Benzodiazepines (BZDs) alter sleep architecture by increasing stage 2 Non-Rapid Eye Movement (NREM) sleep while decreasing deep NREM sleep and Rapid Eye Movement (REM) sleep. Careful prescription and monitoring are advised due to potential side effects.
Area of Science:
- Sleep Medicine
- Neuroscience
- Pharmacology
Background:
- Insomnia is a prevalent sleep disorder impacting sleep initiation and maintenance.
- Benzodiazepines (BZDs) are frequently prescribed for insomnia treatment.
- Human sleep comprises Non-Rapid Eye Movement (NREM) and Rapid Eye Movement (REM) phases, forming the sleep architecture.
Approach:
- Systematic review of human clinical trials.
- Searched PubMed, BVS, and Google Scholar databases.
- Included studies in English, Portuguese, and Spanish focusing on BZDs and sleep architecture.
Key Points:
- BZDs increase stage 2 NREM sleep.
- BZDs decrease stages 3 and 4 NREM sleep.
- BZDs reduce REM sleep duration.
Conclusions:
- Altered sleep architecture may affect concentration, working memory, and weight.
- Increased stage 2 NREM sleep can subjectively improve sleep quality by reducing awakenings.
- Judicious BZD prescription and close patient monitoring for long-term effects are crucial.

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...
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...
