Abstract: The present disclosure provides a remdesivir oral delivery system bypassing the first pass hepatic metabolism. More specifically, the disclosure relates to an oral dosage form of remdesivir comprising a lipid based vehicle in an enteric capsule designed to be delivered at intestine to be absorbed by lymphatic pathway, therefore minimizing the first pass hepatic metabolism and improving the oral bioavailability. In some embodiments, the disclosure provides an oral dosage form comprising: (a) remdesivir; (b) a lipid-based vehicle comprising a lipophilic vehicle, an amphiphilic vehicle, a none-aqueous hydrophilic vehicle, or combinations thereof; and (c) an enteric capsule; wherein the remdesivir is dissolved or dispersed in the lipid-based vehicle; and, wherein the remdesivir and the lipid-based vehicle are in the enteric capsule. It also relates to methods of designing and making this dosage form, and methods of usage of this dosage form in the early treatment and prophylaxis of coronavirus infections, e.g.
