Mechanism of action

Placebo matching formulations are inactive preparations designed to be indistinguishable from the active drug in appearance, taste, and administration to maintain blinding in randomized controlled trials. In this case, it mimics Seroquel IR tablets but contains no active quetiapine ingredient, allowing researchers to isolate the true pharmacological effects of quetiapine from placebo response effects.
