This article summarizes the likely benefits of melatonin in the attenuation of COVID-19 based on its putative
pathogenesis. The recent outbreak of COVID-19 has become a pandemic with tens of thousands of infected
patients. Based on clinical features, pathology, the pathogenesis of acute respiratory disorder induced by either
highly homogenous coronaviruses or other pathogens, the evidence suggests that excessive inflammation, oxidation, and an exaggerated immune response very likely contribute to COVID-19 pathology. This leads to a
cytokine storm and subsequent progression to acute lung injury (ALI)/acute respiratory distress syndrome
(ARDS) and often death. Melatonin, a well-known anti-inflammatory and anti-oxidative molecule, is protective
against ALI/ARDS caused by viral and other pathogens. Melatonin is effective in critical care patients by reducing vessel permeability, anxiety, sedation use, and improving sleeping quality, which might also be beneficial
for better clinical outcomes for COVID-19 patients. Notably, melatonin has a high safety profile. There is significant data showing that melatonin limits virus-related diseases and would also likely be beneficial in COVID19 patients. Additional experiments and clinical studies are required to confirm this speculation.
