1 ICS 205-930, a selective and potent 5-HT3 receptor antagonist applied either systemically, or locally into the ventral tegmental area, antagonized the stimulation of dopamine release in the nucleus accumbens, induced by the subcutaneous administration of morphine. Dopamine 5-hydroxytryptamine receptor 3A Rattus norvegicus
2 Since stimulation of dopamine release in the nucleus accumbens is a prerequisite for the expression of the rewarding properties of morphine, its suppression by ICS 205-930 suggests a possible application of 5-HT3 receptor antagonists in the treatment of addiction. Dopamine 5-hydroxytryptamine receptor 3A Rattus norvegicus
