Trental




Generic Name: pentoxifylline

Dosage Form: tablet, film coated
Trental®

(pentoxifylline)

Tablets, 400 mg

Trental Description


Trental® (pentoxifylline) tablets for oral administration contain 400 mg of the active drug and the following inactive ingredients: FD&C Red No. 3, hypromellose USP, magnesium stearate NF, polyethylene glycol NF, povidone USP, talc USP, titanium dioxide USP, and hydroxyethyl cellulose USP in an extended-release formulation. Trental is a tri-substituted xanthine derivative designated chemically as 1-(5-oxohexyl)-3,7-dimethylxanthine that, unlike theophylline, is a hemorrheologic agent, i.e. an agent that affects blood viscosity. Pentoxifylline is soluble in water and ethanol, and sparingly soluble in toluene. The CAS Registry Number is 6493-05-6.


The chemical structure is:




Trental - Clinical Pharmacology



Mode of Action


Pentoxifylline and its metabolites improve the flow properties of blood by decreasing its viscosity. In patients with chronic peripheral arterial disease, this increases blood flow to the affected microcirculation and enhances tissue oxygenation. The precise mode of action of pentoxifylline and the sequence of events leading to clinical improvement are still to be defined. Pentoxifylline administration has been shown to produce dose-related hemorrheologic effects, lowering blood viscosity, and improving erythrocyte flexibility. Leukocyte properties of hemorrheologic importance have been modified in animal and in vitro human studies. Pentoxifylline has been shown to increase leukocyte deformability and to inhibit neutrophil adhesion and activation. Tissue oxygen levels have been shown to be significantly increased by therapeutic doses of pentoxifylline in patients with peripheral arterial disease.



Pharmacokinetics and Metabolism


After oral administration in aqueous solution pentoxifylline is almost completely absorbed. It undergoes a first-pass effect and the various metabolites appear in plasma very soon after dosing. Peak plasma levels of the parent compound and its metabolites are reached within 1 hour. The major metabolites are Metabolite l (1-[5-hydroxyhexyl]-3,7-dimethylxanthine) and Metabolite V (1-[3-carboxypropyl]-3,7-dimethylxanthine), and plasma levels of these metabolites are 5 and 8 times greater, respectively, than pentoxifylline.


Following oral administration of aqueous solutions containing 100 to 400 mg of pentoxifylline, the pharmacokinetics of the parent compound and Metabolite l are dose-related and not proportional (non-linear), with half-life and area under the blood-level time curve (AUC) increasing with dose. The elimination kinetics of Metabolite V are not dose-dependent. The apparent plasma half-life of pentoxifylline varies from 0.4 to 0.8 hours and the apparent plasma half-lives of its metabolites vary from 1 to 1.6 hours. There is no evidence of accumulation or enzyme induction (Cytochrome P450) following multiple oral doses.


Excretion is almost totally urinary; the main biotransformation product is Metabolite V. Essentially no parent drug is found in the urine. Despite large variations in plasma levels of parent compound and its metabolites, the urinary recovery of Metabolite V is consistent and shows dose proportionality. Less than 4% of the administered dose is recovered in feces. Food intake shortly before dosing delays absorption of an immediate-release dosage form but does not affect total absorption. The pharmacokinetics and metabolism of Trental have not been studied in patients with renal and/or hepatic dysfunction. The pentoxifylline AUC was increased and elimination rate decreased in an older population (60–68 years, n=6) compared to younger individuals (22–30 years, n=6) (see PRECAUTIONS, Geriatric Use).


After administration of the 400 mg extended-release Trental tablet, plasma levels of the parent compound and its metabolites reach their maximum within 2 to 4 hours and remain constant over an extended period of time. Coadministration of Trental tablets with meals resulted in an increase in mean Cmax and AUC by about 28% and 13% for pentoxifylline, respectively. Cmax for Metabolite 1 also increased by about 20%. The extended release of pentoxifylline from the tablet eliminates peaks and troughs in plasma levels for improved gastrointestinal tolerance.



Indications and Usage for Trental


Trental is indicated for the treatment of patients with intermittent claudication on the basis of chronic occlusive arterial disease of the limbs. Trental can improve function and symptoms but is not intended to replace more definitive therapy, such as surgical bypass, or removal of arterial obstructions when treating peripheral vascular disease.



Contraindications


Trental should not be used in patients with recent cerebral and/or retinal hemorrhage or in patients who have previously exhibited intolerance to this product or methylxanthines such as caffeine, theophylline, and theobromine.



Precautions



General


Patients with chronic occlusive arterial disease of the limbs frequently show other manifestations of arteriosclerotic disease. Trental has been used safely for treatment of peripheral arterial disease in patients with concurrent coronary artery and cerebrovascular diseases, but there have been occasional reports of angina, hypotension, and arrhythmia. Controlled trials do not show that Trental causes such adverse effects more often than placebo, but, as it is a methylxanthine derivative, it is possible some individuals will experience such responses. Patients on Warfarin should have more frequent monitoring of prothrombin times, while patients with other risk factors complicated by hemorrhage (e.g., recent surgery, peptic ulceration, cerebral and/or retinal bleeding) should have periodic examinations for bleeding including, hematocrit and/or hemoglobin.



Drug Interactions


Although a causal relationship has not been established, there have been reports of bleeding and/or prolonged prothrombin time in patients treated with Trental with and without anticoagulants or platelet aggregation inhibitors. Patients on Warfarin should have more frequent monitoring of prothrombin times, while patients with other risk factors complicated by hemorrhage (e.g., recent surgery, peptic ulceration) should have periodic examinations for bleeding including hematocrit and/or hemoglobin. Concomitant administration of Trental and theophylline-containing drugs leads to increased theophylline levels and theophylline toxicity in some individuals. Such patients should be closely monitored for signs of toxicity and have their theophylline dosage adjusted as necessary. Trental has been used concurrently with antihypertensive drugs, beta blockers, digitalis, diuretics, antidiabetic agents, and antiarrhythmics, without observed problems. Small decreases in blood pressure have been observed in some patients treated with Trental; periodic systemic blood pressure monitoring is recommended for patients receiving concomitant antihypertensive therapy. If indicated, dosage of the antihypertensive agents should be reduced.



Carcinogenesis, Mutagenesis and Impairment of Fertility


Long-term studies of the carcinogenic potential of pentoxifylline were conducted in mice and rats by dietary administration of the drug at doses up to 450 mg/kg (approximately 19 times the maximum recommended human daily dose (MRHD) in both species when based on body weight; 1.5 times the MRHD in the mouse and 3.3 times the MRHD in the rat when based on body surface area). In mice, the drug was administered for 18 months, whereas in rats, the drug was administered for 18 months followed by an additional 6 months without drug exposure. In the rat study, there was a statistically significant increase in benign mammary fibroadenomas in females of the 450 mg/kg group. The relevance of this finding to human use is uncertain. Pentoxifylline was devoid of mutagenic activity in various strains of Salmonella (Ames test) and in cultured mammalian cells (unscheduled DNA synthesis test) when tested in the presence and absence of metabolic activation. It was also negative in the in vivo mouse micronucleus test.



Pregnancy


Category C. Teratogenicity studies have been performed in rats and rabbits using oral doses up to 576 and 264 mg/kg, respectively. On a weight basis, these doses are 24 and 11 times the maximum recommended human daily dose (MRHD); on a body-surface-area basis, they are 4.2 and 3.5 times the MRHD. No evidence of fetal malformation was observed. Increased resorption was seen in rats of the 576 mg/kg group. There are no adequate and well controlled studies in pregnant women. Trental (pentoxifylline) should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.



Nursing Mothers


Pentoxifylline and its metabolites are excreted in human milk. Because of the potential for tumorigenicity shown for pentoxifylline in rats, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.



Pediatric Use


Safety and effectiveness in pediatric patients have not been established.



Geriatric Use


Clinical studies of Trental did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.


The active metabolite is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.



Adverse Reactions


Clinical trials were conducted using either extended-release Trental tablets for up to 60 weeks or immediate-release Trental capsules for up to 24 weeks. Dosage ranges in the tablet studies were 400 mg bid to tid and in the capsule studies, 200–400 mg tid. The table summarizes the incidence (in percent) of adverse reactions considered drug related, as well as the numbers of patients who received extended-release Trental tablets, immediate-release Trental capsules, or the corresponding placebos. The incidence of adverse reactions was higher in the capsule studies (where dose related increases were seen in digestive and nervous system side effects) than in the tablet studies. Studies with the capsule include domestic experience, whereas studies with the extended-release tablets were conducted outside the U.S.


The table indicates that in the tablet studies few patients discontinued because of adverse effects.

Trental has been marketed in Europe and elsewhere since 1972. In addition to the above symptoms, the following have been reported spontaneously since marketing or occurred in other clinical trials with an incidence of less than 1%; the causal relationship was uncertain:


    

Cardiovascular - dyspnea, edema, hypotension.

    

Digestive - anorexia, cholecystitis, constipation, dry mouth/thirst.

    

Nervous - anxiety, confusion, depression, seizures, aseptic meningitis.

    

Respiratory - epistaxis, flu-like symptoms, laryngitis, nasal congestion.

    

Skin and Appendages - brittle fingernails, pruritus, rash, urticaria, angioedema.

    

Special Senses - blurred vision, conjunctivitis, earache, scotoma.

    

Miscellaneous - bad taste, excessive salivation, leukopenia, malaise, sore throat/swollen neck glands, weight change.

A few rare events have been reported spontaneously worldwide since marketing in 1972. Although they occurred under circumstances in which a causal relationship with pentoxifylline could not be established, they are listed to serve as information for physicians. Cardiovascular — angina, arrhythmia, tachycardia, anaphylactoid reactions. Digestive — hepatitis, jaundice, increased liver enzymes; and Hemic and Lymphatic — decreased serum fibrinogen, pancytopenia, aplastic anemia, leukemia, purpura, thrombocytopenia.



Overdosage


Overdosage with Trental has been reported in pediatric patients and adults. Symptoms appear to be dose related. A report from a poison control center on 44 patients taking overdoses of enteric-coated pentoxifylline tablets noted that symptoms usually occurred 4–5 hours after ingestion and lasted about 12 hours. The highest amount ingested was 80 mg/kg; flushing, hypotension, convulsions, somnolence, loss of consciousness, fever, and agitation occurred. All patients recovered. In addition to symptomatic treatment and gastric lavage, special attention must be given to supporting respiration, maintaining systemic blood pressure, and controlling convulsions. Activated charcoal has been used to absorb pentoxifylline in patients who have overdosed.



Trental Dosage and Administration


The usual dosage of Trental in extended-release tablet form is one tablet (400 mg) three times a day with meals.


While the effect of Trental may be seen within 2 to 4 weeks, it is recommended that treatment be continued for at least 8 weeks. Efficacy has been demonstrated in double-blind clinical studies of 6 months duration.


Digestive and central nervous system side effects are dose related. If patients develop these effects it is recommended that the dosage be lowered to one tablet twice a day (800 mg/day). If side effects persist at this lower dosage, the administration of Trental should be discontinued.



How is Trental Supplied


Trental (pentoxifylline) is available for oral administration as 400-mg pink film-coated oblong tablets imprinted Trental; supplied in bottles of 100 (NDC 0039-0078-10).

treprostinil injection


Generic Name: treprostinil injection (tre PROS ti nil)

Brand Names: Remodulin


What is treprostinil injection?

Treprostinil dilates (or widens) the arteries and decreases the amount of blood clotting platelets in your body. These effects lower blood pressure in the pulmonary artery that leads from the heart to the lungs.


Treprostinil is used to treat pulmonary arterial hypertension (PAH). It improves your ability to exercise and prevents your condition from getting worse.


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


What is the most important information I should know about treprostinil injection?


Before using this medication, tell your doctor if you have low blood pressure, liver disease, or a bleeding or blood clotting disorder.


Treprostinil is given as an continuous (around-the-clock) injection using an infusion pump. The medicine enters the body through a catheter placed under your skin or into a vein. Your doctor, nurse, or pharmacist will give you specific instructions on how to use an infusion pump and inject your medicine.


Your doctor may want you to be in a hospital when you start using treprostinil. This is so you can be watched for any signs of serious side effects from the medicine.


You will probably have to use this medicine for several months or years to control your condition and keep it from getting worse.

Use treprostinil regularly to get the most benefit. Get your prescription refilled before you run out of medicine completely. Make sure you have a backup infusion pump and infusion sets available so as not to interrupt your treatment if one infusion pump stops working.

Treprostinil injection Dosing Information


Usual Adult Dose for Pulmonary Hypertension:

Infusion:
Initial dose: 1.25 nanogram/kg per minute by continuous infusion. The subcutaneous route is preferred but the drug may be administered by a central intravenous line if the subcutaneous route is not tolerated. The rate may be decreased to 0.625 nanogram/kg/minute if the initial dose is not tolerated by the patient.
Maintenance dose: The infusion rate may be increased in increments of no more than 1.25 nanogram/kg/minute per week for the first 4 weeks, and thereafter by no more than 2.5 nanograms/kg/minute per week. Dosage adjustments should be titrated to a dose where PAH symptoms are improved and adverse effects are minimized (headache, nausea, emesis, restlessness, anxiety, and infusion site pain or reaction). Although doses of up to 100 nanograms/kg/minute have been reported, there is little experience with doses greater than 40 nanograms/kg/minute.

Inhalation:
Use only with the Tyvaso Inhalation System. Administer undiluted, as supplied. A single breath of Tyvaso delivers approximately 6 mcg of treprostinil
Initial dosage: 3 breaths [18 mcg] per treatment session. If 3 breaths are not tolerated, reduce to 1 or 2 breaths. Administer in 4 separate treatment sessions each day approximately four hours apart, during waking hours.
Maintenance dose: Dosage should be increased by an additional 3 breaths at approximately 1-2 week intervals, if tolerated. Titrate to target maintenance dosage of 9 breaths or 54 mcg per treatment session as tolerated.

Usual Pediatric Dose for Pulmonary Hypertension:

Inhalation:
Less than 16 years: Safety and efficacy have not been established.
16 to 18 years:
Initial dose: 1.25 nanogram/kg per minute by continuous infusion. The subcutaneous route is preferred but the drug may be administered by a central intravenous line if the subcutaneous route is not tolerated. The rate may be decreased to 0.625 nanogram/kg/minute if the initial dose is not tolerated by the patient.
Maintenance dose: The infusion rate may be increased in increments of no more than 1.25 nanogram/kg/minute per week for the first 4 weeks, and thereafter by no more than 2.5 nanograms/kg/minute per week. Dosage adjustments should be titrated to a dose where PAH symptoms are improved and adverse effects are minimized (headache, nausea, emesis, restlessness, anxiety, and infusion site pain or reaction). There is little experience with doses greater than 40 nanograms/kg/minute.


What other drugs will affect treprostinil injection?

The subcutaneous route is preferred but the drug may be administered by a central intravenous line if the subcutaneous route is not tolerated. The rate may be decreased to 0.625 nanogram/kg/minute if the initial dose is not tolerated by the patient.
Maintenance dose: The infusion rate may be increased in increments of no more than 1.25 nanogram/kg/minute per week for the first 4 weeks, and thereafter by no more than 2.5 nanograms/kg/minute per week. Dosage adjustments should be titrated to a dose where PAH symptoms are improved and adverse effects are minimized (headache, nausea, emesis, restlessness, anxiety, and infusion site pain or reaction). Although doses of up to 100 nanograms/kg/minute have been reported, there is little experience with doses greater than 40 nanograms/kg/minute.

Inhalation:
Use only with the Tyvaso Inhalation System. Administer undiluted, as supplied. A single breath of Tyvaso delivers approximately 6 mcg of treprostinil
Initial dosage: 3 breaths [18 mcg] per treatment session. If 3 breaths are not tolerated, reduce to 1 or 2 breaths. Administer in 4 separate treatment sessions each day approximately four hours apart, during waking hours.
Maintenance dose: Dosage should be increased by an additional 3 breaths at approximately 1-2 week intervals, if tolerated. Titrate to target maintenance dosage of 9 breaths or 54 mcg per treatment session as tolerated.

Usual Pediatric Dose for Pulmonary Hypertension:

Inhalation:
Less than 16 years: Safety and efficacy have not been established.
16 to 18 years:
Initial dose: 1.25 nanogram/kg per minute by continuous infusion. The subcutaneous route is preferred but the drug may be administered by a central intravenous line if the subcutaneous route is not tolerated. The rate may be decreased to 0.625 nanogram/kg/minute if the initial dose is not tolerated by the patient.
Maintenance dose: The infusion rate may be increased in increments of no more than 1.25 nanogram/kg/minute per week for the first 4 weeks, and thereafter by no more than 2.5 nanograms/kg/minute per week. Dosage adjustments should be titrated to a dose where PAH symptoms are improved and adverse effects are minimized (headache, nausea, emesis, restlessness, anxiety, and infusion site pain or reaction). There is little experience with doses greater than 40 nanograms/kg/minute.

aprotinin bovine

Dosage Form: injection


Trasylol® administration may cause fatal anaphylactic or anaphylactoid reactions. Fatal reactions have occurred with an initial (test) dose as well as with any of the components of the dose regimen. Fatal reactions have also occurred in situations where the initial (test) dose was tolerated. The risk for anaphylactic or anaphylactoid reactions is increased among patients with prior aprotinin exposure and a history of any prior aprotinin exposure must be sought prior to Trasylol® administration. The risk for a fatal reaction appears to be greater upon re-exposure within 12 months of the most recent prior aprotinin exposure. Trasylol® should be administered only in operative settings where cardiopulmonary bypass can be rapidly initiated. The benefit of Trasylol® to patients undergoing primary CABG surgery should be weighed against the risk of anaphylaxis associated with any subsequent exposure to aprotinin. (See CONTRAINDICATIONS, WARNINGS and PRECAUTIONS.)




Trasylol Description


Trasylol® (aprotinin injection), C284H432N84O79S7, is a natural proteinase inhibitor obtained from bovine lung. Aprotinin (molecular weight of 6512 daltons), consists of 58 amino acid residues that are arranged in a single polypeptide chain, cross-linked by three disulfide bridges. It is supplied as a clear, colorless, sterile isotonic solution for intravenous administration. Each milliliter contains 10,000 KIU (Kallikrein Inhibitor Units) (1.4 mg/mL) and 9 mg sodium chloride in water for injection. Hydrochloric acid and/or sodium hydroxide is used to adjust the pH to 4.5-6.5.



Trasylol - Clinical Pharmacology



Mechanism of Action:


Aprotinin is a broad spectrum protease inhibitor which modulates the systemic inflammatory response (SIR) associated with cardiopulmonary bypass (CPB) surgery. SIR results in the interrelated activation of the hemostatic, fibrinolytic, cellular and humoral inflammatory systems. Aprotinin, through its inhibition of multiple mediators [e.g., kallikrein, plasmin] results in the attenuation of inflammatory responses, fibrinolysis, and thrombin generation.


Aprotinin inhibits pro-inflammatory cytokine release and maintains glycoprotein homeostasis. In platelets, aprotinin reduces glycoprotein loss (e.g., GpIb, GpIIb/IIIa), while in granulocytes it prevents the expression of pro-inflammatory adhesive glycoproteins (e.g., CD11b).


The effects of aprotinin use in CPB involves a reduction in inflammatory response which translates into a decreased need for allogeneic blood transfusions, reduced bleeding, and decreased mediastinal re-exploration for bleeding.



Pharmacokinetics:


The studies comparing the pharmacokinetics of aprotinin in healthy volunteers, cardiac patients undergoing surgery with cardiopulmonary bypass, and women undergoing hysterectomy suggest linear pharmacokinetics over the dose range of 50,000 KIU to 2 million KIU. After intravenous (IV) injection, rapid distribution of aprotinin occurs into the total extracellular space, leading to a rapid initial decrease in plasma aprotinin concentration. Following this distribution phase, a plasma half-life of about 150 minutes is observed. At later time points, (i.e., beyond 5 hours after dosing) there is a terminal elimination phase with a half-life of about 10 hours.


Average steady state intraoperative plasma concentrations were 137 KIU/mL (n=10) after administration of the following dosage regimen: 1 million KIU IV loading dose, 1 million KIU into the pump prime volume, 250,000 KIU per hour of operation as continuous intravenous infusion (Regimen B). Average steady state intraoperative plasma concentrations were 250 KIU/mL in patients (n=20) treated with aprotinin during cardiac surgery by administration of Regimen A (exactly double Regimen B): 2 million KIU IV loading dose, 2 million KIU into the pump prime volume, 500,000 KIU per hour of operation as continuous intravenous infusion.


Following a single IV dose of radiolabelled aprotinin, approximately 25-40% of the radioactivity is excreted in the urine over 48 hours. After a 30 minute infusion of 1 million KIU, about 2% is excreted as unchanged drug. After a larger dose of 2 million KIU infused over 30 minutes, urinary excretion of unchanged aprotinin accounts for approximately 9% of the dose. Animal studies have shown that aprotinin is accumulated primarily in the kidney. Aprotinin, after being filtered by the glomeruli, is actively reabsorbed by the proximal tubules in which it is stored in phagolysosomes. Aprotinin is slowly degraded by lysosomal enzymes. The physiological renal handling of aprotinin is similar to that of other small proteins, e.g., insulin.



Clinical Trials



Repeat Coronary Artery Bypass Graft Patients:


Four placebo-controlled, double-blind studies of Trasylol® were conducted in the United States; of 540 randomized patients undergoing repeat coronary artery bypass graft (CABG) surgery, 480 were valid for efficacy analysis. The following treatment regimens were used in the studies:


Trasylol® Regimen A (2 million KIU IV loading dose, 2 million KIU into the pump prime volume, and 500,000 KIU per hour of surgery as a continuous intravenous infusion); Trasylol® Regimen B (1 million KIU IV loading dose, 1 million KIU into the pump prime volume, and 250,000 KIU per hour of surgery as a continuous intravenous infusion); a pump prime regimen (2 million KIU into the pump prime volume only); and a placebo regimen (normal saline). All patients valid for efficacy in the above studies were pooled by treatment regimen for analyses of efficacy.


In this pooled analysis, fewer patients receiving Trasylol®, either Regimen A or Regimen B, required any donor blood compared to the pump prime only or placebo regimens. The number of units of donor blood required by patients, the volume (milliliters) of donor blood transfused, the number of units of donor blood products transfused, the thoracic drainage rate, and the total thoracic drainage volumes were also reduced in patients receiving Trasylol® as compared to placebo.

Primary Coronary Artery Bypass Graft Patients:


Four placebo-controlled, double-blind studies of Trasylol® were conducted in the United States; of 1745 randomized patients undergoing primary CABG surgery, 1599 were valid for efficacy analysis. The dosage regimens used in these studies were identical to those used in the repeat CABG studies described above (Regimens A, B, pump prime, and placebo). All patients valid for efficacy were pooled by treatment regimen.


In this pooled analysis, fewer patients receiving Trasylol® Regimens A, B, and pump prime required any donor blood in comparison to the placebo regimen. The number of units of donor blood required by patients, the volume of donor blood transfused, the number of units of donor blood products transfused, the thoracic drainage rate, and total thoracic drainage volumes were also reduced in patients receiving Trasylol® as compared to placebo.

Additional subgroup analyses showed no diminution in benefit with increasing age. Male and female patients benefited from Trasylol® with a reduction in the average number of units of donor blood transfused. Although male patients did better than female patients in terms of the percentage of patients who required any donor blood transfusions, the number of female patients studied was small.


A double-blind, randomized, Canadian study compared Trasylol® Regimen A (n=28) and placebo (n=23) in primary cardiac surgery patients (mainly CABG) requiring cardiopulmonary bypass who were treated with aspirin within 48 hours of surgery. The mean total blood loss (1209.7 mL vs. 2532.3 mL) and the mean number of units of packed red blood cells transfused (1.6 units vs 4.3 units) were significantly less (p<0.008) in the Trasylol® group compared to the placebo group.


In a U.S. randomized study of Trasylol® Regimen A and Regimen B versus the placebo regimen in 212 patients undergoing primary aortic and/or mitral valve replacement or repair, no benefit was found for Trasylol® in terms of the need for transfusion or the number of units of blood required.



Indications and Usage for Trasylol


Trasylol® is indicated for prophylactic use to reduce perioperative blood loss and the need for blood transfusion in patients undergoing cardiopulmonary bypass in the course of coronary artery bypass graft surgery who are at an increased risk for blood loss and blood transfusion.



Contraindications


Hypersensitivity to aprotinin.


Administration of Trasylol® to patients with a known or suspected previous aprotinin exposure during the last 12 months is contraindicated. For patients with known or suspected history of exposure to aprotinin greater than 12 months previously, see WARNINGS. Aprotinin may also be a component of some fibrin sealant products and the use of these products should be included in the patient history.



Warnings


Anaphylactic or anaphylactoid reactions have occurred with Trasylol® administration, including fatal reactions in association with the initial (test) dose. The initial (test) dose does not fully predict a patient’s risk for a hypersensitivity reaction, including a fatal reaction. Fatal hypersensitivity reactions have occurred among patients who tolerated an initial (test) dose.


Hypersensitivity reactions often manifest as anaphylactic/anaphylactoid reactions with hypotension the most frequently reported sign of the hypersensitivity reaction. The hypersensitivity reaction can progress to anaphylactic shock with circulatory failure. If a hypersensitivity reaction occurs during injection or infusion of Trasylol®, administration should be stopped immediately and emergency treatment should be initiated. Even when a second exposure to aprotinin has been tolerated without symptoms, a subsequent administration may result in severe hypersensitivity/anaphylactic reactions.


Trasylol® should be administered only in operative settings where cardiopulmonary bypass can be rapidly initiated. Before initiating treatment with Trasylol®, the recommendations below should be followed to manage a potential hypersensitivity or anaphylactic reaction: 1) Have standard emergency treatments for hypersensitivity or anaphylactic reactions readily available in the operating room (e.g., epinephrine, corticosteroids). 2) Administration of the initial (test) dose and loading dose should be done only when the patient is intubated and when conditions for rapid cannulation and initiation of cardiopulmonary bypass are present. 3) Delay the addition of Trasylol® into the pump prime solution until after the loading dose has been safely administered.



Re-exposure to aprotinin: Administration of aprotinin, especially to patients who have received aprotinin in the past, requires a careful risk/benefit assessment because an allergic reaction may occur (see CONTRAINDICATIONS). Although the majority of cases of anaphylaxis occur upon re-exposure within the first 12 months, there are also case reports of anaphylaxis occurring upon re-exposure after more than 12 months.


In a retrospective review of 387 European patient records with documented re-exposure to Trasylol®, the incidence of hypersensitivity/anaphylactic reactions was 2.7%. Two patients who experienced hypersensitivity/anaphylactic reactions subsequently died, 24 hours and 5 days after surgery, respectively. The relationship of these 2 deaths to Trasylol® is unclear. This retrospective review also showed that the incidence of a hypersensitivity or anaphylactic reaction following re-exposure is increased when the re-exposure occurs within 6 months of the initial administration (5.0% for re-exposure within 6 months and 0.9% for re-exposure greater than 6 months). Other smaller studies have shown that in case of re-exposure, the incidence of hypersensitivity/anaphylactic reactions may reach the five percent level.


An analysis of all spontaneous reports from the Bayer Global database covering a period from 1985 to March 2006 revealed that of 291 possibly associated spontaneous cases of hypersensitivity (fatal: n=52 and non-fatal: n=239), 47% (138/291) of hypersensitivity cases had documented previous exposure to Trasylol®. Of the 138 cases with documented previous exposure, 110 had information on the time of the previous exposure. Ninety-nine of the 110 cases had previous exposure within the prior 12 months.



Renal Dysfunction: Trasylol® administration increases the risk for renal dysfunction and may increase the need for dialysis in the perioperative period. This risk may be especially increased for patients with pre-existing renal impairment or those who receive aminoglycoside antibiotics or drugs that alter renal function. Data from Bayer’s global pool of placebo-controlled studies in patients undergoing coronary artery bypass graft (CABG) surgery showed that the incidence of serum creatinine elevations >0.5 mg/dL above pre-treatment levels was statistically higher at 9.0% (185/2047) in the high-dose aprotinin (Regimen A) group compared with 6.6% (129/1957) in the placebo group. In the majority of instances, post-operative renal dysfunction was not severe and was reversible. However, renal dysfunction may progress to renal failure and the incidence of serum creatinine elevations >2.0 mg/dL above baseline was slightly higher in the high-dose aprotinin group (1.1% vs. 0.8%). Careful consideration of the balance of benefits versus potential risks is advised before administering Trasylol® to patients with impaired renal function (creatinine clearance < 60 mL/min) or those with other risk factors for renal dysfunction (such as perioperative administration of aminogylcoside or products that alter renal function). (See PRECAUTIONS and ADVERSE REACTIONS: Laboratory Findings: Serum Creatinine.)



Precautions



General:


Initial (Test) Dose: All patients treated with Trasylol® should first receive an initial (test) dose to minimize the extent of Trasylol® exposure and to help assess the potential for allergic reactions. Initiation of this initial (test) dose should occur only in operative settings where cardiopulmonary bypass can be rapidly initiated. The initial (test) dose of 1 mL Trasylol® should be administered intravenously at least 10 minutes prior to the loading dose and the patient should be observed for manifestations of possible hypersensitivity reaction. However, even after the uneventful administration of the initial 1 mL (test) dose, any subsequent dose may cause an anaphylactic reaction. If this happens, the infusion of Trasylol® should immediately be stopped and standard emergency treatment for anaphylaxis applied. It should be noted that serious, even fatal, hypersensitivity/anaphylactic reactions can also occur with administration of the initial (test) dose (see WARNINGS).



Allergic Reactions: Patients with a history of allergic reactions to drugs or other agents may be at greater risk of developing a hypersensitivity or anaphylactic reaction upon exposure to Trasylol® (see WARNINGS).


Loading Dose: The loading dose of Trasylol® should be given intravenously to patients in the supine position over a 20-30 minute period. Rapid intravenous administration of Trasylol® can cause a transient fall in blood pressure (see DOSAGE AND ADMINISTRATION).



Renal Dysfunction: Bayer’s global pool of placebo-controlled studies in patients undergoing CABG showed aprotinin administration was associated with elevations of serum creatinine values > 0.5 mg/dL above baseline. Careful consideration of the balance of benefits and risks is advised before administering aprotinin to patients with pre-existing impaired renal function or those with other risk factors for renal dysfunction. Serum creatinine should be monitored regularly following Trasylol® administration (see WARNINGS: Renal Dysfunction).


Use of Trasylol® in patients undergoing deep hypothermic circulatory arrest: Two U.S. case control studies have reported contradictory results in patients receiving Trasylol® while undergoing deep hypothermic circulatory arrest in connection with surgery of the aortic arch.


The first study showed an increase in both renal failure and mortality compared to age-matched historical controls. Similar results were not observed, however, in a second case control study. The strength of this association is uncertain because there are no data from randomized studies to confirm or refute these findings.



Drug Interactions:


Trasylol® is known to have antifibrinolytic activity and, therefore, may inhibit the effects of fibrinolytic agents.


In study of nine patients with untreated hypertension, Trasylol® infused intravenously in a dose of 2 million KIU over two hours blocked the acute hypotensive effect of 100mg of captopril.


Trasylol®, in the presence of heparin, has been found to prolong the activated clotting time (ACT) as measured by a celite surface activation method. The kaolin activated clotting time appears to be much less affected. However, Trasylol® should not be viewed as a heparin sparing agent (see Laboratory Monitoring of Anticoagulation During Cardiopulmonary Bypass).



Carcinogenesis, Mutagenesis, Impairment of Fertility:


Long-term animal studies to evaluate the carcinogenic potential of Trasylol® or studies to determine the effect of Trasylol® on fertility have not been performed.


Results of microbial in vitro tests using Salmonella typhimurium and Bacillus subtilis indicate that Trasylol® is not a mutagen.


Pregnancy: Teratogenic Effects: Pregnancy Category B:

Reproduction studies have been performed in rats at intravenous doses up to 200,000 KIU/kg/day for 11 days, and in rabbits at intravenous doses up to 100,000 KIU/kg/day for 13 days, 2.4 and 1.2 times the human dose on a mg/kg basis and 0.37 and 0.36 times the human mg/m2 dose. They have revealed no evidence of impaired fertility or harm to the fetus due to Trasylol®. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.



Nursing Mother:


Not applicable.



Pediatric Use:


Safety and effectiveness in pediatric patient(s) have not been established.



Geriatric Use:


Of the total of 3083 subjects in clinical studies of Trasylol®, 1100 (35.7 percent) were 65 and over, while 297 (9.6 percent) were 75 and over. Of patients 65 years and older, 479 (43.5 percent) received Regimen A and 237 (21.5 percent) received Regimen B. No overall differences in safety or effectiveness were observed between these subjects and younger subjects for either dose regimen, and other reported clinical experience has not identified differences in responses between the elderly and younger patients.



Laboratory Monitoring of Anticoagulation during Cardiopulmonary Bypass:


Trasylol® prolongs whole blood clotting times by a different mechanism than heparin. In the presence of aprotinin, prolongation is dependent on the type of whole blood clotting test employed. If an activated clotting time (ACT) is used to determine the effectiveness of heparin anticoagulation, the prolongation of the ACT by aprotinin may lead to an overestimation of the degree of anticoagulation, thereby leading to inadequate anticoagulation. During extended extracorporeal circulation, patients may require additional heparin, even in the presence of ACT levels that appear adequate.


In patients undergoing CPB with Trasylol® therapy, one of the following methods may be employed to maintain adequate anticoagulation:


1)

ACT - An ACT is not a standardized coagulation test, and different formulations of the assay are affected differently by the presence of aprotinin. The test is further influenced by variable dilution effects and the temperature experienced during cardiopulmonary bypass. It has been observed that Kaolin-based ACTs are not increased to the same degree by aprotinin as are diatomaceous earth-based (celite) ACTs. While protocols vary, a minimal celite ACT of 750 seconds or kaolin-ACT of 480 seconds, independent of the effects of hemodilution and hypothermia, is recommended in the presence of aprotinin. Consult the manufacturer of the ACT test regarding the interpretation of the assay in the presence of Trasylol®.

2)

Fixed Heparin Dosing - A standard loading dose of heparin, administered prior to cannulation of the heart, plus the quantity of heparin added to the prime volume of the CPB circuit, should total at least 350 IU/kg. Additional heparin should be administered in a fixed-dose regimen based on patient weight and duration of CPB.

3)

Heparin Titration - Protamine titration, a method that is not affected by aprotinin, can be used to measure heparin levels. A heparin dose response, assessed by protamine titration, should be performed prior to administration of aprotinin to determine the heparin loading dose. Additional heparin should be administered on the basis of heparin levels measured by protamine titration. Heparin levels during bypass should not be allowed to drop below 2.7 U/mL (2.0 mg/kg) or below the level indicated by heparin dose response testing performed prior to administration of aprotinin.

Protamine Administration - In patients treated with Trasylol®, the amount of protamine administered to reverse heparin activity should be based on the actual amount of heparin administered, and not on the ACT values.



Adverse Reactions


Studies of patients undergoing CABG surgery, either primary or repeat, indicate that Trasylol® is generally well tolerated. The adverse events reported are frequent sequelae of cardiac surgery and are not necessarily attributable to Trasylol® therapy. Adverse events reported, up to the time of hospital discharge, from patients in US placebo-controlled trials are listed in the following table. The table lists only those events that were reported in 2% or more of the Trasylol® treated patients without regard to causal relationship.

Myocardial Infarction: In the pooled analysis of all patients undergoing CABG surgery, there was no significant difference in the incidence of investigator-reported myocardial infarction (MI) in Trasylol® treated patients as compared to placebo treated patients. However, because no uniform criteria for the diagnosis of myocardial infarction were utilized by investigators, this issue was addressed prospectively in three later studies (two studies evaluated Regimen A, Regimen B and Pump Prime Regimen; one study evaluated only Regimen A), in which data were analyzed by a blinded consultant employing an algorithm for possible, probable or definite MI. Utilizing this method, the incidence of definite myocardial infarction was 5.9% in the aprotinin-treated patients versus 4.7% in the placebo treated patients. This difference in the incidence rates was not statistically significant. Data from these three studies are summarized below.

Although there was a statistically significantly increased risk of graft closure for Trasylol® treated patients compared to patients who received placebo (p=0.035), further analysis showed a significant treatment by site interaction for one of the non-U.S. sites vs. the U.S. centers. When the analysis of graft closures was repeated for U.S. centers only, there was no statistically significant difference in graft closure rates in patients who received Trasylol® vs. placebo. These results are the same whether analyzed as the proportion of patients who experienced at least one graft closure postoperatively or as the proportion of grafts closed. There were no differences between treatment groups in the incidence of myocardial infarction as evaluated by the blinded consultant (2.9% Trasylol® vs. 3.8% placebo) or of death (1.4% Trasylol® vs. 1.6% placebo) in this study.
