Pipotiazine
Pipotiazine has actions similar to those of other phenothiazines. Among the different phenothiazine derivatives, it appears to be less sedating and to have a weak propensity for causing hypotension or potentiating the effects of CNS depressants and anesthetics. However, it produces a high incidence of extra pyramidal reactions. It is used for the maintenance treatment of chronic non-agitated schizophrenic patients. Symptoms of overdose include severe extrapyramidal manifestations, hypotension, lethargy and sedation.
