Antipsychotics, also known as strong tranquilizers or neuroleptics, refer to a group of drugs used to treat schizophrenia, bipolar disorder, and other severe mental illnesses. These drugs work by regulating the levels of neurotransmitters in the brain, specifically dopamine and serotonin. Commonly used antipsychotics are phenothiazines and butyrophenones, such as chlorpromazine, thioridazine, perphenazine, trifluoperazine, haloperidol, etc. It should be noted that antipsychotic drugs may cause certain side effects, such as sedation, weight gain, extrapyramidal symptoms, and metabolic disorders.
