Optimizing lornoxicam-loaded poly(lactic-co-glycolic acid) and (polyethylene glycol) nanoparticles for transdermal delivery: / inflammation evaluation.

This study focused on developing a topical gel incorporating lornoxicam-loaded poly(lactic-co-glycolic acid) and polyethylene glycol (PLGA-PEG) blend nanoparticles to mitigate gastrointestinal (GIT) side effects and enhance therapeutic efficacy. Synthesized nanoparticles were subjected to characterization, permeation studies, and acute oral toxicity analysis post-incorporation into the gel using a S/O/W double emulsion solvent. The nanoparticles displayed a smooth, spherical morphology (170-321 nm) with increased entrapment efficiency (96.2%). LOX exhibited a permeation rate of 70-94% from the nanoparticle-infused gel, demonstrating favorable biocompatibility at the cellular level. The formulated gel, enriched with nanoparticles, holds promising prospects for drug-delivery systems and promising improved therapeutic outcomes for LOX.
