Mechanism

Imidapril is a long-acting prodrug ACE inhibitor. After absorption and conversion to its active form, it inhibits Angiotensin Converting Enzyme (ACE), preventing the conversion of Angiotensin I to Angiotensin II, thereby reducing Ang II's vasoconstrictive and aldosterone-stimulating effects. It also increases plasma kinin levels by inhibiting ACE's kininase activity, contributing to vasodilation.
