Besides, in a mouse model of SARS-CoV infection, prophylactic and early therapeutic dosing of remdesivir therapy effectively decreased viral load in lungs and improved pulmonary function[20].According to the previous rhesus monkey model of Ebola virus infection, an intravenous 10 mg/kg dose of remdesivir could lead to a lasting level of active triphosphate form in peripheral blood mononuclear cells (PBMCs), >10 μM, for at least 24 hours[15], and such data may be valuable in the same animal species with SARS-CoV-2 infection.
