Here, we present mechanistic studies on metal-induced PS80 oxidation in the presence of hydrogen peroxide in acetate buffer. A total of 12 pharmaceutically relevant metal ions were tested, including Mn(II), Cu(II), Cu(I), Mg(II), Zn(II), Ca(II), Al(III), Pb(II), Sn(II), Co(II), Fe(III), Ni(II) and W(IV). The overall PS80 degradation was monitored by a fluorescence micelle assay (FMA) and the oxidation products were characterized by mass spectrometry (MS). Three metal ions, Cu(II), Co(II), and Fe(III), induced significant PS80 degradation and solutions containing these ions were subjected to further mechanistic studies. The extent of oxidation was dependent on both metal and peroxide concentrations. PS80 degradation catalyzed by Cu(II) and Co(II) was completely prevented by 250 µM and 500 µM ethylenediaminetetraacetic acid (EDTA), but only partially inhibited when catalyzed by Fe(III). The role for superoxide radical anion in the initiation of PS80 oxidation was examined by addition of Cu,Zn superoxide dismutase (SOD). The potential of the metal ions to generate free radicals was monitored with the spin trap 5,5-dimethyl-1-pyrroline N-oxide (DMPO), followed by LC-MS analysis. Degradation mechanisms, particularly the initiation of the oxidation chain reactions, are discussed for each metal.</div></div>","PeriodicalId":16741,"journal":{"name":"Journal of pharmaceutical sciences","volume":"114 7","pages":"Article 103799"},"PeriodicalIF":3.7,"publicationDate":"2025-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143899364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Temozolomide (TMZ), the first-line chemotherapeutic agent for GBM, offers only a modest survival benefit of 14.6 months and is associated with significant systemic side effects. Intranasal drug delivery has emerged as a promising non-invasive alternative, offering direct nose-to-brain (N2B) pathways to bypass the BBB. This method enables rapid and targeted drug transport while minimising systemic toxicity.</div></div><div><h3>Methods</h3><div>This study investigates the potential of desloratadine (DL), a repurposed non-sedating second-generation antihistamine, to enhance the therapeutic profile of TMZ in a nasal epithelial barrier model, representing the initial point of contact for N2B drug delivery. Cellular studies were conducted to evaluate the cytotoxicity, half-maximal inhibitory concentration, combination index, epithelial integrity, and drug transport properties of TMZ and DL alone and in combination. Transepithelial electrical resistance (TEER) and permeability coefficient (P_app) assays assessed barrier integrity and drug transport across the nasal epithelial cells, while cytotoxicity studies confirmed selective targeting of nasal cells during intranasal administration without affecting bronchial cell viability.</div></div><div><h3>Results</h3><div>DL demonstrated significant intracellular retention in nasal epithelial cells, while TMZ exhibited efficient transport across the nasal barrier with moderate cellular retention. The combination of TMZ and DL reduced cytotoxicity in nasal epithelial cells compared to TMZ alone, suggesting DL’s protective role in mitigating TMZ-induced cytotoxic effects. TEER and P_app analyses confirmed that both agents preserved nasal epithelial integrity, supporting their compatibility with N2B delivery. The synergistic effects of the combination therapy indicate an enhanced therapeutic profile for TMZ, with reduced off-target toxicity.</div></div><div><h3>Conclusion</h3><div>This study highlights the potential of a TMZ-DL drug combination therapy as a novel delivery strategy for brain tumour treatment. DL not only mitigates TMZ-induced cytotoxicity but also preserves the structural and functional integrity of the nasal epithelial barrier, addressing a critical translational gap in non-invasive drug delivery for brain tumours. Future work should focus on optimising dosing regimens and validating these findings in advanced 3D nasal models to facilitate clinical translation of this innovative therapeutic approach.</div></div>","PeriodicalId":16741,"journal":{"name":"Journal of pharmaceutical sciences","volume":"114 7","pages":"Article 103795"},"PeriodicalIF":3.7,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143894617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Further, we evaluated the aerodynamic performance post-filling to determine the relation of the process-induced tribo-charging on <em>in vitro</em> performance.

External lubricants decreased the charge for both types of capsules.

However, the effect of compression speed on capping has not yet been fully elucidated. In this study, numerical analyses were performed using the finite element method (FEM) with the Drucker-Prager cap and Perzyna models at 40 mm/s to further understand the effect of compression speed on capping occurrence. The calculated loading curves agreed with the experimental curves at different tableting speeds. Moreover, the simulation results confirmed that the stress distribution inside the tablet became more non-uniform with increased compression speed. Additionally, we aimed to develop a prediction method for capping tendency using FEM simulation. Predicting the capping tendency by comparing the residual stress and tablet strength at the edge of the tablet is challenging. On the other hand, accurate predictions were achieved by comparing the stress intensity factor with the fracture toughness of the tablets, based on fracture mechanics principles.
