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.^[2] 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.
