Barnidipine

Barnidipine (INN; also known as mepirodipine) is a calcium channel blocker which belongs to the dihydropyridine (DHP) group of calcium channel blockers. It is used in the treatment of hypertension.

Pharmacodynamics
Barnidipine is a pure S,S isomer, a lipophilic 1,4-dihydropyridine calcium channel blocker, which, like other compounds in the class, shows a high affinity for calcium channels, particularly the L-type slow channels of smooth muscle cells found in the vessel wall. Calcium channel blocking drugs have the characteristic of interfering with the flow of calcium ions into the interior of cells through the slow channels of the plasma membrane.
