Background Information

Felodipine is an L-type (CaV1), voltage-gated Ca2+ channels are plasma membrane protein.Felodipine is a DHP that acts as L-type, voltage-gated Ca2+ channel blocker that is selective over N-, R-, P/Q- and T-type channels. ......by Affix Scientific
Felodipine is a selective L-type Ca2+ channel blocker with IC50 of 0.15 nM. ......by BOC Sciences
Felodipine is a selective L-type Ca2+ channel blocker with IC50 of 0.15 nM. ......by Selleck Chemicals LLC
A dihydropyridine calcium antagonist with positive inotropic effects. It lowers blood pressure by reducing peripheral vascular resistance through a highly selective action on smooth muscle in arteriolar resistance vessels. ......by Target Molecule Corp.
L-type Ca2+ channel blocker that is selective over N-, R-, P/Q- and T-type channels. Displays high vascular selectivity; lowers arterial blood pressure without altering cardiac contractility. Antihypertensive. ......by Tocris Bioscience Inc.
