The global pandemic of novel coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has created an urgent need for effective antivirals. Remdesivir (formerly GS-5734) is a nucleoside analogue pro-drug currently being evaluated in COVID-19 clinical trials. ⋯ In pre-clinical models, remdesivir has demonstrated potent antiviral activity against diverse human and zoonotic β-coronaviruses, including SARS-CoV-2. In this article, we critically review available data on remdesivir with an emphasis on biochemistry, pharmacology, pharmacokinetics, and in vitro activity against coronaviruses as well as clinical experience and current progress in COVID-19 clinical trials.

We present a case of late initiation of remdesivir antiviral therapy in the successful treatment of a patient with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in a mixed medical intensive care unit of a community teaching hospital. A previously healthy 40-year-old man was admitted to the hospital 3 days after the onset of coronavirus disease 2019 (COVID-19) symptoms including dry cough, fever, and shortness of breath progressing to intubation and increased mechanical ventilator support. A request for compassionate use remdesivir was submitted on the same hospital day as the positive COVID-19 polymerase chain reaction result. ⋯ Sixty hours after initiating remdesivir, the patient was successfully extubated and able to transition to room air within 24 hours of extubation. Late initiation of remdesivir may be effective in treating SARS-CoV-2, unlike antivirals utilized for different disease states, such as oseltamivir, that are most effective when started as soon as possible following symptom onset. Urgent action is needed by regulatory agencies to work with drug manufacturers to expedite the study and approval of investigational agents targeting SARS-CoV-2 as well as to meet manufacturing demands.

Comparative Study Observational Study
Comparison of Hydromorphone versus Fentanyl-based Sedation in Extracorporeal Membrane Oxygenation: A Propensity-Matched Analysis.
Data comparing sedatives in patients receiving extracorporeal membrane oxygenation (ECMO) are sparse. However, it is known that the ECMO circuit alters the pharmacokinetic properties of medications via drug sequestration of lipophilic agents and increased volume of distribution. ⋯ The use of hydromorphone-based sedation in ECMO patients resulted in more days alive without delirium or coma while significantly reducing narcotic requirements.
