[The behavioral characteristics of young and sexually mature animals administered fenazepam, gidazepam and medazepam].

Behavioral methods were used to examine the features of effects of fenazepam. gidazepam, and medazepam in young and mature non-inbred albino male rats. There were age- [correction of sex-]specific differences in responses to a drug. The higher effects the drug possesses, the greater differences there are in its effects on animals of different ages. It is suggested that different maturities of benzodiazepine receptors can affect the behavior of rats of different ages in the proposed tests.
