To address this challenge, licorice-derived glycyrrhizic acid (GA) and LA were co-assembled into GA-LA (GLA) binary co-assembled <em>Glycyrrhiza</em> nanoparticles (BCGNs), which were subsequently incorporated into supramolecular hydrogel matrix. GLA BCGNs demonstrated a remarkable capacity to scavenge various reactive oxygen species (ROS) and facilitated the cascade process of O<sub>2</sub><sup>•−</sup>-H<sub>2</sub>O<sub>2</sub>-O<sub>2</sub> in vitro. Subsequently, GLA was dispersed in nano form into ovalbumin (OVA) and rhamnose (Rha) solutions, which were next self-assembled into OVA-Rha-GLA hydrogels. Remarkably, the introduction of Rha induced disordered secondary conformation of OVA, which decreased its mechanical properties and inherent binding energy, thereby shaping the three-dimensional supramolecular spatial structures of OVA-Rha-GLA networks. The assembly mechanisms indicated that the hydrogen bonding predominantly drove the assembly of loose supramolecular networks surrounded by -OH, -CH<sub>2</sub> and C<img>O bonds on the Rha and OVA. Notably, the conformational transformation facilitated faster LA release, confirmed by computational simulation analysis, which was conducive to acute inflammation curation. Therefore, OVA-Rha-GLA exhibited excellent anti-inflammation and ROS-scavenging versatilities, displaying improved oral bioavailability compared to hydrogels lacking BCGNs or Rha in cellular and animal acute inflammation experiments.

The main cause is the cochlear hair cell damage induced by oxidative stress and inflammation from ototoxic drugs, noise exposure or diabetes. Glycyrrhizic acid (GA), derived from edible herb licorice, is widely utilized in traditional Chinese medicine and clinical treatments for liver diseases. However, its potential in preventing hearing loss remains largely unexplored. Herein, we propose GA as a novel otoprotective agent and demonstrate its capability to prevent hearing loss. Our results show that GA effectively reduces oxidative stress and inflammation induced by cisplatin, aminoglycosides, or even noise and diabetes, thereby protecting cochlear hair cells. In hearing loss models, two commonly used administration methods were compared, with tympanic injection providing better protective effects than oral administration of GA. To enhance oral bioavailability, GA is employed as both the medicine and excipient, and formulated into micelles with curcumin, another extensively used bioactive compound. Interestingly, formulation parameters such as feeding ratio and temperature have little impact on micelle size but significantly affect the drug loading efficiency. The carrier-free strategy can achieve a high drug loading capacity and significantly increase the drug concentration in blood, offering improved preventive efficacy. Notably, the micelles also exhibit protection on kidneys and liver, and do not compromise the antitumor activity of cisplatin. Therefore, GA holds promise as an otoprotective candidate, with potential clinical applications for oral prophylaxis of hearing loss using the micellar formulation.</div></div>","PeriodicalId":14280,"journal":{"name":"International Journal of Pharmaceutics: X","volume":"9 ","pages":"Article 100340"},"PeriodicalIF":5.2,"publicationDate":"2025-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144170464","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}

Consequently, flowability is a crucial consideration in the design of formulations and must be considered throughout the development process when changes are introduced. Traditionally, understanding flow properties has required testing large amounts of material, particularly when evaluating formulation options. This has led to research into developing predictive flow models to reduce experimental burden. Current models with good predictive capacity, such as using granular bond number, require non-routine measurements such as mechanical surface energy. Three mixture designs, each using three pharmaceutical materials, were developed to investigate flow properties and allow the evaluation of a number of mixing models for predicting flowability with minimal experimental input requirements. The resultant models ranged in complexity from simple first order mixture models to more complex third order models with binary and ternary interaction parameters. An analysis of the experimental cost versus prediction accuracy suggested that while the more complex models delivered the most accurate predictions, a first order mass weighted model using inverse FFC was capable of providing good predictions in return for a more manageable experimental burden, with an R<sup>2</sup> value of 0.68, root mean square error of 2.88 and a mean absolute percentage error of 0.21.

Advanced statistical modeling was used to optimize RC/DG process parameters and subsequently binder compositions by employing process and mixture design experiments. The authors used microcrystalline cellulose (MCC), silicified MCC (SMCC), and dicalcium phosphate (DCP) as filler-binder examples in RC/DG experiments. Granule and tablet properties, including flowability, bulk and tapped densities, as well as resistance to crushing, were analyzed using compendial methods. The process design experiments confirmed that RC/DG reduces manufacturability compared to direct compression. Optimal processing conditions, balancing sufficient tablet strengths and granule formation, were identified to be between 20 (SCF * ϑ) [kN/cm] and ∼ 60 (SCF * ϑ) [kN/cm]. Thereby (ϑ) is defined as the screw-to-roll speed ratio and (SFC) as the specific compaction force. Mixture design experiments revealed optimal mixtures balancing SMCC, MCC, and DCP to achieve desired properties like low angle of repose, high bulk density, and strong tablets. These findings provide guidance for selecting formulations and process parameters in RC/DG applications. The derived ‘SCF * ϑ’- factor was found to effectively describe the granulation intensity. A superimposed mixture design model based on precise target values of the parameters bulk density, flow properties, and breaking force allowed identification of the best formulation.</div></div>","PeriodicalId":14280,"journal":{"name":"International Journal of Pharmaceutics: X","volume":"9 ","pages":"Article 100331"},"PeriodicalIF":5.2,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143776954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
