Enalapril maleate and hydrochlorothiazide combines an angiotensin converting enzyme inhibitor, enalapril maleate, and a diuretic, hydrochlorothiazide. 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 ( S )-1-[ N -[1-(ethoxycarbonyl)-3-phenylpropyl]-L-alanyl]-L-proline, ( Z )-2-butenedioate salt (1:1). Its empirical formula is C 20 H 28 N 2 O 5 ∙C 4 H 4 O 4 , 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. Hydrochlorothiazide is 6-chloro-3,4-dihydro-2 H -1,2,4-benzothiadiazine-7-sulfonamide 1,1-dioxide. Its empirical formula is C 7 H 8 ClN 3 O 4 S 2 and its structural formula is: It is a white, or practically white, crystalline powder with a molecular weight of 297.74, which is slightly soluble in water, but freely soluble in sodium hydroxide solution. Enalapril maleate and hydrochlorothiazide is available in two tablet combinations of enalapril maleate with hydrochlorothiazide: enalapril maleate and hydrochlorothiazide 5/12.5 mg, containing 5 mg enalapril maleate and 12.5 mg hydrochlorothiazide and contain the following inactive ingredients: ferric oxide black, ferric oxide yellow, lactose monohydrate, magnesium stearate, pregelatinized starch, purified water, and sodium bicarbonate. Enalapril maleate and hydrochlorothiazide 10/25 mg, containing 10 mg enalapril maleate and 25 mg hydrochlorothiazide and contain the following inactive ingredients: ferrix oxide yellow, ferric oxide red, lactose monohydrate, magnesium stearate, pregelatinized starch, purified water, and sodium bicarbonate.
