What are the classification and clinical application of antipsychotics?
Antipsychotic drugs are generally divided into three categories: chlorpromazine stands for antipsychotic drugs, imipramine stands for antidepressants, and lithium carbonate stands for mania. Clinical application of antipsychotics: 1

Treat mental illness

Chlorpromazine can be used to quickly control symptoms such as excitement, irritability, aggression and mania in schizophrenia and other mental diseases, reduce and eliminate fantasies and delusions, improve thinking and emotional disorders, and make patients' thinking, emotions and behaviors tend to be consistent. However, the curative effect on negative symptoms such as loneliness and indifference of schizophrenia is poor. The daily dose of chlorpromazine is 30-75 mg, which is taken orally 2-4 times. 2

Antiemesis

It can be used for vomiting caused by uremia, tumor radiotherapy, pregnancy and gastrointestinal diseases, but it is ineffective for vomiting caused by exercise. three

Administration before anesthesia and artificial hibernation

Giving chlorpromazine before anesthesia can calm patients, eliminate tension and anxiety, thus reducing the dosage of general anesthesia and preventing vomiting. The clinical application of antidepressants is to treat depression, enuresis, phobia and chronic pain caused by various reasons. Medication before going to bed can promote sleep and reduce daytime sleepiness and adverse reactions. The initial dose is small, and the dose is gradually increased according to the patient's curative effect and drug tolerance. Clinical application of lithium carbonate is the first choice to treat manic depression, and it can also be used to prevent recurrence. The effect of lithium carbonate is relatively slow, and it takes 2-3 weeks to take effect.
