Clinical Utilities
Thioridazine (Mellaril) is a phenothiazine used to treat psychotic disorders (e.g., schizophrenia). It is also used to treat patients having multiple mood disorders including depression, anxiety, tension, sleep disturbances, and fears. The antipsychotic activity is thought to be attributable in part to blockage of dopamine receptors in the central nervous system.
