Effect of nimodipine on blood pressure in acute ischemic stroke in humans

Nimodipine is currently under investigation for the treatment of acute stroke. Although relatively specific for the cerebrovasculature, acute reductions in blood pressure after a dose may adversely affect neurologic outcome. We studied 29 consecutive acute ischemic stroke patients treated with placebo (n = 9) or either 120 (n = 10) or 240 (n = 10) mg/day of nimodipine. Blood pressure was recorded before and 30 and 60 minutes after a dose for the first 8 days. Ten neurologic physicians were asked to predict the treatment group (placebo or drug) of randomly selected patients based on blood pressure results. Only those patients on 240 mg/day of nimodipine had significant decreases in blood pressure after a dose (p less than 0.001); however, these were minimal (average 10 mm Hg systolic). Only 26 of 48 treatment predictions (54%) were correct. At the studied doses, nimodipine has a minimal effect on blood pressure in the acute stroke period.
