The World Health Organization has added two more drugs to its guidelines for recommended treatments for COVID-19, as the more infectious Omicron variant of the coronavirus triggers an unprecedented surge in cases around the world. The drug baricitinib used to treat rheumatoid arthritis is strongly recommended for patients with severe or critical COVID-19, in combination with corticosteroids, The UN agency’s panel of international experts said the drug reduces the need for ventilation and had been found to improve patients’ chances of survival with no sign of an increase in adverse reactions. The panel also gave a conditional recommendation for sotrovimab, an experimental monoclonal antibody treatment, for those with non-severe COVID-19 but at the very highest risk of hospital admission.
