Typical antipsychotic medication From Wikipedia, the free encyclopedia
Pipotiazine (Piportil), also known as pipothiazine, is a typical antipsychotic of the phenothiazine class[2] used in the United Kingdom and other countries for the treatment of schizophrenia.[3] Its properties are similar to those of chlorpromazine. A 2004 systematic review investigated its efficacy for people with schizophrenia:

Although well-conducted and reported randomized trials are still needed to fully inform practice (no trial data exists reporting hospital and services outcomes, quality of life, satisfaction with care and economics) pipotiazine palmitate is a viable choice for both clinician and person with schizophrenia.[4] | ||||||||||||||||||||||||||||||||||||

Pipotiazine palmitate is used to treat schizophrenia.[15]
Pipotiazine palmitate is contraindicated in people with circulatory collapse (shock), altered states of consciousness, including drug intoxication, or other serious health conditions (liver disease, kidney disease, pheochromocytoma, severe cardiovascular disease, or blood dyscrasias). It is contraindicated in people with severe depression. Pipotiazine palmitate should not be used in people who have a history of allergic reactions to any component of the medicine or to chemically similar medicines (phenothiazines).[15]
Pipotiazine was available as a long-acting injectable formulation (pipotiazine palmitate). After deep intramuscular injection, pipotiazine palmitate reaches maximum plasma concentration in 7-14 days, has an elimination half-life of 15 days, and reaches steady-state levels after 2 months of usual dosing (given every 4 weeks).[16]
The alkylation of 2-Dimethylaminosulfonylphenthiazine [1090-78-4] (1) with 1-Bromo-3-chloropropane (2) gives 10-(3-chloropropyl)-N,N-dimethylphenothiazine-2-sulfonamide [40051-12-5] (3). Alkylation with 4-Piperidineethanol [622-26-4] (4) completes the synthesis of Pipothiazine (5).
The long-acting injectable formulation of pipotiazine (pipotiazine palmitate) was withdrawn from all markets globally in March 2015 due to a shortage of the active ingredient.[20]
