ABSTRACT
The anti-inflammatory agents dexamethasone (corticosteroid), and tocilizumab and sarilumab (IL6-inhibitors) are effective in the treatment of late COVID-19. Other anti-inflammatory agents, like anakinra (IL1-inhibitor), baricitinib and tofacitinib (JAK-inhibitors) and lenzilumab (GM-CSF-inhibitor) have also shown positive results in late COVID-19. For the treatment of early COVID-19, the inhalation corticosteroid budesonide is regarded as an off-label treatment option. Virus-inhibitors, like remdesivir, molnupiravir and nirmatrelvir/ritonavir decrease the risk of hospitalization and the development of severe COVID-19 by patients with early symptoms. Monoclonal antibodies have shown limited or no efficacy against the omicron-variant of SARS-CoV-2. Fluvoxamine, l-arginine, AT-527 and ensovibep are considered as potential promising new therapies for the treatment of early COVID-19.
