A mucoadhesive drug delivery system for local delivery of metronidazole through vaginal route was formulated. Films were prepared by solvent evaporation method using various compositions of Carbopol, hydroxypropylmethylcellulose, chitosan, Polyox and propylene glycol. The films were evaluated for their weight, thickness, surface pH, folding endurance, mechanical, drug content uniformity, in vit...

The objective of this study was to develop intranasal nanoemulsion and gel formulations for rizatriptan benzoate for prolonged action. Nanoemulsion formulations were prepared by constructing pseudo-ternary phase diagrams using lipophilic and hydrophilic surfactants and water. Various mucoadhesive agents were tried out to form thermo-triggered mucoadhesive nanoemulsions. Mucoadhesive gel formula...

Objective: The main objective of the current research work was to formulate and evaluate Bosewellia serrata extract loaded transferosomal topical gels. To overcome drawbacks associated with oral administration in Osteoarthritis treatment. Methodology: Transferosomes were developed using different ratios Phospholipon® 90G as phospholipid, Span-60 surfactant cholesterol fluidity buffer. selected ...

Abstract The review presents current research results for Carbopol-based microgels as yield-stress materials, covering three aspects: chemical, physical and rheological. Such a joint three-aspect study has no analog in the literature. chemical aspects of Carbopol polymers are presented terms cross-linking polymerization acrylic acid, their molecular structure, microgel formulation, polyacid dis...

mulation of semisolid bases, generally with a significant influence on their rheological properties. When organic amines are employed as neutralizing agents of carbopols, it is possible to gel many semipolar liquids and mixtures of these liquids with water. Compatibility of the polymer and non-polar solvents depends on the formation of ion pairs with the amine. Although alcohols are useful for ...

in this study, the effects of various hydrophilic (hpmc and carbopol 971) and plastic (ethylcellulose and eudragit rl100) polymers on the release profile of diltiazem hcl from matrix tablets were evaluated in-vitro. for this purpose, tablets containing 60 mg of diltiazem hcl along with various amounts of the aforementioned polymers were prepared using the wet granulation technique. tablets prep...
