Devapamil is a calcium channel blocker. It is also known as desmethoxyverapamil, which is a phenylalkylamine (PAA) derivative.[1] Devapamil not only inhibits by blocking the calcium gated channels, but also by depolarizing the membrane during the sodium-potassium exchanges.[2]

Structure

Devapamil consists of two aromatic rings with methoxy substituents connected by an alkylamine chain increasing flexibility and overall potency.[3]

Animal studies

Devapamil in rats can be used to decrease glutathione levels and increase oxidation of lipids, which makes it effective in preclusion of ulcers caused by stress.[4][5] The medical characteristics of this drug, and other phenylalkylamines, depends greatly on the state of the calcium channels being targeted which results in a greater affinity and drug efficiency.
