DEX MCs were physically perfused into LPMPs via negative pressure to form a combined system (DEX MCs+LPMPs). Physicochemical properties, <i>in vitro</i> drug release, pharmacokinetics, and biocompatibility were evaluated. Guinea pigs were used for intratympanic injections of DEX MCs, LPMPs, or DEX MCs+LPMPs.</p><p><strong>Results: </strong>The DEX MCs+LPMPs system enabled simultaneous release of both drugs, with DEX exhibiting superior pharmacokinetics (sustained perilymph concentrations up to 7 days) compared to DEX MCs alone. LA release from LPMPs demonstrated prolonged kinetics without burst release. SEM confirmed DEX MCs were localized within/on LPMPs and adhered to the round window membrane (RWM). Histological analysis revealed normal cochlear morphology and no inflammatory response, confirming biocompatibility.</p><p><strong>Conclusions: </strong>This novel codelivery system combining microcrystals and porous microspheres achieves sustained dual-drug release, enhances therapeutic efficacy, and offers a promising strategy for managing hearing loss via intratympanic administration.</p>","PeriodicalId":94336,"journal":{"name":"Journal of otology","volume":"20 3","pages":"190-197"},"PeriodicalIF":0.0,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12510363/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145260521","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}
