چکیده انگلیسی
In this study, the effect of adenosine receptor agents on nicotine induced antinociception, in formalin test, has been investigated. Intraperitoneal (i.p.) administration of different doses of nicotine (0.1, 1, 10 and 100 μg kgâ1) induced a dose-dependent antinociception in mice, in the both first and second phases of the test. Adenosine receptor antagonist, theophylline (5, 10, 20 and 80 mg kgâ1, i.p.) also induced antinociception in the both phases, while a dose of the drug (40 mg kgâ1, i.p.) did not induce any response. Theophylline reduced antinociception induced by nicotine in both phases of formalin test. The A2 receptor agonist, 5â²-N-ethylcarboxamide adenosine (NECA; 1 and 5 μg kgâ1, i.p.) also produced antinociception, which was reversed with different doses of theophylline (5, 10, 20 and 40 mg kgâ1, i.p.). But administration of the adenosine receptor agonist, NECA did not potentiate the response of nicotine. It is concluded that adenosine system may be involved in modulation of antinociception induced by nicotine.
