title: Selectivity of cerebral vasodilators on basilar arteries.
abstract: Ca-antagonistic activities of cerebral vasodilators, nicardipine and 1-(3,4-dimethoxyphenyl)-2-(4-diphenylmethylpiperazinyl)ethanol dihydrochloride (NC-1100) were tested on basilar and renal arteries, thoracic aorta and portal vein of rabbit, and rat vas deferens. Both the cerebral vasodilators used herein had a selectivity to basilar arteries. The selectivity to the basilar arteries is considered to be one of the factors in deciding the pharmacological property of the cerebral vasodilators.
