Ivermectin for COVID-19
4th treatment shown to reduce risk in August 2020
*, now known with p < 0.00000000001 from 103 studies, recognized in 22 countries.
No treatment is 100% effective. Protocols combine complementary and synergistic treatments. * >10% efficacy in meta analysis with ≥3 clinical studies.
4,200+ studies for 60+ treatments.
Review of ivermectin for COVID-19. Authors note that Kitasato University's project was expanded in response to the results of Caly et al. which had left questions regarding in vivo therapeutic levels, and the results of those studies were positive. Early in the pandemic, Kitasato University requested Merck to conduct clinical trials in Japan because they have priority for an expansion of ivermectin's indications, however Merck declined.
Since large companies have declined to study ivermectin for COVID-19, trials have been mostly doctor-initiated with relatively little funding. Authors discuss these, noting that the physicians involved are enthusiastic about avoiding bias, and strive to treat and prevent COVID-19 witn non-profit motives.
Authors discuss the trials, epidemiological data, and inaccurate statements made by certain authorities.
Authors note that regulations make it challenging for doctor-initiated trials to enroll many participants in a timely manner.
Authors conclude that ivermectin may turn out to be comparable to the benefits achieved from the discovery of penicillin - said to be one of the greatest discoveries of the twentieth century.
Authors include the nobel prize winning biochemist who discovered ivermectin, Satoshi Ōmura

Global trends in clinical studies of ivermectin in COVID-19
Ph.D Morimasa Yagisawa, M.D Patrick J Foster, Ph.D Hideaki Hanaki, Ph.D Satoshi Ōmura
Response to the initial alarm bells of the Coronavirus infection, which occurred in Wuhan City, Hubei Province, China in November 2019, was delayed as it was announced to be a type of pneumonia of unknown cause. The WHO warned about traveling to China in January 2020. After much urging, the world was finally properly warned, but the Chinese government did not accurately announce the outbreak situation. Consequently, the delaying of the construction of an epidemic prevention system worldwide has resulted in the direst infection circumstances facing the world today. One year has passed since the WHO named the new coronavirus SARS-CoV-2 infection, COVID-19, and it was declared a pandemic on the 11 th of March 2020, based on the judgment that it corresponds to "an internationally concerned public health emergency". Suppression of virus transmission by vaccine has finally begun. To date, the pandemic has affected more than 115 million people and killed more than 2.5 million people in 220 countries/ regions around the world. There appears to a potential for control in the near future. However, there is a limit to the supply of vaccines and developed countries are competing to obtain the required amount of vaccination necessary for their own citizens. Although the WHO is trying to secure a certain amount for developing countries, it is predicted that a considerable period of time will be required before COVID-19 becomes controllable. On the other hand, with regard to therapeutic agents for COVID-19, studies began at an early stage. The therapeutic effects of hydroxychloroquine or chloroquine, lopinavir/ritonavir combination, tocilizumab, interferon β1, as well as others, were found to have limited efficacies or no effect. Remdesivir improves recovery time by as much as 30% in critically ill patients, but it is not suitable for mild to moderately ill patients-which comprises the majority of infected individuals. Although the Mar. 2021 THE JAPANESE JOURNAL OF ANTIBIOTICS 74-1 45 ( 45 ) steroid drug dexamethasone is effective in alleviating inflammatory symptoms, its use in mild to moderately ill patients without significant inflammatory symptoms is not recommended. Currently, there are no therapeutic agents available for mildly ill patients who are being treated at home (or in self-isolating accommodations) or for moderately ill hospitalized patients. Nothing is as helpless as a disease without a cure. In a situation where the number of COVID-19 patients is rapidly expanding, the number of deaths increasing worldwide, hydroxychloroquine, doxycycline, azithromycin, and other drugs are ineffective for therapeutic purposes, an effective treatment method is being sought. An Australian research group reported that ivermectin suppresses SARS-CoV-2 replication in an in vitro infection experiment. Ivermectin has been widely used since 1987 for the control of river blindness and lymphatic filariasis, as well as in the treatment of scabies in humans...
