Owing to its inherent physicochemical properties characterized by low oral bioavailability, rapid elimination half-life, and extensive first-pass metabolism, conventional formulations necessitate frequent dosing regimens to sustain therapeutic plasma concentrations. These pharmacological challenges collectively result in suboptimal patient adherence, marked plasma concentration fluctuations, and recurrent vascular irritation. To overcome these pharmacological constraints, this investigation engineered a novel drug-loaded microsphere system utilizing poly(5-(p-carboxyphenoxy) valeric anhydride (Poly(CPV)) as a biodegradable matrix material. The sustained-release microspheres were fabricated via microfluidic technology to systematically address the clinical challenges associated with frequent dosing regimens. The optimized microspheres exhibited a drug loading capacity of 5.59%, an encapsulation efficiency of 70.22%, and a uniform particle size distribution (43.98 ± 4.29 μm). In vitro release studies demonstrated sustained drug release over 14 days. Pharmacokinetic evaluation in rats revealed that the NMP-loaded microspheres maintained relative stable plasma drug concentrations for approximately 10 days. Biocompatibility assessments, including histocompatibility tests and in vitro cytotoxicity assays, confirmed the excellent biocompatibility of the Poly(CPV) microsphere. These findings suggest that Poly(CPV)-based microspheres prepared by microfluidics represent a promising drug delivery platform for poorly soluble small-molecule pharmaceuticals, offering controlled release characteristics and improved therapeutic outcomes.","PeriodicalId":20004,"journal":{"name":"Pharmaceutical Development and Technology","volume":" ","pages":"1-16"},"PeriodicalIF":2.5,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145030252","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}

Insulin release from buccal film was not affected by the extra barrier. The stability study indicated that the film did not show any changes.

They also decreased copper ion reduction and the release of nitric oxide, with cellular proliferation rates of 63% for IN3-VA and 73% for IN15-VA. Moreover, IN15-VA significantly reduced prostaglandin E2 levels, controlled IL-6 increase, and exhibited non-irritating properties. The results suggest that these vanillic acid-loaded in situ gels hold promising potential in wound treatment due to their sustained release over 48 h.","PeriodicalId":20004,"journal":{"name":"Pharmaceutical Development and Technology","volume":" ","pages":"905-922"},"PeriodicalIF":2.5,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144643106","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}
