Moexipril - A review of its use in the management of essential hypertension

Moexipril is a prodrug which is hydrolysed after oral administration to its active metabolite moexiprilat, an inhibitor of the angiotensin converting enzyme (ACE). Once daily administration of moexipril 7.5 or 15 mg effectively reduces blood pressure in patients with essential hypertension (including the elderly and postmenopausal women with this condition). In double-blind randomised comparative studies, moexipril 7.5 to 15 mg once daily showed similar efficacy to other antihypertensive agents, including captopril, hydrochlorothiazide, atenolol, metoprolol, sustained release verapamil and nitrendipine. Combined therapy with hydrochlorothiazide and moexipril had a significantly greater antihypertensive effect than either agent alone. Moexipril is well tolerated by the majority of patients and compares well in this respect with other antihypertensive agents. Its tolerability profile appears to be characteristic of ACE inhibitors as a class (the most common adverse events being headache, symptoms of upper respiratory tract infection and cough). Moexipril generally had no clinically significant effect on lipid, glucose or electrolyte metabolism or haematological parameters, and, in particular, it was not associated with any significant changes in lipid or glucose metabolism in postmenopausal women (with or without hormone replacement therapy). Conclusions. Once daily moexipril is a useful agent for the treatment of essential hypertension, which compares will with currently available options in terms of clinical efficacy and tolerability. In addition, clinical experience to date supports its use in postmenopausal women.
