Moexiprilat is the pharmacologically active metabolite of Moexipril. Formation of Moexiprilat is caused by hydrolysis of a Moexipril’s ethyl ester group. Moexiprilat competitively inhibits ACE, thereby blocking the conversion of angiotensin I to angiotensin II. This prevents the actions of the potent vasoconstrictor angiotensin II and leads to vasodilatation. This agent also prevents angiotensin II-induced aldosterone secretion by the adrenal cortex, thereby promoting diuresis and natriuresis. Moexiprilat showed an extended duration of action owing to a long terminal pharmacokinetic half-life and produced a persistent ACE inhibition.

-Patients receiving diuretic therapy: 3.75 mg orally once a day 1 hour before meals
Maintenance dose: 7.5 to 30 mg orally per day in 1 or 2 divided doses 1 hour before meals.
Maximum dose: 60 mg/day
Route of Administration:
Oral
In vitro, moexiprilat (active diacid metabolite of moexipril) was a potent inhibitor of ACE in guinea pig serum as well as on purified ACE from rabbit lung with IC50 values of 2.6 and 4.9 nmol/l, respectively. Both, moexipril and moexiprilat inhibited the angiotensin I (ANG I)-induced contractions of rabbit aorta concentration-dependently.
