1. PHYSICOCHEMICAL AND RHEOLOGICAL MODELING OF SYNERGISTIC INTERACTION OF SOME PLANT GUM EXUDATES.
ABSTRACT
The visco-elastic properties of Khayasenegalensis (KS gum), Anacardium occidentale (AO gum) and Acacia senegal (AS gum) blends in dilute solution were investigated. The gums were evaluated for intrinsic viscosity and the elastic component. Molecular conformation of the complex...
2. SURFACE ACTIVITY AND RELEASE PROPERTIES OF SOME TROPICAL GUMS IN ARTEMETHER AND ARTESUNATE SODIUM TABLET FORMULATIONS
ABSTRACT
Plant gums are natural polymers with low toxicity, high biodegradability and high compatibility with drugs making them useful as pharmaceutical excipients in solid, semi-solid and liquid formulations. This work was aimed at evaluating the surface activity and release properties...
3. EVALUATION OF CHRYSOPHYLLUM ALBIDUM (G. DON) FRUIT GUM AS A SUSTAINED RELEASE MATRIX IN TABLET FORMULATIONS
ABSTRACT
The goal of designing sustained release or controlled release delivery system is to reduce the frequency of dosing or to increase effectiveness of the drug by localization at the site of action, reducing the dose required or providing uniform drug delivery. Natural gums and pol...
4. THE USE OF GELATIN-ACACIA CO-PRECIPITATE (GELAC) IN THE FORMULATION OF SUSTAINED RELEASE MATRIX TABLETS OF DICLOFENAC SODIUM
ABSTRACT
Gums find application in tablet formulation as binder because of their adhesive nature. Natural gums are promising biodegradable polymeric materials. The aim of this study was to prepare a gelatin and acacia co-precipitate (GelAc) to be used as a release retardant in the formul...
