PRESCRIPTION DRUG
Enalapril maleate is indicated for the treatment of hypertension. Enalapril maleate is effective alone or in combination with other antihypertensive agents, especially thiazide-type diuretics. The blood pressure lowering effects of enalapril maleate and thiazides are approximately additive. Enalapril maleate is indicated for the treatment of symptomatic congestive heart failure, usually in combination with diuretics and digitalis. In these patients enalapril maleate improves symptoms, increases survival, and decreases the frequency of hospitalization (see CLINICAL PHARMACOLOGY, for details and limitations of survival trials). In clinically stable asymptomatic patients with left ventricular dysfunction (ejection fraction ≤35 percent), enalapril maleate decreases the rate of development of overt heart failure and decreases the incidence of hospitalization for heart failure. (See CLINICAL PHARMACOLOGY, for details and limitations of survival trials.) In using enalapril maleate, consideration should be given to t

ENALAPRIL MALEATE - ENALAPRIL MALEATE TABLET UNIT DOSE SERVICES ---------- Product Information Rx only ENALAPRIL MALEATE TABLETS, USP When pregnancy is detected, enalapril maleate should be discontinued as soon as possible. See WARNINGS, USE IN PREGNANCY WHEN USED IN PREGNANCY DURING THE SECOND AND THIRD TRIMESTERS, ACE INHIBITORS CAN CAUSE INJURY AND EVEN DEATH TO THE DEVELOPING FETUS. _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 202825444 adrenal cortex. The beneficial effects of enalapril in hypertension and heart failure appear to result primarily from suppression of the renin -angiotensin-aldosterone system. Inhibition of ACE results in decreased plasma angiotens Pročitajte cijeli dokument
