A randomized, double-blind study on the efficacy of oral domperidone versus placebo for reducing SARS-CoV-2 viral load in mild-to-moderate COVID-19 patients in primary health care.

Introduction: The clinical effect of domperidone against COVID-19 has been investigated in a double-blind phase III clinical trial (EudraCT number 2021-001228-17). Domperidone has shown in vitro antiviral activity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and potential immudolatory properties through the stimulation of prolactin secretion.

Patients And Methods: The efficacy of oral domperidone plus standard of care (SOC;  = 87) versus placebo plus SOC ( = 86) was evaluated in a 28-day randomized double-blind multicentre study in primary health care centres.
