A beta-blocker, Carvedilol (CRV) has recently been reported as an off-label option for the management of cardiovascular disorders in pediatric patients. CRV exhibits a pH-dependent solubility and undergoes extensive hepatic metabolism, resulting in low oral bioavailability. Mesoporous silica nanoparticles (MSNs) of two types (MCM-41 and SBA-15) were loaded with CRV at three saturation levels to improve its dissolution rate. At high saturation level, CRV-loaded SBA-15 showed superior dissolution with a dissolution efficiency of 72.42 % and significant dissimilarity (<em>f</em><sub>1</sub> = 211.80, <em>f</em><sub>2</sub> = 16.89) compared to pure CRV, demonstrating enhanced solubility and dissolution rate due to its amorphous transformation and large pore diameter. Thermal and diffractometry analysis revealed the adsorption of CRV to MSNs in an amorphous state. CRV-loaded SBA-15 was incorporated into gel bases, and the amount of CRV released from triple-layer loaded gels was found to be higher than monolayer-loaded formulations. The <em>ex vivo</em> skin permeation study revealed a significant enhancement of drug release and permeation for CRV-loaded SBA-15 gel formulations (714.49 ± 38.49 µg/cm<sup>2</sup>) after 24 h, compared to the control (236.19 ± 18.93 µg/cm<sup>2</sup>), with flux increased by 62 %.

The focus of the study lieson incompatibilities observed in multidose formulations containing non-ionic surfactants and preservatives. Previous research has shown that above a critical concentration, phenol reduces the cloud point of polysorbate surfactants to room temperature or lower. Here, it is demonstrated that for BSA-polysorbate solutions, phenol-induced incompatibility is primarily controlled by this depression of the surfactant cloud point, resulting in turbidity and/or precipitation. However, for formulations with human growth hormone (hGH) in isotonic salt solutions, the precipitation mechanism is instead driven by protein-phenol interactions. The precipitation is affected by the concentration of sodium chloride and at low salt concentrations the incompatibility is again controlled by depression of the surfactant cloud point. The concentration of salt needed for protein induced precipitation seems to follow the Hofmeister series, with sodium chloride and sodium sulphate inducing precipitation at a lower salt concentration than sodium nitrate. Notably, non-ionic tonicity agents, such as glucose and mannitol, which are known to impact the surfactant cloud point depression of phenol, do not induce precipitation of hGH in the presence of phenol. In the system containing polysorbate, phenol and hGH, salt-triggered protein precipitation occurs at slightly higher sodium chloride concentrations than in solutions without polysorbate. This indicates a stabilizing effect of polysorbate on hGH below the cloud point. However, the stabilising effect is surfactant dependent, and in the presence of dodecyl maltoside, hGH precipitation occurs at much lower sodium chloride concentrations than for solutions with polysorbates. This illustrates the complexity of the interplay of excipients with each other and with the active ingredient (the protein) in the development of multidose pharmaceutics.</div></div>","PeriodicalId":14187,"journal":{"name":"International Journal of Pharmaceutics","volume":"676 ","pages":"Article 125624"},"PeriodicalIF":5.3,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143869472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To tackle this difficulty, we herein propose a strategy of “selective accelerated activation of MSC by photothermal effect (PTE)” based on our previous work of “laser-controlled platelet activation”. <em>In vitro</em> experiments presented that a photothermal agent (Indocyanine green, ICG) could be loaded by bone marrow-derived MSC (BMSC), which facilitated temperature increase under laser irradiation, leading to the speed differentiation and maturity of BMSC. Further findings revealed that PTE prevented BMSC from oxidative stress, thereby reducing inflammation and apoptosis. The ICG-loaded BMSC, which mixed with hydrogel, was further covered on the acute wounds in rats, promoting wound healing and blood vessel regeneration under laser irradiation. In-depth RNA-sequencing results indicated that PTE treatment led to the differentially expressed genes (DEGs) enriched in autophagy and PI3K signaling pathways, as confirmed by the increased expression of autophagy-associated biomarkers and observed autophagosome in BMSC. Furthermore, the HSP90 was activated in response to the PTE, which inhibited PI3K signaling. Finally, the silence of HSP90 abolished PTE-driven PI3K blockage, autophagy, and differentiation of BMSC. To summarize, PTE could facilitate the differentiation of MSC by triggering HSP90-mediated autophagy, which provides a novel approach for controlled MSC differentiation and the potential application of MSC cytopharmaceutics in wound repair.</div></div>","PeriodicalId":14187,"journal":{"name":"International Journal of Pharmaceutics","volume":"676 ","pages":"Article 125631"},"PeriodicalIF":5.3,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143869470","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While mannitol and leucine are widely used in inhalation formulations, their potential to enhance systemic drug delivery via the pulmonary route remains largely unexplored. This study utilizes the nanocrystal agglomerates (NCAs) approach to develop an inhalable NSAID formulation, with ketoprofen (KTP) as a model drug. Wet media milling and nano spray drying were employed for NCA fabrication, and the roles of mannitol and leucine were evaluated individually and in combination. Notably, their combination exhibited synergy, overcoming limitations observed with individual excipients. Mannitol-based sample (K1M) reduced aerosol performance by increasing the mass median aerodynamic diameter (MMAD) to 4.5 µm, whereas leucine-based sample (K1L) improved aerosolization but resulted in a low MMAD (<1 µm), suggesting a high tendency for exhalation. The combined mannitol-leucine formulation (K1ML) achieved optimal aerosol performance, balancing dispersibility and controlled deposition. K1ML also exhibited the fastest drug release (99 % in 5 min) and enhanced permeability across the alveolar barrier while maintaining biocompatibility. Pharmacokinetic analysis confirmed that inhaled K1ML provided superior bioavailability (AUC 73 µg·h/mL) compared to oral KTP nanosuspension (42 µg·h/mL) and raw KTP (9 µg·h/mL). Nonetheless, prolonged inhalation in asthmatic models (ovalbumin-sensitised rats) impaired pulmonary function, emphasizing the need for dose optimization. These findings demonstrate that the mannitol-leucine combination in NCAs enhances systemic NSAID delivery, optimizing both aerosol performance and bioavailability.

NPs have emerged as promising candidates for drug delivery systems due to their unique physicochemical properties, which enable them to interact with biological systems at the molecular level. Among these, soft nanocarriers, such as niosomes, and hard nanocarriers, such as Iron Oxide Nanoparticles (IONPs), offer distinct advantages for targeted therapy and diagnostics. This study provides a comprehensive, multi-disciplinary evaluation of two distinct types of nanoparticles: soft nanocarriers (niosomes, NVs) and hard nanocarriers (IONPs), by examining their physicochemical properties, cellular uptake, and cytotoxicity profiles. This comparative analysis seeks to highlight the different behaviour of soft and hard nanoparticles in drug delivery applications, with a particular focus on the impact of surface modifications. The addition of chitosan to sample NVsB not only resulted in an increase in particle dimensions but also shifted the ζ-potential to positive values which could enhance the interactions with cell membranes, improving cellular uptake. As desired, the obtained ζ-potential value of NVsB-Chit was comparable to that of the commercial coated ferrofluid. In addition to the traditional characterization techniques, this study integrates advanced analytical methods, such as Atomic Force Microscopy (AFM), complementing traditional techniques such as Dynamic Light Scattering (DLS), to assess the nanoscale topography of both types of nanoparticles. Cytotoxicity studies on Calu-3 lung adenocarcinoma cells were conducted to evaluate the biocompatibility of the nanoparticles, demonstrating that NVs and FluidMAG exhibited minimal cytotoxic effects, particularly at lower concentrations. Cell internalization was confirmed for IONPs by magnetic cell separation whereas confocal microscopy analysis has been conducted for calcein-loaded NVs intracellular visualization. By integrating structural, chemical, and biological evaluations, we take an interdisciplinary approach which could also enable us to explore how variations in nanoparticle design (such as surface charge, size and coating) affect their performance in drug delivery and diagnostics. Moreover, combining physicochemical characterizations (e.g., hydrodynamic diameter, zeta potential and nanoparticles morphology) with biological evaluations (e.g., cellular uptake and safety profiles) allows for a holistic assessment of these nanocarriers to gain a comprehensive understanding of their behaviour and performance.
