PHARMACOLOGICAL EFFECTS OF MELATONIN AND ITS POTENTIAL APPLICATION IN THERAPY OF GOUT AND ASSOCIATED DISEASES

Introduction. The disturbance in biosynthetic activity of pinealocytes of the pineal gland and subsequent melatonin deficiency in the body are linked to the progression of certain chronic diseases. This has prompted research into correcting chrono-biological dysfunctions, particularly in conditions such as gout and its comorbidities. This study aims to analyze the potential use of melatonin in correcting metabolic disorders in gout and to justify its use as a pharmacotherapeutic agent for treating metabolic and cardiovascular diseases. Materials and methods. We conducted a comprehensive analysis of modern scientific literature from specialized domestic and foreign sources. Emphasis was placed on studies exploring the pharmacological and pharmacotherapeutic aspects of melatonin use in both experimental and clinical settings, particularly those conducted in the last 5-6 years. Results. The research data revealed three main aspects of the problem that must be addressed to understand the experimental, biological, pharmacological, and pharmacotherapeutic foundations for the long-term use of melatonin in clinical practice. The first part of the review highlighted the significant impact of melatonin homeostasis disruption on the pathogenesis of gout and its progression in comorbidity with other conditions such as hypertension, obesity, insulin resistance, metabolic syndrome, and type 2 diabetes. The role of chronobiological disorders and desynchronosis in the progression of these diseases was also established. Pharmacological studies demonstrated the pivotal role of melatonin, as an important factor in neuroendocrine regulation, in organizing the circadian rhythm of the body's vital functions under normal and pathological conditions. Melatonin was found to normalize the pathological processes underlying gout development and comorbid diseases, providing a scientific basis for its use in the treatment of gout, cardiovascular diseases, disturbed metabolic processes, and normalization of circadian rhythms in patients with these conditions. Conclusions. This paper presents data on the causes of gout development and progression, as well as some comorbid diseases, from the perspective of chronobiological disruptions in the body's functions. The review sections delve into the pharmacological and pharmacotherapeutic aspects of melatonin's therapeutic action. The findings confirm the importance of melatonin in effectively treating gout and other comorbid diseases and metabolic disorders.
