidney disease, a history of head injury or brain tumor, heart disease, high blood pressure, recent heart attack, asthma or other breathing disorders, mental illness, or a history of drug or alcohol addiction.


Pentazocine may be habit-forming and should be used only by the person it was prescribed for. Pentazocine should never be shared with another person, especially someone who has a history of drug abuse or addiction. Keep the medication in a secure place where others cannot get to it.

Use this medication exactly as it was prescribed for you. Never use pentazocine in larger amounts, or use it for longer than recommended by your doctor. Tell your doctor if the medicine seems to stop working as well in relieving your pain.


Do not stop using pentazocine suddenly, or you could have unpleasant withdrawal symptoms such as stomach pain, fever, runny nose, watery eyes, anxiety, or restless feeling. Talk to your doctor about how to avoid withdrawal symptoms when stopping the medication. Avoid drinking alcohol while using pentazocine. Alcohol may increase some of the side effects of pentazocine. Pentazocine can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.

What should I discuss with my health care provider before using Talwin Lactate (pentazocine)?


Do not use this medication if you are allergic to pentazocine. Pentazocine may be habit-forming and should be used only by the person it was prescribed for. Pentazocine should never be shared with another person, especially someone who has a history of drug abuse or addiction. Keep the medication in a secure place where others cannot get to it.

If you have certain conditions, you may need a dose adjustment or special tests to safely use this medication. Before using pentazocine, tell your doctor if you have


  • liver or kidney disease;


  • a history of head injury or brain tumor;




  • epilepsy or other seizure disorder;




  • heart disease, high blood pressure, recent heart attack;




  • asthma, COPD, sleep apnea, or other breathing disorders;




  • a dependence on narcotic pain medications;




  • mental illness; or




  • a history of drug or alcohol addiction.




Pentazocine may be harmful to an unborn baby. It could also cause addiction or withdrawal symptoms in a newborn if the mother uses pentazocine during pregnancy. Before you use this medication, tell your doctor if you are pregnant.

Pentazocine is sometimes used during early labor, but using it just before childbirth can cause breathing problems in a newborn.


Pentazocine may pass into breast milk and could harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.

Older adults may be more sensitive to the effects of this medication.


How is pentazocine given?


Use this medication exactly as it was prescribed for you. Never use pentazocine in larger amounts, or use it for longer than recommended by your doctor. Follow the directions on your prescription label. Tell your doctor if the medicine seems to stop working as well in relieving your pain.


Pentazocine is given as an injection under the skin, into a muscle, or into a vein. Your doctor, nurse, or other healthcare provider will give you this injection. You may be shown how to inject your medicine at home. Do not self-inject this medicine if you do not fully understand how to give the injection and properly dispose of used needles and syringes.


Do not mix pentazocine with other medicines in the same syringe or IV line.


Use each disposable needle only one time. Throw away used needles in a puncture-proof container (ask your pharmacist where you can get one and how to dispose of it). Keep this container out of the reach of children and pets.


If you are giving pentazocine as an injection under the skin, use a different place on your body each time you give yourself an injection. Your care provider will show you the places on your body where you can safely inject the medication. Do not inject into the same place two times in a row. Pentazocine can cause damage to the skin and underlying tissues or muscles if it is injected multiple times into the same skin area.


Do not stop using pentazocine suddenly, or you could have unpleasant withdrawal symptoms such as stomach pain, fever, runny nose, watery eyes, anxiety, or restless feeling. Talk to your doctor about how to avoid withdrawal symptoms when stopping the medication. Store pentazocine at room temperature away from moisture and heat.

What happens if I miss a dose?


Since pentazocine is often used as needed, you may not be on a dosing schedule. If you are using the medication regularly, use the missed dose as soon as you remember. If it is almost time for the next dose, skip the missed dose and wait until your next regularly scheduled dose. Do not use extra medicine to make up the missed dose.


What happens if I overdose?


Seek emergency medical attention if you think you have used too much of this medicine.

Symptoms of a pentazocine overdose are not known.


What should I avoid while using Talwin Lactate (pentazocine)?


Avoid drinking alcohol while using pentazocine. Alcohol may increase some of the side effects of pentazocine. Pentazocine can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.

Tell your doctor if you regularly use other medicines that make you sleepy (such as cold or allergy medicine, sleeping pills, muscle relaxers, and medicine for seizures, depression, or anxiety). They can add to sleepiness caused by pentazocine.

Triesence



triamcinolone acetonide

Dosage Form: injection
FULL PRESCRIBING INFORMATION

Indications and Usage for Triesence



Ophthalmic Diseases


Triesence® (triamcinolone acetonide injectable suspension) 40 mg/mL is indicated for:


• sympathetic ophthalmia,


• temporal arteritis,


• uveitis, and


• ocular inflammatory conditions unresponsive to topical corticosteroids.



Visualization during Vitrectomy


Triesence® suspension is indicated for visualization during vitrectomy.



Triesence Dosage and Administration



Dosage for Treatment of Ophthalmic Diseases


The initial recommended dose of Triesence® suspension is 4 mg (100 microliters of 40 mg/mL suspension) with subsequent dosage as needed over the course of treatment.



Dosage for Visualization during Vitrectomy


The recommended dose of Triesence® suspension is 1 to 4 mg (25 to 100 microliters of 40 mg/mL suspension) administered intravitreally.



Preparation for Administration


STRICT ASEPTIC TECHNIQUE IS MANDATORY. The vial should be vigorously shaken for 10 seconds before use to ensure a uniform suspension. Prior to withdrawal, the suspension should be inspected for clumping or granular appearance (agglomeration). An agglomerated product results from exposure to freezing temperatures and should not be used. After withdrawal, Triesence® suspension should be injected without delay to prevent settling in the syringe. Careful technique should be employed to avoid the possibility of entering a blood vessel or introducing organisms that can cause infection.



Administration


The injection procedure should be carried out under controlled aseptic conditions, which include the use of sterile gloves, a sterile drape, and a sterile eyelid speculum (or equivalent). Adequate anesthesia and a broad-spectrum microbicide should be given prior to the injection. Following the injection, patients should be monitored for elevation in intraocular pressure and for endophthalmitis. Monitoring may consist of a check for perfusion of the optic nerve head immediately after the injection, tonometry within 30 minutes following the injection, and biomicroscopy between two and seven days following the injection. Patients should be instructed to report any symptoms suggestive of endophthalmitis without delay.


Each vial should only be used for the treatment of a single eye. If the contralateral eye requires treatment, a new vial should be used and the sterile field, syringe, gloves, drapes, eyelid speculum, and injection needles should be changed before Triesence® suspension is administered to the other eye.



Dosage Forms and Strengths


Single use 1 mL vial containing 40 mg/mL of sterile triamcinolone acetonide suspension.



Contraindications


Corticosteroids are contraindicated in patients with systemic fungal infections.


Triamcinolone is contraindicated in patients who are hypersensitive to corticosteroids or any components of this product. Rare instances of anaphylactoid reactions have occurred in patients receiving corticosteroid therapy. [See Adverse Reactions (6)].



Warnings and Precautions



Ophthalmic Effects


Triesence® suspension should not be administered intravenously. Strict aseptic technique is mandatory.


Risk of infection


Corticosteroids may mask some signs of infection, and new infections may appear during their use. There may be decreased resistance and inability to localize infection when corticosteroids are used. Corticosteroids may enhance the establishment of secondary ocular infections due to fungi or viruses. If an infection occurs during corticosteroid therapy, it should be promptly controlled by suitable antimicrobial therapy.


See also Increased Risks Related to Infection (5.3).


Elevated Intraocular Pressure


Increases in intraocular pressure associated with triamcinolone acetonide injection have been observed in 20-60% of patients. This may lead to glaucoma with possible damage to the optic nerve. Effects on intraocular pressure may last up to 6 months following injection and are usually managed by topical glaucoma therapy. A small percentage of patients may require aggressive non-topical treatment. Intraocular pressure as well as perfusion of the optic nerve head should be monitored and managed appropriately.


Endophthalmitis


The rate of infectious culture positive endophthalmitis is 0.5%. Proper aseptic techniques should always be used when administering triamcinolone acetonide. In addition, patients should be monitored following the injection to permit early treatment should an infection occur.


Cataracts


Use of corticosteroids may produce cataracts, particularly posterior subcapsular cataracts.


Patients with Ocular Herpes Simplex


Corticosteroids should be used cautiously in patients with ocular herpes simplex because of possible corneal perforation. Corticosteroids should not be used in active ocular herpes simplex.



Alterations in Endocrine Function


Hypothalamic-pituitary-adrenal (HPA) axis suppression, Cushing's syndrome, and hyperglycemia. Monitor patients for these conditions with chronic use.


Corticosteroids can produce reversible HPA axis suppression with the potential for glucocorticosteroid insufficiency after withdrawal of treatment. Drug induced secondary adrenocortical insufficiency may be minimized by gradual reduction of dosage. This type of relative insufficiency may persist for months after discontinuation of therapy; therefore, in any situation of stress occurring during that period, hormone therapy should be reinstituted.


Metabolic clearance of corticosteroids is decreased in hypothyroid patients and increased in hyperthyroid patients. Changes in thyroid status of the patient may necessitate adjustment in dosage.



Increased Risks Related to Infections


Corticosteroids may increase the risks related to infections with any pathogen, including viral, bacterial, fungal, protozoan, or helminthic infections. The degree to which the dose, route and duration of corticosteroid administration correlates with the specific risks of infection is not well characterized; however, with increasing doses of corticosteroids, the rate of occurrence of infectious complications increases.


Corticosteroids may mask some signs of infection and may reduce resistance to new infections.


Corticosteroids may exacerbate infections and increase risk of disseminated infection. The use of corticosteroids in active tuberculosis should be restricted to those cases of fulminating or disseminated tuberculosis in which the corticosteroid is used for the management of the disease in conjunction with an appropriate antituberculous regimen.


Chickenpox and measles can have a more serious or even fatal course in non-immune children or adults on corticosteroids. In children or adults who have not had these diseases, particular care should be taken to avoid exposure. If a patient is exposed to chickenpox, prophylaxis with varicella zoster immune globulin (VZIG) may be indicated. If patient is exposed to measles, prophylaxis with pooled intramuscular immunoglobulin (IG) may be indicated. If chickenpox develops, treatment with antiviral agents may be considered.


Corticosteroids should be used with great care in patients with known or suspected Strongyloides (threadworm) infestation. In such patients, corticosteroid-induced immunosuppression may lead to Strongyloides hyperinfection and dissemination with widespread larval migration, often accompanied by severe enterocolitis and potentially fatal gram-negative septicemia.


Corticosteroids may increase risk of reactivation or exacerbation of latent infection. If corticosteroids are indicated in patients with latent tuberculosis or tuberculin reactivity, close observation is necessary as reactivation of the disease may occur. During prolonged corticosteroid therapy, these patients should receive chemoprophylaxis.


Corticosteroids may activate latent amebiasis. Therefore, it is recommended that latent or active amebiasis be ruled out before initiating corticosteroid therapy in any patient who has spent time in the tropics or in any patient with unexplained diarrhea.


Corticosteroids should not be used in cerebral malaria.



Alterations in Cardiovascular/Renal Function


Corticosteroids can cause elevation of blood pressure, salt and water retention, and increased excretion of potassium and calcium. These effects are less likely to occur with the synthetic derivatives except when used in large doses. Dietary salt restriction and potassium supplementation may be necessary. These agents should be used with caution in patients with hypertension, congestive heart failure, or renal insufficiency.


Literature reports suggest an association between use of corticosteroids and left ventricular free wall rupture after a recent myocardial infarction; therefore, therapy with corticosteroids should be used with caution in these patients.



Use in Patients with Gastrointestinal Disorders


There is an increased risk of gastrointestinal perforation in patients with certain GI disorders. Signs of GI perforation, such as peritoneal irritation, may be masked in patients receiving corticosteroids.


Corticosteroids should be used with caution if there is a probability of impending perforation, abscess or other pyogenic infections; diverticulitis; fresh intestinal anastomoses; and active or latent peptic ulcer.



Behavioral and Mood Disturbances


Corticosteroid use may be associated with central nervous system effects ranging from euphoria, insomnia, mood swings, personality changes, and severe depression, to frank psychotic manifestations. Also, existing emotional instability or psychotic tendencies may be aggravated by corticosteroids.



Decrease in Bone Density


Corticosteroids decrease bone formation and increase bone resorption both through their effect on calcium regulation (i.e., decreasing absorption and increasing excretion) and inhibition of osteoblast function. This, together with a decrease in the protein matrix of the bone secondary to an increase in protein catabolism, and reduced sex hormone production, may lead to inhibition of bone growth in children and adolescents and the development of osteoporosis at any age. Special consideration should be given to patients at increased risk of osteoporosis (i.e., postmenopausal women) before initiating corticosteroid therapy and bone density should be monitored in patients on long term corticosteroid therapy.



Vaccination


Administration of live or live attenuated vaccines is contraindicated in patients receiving immunosuppressive doses of corticosteroids. Killed or inactivated vaccines may be administered; however, the response to such vaccines cannot be predicted. Immunization procedures may be undertaken in patients who are receiving corticosteroids as replacement therapy, e.g., for Addison's disease.


While on corticosteroid therapy, patients should not be vaccinated against smallpox. Other immunization procedures should not be undertaken in patients who are on corticosteroids, especially on high dose, because of possible hazards of neurological complications and a lack of antibody response.



Effect on Growth and Development


Long-term use of corticosteroids can have negative effects on growth and development in children. Growth and development of pediatric patients on prolonged corticosteroid therapy should be carefully monitored.



Use in Pregnancy


Triamcinolone acetonide can cause fetal harm when administered to a pregnant woman. Human and animal studies suggest that use of corticosteroids during the first trimester of pregnancy is associated with an increased risk of orofacial clefts, intrauterine growth restriction and decreased birth weight. If this drug is used during pregnancy, or if the patient becomes pregnant while using this drug, the patient should be apprised of the potential hazard to the fetus. [See Use inSpecific Populations (8.1)].



Weight Gain


Systemically administered corticosteroids may increase appetite and cause weight gain.



Neuromuscular Effects


Although controlled clinical trials have shown corticosteroids to be effective in speeding the resolution of acute exacerbations of multiple sclerosis, they do not show that they affect the ultimate outcome or natural history of the disease. The studies do show that relatively high doses of corticosteroids are necessary to demonstrate a significant effect.


An acute myopathy has been observed with the use of high doses of corticosteroids, most often occurring in patients with disorders of neuromuscular transmission (e.g., myasthenia gravis), or in patients receiving concomitant therapy with neuromuscular blocking drugs (e.g., pancuronium). This acute myopathy is generalized, may involve ocular and respiratory muscles, and may result in quadriparesis. Elevation of creatine kinase may occur. Clinical improvement or recovery after stopping corticosteroids may require weeks to years.



Kaposi's Sarcoma


Kaposi's sarcoma has been reported to occur in patients receiving corticosteroid therapy, most often for chronic conditions. Discontinuation of corticosteroids may result in clinical improvement.



Adverse Reactions


Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.


Adverse event data were collected from 300 published articles containing data from controlled and uncontrolled clinical trials which evaluated over 14,000 eyes treated with different concentrations of triamcinolone acetonide. The most common dose administered within these trials was triamcinolone acetonide 4 mg administered as primary or adjunctive therapy primarily as a single injection.


The most common reported adverse events following administration of triamcinolone acetonide were elevated intraocular pressure and cataract progression. These events have been reported to occur in 20-60% of patients.


Less common reactions occurring in up to 2% include endophthalmitis (infectious and non-infectious), hypopyon, injection site reactions (described as blurring and transient discomfort), glaucoma, vitreous floaters, and detachment of retinal pigment epithelium, optic disc vascular disorder, eye inflammation, conjunctival hemorrhage and visual acuity reduced. Cases of exophthalmos have also been reported.


Common adverse reactions for systemically administered corticosteroids include fluid retention, alteration in glucose tolerance, elevation in blood pressure, behavioral and mood changes, increased appetite and weight gain.


Other reactions reported to have occurred with the administration of corticosteroids include:


Allergic Reactions: Anaphylactoid reaction, anaphylaxis, angioedema


Cardiovascular: Bradycardia, cardiac arrest, cardiac arrhythmias, cardiac enlargement, circulatory collapse, congestive heart failure, fat embolism, hypertrophic cardiomyopathy in premature infants, myocardial rupture following recent myocardial infarction, pulmonary edema, syncope, tachycardia, thromboembolism, thrombophlebitis, vasculitis


Dermatologic: Acne, allergic dermatitis, cutaneous and subcutaneous atrophy, dry scalp, edema, facial erythema, hyper or hypopigmentation, impaired wound healing, increased sweating, petechiae and ecchymoses, rash, sterile abscess, striae, suppressed reactions to skin tests, thin fragile skin, thinning scalp hair, urticaria


Endocrine: Abnormal fat deposits, decreased carbohydrate tolerance, development of Cushingoid state, hirsutism, manifestations of latent diabetes mellitus and increased requirements for insulin or oral hypoglycemic agents in diabetics, menstrual irregularities, moon facies, secondary adrenocortical and pituitary unresponsiveness (particularly in times of stress, as in trauma, surgery or illness), suppression of growth in children


Fluid and Electrolyte Disturbances: Potassium loss, hypokalemic alkalosis, sodium retention


Gastrointestinal: Abdominal distention, elevation in serum liver enzymes levels (usually reversible upon discontinuation), hepatomegaly, hiccups, malaise, nausea, pancreatitis, peptic ulcer with possible perforation and hemorrhage, ulcerative esophagitis


Metabolic: Negative nitrogen balance due to protein catabolism


Musculoskeletal: Aseptic necrosis of femoral and humeral heads, charcot-like arthropathy, loss of muscle mass, muscle weakness, osteoporosis, pathologic fracture of long bones, steroid myopathy, tendon rupture, vertebral compression fractures


Neurological: Arachnoiditis, convulsions, depression, emotional instability, euphoria, headache, increased intracranial pressure with papilledema (pseudo-tumor cerebri) usually following discontinuation of treatment, insomnia, meningitis, neuritis, neuropathy, paraparesis/paraplegia, paresthesia, sensory disturbances, vertigo


Reproductive: Alteration in motility and number of spermatozoa.



Drug Interactions


• Amphotericin B: There have been cases reported in which concomitant use of Amphotericin B and hydrocortisone was followed by cardiac enlargement and congestive heart failure. See Potassium depleting agents.


• Anticholinesterase agents: Concomitant use of anticholinesterase agents and corticosteroids may produce severe weakness in patients with myasthenia gravis. If possible, anticholinesterase agents should be withdrawn at least 24 hours before initiating corticosteroid therapy.


• Anticoagulant agents: Co-administration of corticosteroids and warfarin usually results in inhibition of response to warfarin, although there have been some conflicting reports. Therefore, coagulation indices should be monitored frequently to maintain the desired anticoagulant effect.


• Antidiabetic agents: Because corticosteroids may increase blood glucose concentrations, dosage adjustments of antidiabetic agents may be required.


• Antitubercular drugs: Serum concentrations of isoniazid may be decreased.


• CYP 3A4 inducers (e.g., barbiturates, phenytoin, carbamazepine, and rifampin): Drugs such as barbiturates, phenytoin, ephedrine, and rifampin, which induce hepatic microsomal drug metabolizing enzyme activity may enhance metabolism of corticosteroid and require that the dosage of corticosteroid be increased.


• CYP 3A4 inhibitors (e.g., ketoconazole, macrolide antibiotics): Ketoconazole has been reported to decrease the metabolism of certain corticosteroids by up to 60% leading to an increased risk of corticosteroid side effects.


• Cholestyramine: Cholestyramine may increase the clearance of corticosteroids.


• Cyclosporine: Increased activity of both cyclosporine and corticosteroids may occur when the two are used concurrently. Convulsions have been reported with concurrent use.


• Digitalis: Patients on digitalis glycosides may be at increased risk of arrhythmias due to hypokalemia.


• Estrogens, including oral contraceptives: Estrogens may decrease the hepatic metabolism of certain corticosteroids thereby increasing their effect.


• NSAIDS including aspirin and salicylates: Concomitant use of aspirin or other non-steroidal antiinflammatory agents and corticosteroids increases the risk of gastrointestinal side effects. Aspirin should be used cautiously in conjunction with corticosteroids in hypoprothrombinemia. The clearance of salicylates may be increased with concurrent use of corticosteroids.


• Potassium depleting agents (e.g., diuretics, Amphotericin B): When corticosteroids are administered concomitantly with potassium-depleting agents, patients should be observed closely for development of hypokalemia.


• Skin tests: Corticosteroids may suppress reactions to skin tests.


• Toxoids and live or inactivated vaccines: Due to inhibition of antibody response, patients on prolonged corticosteroid therapy may exhibit a diminished response to toxoids and live or inactivated vaccines. Corticosteroids may also potentiate the replication of some organisms contained in live attenuated vaccines.



USE IN SPECIFIC POPULATIONS



Pregnancy


Teratogenic Effects: Pregnancy Category D


[See Warnings and Precautions (5.10)]


Multiple cohort and case controlled studies in humans suggest that maternal corticosteroid use during the first trimester increases the rate of cleft lip with or without cleft palate from about 1/1000 infants to 3- 5/1000 infants. Two prospective case control studies showed decreased birth weight in infants exposed to maternal corticosteroids in utero.


Triamcinolone acetonide was teratogenic in rats, rabbits, and monkeys. In rats and rabbits, triamcinolone acetonide was teratogenic at inhalation doses of 0.02 mg/kg and above and in monkeys, triamcinolone acetonide was teratogenic at an inhalation dose of 0.5 mg/kg (1/4 and 7 times the recommended human dose). Dose-related teratogenic effects in rats and rabbits included cleft palate and/or internal hydrocephaly and axial skeletal defects, whereas the effects observed in monkeys were cranial malformations. These effects are similar to those noted with other corticosteroids.


Corticosteroids should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Infants born to mothers who received corticosteroids during pregnancy should be carefully observed for signs of hypoadrenalism.



Nursing Mothers


Corticosteroids are secreted in human milk. Reports suggest that steroid concentrations in human milk are 5 to 25% of maternal serum levels, and that total infant daily doses are small, less than 0.2% of the maternal daily dose. The risk of infant exposure to steroids through breast milk should be weighed against the known benefits of breastfeeding for both the mother and baby.



Pediatric Use


The efficacy and safety of corticosteroids in the pediatric population are based on the well established course of effect of corticosteroids which is similar in pediatric and adult populations.


The adverse effects of corticosteroids in pediatric patients are similar to those in adults. [See Adverse Reactions (6)].


Like adults, pediatric patients should be carefully observed with frequent measurements of blood pressure, weight, height, intraocular pressure, and clinical evaluation for the presence of infection, psychosocial disturbances, thromboembolism, peptic ulcers, cataracts, and osteoporosis. Children, who are treated with corticosteroids by any route, including systemically administered corticosteroids, may experience a decrease in their growth velocity. This negative impact of corticosteroids on growth has been observed at low systemic doses and in the absence of laboratory evidence of HPA axis suppression (i.e., cosyntropin stimulation and basal cortisol plasma levels). Growth velocity may therefore be a more sensitive indicator of systemic corticosteroid exposure in children than some commonly used tests of HPA axis function. The linear growth of children treated with corticosteroids by any route should be monitored, and the potential growth effects of prolonged treatment should be weighed against clinical benefits obtained and the availability of other treatment alternatives. In order to minimize the potential growth effects of corticosteroids, children should be titrated to the lowest effective dose.



Geriatric Use


No overall differences in safety or effectiveness were observed between elderly subjects and younger subjects, and other reported clinical experience with triamcinolone has not identified differences in responses between the elderly and younger patients. However, the incidence of corticosteroid-induced side effects may be increased in geriatric patients and are dose-related. Osteoporosis is the most frequently encountered complication, which occurs at a higher incidence rate in corticosteroid-treated geriatric patients as compared to younger populations and in age-matched controls. Losses of bone mineral density appear to be greatest early on in the course of treatment and may recover over time after steroid withdrawal or use of lower doses.



Triesence Description


Triesence® (triamcinolone acetonide injectable suspension) 40 mg/mL is a synthetic corticosteroid with anti-inflammatory action. Each mL of the sterile, aqueous suspension provides 40 mg of triamcinolone acetonide, with sodium chloride for isotonicity, 0.5% (w/v) carboxymethylcellulose sodium and 0.015% polysorbate 80. It also contains potassium chloride, calcium chloride (dihydrate), magnesium chloride (hexahydrate), sodium acetate (trihydrate), sodium citrate (dihydrate) and water for injection. Sodium hydroxide and hydrochloric acid may be present to adjust pH to a target value 6 - 7.5.


The chemical name for triamcinolone acetonide is 9-Fluro- 11β, 16α, 17,21-tetrahydroxypregna-1,4-diene-3,20-dione cyclic 16,17- acetal with acetone. Its structural formula of C24H31FO6 is:



434.50 MW


Triamcinolone acetonide occurs as a white to cream-colored, crystalline powder having not more than a slight odor and is practically insoluble in water and very soluble in alcohol.



Triesence - Clinical Pharmacology



Mechanism of Action


Naturally occurring glucocorticoids (hydrocortisone and cortisone), which also have salt-retaining properties, are used as replacement therapy in adrenocortical deficiency states. Their synthetic analogs such as prednisolone and triamcinolone are primarily used for their anti-inflammatory effects in disorders of many organ systems.


Triamcinolone acetonide possesses glucocorticoid activity typical of this class of drug, but with little or no mineralocorticoid activity. For the purposes of comparison, the following is the equivalent milligram dosage of the various glucocorticoids:











Cortisone, 25Prednisone, 5Paramethasone, 2
Hydrocortisone, 20Methylprednisolone, 4Betamethasone, 0.75
Prednisolone, 5Triamcinolone, 4Dexamethasone, 0.75

Corticosteroids have been demonstrated to depress the production of eosinophils and lymphocytes, but erythropoiesis and production of polymorphonuclear leukocytes are stimulated. Inflammatory processes (edema, fibrin deposition, capillary dilatation, migration of leukocytes and phagocytosis) and the later stages of wound healing (capillary proliferation, deposition of collagen, cicatrization) are inhibited.



Pharmacokinetics


Aqueous humor pharmacokinetics of triamcinolone have been assessed in 5 patients following a single intravitreal administration (4 mg) of triamcinolone acetonide. Aqueous humor samples were obtained from 5 patients (5 eyes) via an anterior chamber paracentesis on Days 1, 3, 10, 17 and 31 post injection. Peak aqueous humor concentrations of triamcinolone ranged from 2151 to 7202 ng/mL, half-life 76 to 635 hours, and the area under the concentration-time curve (AUC0-t) from 231 to 1911 ng.h/mL following the single intravitreal administration. The mean elimination half-life was 18.7 ± 5.7 days in 4 nonvitrectomized eyes (4 patients). In a patient who had undergone vitrectomy (1 eye), the elimination half-life of triamcinolone from the vitreous was much faster (3.2 days) relative to patients that had not undergone vitrectomy.



Nonclinical Toxicology



Carcinogenesis, Mutagenesis, Impairment of Fertility


No evidence of mutagenicity was detected from in-vitro tests conducted with triamcinolone acetonide including a reverse mutation test in Salmonella bacteria and a forward mutation test in Chinese hamster ovary cells. With regard to carcinogenicity, in a two-year study in rats, triamcinolone acetonide caused no treatment-related carcinogenicity at oral doses up to 0.001mg/kg and in a two-year study in mice, triamcinolone acetonide caused no treatment-related carcinogenicity at oral doses up to 0.003 mg/kg (less than 1/25th of the recommended human dose). In male and female rats, triamcinolone acetonide caused no change in pregnancy rate at oral doses up to 0.015 mg/kg, but caused increased fetal resorptions and stillbirths and decreases in pup weight and survival at doses of 0.005 mg/kg (less than 1/10th of the recommended human dose).



Animal Toxicology and/or Pharmacology


Studies were conducted with triamcinolone acetonide, including those employing the proposed dosage form, i.e., 4.0% triamcinolone acetonide injectable suspension formulation containing 0.5% carboxymethylcellulose and 0.015% polysorbate-80 in a balanced salt solution.


Triamcinolone acetonide was demonstrated to be non-inflammatory when injected intravitreally in NZW rabbits, non-cytotoxic to mouse L-929 cells in an in-vitro assay and non-sensitizing in a guinea-pig maximization assay. Furthermore, the results of single-dose intravitreal injection studies with triamcinolone acetonide in both rabbits and monkeys demonstrate that the drug is well tolerated for up to one month with only minor findings of slight decrease in body weight gain and slight corneal thinning.

Patient Counseling Information


Patients should discuss with their physician if they have had recent or ongoing infections or if they have recently received a vaccine.


There are a number of medicines that can interact with corticosteroids such as triamcinolone. Patients should inform their health-care provider of all the medicines they are taking, including over-thecounter and prescription medicines (such as phenytoin, diuretics, digitalis or digoxin, rifampin, amphotericin B, cyclosporine, insulin or diabetes medicines, ketoconazole, estrogens including birth control pills and hormone replacement therapy, blood thinners such as warfarin, aspirin or other NSAIDS, barbiturates), dietary supplements, and herbal products. If patients are taking any of these drugs, alternate therapy, dosage adjustment, and/or special test may be needed during the treatment.


Patients should be advised of common adverse reactions that could occur with corticosteroid use to include elevated intraocular pressure, cataracts, fluid retention, alteration in glucose tolerance, elevation in blood pressure, behavioral and mood changes, increased appetite and weight gain.
