Much information concerning the mechanisms of cell respiration has been obtained through the use of narcotics, such as the barbiturates, urethane and chloretone. These substances in general inhibit respiratory processes and show a certain selectivity of action (cf. Quastel, '39). Recently a new ser

β¦ Synopsis
Flunarizine was tested using a single dose (40 mglkg IP) and multiple doses (30 mg/kg PO presurgery) in 200-250 g male Wistar rats, using physiological measures related to the rapid ionic shift seen in cerebral cortex following a sudden insult. The threshold for initiation of a spreading depression was increased by flunarizine treatment only in rats in which the cortex had previously been injured. The time to rapid ionic shift after cardiac arrest (global ischemia) was increased by both flunarizine and phenytoin. Other measures tested showed no difference in normal cortex under flunarizine treatment. Flunarizine appears to have little or no effect on normal cortical tissure, but rather seems to exert a therapeutic effect on injured cortical tissue. Flunarizine may be a useful agent in the management of cerebral trauma.
