Pharmacokinetic Basis of the Hydroxychloroquine Response in COVID-19: Implications for Therapy and Prevention
In Silico analysis of HCQ treatment showing concluding that HCQ may affect viral clearance if administered early enough when the virus is still confined to the pharyngeal cavity; HCQ's effects against SARS-CoV-2 might be exerted more through enhanced cell-mediated immunity than direct antiviral effects; and the effects of HCQ on SARS-CoV-2 viral load may be missed in clinical trials if measurements are not done at the peak of viral replication; and the effects are only evident at dosages able to guarantee a certain plasma drug concentration, i.e., > 400 mg/day.
