The aim of this study was to evaluate the non-steroidal NR-loaded nanocochleate hydrogel (NR-NC-G) for its skin permeation, safety, and efficacy in the treatment of psoriasis. First, nanoliposomes (NR-LIPO) were prepared and further chelated using calcium chloride to transform them into nanocochleates (NR-NCs). NR-NCs exhibited rolled sheet-like nanosized particles with a hydrodynamic diameter of approximately 160–170 nm, an encapsulation efficiency of 81–82%, and good colloidal stability, as indicated by a <em>ζ</em>-potential of −27 mV. To achieve a local reservoir-like action, nanocochleates were loaded into a hydrogel comprising of combination of Carbopol 934P and sodium alginate. NR-NC-G was characterised for its physical and rheological characteristics, and it exhibited uniform drug loading, long-term stability, and the ability to scavenge reactive oxygen species (ROS), as validated by various antioxidant assays. Furthermore, NR-NC-G reduced cellular ROS levels, nitrate accumulation, and mitochondrial healing ability in a lipopolysaccharide-stimulated RAW264.7 inflammation model, thereby proving its enhanced antioxidant and anti-inflammatory effects. The <em>ex vivo</em> skin permeation and dermatokinetic studies showed that NR-NC-G exhibited high permeation across the excised skin of BALB/C mice.

Theophylline is used for its bronchodilator and anti-inflammatory effects, but its clinical use is declining due to its narrow therapeutic index and metabolism by cytochrome enzymes, which increases the risk of drug interactions and toxicity. Chrysin, a BCS class II flavonoid, exhibits anti-inflammatory and antioxidant activities and is reported to inhibit cytochrome enzymes. Drug–drug eutectic mixtures are increasingly explored to enhance the solubility and bioavailability of poorly water-soluble drugs. In this context, a eutectic mixture of chrysin and theophylline was prepared using a simple, eco-friendly grinding method, with theophylline (a BCS class I drug) serving as a coformer. The prepared eutectic was characterized by differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR), hot stage microscopy (HSM), powder X-ray diffraction (PXRD), thermogravimetric analysis (TGA), scanning electron microscopy with energy dispersive spectroscopy (FE SEM-EDS), <em>in vitro</em> dissolution studies and <em>in vivo</em> pharmacokinetic evaluation in Wistar rats. DSC studies confirmed eutectic formation as its melting point was below those of chrysin and theophylline. They also confirmed a stoichiometric ratio of 1 : 2 between chrysin and theophylline. FTIR studies suggested intermolecular hydrogen bonding between chrysin and theophylline. The eutectic mixture significantly improved the aqueous solubility and dissolution rate of chrysin. Pharmacokinetic studies in rats showed a 3-fold increase in area under the curve (AUC) and a 2.87-fold increase in relative bioavailability of chrysin.

The extracted JLP was dried, powdered and subjected to several characterizations, such as FTIR spectroscopy, DSC, XRD, scanning electron microscopy, zeta potential analysis, particle size analysis, tests for the presence of phytochemical constituents, elemental analysis, and stability study in an aqueous environment, along with characterizing other physicochemical properties. Diclofenac sodium-incorporated granules were prepared using 2.5%, 5%, 7.5% and 10% w/w JLP concentrations, and the prepared granules were evaluated and compressed into tablets. The formulated tablet batches were evaluated for disintegration, drug release and kinetics study. The obtained results were compared with those of similar concentrations of starch and PVP K-30 batches used as tablet binders. Results of FTIR spectroscopy and DSC study established the compatibility between JLP and diclofenac sodium (DS) in the formulation.

To achieve the sustained release of HA from the lens, a chemical modification of the polymer surface was developed to allow the lens surface to be covalently linked with a semi-interpenetrating network (IPN) layer containing entrapped HA after deposition by nES. Additional zein barrier layers applied by nES over the HA layer led to further reduction in the release rate of HA from the lenses. The results confirmed that the selective nES deposition allowed modification of the lens surface without affecting optical properties in the central vision zone of the soft contact lenses. The results suggested that the HA release kinetics can be strongly affected by multiple factors, including the degree of crosslinking, the molecular size of the crosslinker, the addition of a photoinitiator and the polymeric barrier layer.
