Labetalol, an alpha- and beta- adrenoceptor antagonist was investigated for its central nervous system effects in rats and mice. A marked reduction in the spontaneous motor activity with no concomittant muscle weakness was produced. The drug caused closure of eyelids in rats. Labetalol caused hypothermia and prolonged the pentobarbitone-induced hyposis. In animals trained for conditioned avoidance response the drug blocked the SCR in all the animals and CAR in a few number of animals. The drug did not protect the animals against electroshock convulsions. From the results it appears that labetalol is a central nervous system depressant.

Rats pretreated daily with delta9-tetrahydrocannabinol (delta9-THC, 8 mg/kg) during 14 days showed tolerance to THC-induced hypothermia and depression of CAR acquisition in a shuttle-box. The noncontingent exposure of THC also produced tolerance to spontaneous (unlearned) behaviors as measured in a open-field test. The data suggest no essential role for learned tolerance in the sense that animals have to to learn to perform under the influence of THC for several of these behaviors.
