Aim: To formulate an aerosolized nanoliposomal carrier for remdesivir (AL-Rem) against coronavirus disease 2019. Methods: AL-Rem was prepared using modified hydration technique. Cytotoxicity in lung adenocarcinoma cells, stability and aerodynamic characteristics of developed liposomes were evaluated. Results: AL-Rem showed high encapsulation efficiency of 99.79%, with hydrodynamic diameter of 71.46 +/- 1.35 nm and surface charge of -32 mV. AL-Rem demonstrated minimal cytotoxicity in A549 cells and retained monolayer integrity of Calu-3 cells. AL-Rem showed sustained release, with complete drug release obtained within 50 h in simulated lung fluid. Long-term stability indicated >90% drug recovery at 4 degrees C. Desirable aerosol performance, with mass median aerodynamic diameter of 4.56 +/- 0.55 and fine particle fraction of 74.40 +/- 2.96%, confirmed successful nebulization of AL-Rem. Conclusion: AL-Rem represents an effective alternative for coronavirus disease 2019 treatment.
