Nitazoxanide Therapy for Patients With COVID-19 Pneumonia
Summary
Multicenter, randomized, placebo-controlled, parallel, blinded, interventional, treatment clinical trial with two arms. Population: 500 Hospitalized patients with pneumonia derived from COVID-19 (Coronavirus Disease-19), either confirmed by RT-PCR (Real Time polymerase chain reaction), or suggested by typical findings on the computed tomography scan symptomatic. Experimental group: nitazoxanide 500mg 8 / 8 hours for 5 days. Control group: placebo 8/8 hours for 5 days.
