In Vitro Studies of Controlled Release Alfuzosin Matrix Tablets Prepared with Ethylcellulose and Hydroxypropyl Methylcellulose
Extended release formulation of alfuzosin, an a-antagonist used for prostatic hypertrophy, is available in market. It is convenient for older patients to take only one tablet a day. Marketed alfuzosin formulation is three layered geomatrix tablet that requires special facilities, high cost, more time and complex operation than normal direct compression formulation. Therefore, a less compl...
متن کاملTheophylline-Ethylcellulose Microparticles: Screening of the Process and Formulation Variables for Preparation of Sustained Release Particles
Objective(s) The aim of this study was to formulate and evaluate microencapsulated controlled release preparations of theophylline using ethylcellulose as the retardant material with high entrapment efficiency. Materials and Methods Microspheres were prepared by water-in-oil-in-oil (W/O1/O2) emulsion-solvent diffusion (ESD). A mixed solvent system consisting of acetonitrile and dichloromet...
متن کاملPreparation of Sustained-Release Matrix Tablets of Aspirin with Ethylcellulose, Eudragit RS100 and Eudragit S100 and Studying the Release Profiles and their Sensitivity to Tablet Hardness
A sustained-release tablet formulation should ideally have a proper release profile insensitive to moderate changes in tablet hardness that is usually encountered in manufacturing. In this study, matrix aspirin (acetylsalicylic acid) tablets with ethylcellulose (EC), Eudragit RS100 (RS), and Eudragit S100 (S) were prepared by direct compression. The release behaviors were then studied in two co...

متن کاملThe Effect of Various Surfactants on Release Behavior of Procainamide HCl from Ethylcellulose Based Matrices
The effect of different kinds of surfactants in various concentrations incorporated in an inert matrix, on the release of procainamide hydrochloride, as a cationic model compound, was investigated in this study. Sodium lauryl sulfate and sodium stearate as anionic surfactants, cetyl pyridinium chloride and cetyltrimethyl ammonium bromide as cationic and span 60 and tween 80 as non-ionic surfact...
