Abstract
PURPOSE: The goal of this study was to develop dexamethasone-loaded tear-driven phase transition microemulsions (PTMEs) to effectively treat uveitis. METHODS: PTMEs were prepared using the oil titration method. Physicochemical parameters,release, and ocular irritation studies were performed. Thestudy, total cell count, and total protein content were estimated on the rabbit eye model. RESULTS: The study revealed that developed PTMEs had nanoglobule sizes, acceptable physicochemical properties, and prolonged drug release. Ex-vivo and in-vivo studies concluded that higher permeability and improved anti-inflammatory properties were observed for PTMEs compared to marketed formulation. CONCLUSION: The prepared PTMEs showed a sustained release pattern and enhanced therapeutic effectiveness, making them a promising alternative to conventional eye drops for treating uveitis.
