Qpen Sr 100mg Tab (Quetiapine) is an atypical antipsychotic that works by blocking dopamine and serotonin receptors in the brain. This helps to reduce the positive symptoms of schizophrenia (such as hallucinations and delusions) and improve mood and reduce mania in bipolar disorder. The precise mechanism for its effect on depression and irritability remains less fully understood but is thought to involve multiple neurotransmitter systems.
