The 5-HT3 receptor antagonists, ICS205-930, granisetron and zacopride, at low doses, inhibited the hyperactivity caused by a 13 day mesolimbic dopamine infusion in the rat. The antagonism decreased with the use of higher doses of the 5-HT3 receptor antagonists. The ability of low doses of the 5-HT3 receptor antagonists to inhibit dopamine-induced behavioural changes is similar to the inhibitory profile of known antipsychotic agents. It is suggested that 5-HT3 receptor antagonists may represent a new class of atypical antipsychotic agents.

D004298	Dopamine	One of the catecholamine NEUROTRANSMITTERS in the brain. It is derived from TYROSINE and is the precursor to NOREPINEPHRINE and EPINEPHRINE. Dopamine is a major transmitter in the extrapyramidal system of the brain, and important in regulating movement. A family of receptors (RECEPTORS, DOPAMINE) mediate its action.
