Calcium channel blockers

These agents are administered to minimize sequelae of cerebral vasospasm.

Nimodipine (Nimotop)

For improvement of neurological impairments resulting from spasms following SAH caused by ruptured congenital intracranial aneurysm in patients in good postictal neurological condition.

While studies show benefit in severity of neurological deficits caused by cerebral vasospasm following SAH, no evidence shows that the drug either prevents or relieves spasm of cerebral arteries. Actual mechanism of action unknown but may involve protection of brain against ischemia.

Therapy should start within 96 h of SAH. If capsule cannot be swallowed because patient undergoing surgery or unconscious, a hole can be made at both ends of capsule with 18-gauge needle, and contents extracted into a syringe. Contents then can be emptied into patient's nasogastric tube in situ and washed down tube with 30 mL isotonic saline.
