This excerpt links to a long and difficult article from a scientific publication, The Journal of Antibiotics. If you can make it through the article, but you may just want to stop at the abstract or skip to the conclusion. From Asiya Kamber Zaidi and Puya Dehgani-Mobaraki at nature.com:
Considering the urgency of the ongoing COVID-19 pandemic, detection of various new mutant strains and future potential re-emergence of novel coronaviruses, repurposing of approved drugs such as Ivermectin could be worthy of attention. This evidence-based review article aims to discuss the mechanism of action of ivermectin against SARS-CoV-2 and summarizing the available literature over the years. A schematic of the key cellular and biomolecular interactions between Ivermectin, host cell, and SARS-CoV-2 in COVID-19 pathogenesis and prevention of complications have been proposed.
