Brief summary

SARS-CoV-2 infection is responsible for hypoxemic pneumonia, which is sometimes serious and associated with excess mortality. To date, with the exception of dexamethasone, which has shown clinical efficacy by reducing the mortality of infected patients, no other therapeutic strategy has demonstrated a curative clinical benefit, particularly in the initial stages facilitating viral eviction. . Based on the mechanism of action and the available data, diltiazem, administered in the first days post-infection, could facilitate viral eradication in these patients through the stimulation of the innate immune response of cells of the infected respiratory epithelium, actor in the fight against SARS-CoV-2. In this context, the investigators propose the DICOV trial, to demonstrate the ability of diltiazem to reduce the viral load more rapidly, in patients hospitalized for COVID-19 hypoxemic pneumonia.
