Effect of drug loading and molecular weight of cellulose acetate propionate on the release characteristics of theophylline microspheres.
Pharm. Res. 8(11) , 1396-400, (1991) Microspheres with 40, 50, and 60% drug loading of anhydrous theophylline core material were prepared by the emulsion-solvent evaporation method. Three different molecular weights of cellulose acetate propionate were used as encapsulating polymers. The geometr... |

Homogeneous preparation of cellulose acetate propionate (CAP) and cellulose acetate butyrate (CAB) from sugarcane bagasse cellulose in ionic liquid.
J. Agric. Food Chem. 59(10) , 5376-81, (2011) Cellulose acetate butyrate (CAB) and cellulose acetate propionate (CAP) were prepared homogeneously in a 1-allyl-3-methylimidazolium chloride (AmimCl) ionic liquid system from sugarcane bagasse (SB). The reaction temperature, reaction time, and molar ratio of... |

Design and evaluation of a dry coated drug delivery system with an impermeable cup, swellable top layer and pulsatile release.
Int. J. Pharm. 311(1-2) , 147-56, (2006) In this investigation a novel oral pulsatile drug delivery system based on a core-in-cup dry coated tablet, where the core tablet surrounded on the bottom and circumference wall with inactive material, is proposed. The system consists of three different parts... |

Ketotifen controlled release from cellulose acetate propionate and cellulose acetate butyrate membranes.
J. Mater. Sci. Mater. Med. 19(2) , 677-82, (2008) Ketotifen was immobilised in cellulose acetate propionate (CAP) membranes and in cellulose acetate butyrate (CAB) membranes. The characteristics of each system were evaluated under a range of experimental conditions. The topography and uniformity of the membr... |
