Japanese pharmacist announces that ivermectin shows “antiviral effect” against Omicron January 31, 2022 by Jessa Martin Box with ivermectin, one of the drugs used in the so-called “early treatment” of Covid-.| Photo: Arquivo/Gazeta do Povo The Japanese pharmaceutical company Kowa announced this Monday (31) that the drug ivermectin showed an “antiviral effect” against the Omicron variant of the coronavirus in joint non-clinical research. The group, which is working in partnership with Kitasato University – a medical university in Tokyo -, did not provide further details. The news about the possible effectiveness of ivermectin in the treatment of Covid-19 was initially released by the international agency Reuters which, in a few minutes, changed the title and the original text, removing the reference to the term “efficacy” of the drug in phase three clinical trials. The change is indicated in the text, which states that clinical trials are, in fact, ongoing. For now, the drug is not approved for the treatment of Covid-660 in Japan. In the United States, the FDA has also issued warnings against its use.
