Qusel XR 200mg is an extended-release formulation of Quetiapine, an atypical antipsychotic used to treat various mental health conditions, including schizophrenia, bipolar disorder, and major depressive disorder (MDD). This medication works by balancing neurotransmitters in the brain, such as dopamine and serotonin, to help manage mood swings, reduce hallucinations, and improve overall cognitive function. Designed for once-daily dosing, Qusel XR provides consistent symptom relief with gradual and prolonged drug release, minimizing fluctuations in blood levels and enhancing treatment efficacy while reducing side effects.
