When pregnancy is detected, enalapril maleate should be discontinued as soon as possible. See WARNINGS, _Fetal / Neonatal Morbidity and Mortality._ DESCRIPTION Enalapril maleate is the maleate salt of enalapril, the ethyl ester of a long-acting angiotensin converting enzyme inhibitor, enalaprilat. Enalapril maleate is chemically described as L-Proline,1-[N-[1- (ethoxycarbonyl)-3-phenylpropyl]-L-alanyl]- , (S)-, (Z)-2-butenedioate (1:1). Its molecular formula is, C H N O ·C H O , and its structural formula is: Enalapril maleate is a white to off-white, crystalline powder with a molecular weight of 492.53. It is sparingly soluble in water, soluble in ethanol, and freely soluble in methanol. Enalapril is a pro-drug; following oral administration, it is bioactivated by hydrolysis of the ethyl ester to enalaprilat, which is the active angiotensin converting enzyme inhibitor. Enalapril maleate is supplied as 2.5 mg, 5 mg,10 mg and 20 mg tablets for oral administration. In addition, each tablet contains the following inactive ingredients: hypromellose, anhydrous lactose, corn starch, stearic acid and talc. The 10 mg and 20 mg tablets also contain iron oxides. CLINICAL PHARMACOLOGY MECHANISM OF ACTION Enalapril, after hydrolysis to enalaprilat, inhibits angiotensin-converting enzyme (ACE) in human subjects and animals. ACE is a peptidyl dipeptidase that catalyzes the conversion of angiotensin I to the vasoconstrictor substance, angiotensin II. Angiotensin II also stimulates aldosterone secretion by the adrenal cortex. The beneficial effects of enalapril in hypertension and heart failure appear to result primarily from suppression of the renin -angiotensin-aldosterone system.
