Drug information of Amisulpride


Drug group:

Amisulpride is an antipsychotic drug.  Amisulpride is a selective dopamine antagonist.

Mechanism of effect

Amisulpride binds selectively to dopamine D(2) and D(3) receptors in the limbic system. Low doses of amisulpride preferentially block presynaptic D(2)/D(3)-dopamine autoreceptors, thereby enhancing dopaminergic transmission, whereas higher doses block postsynaptic receptors, thus inhibiting dopaminergic hyperactivity. It may also have 5-ht7 antagonistic effect, useful in depression treatment.
