WHAT IS GELLAN GUM AND ITS ROLE IN PHARMACEUTICALS?
Gellan gum is a high molecular weight anionic polysaccharide produced by fermentation of the bacterium Sphingomonas elodea. It functions as a gelling agent, stabilizer, emulsifier, and thickener in pharmaceutical formulations. Its key attributes include the ability to form clear, heat-stable gels, compatibility with a wide range of active pharmaceutical ingredients (APIs), and the formation of low-viscosity solutions at high concentrations, facilitating drug delivery. Gellan gum is categorized into two main types: low-acyl and high-acyl, differing in their gel rigidity and texture. Low-acyl gellan gum forms brittle gels, while high-acyl gellan gum produces more elastic gels. This versatility allows its application in diverse pharmaceutical dosage forms, including tablets, capsules, oral suspensions, topical preparations, and parenteral formulations [1, 2].

GELLAN GUM IN PHARMACEUTICAL APPLICATIONS: SPECIFIC USES AND FORMULATION BENEFITS
Gellan gum's unique physicochemical properties make it an indispensable excipient in various pharmaceutical dosage forms:
- Oral Suspensions and Syrups: Gellan gum is utilized to suspend insoluble APIs, preventing sedimentation and ensuring uniform dosage. Its ability to form a gel network at low concentrations provides excellent suspension stability without imparting an overly viscous mouthfeel [6]. For example, in pediatric formulations where palatability and ease of administration are critical, gellan gum's neutral flavor and texture are advantageous.
- Tablet Manufacturing: Gellan gum can act as a binder and disintegrant in tablet formulations. Its gelling properties contribute to the mechanical strength of tablets, while its ability to rapidly hydrate and swell upon contact with gastrointestinal fluids aids in tablet disintegration and API dissolution, thereby improving bioavailability [9].
- Parenteral Formulations: In injectable drug delivery systems, particularly for controlled-release applications, gellan gum can form microparticles or gels that encapsulate APIs. This allows for sustained drug release over extended periods, reducing the frequency of administration. Its biocompatibility and low immunogenicity are critical for parenteral applications [10].
- Topical and Ophthalmic Preparations: Gellan gum's ability to form clear gels with tunable viscosity makes it suitable for topical creams, ointments, and ophthalmic solutions. It provides the desired consistency and aids in the even spreadability of the formulation while ensuring the stability of the active ingredient [1].
- Dental Applications: Gellan gum is used in dental gels and rinses, providing a vehicle for antimicrobial agents or therapeutic compounds, ensuring prolonged contact time with oral tissues.
