Development of Indomethacin Sustained Release Microcapsules using Ethyl Cellulose and Hydroxy Propyl Methyl Cellulose Phthalate by O/W Emulsification

Development of indomethacin sustained release microcapsules using chitosan-carboxymethyl- cellulose complex coacervation

Waree Tiyaboonchai and Garnpimol C. Ritthidej Development of indomethacin sustained release microcapsules using chitosan-carboxymethylcellulose complex coacervation Songklanakarin J. Sci. Technol., 2003, 25(2) : 245-254 Indomethacin sustained release microcapsules were prepared by complex coacervation of chitosan (CS) and carboxymethylcellulose (CMC) and then were hardened with glutaraldehyde (...

Release Kinetic Studies of Aspirin Microcapsules from Ethyl Cellulose, Cellulose Acetate Phthalate and their Mixtures by Emulsion Solvent Evaporation Method

The present study was oriented towards microencapsulation of aspirin and the study of its release kinetics. The desired encapsulation was achieved by emulsion solvent evaporation method using ethyl cellulose (EC), cellulose acetate phthalate (CAP) and their mixture (1:1) of polymeric constituents. Characterization of the formulations was performed by size, shape, drug loading efficiency and in-...

formulation of topical hydroalcoholic gel containing indomethacin 0.2% using carboxy methyl cellulose and hydroxyl propyl cellulose

Effects of microcrystalline cellulose on functional properties of hydroxy propyl methyl cellulose microcomposite films.

Edible films and coatings in foods can be used to increase shelf-life and improve organoleptic characteristics of foods by avoiding deterioration of food components and therefore promoting preservation of the final product. This study is the first to investigate the use of different size fillers for the purpose of preparing edible composite films with fillers < 1.0 microm in size. For this purp...

formulation of topical hydro alcoholic gel containing indomethacin 0.2% using carboxy methyl cellulose and hydroxyl propyl cellulose

background indomethacin is a nsaid (non-steroidal anti-inflammatory drug) that is used in treatment of pain and inflammatory. immediate and sustained release products of this drug have side effects, so a proper replacement is needed. use of the medicine via topical and cutaneous routs has advantages such as avoiding side effects on gastrointestinal; and supplying an amount of medicine in plasma...
