Interventions

quetiapine fumaratedrug

At baseline, subjects in the experimental group will initially be administered 50 mg/day of Seroquel XR™ (extended release formulation of quetiapine fumarate), to be titrated up to 400 mg/day of Seroquel XR™ by the end of the second week. By the end of week 2, subjects will be stabilized on a dose of 400 mg/day or alternatively 300, 200, 100, or 50 mg/day of study drug, as tolerated. If a subject is unable to tolerate the 50 mg/day dose, he or she will be discontinued from the drug portion of the study.
