ABSTRACT
AIM To investigate the effects of ondansetron, a selective 5 Hydroxytryptamine3 (5 HT 3) receptor antagonist, on morphine physical dependence. METHODS The morphine dependent models in mice and in isolated Guinea pig ileum were used. RESULTS Pretreatment of ondansetron for 12 days significantly reduced morphine withdrawal symptoms in mice ,such as body weight loss(Groups 2~100 ?g?kg -1 ?d -1 ) or reduced both body weight loss and jumping times (Group 100 ?g?kg -1 ?d -1 ). In addition, concomitant treatment with ondansetron(1~20 ?mol?L -1 ) dose dependently suppressed the contraction induced by naloxone in Guinea pig ileum. CONCLUSION The chronic pretreatment of ondansetron can prevent morphine physical dependence to some extent.
