Ivermectin for COVID-19
4th treatment shown to reduce risk in August 2020
*, now with p < 0.00000000001 from 104 studies, recognized in 22 countries.
No treatment is 100% effective. Protocols combine treatments. * >10% efficacy, ≥3 studies.
4,300+ studies for 75 treatments.
In Silico study reporting that ivermectin had the best affinity towards all targeted proteins and showed efficient binding to non-structural proteins.
68 preclinical studies support the efficacy of ivermectin for COVID-19:
Ivermectin, better known for antiparasitic activity, is a broad spectrum antiviral with activity against many viruses including H7N766, Dengue32,67,68, HIV-168, Simian virus 4069, Zika32,70,71, West Nile71, Yellow Fever72,73, Japanese encephalitis72, Chikungunya73, Semliki Forest virus73, Human papillomavirus52, Epstein-Barr52, BK Polyomavirus74, and Sindbis virus73.
Ivermectin inhibits importin-α/β-dependent nuclear import of viral proteins66,68,69,75, shows spike-ACE2 disruption at 1nM with microfluidic diffusional sizing33, binds to glycan sites on the SARS-CoV-2 spike protein preventing interaction with blood and epithelial cells and inhibiting hemagglutination36,76, shows dose-dependent inhibition of wildtype and omicron variants31, exhibits dose-dependent inhibition of lung injury56,61, may inhibit SARS-CoV-2 via IMPase inhibition32, may inhibit SARS-CoV-2 induced formation of fibrin clots resistant to degradation5, inhibits SARS-CoV-2 3CLpro49, may inhibit SARS-CoV-2 RdRp activity24, may minimize viral myocarditis by inhibiting NF-κB/p65-mediated inflammation in macrophages55, may be beneficial for COVID-19 ARDS by blocking GSDMD and NET formation77, shows protection against inflammation, cytokine storm, and mortality in an LPS mouse model sharing key pathological features of severe COVID-1954,78, may be beneficial in severe COVID-19 by binding IGF1 to inhibit the promotion of inflammation, fibrosis, and cell proliferation that leads to lung damage4, may minimize SARS-CoV-2 induced cardiac damage35,43, increases Bifidobacteria which play a key role in the immune system79, has immunomodulatory46 and anti-inflammatory65,80 properties, and has an extensive and very positive safety profile81.

Highlights 1. Our findings confirm the role of Q163 aminoacid site for potential tethered site or target which is in agreement with ivermectin, the best possible and known drug. 2. We have employed a rigorous strategy in screening the docking complexes from a majority of hypothetical genes or orphan open reading frames, structural and non-structural proteins. 3. We believe that the findings presented in our paper will appeal to researchers working on COVID-19, particularly those interested to characteristically screen docking complexes.
Author contributions: GP, PBK and RP ideated the project. RS and AP jointly analysed the structures and modelled the docking complexes. PS performeddid the protein interaction analyses. AP and RS wrote the first draft with PS, PBK, BM and RP. GP, PBK, PS, VAN and RP proofread the manuscript. Competing interests: None
