The hyper-crosslinked β-cyclodextrin was dispersed in de-ionized water, and then lyophilised. The GLC-loaded-NS were prepared using different ratios of GLC to the previously developed NS<sub>1:4</sub> and evaluated for particle size, zeta potential, TEM, SEM, DSC, PXRD, FTIR, loading efficiency, pharmacokinetically, pharmacodynamically, histologically and effect of storage.</p><p><strong>Results: </strong>GLC:NS<sub>1:4</sub> showed highest solubility (46.36 ± 2.44%w/v), entrapment efficiency (36.1 ± 0.57%w/v), particle size 352 ± 6.1 nm and Z-potential -25.3 ± 0.3 mV. GLC:NS<sub>1:4</sub> exhibited porous, spherical nanoparticles, with confirmed drug encapsulation. In-vitro and in-vivo evaluations demonstrated an initial burst followed by sustained drug release, reducing blood glucose levels by 79.6 ± 0.43%. The effect of storage revealed no significant changes after 3 months.</p><p><strong>Conclusion: </strong>GLC-NS complexation improved oral bioavailability and extended drug release, suggesting better patient compliance.</p>","PeriodicalId":16391,"journal":{"name":"Journal of microencapsulation","volume":" ","pages":"352-367"},"PeriodicalIF":3.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143719897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
