This review explores melatonin, a hormone with anti-inflammatory and neuro-protective effects, for critical care. Evidence suggests potential benefits in sleep, delirium, and sepsis management for intensive care unit patients.
Area of Science:
- Endocrinology
- Critical Care Medicine
- Neuroscience
Background:
- Recent advancements have elucidated the multifaceted roles of melatonin, a hormone known for regulating mitochondrial function, inflammation, oxidative stress, and sleep.
- Melatonin's physiological effects, including anti-inflammatory, antioxidant, and neuroprotective properties, suggest potential applications in clinical medicine, particularly in critical care.
Purpose of the Study:
- To review the physiological basis for using melatonin in the critical care setting.
- To examine the current evidence supporting melatonin's utility in intensive care unit (ICU) patients.
Main Methods:
- Literature review of studies investigating melatonin's physiological roles and therapeutic potential.
- Analysis of research focusing on melatonin's impact on sleep, delirium, and sepsis in critical care.
Main Results:
- Melatonin exhibits properties relevant to critical care, such as immune enhancement and mitochondrial function regulation.
- Emerging evidence supports melatonin's potential role in managing sleep disturbances, delirium, and sepsis within the ICU.
Conclusions:
- Melatonin presents a promising therapeutic avenue for critical care, supported by its diverse physiological actions.
- Further research is warranted to fully establish melatonin's efficacy and optimal use in intensive care settings.

Management of Insomnia
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...
