Abstract1. The effect of ondansetron, a selective 5-hydroxytryptamine3 (5-HT3) receptor antagonist, was studied in morphine-addicted rats. Morphine-dependence and tolerance, induced by drinking increasing concentrations of morphine sulphate in 5% sucrose solution for 3 weeks, were demonstrated by the naloxone-precipitated withdrawal syndrome and tail flick response to a thermal noxious stimulus (water at 50 degrees C), respectively. 2. Morphine-dependence, assessed by naloxone precipitated withdrawal, was undetectable by the 6th day, when the animals drank only tap water for 7 days after the 3-week induction period. 3. When detoxified rats were offered sucrose and morphine solutions for 10 days, the recurrence of opiate solution preference with relapse to dependence and tolerance was observed. 4. Giving ondansetron (0.1 or 1 microgram kg-1; i.p.; twice daily) on the 14th day of, or 7 days prior to, the 3-week induction period reduced dependence and tolerance seen during the 3-week morphine induction and the 10-day drinking preference periods. 5. 5-Hydroxytryptamine2 (5-HT2) receptor antagonism by cyproheptadine (100 or 250 micrograms kg-1; i.p.; twice daily) did not influence morphine-dependence and tolerance. 6. These findings suggest that ondansetron may be useful for treating opiate addiction and lowering the recidivism rate.
