Fosinoprilat is a phosphinic acid-containing angiotensin-converting enzyme (ACE) inhibitor with antihypertensive activity. Fosinoprilat specifically and competitively inhibits angiotensin-converting enzyme thereby decreasing the formation of the potent vasoconstrictor angiotensin II, resulting in diminished vasopressor activity. In addition, angiotensin II-mediated aldosterone secretion by adrenal cortex is decreased, which results in a decrease of sodium retention and an increase in water outflow.
Fosinoprilat is an Angiotensin Converting Enzyme Inhibitor. The mechanism of action of fosinoprilat is as an Angiotensin-converting Enzyme Inhibitor.

4 Pharmacology and Biochemistry
4.1 MeSH Pharmacological Classification

Angiotensin-Converting Enzyme Inhibitors

A class of drugs whose main indications are the treatment of hypertension and heart failure. They exert their hemodynamic effect mainly by inhibiting the renin-angiotensin system. They also modulate sympathetic nervous system activity and increase prostaglandin synthesis. They cause mainly vasodilation and mild natriuresis without affecting heart rate and contractility. (See all compounds classified as Angiotensin-Converting Enzyme Inhibitors.)


Antihypertensive Agents

Drugs used in the treatment of acute or chronic vascular HYPERTENSION regardless of pharmacological mechanism. Among the antihypertensive agents are DIURETICS; (especially DIURETICS, THIAZIDE); ADRENERGIC BETA-ANTAGONISTS; ADRENERGIC ALPHA-ANTAGONISTS; ANGIOTENSIN-CONVERTING ENZYME INHIBITORS; CALCIUM CHANNEL BLOCKERS; GANGLIONIC BLOCKERS; and VASODILATOR AGENTS. (See all compounds classified as Antihypertensive Agents.)


Anti-Arrhythmia Agents

Agents used for the treatment or prevention of cardiac arrhythmias. They may affect the polarization-repolarization phase of the action potential, its excitability or refractoriness, or impulse conduction or membrane responsiveness within cardiac fibers. Anti-arrhythmia agents are often classed into four main groups according to their mechanism of action: sodium channel blockade, beta-adrenergic blockade, repolarization prolongation, or calcium channel blockade. (See all compounds classified as Anti-Arrhythmia Agents.)
