Nimodipine

Nimodipine (Nimotop) is a dihydropyridine derivative and an analogue of the calcium channel blocker nifedipine, with antihypertensive activity.Nimodipine decreases intracellular free Ca2+, Beclin-1 and autophagy. (In Vitro) :Nimodipine (1.5~150 μg/ml; 15 minutes; B16a and W256 cells) results in a dose-dependent inhibition of B16a and W256 tumor-cell-induced platelet aggregation. Nimodipine is also inhibitory in a homologous system. (In Vivo) :Nimodipine (0.2 μg/μl, intrathecal administration) prevents subarachnoid hemorrhage-associated cerebral vasospasm by prophylactic continuous intrathecal administration.Nimodipine (0.1~80 mg/kg; p.o.) results in a significant dose-dependent inhibition of spontaneous metastasis.
