Title

EVALUATION OF THE EFFECTS OF SELEGILINE AND AMANTADINE ON MORPHINE INDUCED TOLERANCE AND DEPENDENCE IN MICE

Pages

  33-38

Abstract

 Objectives: Several studies have indicated that co-administration of N-methyl-D-aspartate (NMDA) receptor antagonists could attenuate the development of MORPHINE induced TOLERANCE and dependence in mice. The aim of this study was to investigate the effects of SELEGILINE (MAO-B inhibitor and NMDA receptor inhibitor) and AMANTADINE (NMDA receptor antagonist and Dopaminergic system activator) or their co administration on TOLERANCE (to analgesic effect) and WITHDRAWAL syndrome in mice. Methods: In different groups of mice MORPHINE (50 mg/kg, ip) or MORPHINE (50 mg/kg, ip) + SELEGILINE (10, 20, 40 mg/kg, ip) or MORPHINE (50 mg/kg, ip) + AMANTADINE (20, 40, 80 mg/kg , ip) or MORPHINE (50 mg/kg, ip) + AMANTADINE (20 mg/kg, ip) + SELEGILINE (10 mg/kg, ip) was administrated once a day for four days. The drugs (selegiline or AMANTADINE) administered 30 minutes before daily administration of MORPHINE (50 mg/kg, ip). TOLERANCE was assessed by administration of MORPHINE (9 mg/kg, ip) and using hot plate test on fifth day. To investigate the WITHDRAWAL symptoms (jumping and standing on feet) in different groups MORPHINE (50 mg/kg, ip) injected for 4 days. In the forth day half hour after the last injection, different doses of SELEGILINE, AMANTADINE or their co-administration were injected and after 1.5 hour later naloxone (5 mg/kg, ip) was injected and immediatly the WITHDRAWAL symptoms were detected during 30 minutes. Results: The results showed that different doses of AMANTADINE, increased the TOLERANCE to analgesic effects of MORPHINE significantly (P<0.001), WITHDRAWAL syndroms in the doses of 40 & 80 decreased significantly (P<0.01). But SELEGILINE (10, 20, 40 mg/kg, ip) did not have a siginificant effect on the inhibition of TOLERANCE and WITHDRAWAL syndromes. Co administration of SELEGILINE and AMANTADINE didn’t decrease the TOLERANCE to MORPHINE in hot plate test significantly. Conclution: It is concluded that, Probably AMANTADINE in this study has a mechanism of activation of dopaminergic system in the administered doses. On the other hand SELEGILINE potentiated adrenergic system with these doses.
