When a group such as the University of Tokyo conducted an experiment using cultured cells on the effect of a therapeutic drug on the Omicron strain of the new coronavirus, it is said that the antiviral drug currently in use had the same effect as on the Delta strain. We announced the research results.

This research was published in the American medical journal "New England Journal of Medicine" by a group of Professor Yoshihiro Kawaoka of the Institute of Medical Science, University of Tokyo.

The group infected cultured cells with the Omicron strain of virus, administered various therapeutic agents to them, and investigated the reaction.

As a result, the two drugs, "remdesivir" and "lagebrio" = generic name "molnupiravir", which are approved in Japan as antiviral drugs for the new corona, both have the effect of suppressing the growth of the virus against the delta strain. It was at the same level as.

Regarding the therapeutic drug using antibody, "Sotrovimab" had a one-fourteenth reduction in response to the conventional virus, but the required effect was maintained, but the Ministry of Health, Labor and Welfare recommended its use for Omicron strains. It is said that the effect of "Ronapreve", an antibody cocktail therapy that is not supposed to be used, could hardly be confirmed.

Professor Kawaoka “Reference for treatment in clinical practice”

Professor Kawaoka said, "Since the Omicron strain has many mutations, it is important to study the effectiveness of drugs used in clinical practice. I would like it to be used as a reference for treatment in clinical practice." ..
