Specialized pro-resolving mediators (SPMs) offer a novel therapeutic paradigm by actively promoting the resolution of inflammation and tissue regeneration without compromising host defense. However, the clinical translation of SPMs is hindered by their rapid degradation, low bioavailability, and poor localization to inflamed tissues. Smart biomaterial-based delivery systems, particularly stimuli-responsive hydrogels, have emerged as promising platforms to overcome these barriers. These systems enable controlled, localized, and environment-triggered release of SPMs, enhancing their stability and therapeutic efficacy. Preclinical studies in models of oral inflammation demonstrate that hydrogel-mediated SPM delivery not only resolves inflammation but also preserves tissue structure and promotes regeneration. Future strategies will focus on optimizing dosing protocols, ensuring long-term bioactivity, and addressing regulatory and manufacturing challenges to enable clinical adoption. By enhancing the delivery and sustained bioactivity of SPMs, biomaterial-based strategies have the potential to fundamentally transform the management of oral inflammatory diseases and advance regenerative dental therapies.","PeriodicalId":22959,"journal":{"name":"Therapeutic delivery","volume":" ","pages":"975-988"},"PeriodicalIF":3.4,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12574571/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145233393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Olaparib (OLA) BCS-IV class drug, is an inhibitor of the poly(ADP-ribose)polymerase enzyme.

In this study, nanostructured lipid carriers (NLCs) were prepared to mitigate OLA's side effects by reducing the dose without compromising efficacy.Materials and methods: OLA-NLCs were formulated, and a Design of Experiments optimization technique was utilized to assess essential formulation parameters systematically. Investigations were conducted on particle size, polydispersity index, zeta potential, encapsulation efficiency, release, and stability assessments. The impact of NLCs was evaluated on MCF-7 and MDA-MB-231 cell lines.Results: OLA-NLCs were evaluated for particle size (134.0 ± 2.56 nm), PDI (0.32 ± 0.01), ZP (-37.7 ± 0.89 mV), and EE (97.28 ± 1.48%). The in-vitro release profile of OLA-NLCs showed a sustained release pattern for 72 h. OLA-NLCs showed a concentration-dependent effect on cell viability for 24 h and 72 h. The uptake of OLA-NLCs was almost 1.75 and 3.69 times higher for MCF-7 and MDA-MB-231, respectively, compared to free-OLA.
