The results of multicenter clinical trials show the broad potential of melatonin since discovery of this adaptogen to the present day. Melatonin is a neuropeptide that is synthesized mainly in the small brain gland, the pineal gland, and has a unique effect in humans and animals. Using melatonin, the pineal gland participates in the organization of circadian periodism and regulation of cyclic processes, acting as an intermediary between the pacemaker mechanism of the suprachiasmatic nuclei (SCN) and peripheral organs. The pineal gland and the SCN of the hypothalamus form part of the system of the so-called biological clock of the body, which plays a key role in the mechanisms of regulation of the biological clock via circadian rhythms and ageing. Initially, melatonin was only considered a hormone involved in the synchronization of the mechanisms of the circadian rhythm, but later it was found that, in addition to this hormonal function, it takes part in the regulation of the seasonal cycle in animals and humans. At present, melatonin drugs have shown high efficacy and safety in various sleep-wake disorders regardless of their genesis, disorganization of circadian rhythms, stress adjustment disorders, rapid change of time zones, shift work and in complex therapy of patients with cerebrovascular diseases. The article considers the multimodal capabilities of melatonin, including adaptogenic, biorhythmogenic, hypnotic, immunostimu-lating, antioxidant effects. The role of melatonin in the treatment of various central nervous system disorders, including neurodegenerative diseases, has been determined. The review emphasizes the wide-ranging effects of melatonin and offers great opportunities for measuring melatonin as a biomarker for early detection and follow-up of various diseases.
