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.

Sedatives and Hypnotics: Overview
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...

Sedatives and Hypnotics Drugs: Benzodiazepines
Benzodiazepines work by enhancing the effects of the inhibitory neurotransmitter GABA. They bind to the GABAA receptor, increasing its affinity for GABA, which opens chloride...
Sedatives and Hypnotics Drugs: Miscellaneous Agents
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
