Biological Activity for Isradipine

Isradipine is a potent and selective L-type voltage-gated Ca²⁺ channel blocker. EC₅₀ and pA₂ values are 1.4 nM and 10.3 for relaxation of depolarization- and Ca²⁺-induced contractions of rabbit aorta respectively; EC₂₅ = 0.45 nM for reduction in rate of spontaneously beating guinea pig right atria. Long-acting antihypertensive agent in vivo, exerting primary effects on vascular tissue with secondary negative chronotropic action.
