Nitrendipine

Nitrendipine is a dihydropyridine calcium channel blocker with an IC50 of 95 nM.It is an investigational dihydropyridine calcium-channel antagonist for the treatment of hypertension. Nitrendipine and BRL 38227 cause concentration-related inhibitions of the inositol phosphate response to histamine (100 uM). Similar maximal inhibitions were caused by each agent (55-58%). Inhibitory effect of BRL 38227 was reduced in potency (IC50 = 5.5 uM), but not magnitude, in the presence of glibenclamide (0.5 uM).
