PERINDOPRIL - A REVIEW OF ITS PHARMACOLOGICAL PROPERTIES AND THERAPEUTIC USE IN CARDIOVASCULAR DISORDERS

Perindopril is a long acting angiotensin converting enzyme (ACE) inhibitor, which displays similar pharmacodynamic properties to other agents in this class. In common with enalapril, it is also a prodrug. After absorption, perindopril is hydrolysed to the active metabolite, perindoprilat, and with once daily administration adequate 24-hour inhibition of ACE is obtained. Perindopril 4 to 8mg once daily is usually effective for blood pressure control in patients with mild to moderate essential hypertension. Those patients who do not respond adequately to monotherapy with perindopril usually respond with the addition of a second agent, such as a thiazide diuretic. General practice trials indicate that perindopril is at least as effective and as well tolerated as usual therapeutic dosages of captopril, atenolol or hydrochlorothiazide plus amiloride in mild to moderate essential hypertension. Preliminary results indicate that perindopril may also be effective in patients with severe hypertension or congestive heart failure. Peridopril is generally well tolerated and has an adverse effect profile similar to that of other ACE inhibitors. If further clinical experience confirms initial findings, perindopril is likely to represent a useful alternative to other members of the ACE inhibitor class in all grades of hypertension and congestive heart failure.
