Background. An in-silico screen identifed mebendazole with potential antiviral activity that could be a repurposed drug against SARSCoV-2. Mebendazole is a well-tolerated and cheap antihelminthic agent that is readily available worldwide and thus could be a
therapeutic tool in the fght against COVID-19. Methods. Tis is an observational retrospective study of PCR-confrmed COVID-19
patients who received mebendazole with the intention-to-treat. Te study included an inpatient cohort (157 inpatients) and an outpatient
cohort (185 outpatients). Of the 157 inpatients and 185 outpatients, 68 (43.3%) and 94 (50.8%) received mebendazole, respectively.
Patients who presented within the same timeframe but did not receive mebendazole were used as controls. Patients received standard-ofcare treatment including remdesivir, dexamethasone, and anticoagulants as deemed necessary by the treating physician. Te following
clinical outcomes were evaluated: for the inpatient cohort, length of stay (LOS) at the hospital, need for ventilation (combined invasive
and noninvasive), and mortality; for the outpatient cohort, time to symptom resolution, need for hospitalization, and mortality. Results.
For the inpatient cohort, the median age did not difer between the treatment and control groups; 62 (56, 67) vs. 62 (56, 68), P, and there
was a comparable proportion of males in both groups; 43 (63%) vs. 55 (62%), P � 0.85. Te hospital LOS was 3.5 days shorter in the
treatment group compared to the..

'study, the use of mebendazole in COVID-19 patients was associated with shorter '
'hospitalizations in the inpatient cohort and shorter durations of symptom resolution in the '

'and preclude drawing conclusions about clinical efficacy. Further studies are needed to '
'examine the role of mebendazole in the treatment of COVID-19 patients.</jats:p>',
