Nimodipine is a calcium channel blocker that is used to prevent or treat cerebral vasospasm after

subarachnoid hemorrhage. It works by relaxing the smooth muscle of the cerebral arteries and

improving blood flow to the brain. Nimodipine is the only FDA-approved agent for vasospasm and

has been shown to reduce the risk of ischemic complications and improve neurological outcomes12.

Lorazepam, propranolol, and pentobarbital are not effective for treating cerebral vasospasm and may

have adverse effects on the patient’s blood pressure, heart rate, and level of consciousness.
