Review of Contemporary Gel-Forming Agents in the Technology of Dosage Forms

This review addresses the general principles of the classification of gel-forming agents, and the characteristics, properties, preparation techniques, and mechanisms of gel formation of the major groups of gel-formers used in producing dosage forms (derivatives of cellulose, carbopols, polyethylene oxides, silicones, poloxamers, alginates, κ -ginanes, bentonite clays, and chitosan), to facilitate selection of polymers for developing dosage forms as gels.
