Two polymorphs of remdesivir: crystal structure, solubility, and pharmacokinetic study

Abstract

Two polymorphic phases of the antiviral drug remdesivir (RDV), namely RDV-I and RDV-II are prepared and structurally characterized by single-crystal X-ray diffraction. Both RDV-I and RDV-II are solvent-free but exhibit different packing patterns in their crystals. RDV-I and RDV-II feature different pharmacokinetics, as revealed by in vitro and in vivo studies. This work highlights the significance of remdesivir drug formulations on the pharmacokinetics and ultimately patient outcome when combating the coronavirus disease 2019 (Covid-19).
