A proposed mechanism for the possible therapeutic potential of Metformin in COVID-19

The whole world is facing a tough time these days struggling against the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). There is not any specific effective drug for this viral infection. Thus, we are trying to treat patients with non-specific drug cocktails. Metformin, as a strong base, a potential regulator of Vacuolar ATPase (V-ATPase) and endosomal Na+/H+ exchangers (eNHEs), additionally a regenerative agent for lung fibrosis, seems to be beneficial for patients in acute, chronic and recovery phases of COVID-19.
