Antiviral Dosing Modification for Coronavirus Disease 2019-Infected Patients Receiving Extracorporeal Therapy

Previous literature regarding coronavirus disease 2019 outlined a presence of organ dysfunction including acute respiratory distress syndrome and acute kidney injury that are linked to mortality. Several patients require extracorporeal therapy. This review aims to gather available published resources including physicochemical and pharmacokinetic properties and suggests antiviral drug dosing adaptation for coronavirus disease 2019-infected critically ill patients receiving extracorporeal therapy. A literature search was performed using PubMed, clinical trial registries, and bibliographic review of textbooks and review articles. Unfortunately, no standard of pharmacologic management and recommendations of drug dosing for coronavirus disease 2019 infection for critically ill patients receiving extracorporeal therapy exist due to the limited data on pharmacokinetic and clinical studies. All available extracted data were analyzed to suggest the appropriate drug dosing adjustment. Antiviral drug dosing adjustments for critically ill patients receiving extracorporeal membrane oxygenation and continuous renal replacement therapy are presented in this review. Considering pathophysiologic changes, drug properties, and extracorporeal modalities, applying our suggestions is recommended.
