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 <i>via</i> microfluidic technology to systematically address the clinical challenges associated with frequent dosing regimens.

Pharmacokinetic evaluation in rats revealed that the NMP-loaded microspheres maintained relative stable plasma drug concentrations for approximately 10 days.

Additionally, antioxidant capacity, cytotoxicity, wound healing, prostaglandin E2 levels, IL-6 inhibition, and skin irritation tests were conducted. The optimized IN3-VA formulation exhibited a gelling temperature of 32.394 ± 0.842, a pH value of 4.780 ± 0.010 and a viscosity of 2473.33 ± 11.54 cP. It demonstrated specific mechanical properties, including hardness of 27.94 ± 1.30 g and adhesiveness of -97.00 ± 14.60 g.mm. The IN15-VA formulation showed improved parameters, with a hardness of 38.84 ± 3.33 g, adhesiveness of -126.35 ± 22.78 g.mm, pH value of 4.870 ± 0.010, viscosity of 3853.33 ± 30.55 cP, and a gelling temperature of 31.854 ± 0.345. Both formulations demonstrated sustained release behavior, releasing 60% of the medication <i>in vitro</i> over 6 h with no cytotoxic effects. 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 <i>in situ</i> gels hold promising potential in wound treatment due to their sustained release over 48 h.</p>","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}
