Final answer:
Mesoridazine, Pericyazine, and Pipotiazine are the drugs from the question that belong to the Piperidine class, while 'THIOrdiazine' appears to be a typo and not a recognized drug name in this class.
Step-by-step explanation:
The drugs that belong to the Piperidine class are Mesoridazine, Pericyazine, and Pipotiazine. The fourth drug listed, THIOrdiazine, seems to be a typographical error as there is no known drug by that specific name. Perhaps it is intended to be another phenothiazine derivative which shares a similar naming structure, but it does not belong to the Piperidine class.
Piperidine antipsychotics are part of the larger group of phenothiazines, which have been widely used for the treatment of psychiatric disorders. Phenothiazines also exhibit antiemetic, antinausea, and antihistaminic effects, and can potentiate the effects of analgesics, sedatives, and general anesthetics. Mesoridazine, Pericyazine, and Pipotiazine are examples of drugs within this subclass that have been used for their antipsychotic properties.
