Qusel XR (150mg) 10 Tablets

Quetiapine, the active ingredient in Quetiapine 150mg Tablets, primarily acts as an antagonist at multiple neurotransmitter receptors in the brain. Its mechanism of action involves binding to dopamine receptors, specifically D2 receptors, in the mesolimbic pathway, which helps to regulate emotional and mood-related behaviors. Quetiapine also has a high affinity for serotonin receptors, particularly 5-HT2A receptors, leading to antagonism and contributing to its therapeutic effects. Additionally, it blocks histamine and alpha-adrenergic receptors, which may be responsible for some of its side effects. By modulating these neurotransmitter systems, quetiapine helps restore the balance of certain chemicals in the brain, thereby improving mood, reducing psychotic symptoms, and exerting its antipsychotic and mood-stabilizing properties.
