Pharmacodynamics | Flunarizine is a selective calcium entry blocker with calmodulin binding properties and histamine H1 blocking activity. |
Mechanism of action | Flunarizine inhibits the influx of extracellular calcium through myocardial and vascular membrane pores by physically plugging the channel. The decrease in intracellular calcium inhibits the contractile processes of smooth muscle cells, causing dilation of the coronary and systemic arteries, increas... |
