After being informed about the study and potential risks, all patients giving written informed consent will undergo a 1 day screening period to determine eligibility for study entry. At day 0, patients who meet the eligibility requirements will be randomized in a double blind manner (participant and investigator) in a 1:1 ratio to metformin glycinate (620 mg, taken orally, twice daily) plus standard treatment or placebo (taken orally, twice daily) plus standard treatment, both for 14 days.
The purpose of this study is to evaluate the efficacy and safety of the metformin glycinate and standard treatment of the hospital in hospitalized patients with Severe Acute Respiratory Syndrome secondary to SARS-CoV2.
