Chlorpromazine, commonly known by the brand name Thorazine, is an antipsychotic medication used to treat various mental health conditions. It's effective in managing symptoms of schizophrenia, bipolar disorder, and severe agitation. Chlorpromazine works by altering the balance of certain chemicals in the brain, helping to alleviate hallucinations, delusions, and disorganized thinking. It's typically administered orally or by injection and may cause side effects such as drowsiness, dizziness, and dry mouth. Regular monitoring is essential to ensure its effectiveness and minimize adverse effects.
