From Dog

Imidapril is an angiotensin-converting enzyme inhibitor similar to benazepril.

This drug is primarily indicated for dogs with congestive heart failure, such as observed with mitral valve endocardiosis[1].

Although some side-effects have been reported, it is efficacious as other ACE inhibitors and appears to be well tolerated in dogs[2].

Imidapril also has cardioprotective effects against ischemia-reperfusion injury by decreasing infarct size, and through the antiarrhythmic effect and the reversal of increased overall contractility[3].

Recommended dose rate in dogs is 0.25 - 0.5 mg/kg given orally once daily[4].
