Description
Spirapril is an ACE inhibitor antihypertensive drug used to treat hypertension. Like many ACE inhibitors, this is a prodrug which is converted to the active metabolite spiraprilat following oral administration. ACE inhibitors are used primarily in treatment of hypertension and congestive heart failure.
Indication
Spirapril is an ACE inhibitor class drug used to treat hypertension.
Pharmacology
Spirapril is an angiotensin-converting enzyme (ACE) inhibitor. ACE is a peptidyl dipeptidase that catalyzes the conversion of angiotensin I to the vasoconstrictor substance, angiotensin II. By blocking ACE, spirapril decreases angiotensin II which is a vasoconstrictor and inducer of aldosterone. So by inhibiting the enzymes, aldosterone secreation is decreased (so less sodium is reabsorbed) and there is a decrease in vasoconstriction. Combined, this leades to a decrease in blood pressure.
Affected Organisms
Humans and other mammals
Biotransformation
Hepatic. Converted to spiraprilat following oral administration.
Absorption
Bioavailability is 50% following oral administration.
Half Life
30 to 35 hours
