Trandolapril is a non-sulfhydryl angiotensin-converting enzyme (ACE) inhibitor with antihypertensive activity. As a prodrug, trandolapril is converted by de-esterification in the liver into its active form trandolaprilat. Trandolaprilat competitively binds to and inhibits ACE, thereby blocking the conversion of angiotensin I to angiotensin II. This prevents the potent vasoconstrictive actions of angiotensin II and results in vasodilation. Trandolaprilat also decreases angiotensin II-induced aldosterone secretion by the adrenal cortex, which leads to an increase in sodium excretion and subsequently increases water outflow.
Trandolapril has a favourable pharmacological profile and an antihypertensive efficacy at least comparable to that of other ACE inhibitors. The pharmacological characteristics of trandolapril allow it to provide good 24-hour control of BP with once-daily administration. Trandolapril has also demonstrated some efficacy in a small number of patients with CHF. In addition, trandolapril provides long term protection against all-cause mortality in patients with LV dysfunction after MI. The results of the Prevention of Events with Angiotensin Converting Enzyme Inhibition (PEACE) study will determine its potential as a cardioprotective agent in patients with coronary artery disease and preserved LV function. Thus, trandolapril represents an effective, well-tolerated and convenient treatment option for patients with mild to moderate hypertension or LV systolic dysfunction after MI.
Trandolapril. An update of its pharmacology and therapeutic use in cardiovascular disorders.
Trandolapril is a well known angiotensin converting enzyme (ACE) inhibitor with many cardiovascular (CV) indications. The objectives of this article are to review the pharmacokinetics and pharmacodynamics properties of trandolapril and to focus on its clinical relevance in cardiovascular medicine. Various populations have been studied in large clinical trials including patients with congestive heart failure (CHF) after an acute myocardial infarction (AMI), diabetics, patients with hypertension (HTN), stable coronary artery disease (CAD) and prevention of proteinuria. Long-term treatment with trandolapril in patients with reduced left ventricular function soon after AMI significantly reduced the risk of overall mortality, mortality from CV causes, sudden death, and the development of severe CHF. Treatment with trandolapril after AMI complicated by left ventricular dysfunction appears to be of considerable importance in patients with diabetes mellitus by saving lives and substantially reducing the risk of progression to severe CHF as well. Moreover, trandolapril reduces progression to proteinuria in high-risk patients. Some of the advantages of trandolapril over other ACE inhibitors are the wide spectrum of patient populations studied, the well established dosage and its proven trough-to-peak effect ratios permitting a safe once-a-day administration.
