title: General class of multiparticulate dissolution models.
abstract: The dissolution of multiparticulate systems under sink and nonsink conditions can be described rigorously according to a generally applicable formula on the basis of the single-particle dissolution model and the initial particle distribution. The kinetic model for log-normal systems dissolving under sink conditions is extended to nonsink conditions as a specific example. The equation presented describes a general class of multiparticulate models for various values of the dispersion parameter and the dissolution capacity coefficient.
