A Novel Dry Polymer Coating Technique as an Alternative for Taste Masking Small Multi-Particulate Dosage Forms in the 50-300 Micron Size Range
For many multi-particulate applications, the required particle size to achieve the proper drug load or to avoid poor mouth-feel has become very small, oftentimes in the 50-300 micron range. When these particles need to be taste masked, the amount of coating required can exceed 400% weight gain to properly taste mask the particles. Those high coating weight gains can lead to several processing problems, including extremely long processing times, agglomeration issues and large amounts of organic solvents. This study focused on an alternative method for taste masking small particles, utilizing a dry polymer coating technique.
