Evaluation of gellan gum fluid gels as modified release oral liquids.
Oral liquids are often preferred for drug administration to patients for whom swallowing is difficult, however, formulating modified release versions can be challenging. A potential route to achieve modified release in oral liquids is by using fluid (sheared) gels formed by introducing a shear field during gelation in gel-forming biopolymers. These fluid gels can act as pourable viscoelastic fl...
متن کاملControl Release from Low Acyle Gellan Gum Gels
Salt is a requirement material for human body but should be regulated as its excessive consumption might lead to heart disease and blood pressure. Processed foods due to high salt content might include about three quarter of the daily salt intake therefore many people consume more than their recommended allowances. Processed foods contain added salt for varieties of reasons namely to enhance th...
متن کاملDevelopment of mucoadhesive sprayable gellan gum fluid gels.
The nasal mucosa provides a potentially good route for local and systemic drug delivery. However, the protective feature of the nasal cavity make intranasal delivery challenging. The application of mucoadhesive polymers in nasal drug delivery systems enhances the retention of the dosage form in the nasal cavity. Several groups have investigated using low acyl gellan as a drug delivery vehicle b...
متن کاملPreparation and characterization of novel gellan gum hydrogels suitable for modified drug release.
Innovative hydrogels obtained by physical and chemical crosslinking of deacylated Gellan gum have been characterized in terms of water uptake, rheological properties and compressibility, and the behaviour of the tested materials, according to the type of the obtained network, is thoroughly discussed. The release from the various gels of loaded model molecules of different steric hindrance was a...
متن کاملModified Gellan Gum hydrogels with tunable physical and mechanical properties.
Gellan Gum (GG) has been recently proposed for tissue engineering applications. GG hydrogels are produced by physical crosslinking methods induced by temperature variation or by the presence of divalent cations. However, physical crosslinking methods may yield hydrogels that become weaker in physiological conditions due to the exchange of divalent cations by monovalent ones. Hence, this work pr...
