Key result
Melatonin exerts protective effects against various lung injuries, including acute lung injury, asthma, and COPD, primarily through its antioxidant and anti-inflammatory properties.
Why the study?
Recent studies postulated that melatonin plays critical roles in apoptosis, ischemia-reperfusion injury, and cellular proliferation, prompting a review of its protective molecular mechanisms against various lung injuries.
Melatonin exhibits potential therapeutic benefits in protecting against various lung injuries via anti-inflammatory and antioxidant mechanisms.

Does not support clinical use in lung injury; leaves open confirmation of efficacy in prospective trials.
Melatonin (MT; N-acetyl-5-methoxy-tryptamine), which has multiple effects and roles, is secreted from the pineal gland at night according to the daily rhythm. In addition to circadian regulation, MT has anti-inflammatory, antioxidant and anticancer functions. Recent studies postulated that MT serves a critical role in apoptosis, anti-ischemic reperfusion injury and anti-proliferative effects on various cells. The current review reported on the underlying mechanism behind the protective effect of MT on lung diseases, such as acute lung injury, acute respiratory distress syndrome, chronic obstructive pulmonary disease, lung ischemia-reperfusion injury, sepsis-induced lung injury and ventilator-induced lung injury. MT is considered an adjuvant with therapeutic drugs for preventing inflammation and is responsible for regulating patient sleep cycles in the intensive care unit. The current review described the anti-inflammatory and antioxidant efficiency of MT with a focus on the molecular mechanisms of action in various lung injuries.
