A rapid increase of the drug release was observed when the dissolution profile of a sample made from a regular sugar nonpareil core (soluble) was compared with the sample made from a precoated nonpareil core (insoluble), which suggests that the drug release can be enhanced by the dissolution of the core.

The purpose of this work was to investigate drug release from film-coated chlorpheniramine maleate (CPM) nonpareils (sugar spheres) and the effect of water influx on the drug release mechanism.
