How it works
From the US prescribing label for the same active substance (Quetiapine fumarate). It describes the substance, not this exact product.
The mechanism of action of quetiapine in the listed indications is unclear.
However, the efficacy of quetiapine in these indications could be mediated through a combination of dopamine type 2 (D 2 ) and serotonin type 2 (5HT 2 ) antagonism.
Quetiapine is unlikely to interfere with the metabolism of drugs metabolized by cytochrome P450 enzymes.
The bioavailability of quetiapine is marginally affected by administration with food, with C max and AUC values increased by 25% and 15%, respectively.
