Amisulpride injection is used to prevent and treat nausea and vomiting that may occur after surgery. Amisulpride is in a class of medications called dopamine receptor antagonists. It works by blocking the action of dopamine, a natural substance that may cause nausea and vomiting.

Amisulpride comes as a solution (liquid) to be injected intravenously (into a vein) by a healthcare provider in a hospital or clinic. It is usually given as a single injection just before surgery or as a single dose as soon as nausea or vomiting occurs after surgery.
