Prospective, double-blind, randomized, stratified, placebo-controlled trial of 125 patients at 5 centers. Patients stratified by center and treating physician.
Patients were randomized to receive a gelatin capsule containing either nimodipine or placebo. When patients could not take the capsules orally, the liquid within the capsules was delivered by nasogastric tube. The initial dose was 0.7 mg/ kg. Subsequent doses were 0.35 mg/kg every four hours for 21 days. Amount of blood in basal subarachnoid spaces on CAT scan prior to entry was measured.
|Type||Measure||Time Frame||Safety Issue|
|Primary||Persistent and severe neurological deficit caused by cerebral arterial spasm at the end of 21-day treatment period.|
|Secondary||Severity of spasm as determined by angiogram performed within 48 hours of onset of neurologic deficit.|
