One of pathways proposed to facilitate cannabinoid action is the arachidonic acid cascade. Previously, we have shown that prostaglandin attenuated the expression of withdrawal signs in tetrahydrocannabinol-dependent mice. It follows that the cascade might participate in the expression of cannabinoid withdrawal. We utilized a quasi abstinence approach (the induction of a state of cannabinoid withdrawal without giving any cannabinoid substances in a naïve animal) to describe the relationship between the change in prostaglandin level, an end product of the arachidonic acid cascade, and the expression of cannabinoid withdrawal. Administration of 10 mg/kg diclofenac, a prostaglandin synthesis inhibitor, i.p. 30 min before SR 141716A induced cannabinoid withdrawal signs in naïve mice, which were comparable to the true abstinence in cannabinoid-tolerant mice. In turn, 10 mg/kg Δ8-THC i.p., given 15 min prior to SR 141716A, blocked the expression of these signs. These results suggested that the decrease in prostaglandin level is a prerequisite for the expression of cannabinoid withdrawal. © 2005 Elsevier B.V.
