Core Tip
Core tip: Tocilizumab treatment is effective against IL-6 in Coronavirus Disease 2019 (COVID-19) patients, but it does not completely inhibit the inflammation and cytokine storm in all patients with COVID-19. In the clinical treatment of COVID-19 patients, attention should be paid to the timing of drug administration and other adjuvant treatments.
