In this study, the influences of nicotinic receptor agents on baclofen-induced antinociception in the tail-flick test have been studied. Intraperitoneal administration of baclofen (2.5, 5 and 10 mg/kg) to mice induced a dose-dependent antinociception in the tail-flick test. Subcutaneous injection of nicotine (0.5-2.5 mg/kg) also caused a dose-dependent antinociceptive response. Intracerebral (10 and 20 microg/mouse) but not intraperitoneal administration of hexamethonium (5 and 10 mg/kg) to mice decreased the response of both nicotine and baclofen. However, administration of the GABA(B) antagonist CGP 35348 (100 and 200 mg/kg) decreased the response induced by baclofen but not by nicotine. It is concluded that at least part of the baclofen-induced antinociception may be mediated through a nicotinic mechanism.
