Receiving Quetiapine Fumarate prolonged-release tablets treatment for at least 1 month prior to randomization and is on Quetiapine Fumarate prolonged-release tablets EQ 400 mg base once daily dosage at the time of screening. 3. Willing and able to comply with housing, restrictions and other protocol requirements as indicated by signed written informed consent witnessed by a legally acceptable representative. 4. Females of childbearing potential (who has not completed 1 year after menopause & have not gone through hysterectomy or bilateral tubal ligation) must have a negative pregnancy test (at screening, before randomization and before check-in to housing e.g. day 0) as well as must be non-lactating at screening and must agree to use an effective contraceptive method during study.

Exclusion criteria

Exclusion criteria: 1. History of allergic reactions to Quetiapine or other component of the prolonged-release formulation. 2.
