The safety experience in U.S. placebo-controlled trials included 1069 hypertensive patients, of whom 832 received MAVIK. Nearly 200 hypertensive patients received MAVIK for over one year in open-label trials. In controlled trials, withdrawals for adverse events were 2.1% on placebo and 1.4% on MAVIK. Adverse events considered at least possibly related to treatment occurring in 1% of MAVIK-treated patients and more common on MAVIK than placebo, pooled for all doses, are shown below, together with the frequency of discontinuation of treatment because of these events.

ADVERSE EVENTS IN PLACEBO-CONTROLLED HYPERTENSION TRIALS

Headache and fatigue were all seen in more than 1% of MAVIK-treated patients but were more frequently seen on placebo. Adverse events were not usually persistent or difficult to manage.

Left Ventricular Dysfunction Post Myocardial Infarction

Adverse reactions related to MAVIK occurring at a rate greater than that observed in placebo-treated patients with left ventricular dysfunction, are shown below. The incidences represent the experiences from the TRACE study. The follow-up time was between 24 and 50 months for this study.

Percentage of Patients with Adverse Events Greater Than Placebo

Clinical adverse experiences possibly or probably related or of uncertain relationship to therapy occurring in 0.3% to 1.0% (except as noted) of the patients treated with MAVIK (with or without concomitant calcium ion antagonist or diuretic) in controlled or uncontrolled trials (N=1134) and less frequent, clinically significant events seen in clinical trials or post-marketing experience include (listed by body system):

General Body Function

Chest pain.

Cardiovascular

AV first degree block, bradycardia, edema, flushing, and palpitations.

Central Nervous System

Drowsiness, insomnia, paresthesia, vertigo.

Dermatologic

Pruritus, rash, pemphigus.

Eye, Ear, Nose, Throat

Epistaxis, throat inflammation, upper respiratory tract infection.

Emotional, Mental, Sexual States

Anxiety, impotence, decreased libido.

Gastrointestinal

Abdominal distention, abdominal pain/cramps, constipation, dyspepsia, diarrhea, vomiting, nausea.

Hemopoietic

Decreased leukocytes, decreased neutrophils.

Metabolism and Endocrine

Increased liver enzymes including SGPT (ALT).

Musculoskeletal System

Extremity pain, muscle cramps, gout.

Pulmonary

Dyspnea.

Postmarketing

The following adverse reactions were identified during post approval use of MAVIK. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

General Body Function

Malaise, fever.

Cardiovascular

Myocardial infarction, myocardial ischemia, angina pectoris, cardiac failure, ventricular tachycardia, tachycardia, transient ischemic attack, arrhythmia.

Central Nervous System

Cerebral hemorrhage.

Dermatologic

Alopecia, sweating, Stevens-Johnson syndrome and toxic epidermal necrolysis.

Emotional, Mental, Sexual States

Hallucination, depression.

Gastrointestinal

Dry mouth, pancreatitis, jaundice and hepatitis.

Hemopoietic

Agranulocytosis, pancytopenia.

Metabolism and Endocrine

Increased SGOT (AST).

Pulmonary

Bronchitis.

Renal and Urinary

Renal failure.

Clinical Laboratory Test Findings

Hematology

Thrombocytopenia.

Serum Electrolytes

Hyponatremia.

Creatinine and Blood Urea Nitrogen

Increases in creatinine levels occurred in 1.1% of patients receiving MAVIK alone and 7.3% of patients treated with MAVIK, a calcium ion antagonist and a diuretic. Increases in blood urea nitrogen levels occurred in 0.6% of patients receiving MAVIK alone and 1.4% of patients receiving MAVIK, a calcium ion antagonist, and a diuretic. None of these increases required discontinuation of treatment. Increases in these laboratory values are more likely to occur in patients with renal insufficiency or those pretreated with a diuretic and, based on experience with other ACE inhibitors, would be expected to be especially likely in patients with renal artery stenosis (see PRECAUTIONS and WARNINGS).

Liver Function Tests

Occasional elevation of transaminases at the rate of 3X upper normals occurred in 0.8% of patients and persistent increase in bilirubin occurred in 0.2% of patients. Discontinuation for elevated liver enzymes occurred in 0.2% of patients.

Other

Another potentially important adverse experience, eosinophilic pneumonitis, has been attributed to other ACE inhibitors.

Concomitant Diuretic Therapy

As with other ACE inhibitors, patients on diuretics, especially those on recently instituted diuretic therapy, may experience an excessive reduction of blood pressure after initiation of therapy with MAVIK. The possibility of exacerbation of hypotensive effects with MAVIK may be minimized by either discontinuing the diuretic or cautiously increasing salt intake prior to initiation of treatment with MAVIK. If it is not possible to discontinue the diuretic, the starting dose of trandolapril should be reduced (see DOSAGE AND ADMINISTRATION).

Agents Increasing Serum Potassium

Trandolapril can attenuate potassium loss caused by thiazide diuretics and increase serum potassium when used alone. Use of potassium-sparing diuretics (spironolactone, triamterene, or amiloride), potassium supplements, or potassium-containing salt substitutes concomitantly with ACE inhibitors can increase the risk of hyperkalemia. If concomitant use of such agents is indicated, they should be used with caution and with appropriate monitoring of serum potassium (see PRECAUTIONS).

Antidiabetic Agents

Concomitant use of ACE inhibitors and antidiabetic medicines (insulin or oral hypoglycemic agents) may cause an increased blood glucose lowering effect with greater risk of hypoglycemia.

Lithium

Increased serum lithium levels and symptoms of lithium toxicity have been reported in patients receiving concomitant lithium and ACE inhibitor therapy. These drugs should be coadministered with caution, and frequent monitoring of serum lithium levels is recommended. If a diuretic is also used, the risk of lithium toxicity may be increased.

Gold

Nitritoid reactions (symptoms include facial flushing, nausea, vomiting and hypotension) have been reported rarely in patients on therapy with injectable gold (sodium aurothiomalate) and concomitant ACE inhibitor therapy including MAVIK.

Other

No clinically significant pharmacokinetic interaction has been found between trandolaprilat and food, cimetidine, digoxin, or furosemide.

The anticoagulant effect of warfarin was not significantly changed by trandolapril.

As with all other inhibitors of RAS, NSAIDs may reduce the antihypertensive effects of trandolapril. Blood pressure monitoring should be increased when any NSAID is added or discontinued in a patient treated with trandolapril.

The hypotensive effect of certain inhalation anesthetics may be enhanced by ACE inhibitors including trandolapril (see PRECAUTIONS-Surgery/Anesthesia).
