Engineered Brimonidine Tartrate Aminosomes as a Mucoadhesive Platform for Sustained Glaucoma Management: Optimization, In Vitro Characterization, and In Vivo Evaluation

Purpose: The objective of this study was to engineer and optimize a mucoadhesive, positively charged stearylamine-enriched liposomal platform, termed Aminosomes, to circumvent the biophysical barriers limiting the ocular bioavailability of Brimonidine Tartrate (BT), an alpha-2 adrenergic receptor agonist for glaucoma management. Methods: Aminosomes were synthesized using a tailored ethanol injection technique and optimized via a 32 × 21 full factorial design. Molecular integrity and crystallinit
