Optimizing the Antimicrobial Effects by using Natural Compounds in COVID-19 Management

Abstract

Abstract: COVID-19 has emerged as the most significant global health issue of our time. The causative agent, SARS-CoV-2, causes extensive damage to the lower respiratory tract in susceptible populations, leading to lung damage and death. COVID-19-infected patients are also prone to respiratory pathogens such as Pseudomonas aeruginosa, Staphylococcus aureus, Klebsiella pneumoniae, and E. coli. In some cases, these respiratory pathogens are multidrug-resistant and cause life-threatening infections in patients. Since the existing antibiotics are ineffective against these antibiotic-resistant bacteria, urgent attention is required to develop new and effective therapeutic agents to combat antimicrobial-resistant bacteria. Alternatively, novel therapeutic strategies can be explored to enhance the antimicrobial effects of the existing antimicrobial agents, such as antibiotics. Adding natural compounds with existing antimicrobial agents to increase their antimicrobial activity is one of the most suitable and promising options to combat the rising threat of both COVID-19 and antimicrobial resistance. Natural compounds are generally considered safe and may even reduce the side effects of drugs and medicines. In light of such advantages, the current review summarized some of the studies that have combined natural compounds with antibiotics and antiviral to increase the antimicrobial potential of these drugs. This study can help researchers compare and understand already existing data to design new studies to develop antimicrobial agents against COVID-19.
