Title
(EN) DRY POWDER ANTIVIRAL COMPOSITIONS AND THEIR USE FOR TREATING VIRAL INFECTION
(FR) COMPOSITIONS ANTIVIRALES EN POUDRE SÈCHE ET LEUR UTILISATION DANS LE TRAITEMENT D'UNE INFECTION VIRALE
Abstract
(EN) Provided herein are dry powder antiviral compositions, each comprising a microparticle of a pharmaceutically acceptable excipient and nanoparticles of an antiviral, wherein the surface of the microparticle is coated with the nanoparticles. Also provided herein are methods of their use for treating, preventing, or ameliorating one or more symptoms of a viral infection.
(FR) L'invention concerne des compositions antivirales en poudre sèche dont chacune comprend une microparticule d'un excipient pharmaceutiquement acceptable et des nanoparticules d'un antiviral, la surface de la microparticule étant enrobée par les nanoparticules. L'invention concerne également des méthodes d'utilisation de celles-ci pour traiter, prévenir ou améliorer un ou plusieurs symptômes d'une infection virale.
