Metronidazole and Coronavirus

[Guide]

Metronidazole (brand name Flagyl) has been used to treat rosacea for many years, not chiefly for its antibacterial component but more importantly for its anti-inflammatory treatment component. Metronidazole is also classified as an antiprotozoal treatment along with the larger category of anti-parasitic agents. Recently due to the coronavirus pandemic, metronidazole is being investigated to treat coronavirus. A paper published March 30, 2020 online in the Archives of Academic Emergency Medicine concluded, "Metronidazole, owing to its immunopharmacological behavior, plays a pivotal role in several essential biological processes. Based on the reported immunological manifestations of COVID-19 infection, it could serve as a potential candidate to counteract majority of the immunopathological features of the disease. Therefore, clinical trials with a large sample size are necessary to determine its efficacy in the treatment of COVID-19 infection." [1] Virus and rosacea has never, ever been ruled out. Metronidazole is just one treatment for rosacea that is being investigated along with other rosacea treatments.
