[Benzodiazepines:objective evaluation and rational use].

Benzodiazepines have been on the market for more than half a century and are widely used in clinical practice. Their use in many countries has been limited in recent decades due to drug dependence and dose tolerance in some patients. Currently, benzodiazepines are still effective in treating many mental disorders, but some patients and doctors refuse to use them for fear of drug dependence and dementia caused by long-term use. The author suggests that benzodiazepines should be objectively evaluatedand rationally used.
