Pharmaceutical Grade Gellan Gum: The Leading Vehicle for In-Situ Gelling and Controlled-Release Formulations

The application of gellan gum within the pharmaceutical industry is experiencing exponential growth, driven primarily by its unique ion-sensitive in-situ gelling characteristics. For advanced drug delivery systems, this biomaterial offers unparalleled structural control and predictability.

Advanced Applications in Ophthalmic Delivery Systems

Ophthalmic drug delivery frequently suffers from low bioavailability due to rapid nasolacrimal drainage and physiological tear turnover. Eye drops formulated with pharmaceutical-grade low acyl gellan gum directly overcome this limitation through a localized phase transition mechanism:

• Ion-Triggered Phase Transition: Upon instillation into the conjunctival sac, the fluid low acyl gellan gum solution reacts instantaneously with the ambient monovalent and divalent cations—specifically sodium ($Na^{+}$) and calcium ($Ca^{2+}$)—present naturally in human tear fluid.

• Prolonged Precorneal Retention: This ionic interaction triggers an immediate, highly localized gelation on the ocular surface, transforming the liquid drop into a thin, biocompatible, and non-blurring mucoadhesive hydrogel shield.

• Enhanced Bioavailability: By establishing this protective matrix, gellan gum significantly prolongs precorneal retention time, reducing precorneal drug elimination and boosting ocular bioavailability by more than three times compared to conventional aqueous eye drops.
