<unk>  (INN, BAN, USAN), also known as methotrimeprazine (common use in America; sold as Nosinan, Nozinan, Levoprome) is an phenothiazine neuroleptic drug. It is a low-potency antipsychotic (approximately half as potent as chlorpromazine) with strong analgesic, hypnotic and antiemetic properties that is primarily used in palliative care.
Serious side effects include tardive dyskinesia, akathisia, abnormalities in the electrical cycle of the heart, low blood pressure and the potentially fatal neuroleptic malignant syndrome.
As is typical of phenothiazine antipsychotics,<unk>  is a "dirty drug", that is, it exerts its effects by blocking a variety of receptors, including adrenergic receptors, dopamine receptors, histamine receptors, muscarinic acetylcholine receptors and serotonin receptors.
