The effects of CBD, a potent analgesic cannabinoid on LTB 4 and TXB 2 production stimulated by A23187 was determined in mouse blood ex vivo and in human polymorphonuclear cells in vitro . At a dose of 10 mg/kg administered orally CBD inhibited LTB 4 production in mouse blood and was equieffective to the dual lipoxygenase/cyclo‐oxygenase inhibitor BW755C and the lipoxygenase inhibitor BWA4C used at a dose of 50 mg/kg. In the same blood samples CBD stimulated TXB 2 production from between 20 to 30% over a 4 h period. A23187 stimulation of LTB 4 synthesis in human polymorphonuclear cells was inhibited by CBD and Δ'‐THC in a dose related manner (IC 50 5.4 and 8.2 μm respectively). However, only CBD produced a 100% inhibition of LTB 4 synthesis. The production of TXB 2 in these cells was initially stimulated at low doses by CBD but at higher doses TXB 2 synthesis was inhibited.
