How it works
This product’s leaflet is published as a scanned document. This section quotes the US prescribing label for the same active substance (quetiapine fumarate). It describes the substance, not this Bulgarian product — its uses and doses can differ.
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.
