Effects of CB1 receptor antagonist on CBD-induced pentobarbital potentiation in mice. Mice were pretreated with 2 or 5 mg/kg SR141716A by i.v. injection 10 min before CBD administration (10 mg/kg, i.v.) and then administered pentobarbital at 40 mg/kg by i.p. injection. Sleeping time was expressed as the mean % of control (Veh + Veh + pentobarbital) sleeping time (n = 8). Control sleeping time was 35 ± 3 min. Significant difference from control group (**p < 0.01)
