    Product Description

    Quetiapine is an atypical, second generation antipsychotic compound.1,2,3 It has effects at multiple receptors, antagonizing dopamine D1, D2, and D3 receptors (Kis = 994, 379, and 340 nM, respectively), serotonin 5-HT1A, 5-HT2A, and 5-HT7 receptors (Kis = 394, 118, and 307 nM, respectively), and α1A, α1B, and α2C adrenergic receptors (Kis = 22, 15, and 29 nM, respectively).4,5 Quetiapine also potently antagonizes the histamine H1 receptor (Ki = 11 nM).5

    WARNING This product is not for human or veterinary use.
