Core Tip

Core Tip: Treatment with famotidine demonstrated a comparatively better outcome in the survival rates of patients. A rapid recovery time, less duration of intensive care unit (ICU) stay among the survivors, favorable improvement in the computed tomography findings and an earlier viral clearance were observed in the famotidine treatment group which differ significantly in a t-test (P ≤ 0.05). The difference between the time to symptomatic recovery, ICU stay duration and the national early warning score-2 on discharge was not significant however, mean values were relatively less than the control. Nevertheless, survival benefit was not significant with the famotidine as an added treatment for severe coronavirus disease 2019.
