RCT with 25 nitazoxanide patients and 25 control patients, showing improved virological and clinical outcomes with treatment.
Authors also perform an in vitro study in Vero E6 cells showing 90% inhibition with 0.5µM, with no cytotoxicity. NCT04348409.
risk of death, 66.7% lower, RR 0.33, p = 0.25, treatment 2 of 25 (8.0%), control 6 of 25 (24.0%), NNT 6.3.
risk of mechanical ventilation, 62.5% lower, RR 0.38, p = 0.17, treatment 3 of 25 (12.0%), control 8 of 25 (32.0%), NNT 5.0.
relative severity scores, 20.2% better, RR 0.80, treatment 25, control 25.
hospitalization time, 55.7% lower, relative time 0.44, p = 0.02, treatment 25, control 25.
risk of no virological cure, 89.8% lower, RR 0.10, p = 0.03, treatment 0 of 23 (0.0%), control 4 of 19 (21.1%), NNT 4.8, relative risk is not 0 because of continuity correction due to zero events (with reciprocal of the contrasting arm), day 21.
Effect extraction follows pre-specified rules prioritizing more serious outcomes.

Please send us corrections, updates, or comments. Vaccines and treatments are both valuable and complementary. All practical, effective, and safe means should be used. Elimination of COVID-19 is a race against viral evolution. No treatment, vaccine, or intervention is 100% available and effective for all current and future variants. Denying the efficacy of any method increases mortality, morbidity, collateral damage, and the risk of endemic status. We do not provide medical advice.
