Quetiapine is an atypical antipsychotic used to manage schizophrenia, bipolar disorder, and depression. It acts by blocking dopamine and serotonin receptors, helping to reduce hallucinations, mood swings, and other psychiatric symptoms. Available in both immediate- and extended-release forms, it is generally well tolerated but may cause sedation, weight gain, or metabolic side effects. Regular monitoring of blood sugar, lipid levels, and blood pressure is recommended during long-term use. Dose adjustments may be needed in elderly patients or those with liver impairment.
