Imidapril

**Semantic type:** Pharmacologic Substance

**Definition:** An angiotensin-converting enzyme (ACE) inhibitor with antihypertensive activity. As a prodrug, imidapril is converted by hydrolysis in the liver into its active form imidaprilat. Imidaprilat competitively binds to and inhibits ACE, thereby blocking the conversion of angiotensin I to angiotensin II. This prevents the potent vasoconstrictive actions of angiotensin II and results in vasodilation. Imidaprilat also decreases angiotensin II-induced aldosterone secretion by the adrenal cortex, which leads to an increase in sodium excretion and subsequently increases water outflow.

**Synonyms:** - (S)-3-(N-((S)-1-Ethoxycarbonyl-3-phenylpropyl)-L-alanyl)-1-methyl-2-oxoimidazoline-4-carboxylic acid - IMIDAPRIL
