To date, over 177.13 million cases have been reported, and over 3.8 million have lost their lives. Finding effective treatments that can mitigate severe disease remains a crucial area of scientific research. Drug repurposing for COVID-19 helps scientists identify potential drugs to treat COVID-19 without going through the rigorous process of formulation, clinical trials, and gaining regulatory body approval. Many of the drugs used for COVID-19 today were initially developed for other pathogens. Early-stage trials from scientists at the University of Pennsylvania,...
