A Comparison of Spherical Core Materials Used for Controlled Release Drug Layering Processes
Three different spherical core materials for use in API layering processes; sugar/starch spheres, microcrystalline cellulose (MCC) spheres and novel maltodextrin/starch (M/S)
spheres were coated with 40% Acetaminophen in a dry powder layering process. The three core materials were evaluated both before and after the drug layering for sphericity, aspect ratio, particle size distribution and friability. The novel maltodextrin/starch spheres either equaled or out-performed the more established sugar/starch and MCC spheres in each category.
