Haloperidol is a medication used primarily to treat schizophrenia and other psychiatric disorders. It belongs to a class of drugs called typical antipsychotics. There are several synonyms for haloperidol, including Haldol, Serenace, Aloperidin, Bioperidolo, and Halosten. Each of these names refers to the same drug and contains the same active ingredients. Haloperidol is typically prescribed as a tablet or injection and is most commonly used to alleviate symptoms such as hallucinations and delusions. It works by affecting the chemical balance in the brain, reducing the activity of dopamine, a neurotransmitter associated with positive symptoms of schizophrenia.
