Cerebrovascular autoregulation is resistant to calcium channel blockade with nimodipine.

Abstract

In normal baboons cerebrovascular resistance changed along with blood pressure to maintain blood flow constant. This 'autoregulation' was not significantly altered in animals treated with a dose of the calcium channel blocker nimodipine causing selective cerebral vasodilation.
