Antipsychotic drugs refer to a class of drugs mainly used to treat schizophrenia, manic episodes and other serious mental disorders, and are mainly divided into traditional antipsychotic drugs and new antipsychotic drugs. Traditional antipsychotic drugs are often used such as sulpiride, fenadine, haloperidol, etc. The main side effects of traditional antipsychotic drugs are extrapyramidal side effects. Patients may exhibit eye muscle spasms, appearing as eye up-turning, neck muscle spasms appearing as slanting neck, and may also appear to be more irritable, unable to sit, and walking around. Some patients may also have such involuntary movements of the mouth and lips, such as chewing movements. Another common side effect is anticholinergic side effects, where patients may experience dry mouth, constipation, blurred vision, etc. A common side effect is elevated prolactin, and female patients may experience menstrual disorders, and male patients may have nipple discharge. Other patients may experience central nervous system side effects, such as dizziness, headache, insomnia, and possibly drowsiness. Newer antipsychotic drugs commonly used include olanzapine, quetiapine, risperidone, aripiprazole, etc. The side effects of this class of drugs are relatively minor, mainly because they may cause metabolic syndrome, that is, they may cause weight gain in patients, and they may cause increased blood sugar and blood lipids, etc.
