Tocilizumab, sold under the brand name Actemra among others, is an immunosuppressive drug, used for the treatment of rheumatoid arthritis, systemic juvenile idiopathic arthritis, polyarticular juvenile idiopathic arthritis, giant cell arteritis, cytokine release syndrome, COVID‑19, and systemic sclerosis-associated interstitial lung disease (SSc-ILD).
The drug appeared to shorten the recovery time of 11 COVID-19 symptoms in olgotrelvir-treated patients by 2.4 days on average compared to patients in the placebo group. The drug was also shown to reduce the viral load at day 4 in treated patients compared to the placebo group.
[9] [10] These drugs had been further developed prior to the COVID-19 pandemic for other diseases including SARS. [11] The utility of targeting the 3CL protease in a real world setting was first demonstrated in 2018 when GC376 (a prodrug of GC373) was used to treat the previously 100% lethal cat coronavirus disease, feline infectious ...
It is used to treat COVID‑19 in those infected by SARS-CoV-2. [7] It is taken by mouth. [7] Molnupiravir is a prodrug of the synthetic nucleoside derivative N 4-hydroxycytidine and exerts its antiviral action by introducing copying errors during viral RNA replication. [13] [14]
No participants had received a COVID‑19 vaccine or been previously infected with COVID‑19. [12] The main outcome measured in the trial was the proportion of people who were hospitalized due to COVID‑19 or died due to any cause during 28 days of follow-up. [12] EPIC-HR started in July 2021, and completed in December 2021. [51]
This registry based, multi-center, multi-country data provide provisional support for the use of ECMO for COVID-19 associated acute hypoxemic respiratory failure. Given that this is a complex technology that can be resource intense, guidelines exist for the use of ECMO during the COVID-19 pandemic. [85] [86] [87]
In May 2021, the U.S. Food and Drug Administration (FDA) issued an emergency use authorization (EUA) for sotrovimab for the treatment of mild-to-moderate COVID-19 in people aged twelve years and above weighing at least 40 kilograms (88 lb) with positive results of direct SARS-CoV-2 viral testing and who are at high risk for progression to ...
The Enzyme Commission refers to this family as SARS coronavirus main proteinase (M pro; EC 3.4.22.69). The 3CL protease corresponds to coronavirus nonstructural protein 5 (nsp5). The "3C" in the common name refers to the 3C protease (3C pro ) which is a homologous protease found in picornaviruses .
