Imidapril also known as Imidaprilum is an ACE inhibitor.



Imidapril prevents the conversion of angiotensin I to angiotension II by inhibiting ACE. It may also inhibit the degradation of bradykinin. It reduces preload and afterload in heart failure, and reduces left ventricular remodelling in MI.

Absorption Absorption of Imidapril is about 70%; peak plasma levels of Imidaprilat reached in about 7 hr. Distribution Protein-binding: 85% (Imidapril); 53% (Imidaprilat).

Metabolism Imidapril is hydrolysed to Imidaprilat in the liver.

Excretion 40% of an oral dose is excreted renally, the remaining dose in the faeces. Terminal half-life: >24 hr (Imidaprilat).
