ABSTRACT
Enalapril, a long-acting, non-sulfhydryl, angiotensin converting enzyme (ACE) inhibitor, is well absorbed after oral administration, and hydrolised to its bioactive form, enalaprilic acid (EA). Administration with food does not affect its bioavailability; elimination is predominantly renal. Peak serum EA concentrations occur 4 h after an oral dose; its serum half-life is approximately 35 h, and steady state is achieved by the fourth day of treatment. Enalapril controls blood pressure in essential and renovascular hypertension without affecting heart rate or cardiovascular reflexes. It also decreases serum concentrations of ACE (for greater than 24 h), angiotensin II and aldosterone, and increases plasma renin activity. Once and twice-daily regimens are equally effective. In patients with congestive heart failure refractory to digitalis and diuretics, enalapril increases cardiac output and decreases pulmonary capillary wedge pressure. Long-term treatment produces improvement in NYHA functional classification, exercise capacity and ejection fraction. Human experience to date indicates that enalapril is safe and well tolerated.
