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...

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...

Formulation process is a very complex activity which sometimes implicates taking decisions about parameters or variables to obtain the best results in a high variability or uncertainty context. Therefore, robust optimization tools can be very useful for obtaining high quality formulations. This paper proposes the optimization of different responses through the robust Taguchi method. Each respon...
