What is "nimodipine"

n. A dihydropyridine calcium channel blocker originally developed for the treatment of high blood pressure and now mostly used to prevent vasospasm.

Nimodipine (marketed by Bayer as Nimotop) is a dihydropyridine calcium channel blocker originally developed for the treatment of high blood pressure. It is not frequently used for this indication, but has shown good results in preventing a major complication of subarachnoid hemorrhage (a form of cerebral hemorrhage) termed vasospasm; this is now the main use of nimodipine.
