amisulpride + dexamethasone

This drug is a **combination of amisulpride and dexamethasone**. Amisulpride is a *selective dopamine D2 and D3 receptor antagonist*, primarily classified as an atypical antipsychotic, also used intravenously as an antiemetic for the prevention and treatment of postoperative nausea and vomiting (PONV) in adults. Its mechanism is based on preferential antagonism of D2 and D3 receptors, targeting symptoms of schizophrenia and preventing nausea/vomiting by blocking dopamine signaling in the chemoreceptor trigger zone. Dexamethasone is a *synthetic glucocorticoid corticosteroid* with potent anti-inflammatory and immunosuppressant properties, often used for its antiemetic effects in surgical and chemotherapy settings. Clinically, the combination is used for multimodal antiemetic prophylaxis in high-risk patients undergoing surgery under general anesthesia, leveraging their distinct mechanisms to provide enhanced prevention of PONV[2][3].
