Objective to hydroxyl armour cellulose, drugs for skeleton materials from hydroxyl armour cellulose skeleton externally to analyze, release factors medicine colon positioning. Methods for model with metronidazole, adopt wet granule pressure prepared metronidazole hydroxyl armour cellulose, through the skeleton of the experimental results release release medium ionic strength, speed, different testing methods, and release of medium pH medicine slice influence of skeleton. Results the average method was OARS release time (MDT) and there is no obvious difference turn basket, Different medium pH value, drug release in the release pH6.8 phosphat buffer solution (PBS) in the second fastest, distilled water, 0.1 mol/L acid salt slowest, The drug release with the release of medium ionic strength increasing slows down, The drug release speed increases with the accelerated.Conclusion) can effectively control a cellulose skeleton in the drug release, it is a good hydrophilic skeleton materials.Keywords,Hydroxyl armour cellulose, Metronidazole, Slow-release, Skeleton slice.
