Nozinan

Methotrimeprazin (Levomepromazine) is a phenothiazine derivative with antipsychotic and sedative effects. It primarily acts by blocking dopamine-D2 and serotonin-5-HT2A receptors and additionally possesses antihistaminic and anticholinergic properties. The substance is used in psychiatry for the treatment of psychoses and for sedation; it is also applied in palliative medicine for pain and symptom control. Side effects may include sedation, orthostatic hypotension, and anticholinergic effects.
