Because it has some selectivity for cerebral vasculature, nimodipine's main use is in the prevention of cerebral vasospasm and resultant ischemia , a complication of subarachnoid hemorrhage (a form of cerebral bleed ), specifically from ruptured intracranial berry aneurysms irrespective of the patient's post-ictus neurological condition.  Its administration begins within 4 days of a subarachnoid hemorrhage and is continued for three weeks. If blood pressure drops by over 5%, dosage is adjusted. There is still controversy regarding the use of intravenous nimodipine on a routine basis.
