Delayed effect of administration of COX-2 inhibitor in mice with acute cerebral ischemia

Abstract

This study was designed to investigate the time lag of effect of NS398, selective COX-2 inhibitor, on infarct volume and neurologic deficits in mice with experimentally-induced cerebral ischemia. Our results showed that the beneficial effect of NS398 on reduction of infarct volume and improvement of neurologic deficits were noted more than 24 h after the injection regardless of the administration timing.
