Annual SZ: An Alternative Immunotherapy for COVID-19 and Long COVID

Since the outbreak of coronavirus disease 2019 (COVID-19) in late 2019 and early 2020, the identification of drugs to control severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and its symptoms has been a pressing focus of research. Cytokine storm and acute respiratory distress syndrome (ARDS) are the leading causes of mortality following infection. In this review, we discuss immune pathogenesis and four medications, including Remdesivir, Tocilizumab, Dexamethasone, and Annual SZ for COVID-19. A comparison of the effectiveness and therapeutic usage of drugs as reported in clinical trials and reports was made at different disease levels as well. Clinical studies indicate that Annual SZ with mild side effects was more affordable and might be more effective than other medications. Additionally, Annual SZ was capable of reducing the levels of pro-inflammatory cytokines as well as viral attachment and RNA replication.
