Melatonin, a hormone synthesized in the pineal gland, regulates biological rhythms and offers antioxidant protection. It is therapeutically used for sleep disorders, circadian rhythm issues, and neurodegenerative diseases like Alzheimer's.
Area of Science:
- Endocrinology
- Neuroscience
- Chronobiology
Background:
- Melatonin is a pineal gland hormone secreted nocturnally.
- It influences biological rhythms, sleep, and possesses antioxidant properties.
- Potential roles in preventing cancer and neurodegenerative diseases are recognized.
Purpose of the Study:
- To elucidate the multifaceted roles of melatonin in human physiology.
- To review its therapeutic applications in sleep disorders and circadian rhythm regulation.
- To explore its potential in cancer prevention and neuroprotection.
Main Methods:
- Literature review of melatonin's synthesis, secretion, and physiological effects.
- Analysis of therapeutic uses for sleep, jet lag, and shift work.
- Examination of evidence for melatonin in cancer and neurodegenerative disease management.
Main Results:
- Melatonin regulates circadian rhythms and promotes sleep.
- It exhibits significant antioxidant and potential anti-carcinogenic effects.
- Evidence supports its use in Alzheimer's disease and other neurodegenerative conditions.
Conclusions:
- Melatonin is a key regulator of sleep and circadian rhythms.
- Its antioxidant and protective functions are vital for health.
- Therapeutic applications include sleep disorders, circadian rhythm disorders, and neuroprotection.

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...
