Application of Antioxidants in Curing Respiratory and Pulmonary Disorders

Abstract

Since a couple of decades, respiratory ailments have emerged as a significant public health issue. Numerous primitive civilizations acknowledged the need to relieve the inflamed airways and nasal passages oxidants are a persistent danger to the lungs since they can be produced either intracellularly by metabolic processes (such as mitochondrial electron transfer during respiration or during phagocyte activation) or from another source such as tobacco smoking or air pollutants. It is likely to be advantageous to target oxidative stress with antioxidants or increase endogenous antioxidant levels in the treatment of COPD, asthma, and COVID-19. In trials on both human beings and animals, the administration of small antioxidants via the intratracheal, oral, and vascular routes exhibited only minimal therapeutic potential against short- and long-term oxidative stress. Lipids, proteins, and nucleic acids all respond to oxygen in quick and practical ways. For the ROS (reactive oxygen species) system to run properly, it requires adequate oxidation-reducing components, like vitamins and antioxidants intake. Numerous nutrients, including vitamins such as vitamin A, vitamin B etc., minerals (magnesium, zinc, and iron), flavonoids, and fatty acids, have prominent functions in reducing the likelihood of viral diseases and chronic lung disorders. In this review, the applications of antioxidants in the prevention of respiratory diseases are discussed along with some reported nutraceuticals being used in respiratory disease and patents. The applications of antioxidants in preventing and managing respiratory diseases are discussed in this review, shedding light on the importance of ongoing research in this field. Nutraceuticals, which combine the benefits of nutrition and pharmaceuticals, are also explored as potential solutions for respiratory health.
