The effects of dilazep dihydrochloride on angio-graphic vasospasm and regional cerebral blood flow after subarachnoid hemorrharge were evalu-ated in double hemorrhage canine model. Severe angiographic vasospasm of basilar artery (per-cent reduction of intra-luminal diameter ; 52.4%) was shown in untreated dogs. Daily intra-venous administration of dilazep (O.3 mg/kg for one hour) significantly inhibited angiographic vasospasm (percent reduction of intra-luminal diameter ; 33.2 %, p<0.05). Dilazep had a marked vasodilatory effect even in severe vasospasm in untreated dogs, and had a tendency to increase cerebral blood flow of the cerebral cortex in spite of reduced blood pressure.

From these characteristics of action, intra-venous administration of dilazep would be useful agent for the treatment of cerebral vasospasm after subarachnoid hemorrhage.
