title: [Effects of 1,5 benzodiazepine beta lactam on sleep].
abstract: Various substances have been used as sleep inductors, but their use has declined, due to their undesirable side effects, and they have been replaced mainly by benzodiazepines. There currently exists a great variety of benzodiazepines with an increasing, clinical use, although they also present certain disadvantages. The effect on sleep of the intraperitoneal administration (0.9 mg/kg) of 7-(p-cl-phenyl)-8-phenoxy-4,5-benzo-3-aza-2-none, was analysed in chronically implanted wistar rats. Results indicate that this substance decreases wakefulness and increases significantly slow-wave and paradoxical sleep. Latency of the first phase of paradoxical sleep show a tendency to increase. It is concluded that this substance has hypnogenic effects.
