Improving Productivity Through Innovation


Start Date:9/6/2016

Start Time:9:00 AM CDT

Duration:60 minutes


Spray coatings of ethylcellulose for sustained drug release on multi-particulate dosage forms is common in the pharmaceutical industry, but can be disadvantageous because of long process times, need for organic solvent capabilities, and particulate agglomeration. Using a rotor process technology, ethylcellulose can be applied to drug layered beads as a dry powder; enabling the user to achieve high levels of weight gain in a short period of time while still demonstrating sustained release. Information will be presented comparing performance and productivity to traditional solvent-based Wurster coating and aqueous-based Wurster coating.
