The purpose of this study is to determine how safe and effective Seroquel (quetiapine
fumarate) is compared to placebo (a non-drug tablet) for a period of up to 10 weeks in the
treatment of agitation symptoms in nursing home or assisted care residents.
PLEASE NOTE: Seroquel SR and Seroquel XR refer to the same formulation. The SR designation
was changed to XR after consultation with FDA.
