The FDA has required a new warning in the label for the scopolamine transdermal patch (Transderm-Scōp, and generics) about a risk of serious or fatal hyperthermia. Scopolamine, an anticholinergic drug, is FDA-approved for prevention of nausea and vomiting associated with motion sickness or recovery after surgery in adults; it is often used off-label to reduce drooling in children and adolescents with neurologic disorders.

The FDA has approved Gimoti (Evoke), a nasal spray formulation of the dopamine-2 (D₂) receptor antagonist metoclopramide, for relief of symptoms in adults with acute and recurrent diabetic gastroparesis. Metoclopramide (Reglan, and generics) has been available for years in conventional and orally-disintegrating tablets and in an injectable formulation. It is the only drug that is FDA-approved for treatment of diabetic gastroparesis.

The FDA has approved IV amisulpride (Barhemsys – Acacia), a selective dopamine-2 and -3 (D₂/D₃) receptor antagonist, for prevention and treatment of postoperative nausea and vomiting (PONV) in adults. It is the first antiemetic to be approved for rescue treatment of PONV in patients who have symptoms despite receiving antiemetic prophylaxis. Oral formulations of amisulpride are available in Europe for treatment of schizophrenia and acute psychotic episodes.
