Mechanism of action
It inhibits the movement calcium ions in vascular smooth cells and cardiac muscle. It binds to dihydropyridine and nondihydropyridine binding sites. This causes decreased heart muscle heart muscle contractility. It also causes a reduction in peripheral vascular resistance and reduction in blood pressure. It also acts as inhibitor of acid sphingomyelinase which is involved in signal transduction and programmed cell death.
It produces its action by competing with sympathomimetic neurotransmitter for binding of the beta adrenergic receptor which is present in heart and vascular smooth muscle. This causes reduction in heart rate.
