The effects of nicardipine on local cerebral blood flow were also studied in patients with a subacute brain infarction. Results: Mean cerebral blood flow was significantly increased after a single oral administration of nicardipine but not after nifedipine retard. Both calcium antagonists reduced mean arterial pressure. Nifedipine retard acted mainly by reducing blood pressure and nicardipine mainly by reducing cerebrovascular resistension in stoke patients Copyright © 1993 Wolters Kluwer Health, Inc.
