Also Known As: Mesoridazine, Serentil
Mesoridazine (Serentil) is a piperidine neuroleptic drug belonging to the class of drugs called phenothiazines, used in the treatment of schizophrenia. It is a metabolite of thioridazine. The name is partially derived from the MEthyl-SulfOxy group in the structure.
It has central antiadrenergic, antidopaminergic, antiserotonergic and weak muscarinic anticholinergic effects.
Serious side effects include akathisia, tardive dyskinesia and the potentially fatal neuroleptic malignant syndrome.
Mesoridazine was withdrawn from the United States market in 2004 due to dangerous side effects, namely irregular heart beat and QT-prolongation of the electrocardiogram.
