Accupril® (Quinapril Hydrochloride Tablets) WARNING: FETAL TOXICITY
ثبت نشده
چکیده
Mechanism of Action: Quinapril is deesterified to the principal metabolite, quinaprilat, which is an inhibitor of ACE activity in human subjects and animals. ACE is a peptidyl dipeptidase that catalyzes the conversion of angiotensin I to the vasoconstrictor, angiotensin II. The effect of quinapril in hypertension and in congestive heart failure (CHF) appears to result primarily from the inhibition of circulating and tissue ACE activity, thereby reducing angiotensin II formation. Quinapril inhibits the elevation in blood pressure caused by intravenously administered angiotensin I, but has no effect on the pressor response to angiotensin II, norepinephrine or epinephrine. Angiotensin II also stimulates the secretion of aldosterone from the adrenal cortex, thereby facilitating renal sodium and fluid reabsorption. Reduced aldosterone secretion by quinapril may result in a small increase in serum potassium. In controlled hypertension trials, treatment with ACCUPRIL alone resulted in mean increases in potassium of 0.07 mmol/L (see

متن کاملPreclinical toxicology studies with the angiotensin-converting enzyme inhibitor quinapril hydrochloride (Accupril).
Acute, subacute, and chronic toxicity studies, carcinogenicity bioassays, and reproductive and genetic toxicology studies were performed with quinapril, an ACE inhibitor used in the treatment of hypertension. Acute toxicity is minimal in rodents, and repeated dosing elicits gastric irritation, juxtaglomerular apparatus (JGA) hypertrophy and hyperplasia and tubular degenerative changes in the ki...

Its empirical formula is C24H28N2O5•HCl, and its molecular weight is 460.96. Benazeprilat, the active metabolite of benazepril, is a non-sulfhydryl angiotensin-converting enzyme inhibitor. Benazepril is converted to benazeprilat by hepatic cleavage of the ester group. Lotensin is supplied as tablets containing 5 mg, 10 mg, 20 mg, and 40 mg of benazepril hydrochloride for oral administration. Th...
