thioridazine

n. a low-potency antipsychotic of the piperidine phenothiazine class that, like others of its class, causes sedation and significant anticholinergic effects. Adverse effects unique to thioridazine include the potential to cause retinal changes possibly leading to blindness (retinitis pigmentosa) at doses exceeding 800 mg per day. It can also cause severe disturbances in heart rhythm: Its ability to prolong the Q-T interval may cause fatal arrhythmias (see electrocardiographic effect). It should not be taken by patients who have cardiac arrhythmias or who are taking other drugs that may prolong the Q-T interval. U.S. trade name: Mellaril.
