Ivermectin (IVM), an approved anthelminthic drug, has been reported to have antiviral, antibacterial, and anticancer activities. Antiviral activity is due to the inhibition of nuclear cargo importin (IMP) protein. The anti-SARS CoV-2 activity through in vitro study was first reported by an Australian team. Later, many studies were conducted, and most of the study results were available as non-peer-reviewed preprints. In this narrative review, literature on the clinical studies conducted with ivermectin from published articles, preprints, and unpublished evidence was collected until 13th June 2021. They are discussed based on the severity of COVID-19 disease. Out of the 23 peer-reviewed published articles, 13 studies were randomized controlled trials. The remaining were either prospective interventional, prospective observational, retrospective cohort, cross-sectional, or case series type of studies; additionally, there were 10 randomized controlled trials available as preprints. In most studies, ivermectin was used in combination with doxycycline, azithromycin, or other drugs. Some studies suggested that a higher dose or increased duration of ivermectin usage was required to achieve favorable effects. In this review, articles on the prophylactic role of ivermectin in COVID-19 are also discussed - wherein the results are more promising. Despite accumulating evidence suggesting the possible use of ivermectin, the final call to incorporate ivermectin in the management of COVID-19 is still inconclusive., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)
