The developed B-DCNs loaded with BAR were characterized for particle size, polydispersity index (PDI), zeta potential (ZP), % yield and percent entrapment efficiency (%EE).Results: Based on the above evaluations, BAR-loaded DPC βCD NSs (B-CDN3) was optimized with mean size (345.8± 4.7 nm), PDI (0.335± 0.005), Yield (91.46± 7.4%) and EE (79.1± 1.6%). The optimized NSs (B-CDN3) was further confirmed by SEM, spectral analysis, BET analysis, in vitro release and pharmacokinetic studies. The optimized NSs (B-CDN3) showed 2.13 times enhancement in bioavailability in comparison to pure BAR suspension.Conclusion: It could be anticipated that NSs loaded with BAR as a promising tool for release and bioavailability for the treatment of rheumatic arthritis and Covid-19.Keywords: baricitinib, cyclodextrin, diphenyl carbonate, crosslinker, bioavailability, BAR, DPC
