Nifedipin T20 retard

Nifedipine is a calcium antagonist of the dihydropyridine type. Nifedipine is relatively selective for the blood vessels with far lower effect on hear muscle cells as compared to the smooth muscle surrounding the blood vessels. Nifedipine has therefore no direct effect on heart contractility and impulse conductivity when in normal clinical doses.
