Objective： To analyze the rationality and standardization of benzodiazepine drugs in chronic insomnia patients. Methods: 148 patients with chronic insomnia from November 2022 to November 2023 were selected, the electronic prescription data were collected, the use of benzodiazepines was observed, and the rationality and standardization of benzodiazepine use were evaluated. Results: 55 of the 148 patients were on benzodiazepines, alprazolam tablets were the most prescribed, for 48 sheets (32.43%), 5 clonazepam tablets (3.38%), 2 diazepam tablets (1.35%). The majority of chronic insomnia patients were prescribed non-benzodiazepines (93, 62.84%). In the non-standard situation of benzodiazepine drugs, the prescription writing is not standardized. Repeated drug use, too long drug use time, inappropriate scope of drug use, incompatibility and other conditions appear less. Drug utilization index (DUI) of alprazolam tablets, clonazepam tablets and diazepam tablets were <1, Drug use is justified. Conclusion: The overall process of benzodiazepine treatment for chronic insomnia patients in our hospital is reasonable and normative, and some deficiencies need to be further improved.
