Article Abstract
Biopharmaceutics Classification System Class II and IV drugs face significant challenges owing to poor water solubility, restricting their formulation in liquid delivery forms. The use of polymers, including the loading of drugs into nanoparticles, has attracted attention as an effective strategy for improving the solubility of poorly water-soluble drugs. These polymer carrier systems possess a hydrophilic outer shell and a hydrophobic inner core that can encapsulate poorly water-soluble drugs and improve their dispersibility in aqueous environments. Nanosizing techniques provide advantages including increased surface area and dissolution rate. Polymeric carrier systems also provide enhanced delivery efficiencies to specific tissues via passive and active targeting. This review article describes the development of solubilized formulations of water-insoluble drugs using several functional polymers, including polyvinyl alcohol, hyaluronic acid, and styrene-maleic acid copolymers.

The study explored HSPiP and QbD-(quality by design) enabled optimized cubosomes for sustained drug release, improved permeation, and enhanced oral bioavailability. OCUB1 (the optimized product) was characterized for size, zeta potential (ZP), thermal analysis, and surface roughness. drug release and hemolysis studies were carried out using a dialysis membrane and rat erythrocytes (4 % suspension), respectively.

Background: Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used to manage pain and inflammation but are associated with gastrointestinal and cardiovascular risks, especially with COX-2 inhibitors. Topical delivery systems offer a safer alternative by minimizing systemic exposure; however, poor solubility and limited skin penetration remain challenges. Enhancing solubility through solid dispersion and incorporating it into a gel formulation may improve permeability and therapeutic effectiveness, addressing the need for safer and more efficient topical NSAID delivery.

Oral administration is the preferred route for drug and bioactive delivery, although it raises great challenges due to the involvement of the gastrointestinal system and limited bioavailability. Herein, a novel submicron-oleogel particle system was developed using micro-structured edible oil to address the challenges associated with the low bioavailability of oral hydrophobic compounds. Oleogel particles were prepared using β-sitosterol and γ-oryzanol as oil structuring agents with dispersed dasatinib as a model drug.

The Forearm Controlled Application Test (FCAT) is widely used to assess skin irritancy and drying potential of rinse-off product but limited by its low throughput and long testing duration. To address these limitations, we explored the development of predictive models using New Approach Methodology (NAM) as a screening tool for evaluating skin mildness potential of rinse-off products. The skin irritancy and drying potential of standard surfactants were evaluated through multiple in vitro assays to identify relevant biomarkers, including a skin irritation bioassay by using Human Reconstituted Skin, a protein solubilization assay by using Zein test and a lipid solubilization assay by using Fatty Acid Methyl Ester (FAME) test.
