USPTO Abstract
A novel drug delivery system, e.g. in the form of a solid dosage form or a liquid formulation based on a pharmaceutical multiple unit in the form of cores such as, e.g., coated cores. The pharmaceutical formulations are based on a novel principle allowing preparation of cores such as, e.g., cores in the form of pellets, i.e. substantially spheric particles which have such a mechanical strength (expressed in terms of friability) that the cores are sufficiently robust to substantially remain intact after having been subjected to coating by standard pharmaceutical procedures well known by a person skilled in the art such as, e.g., a coating process involving a fluidized bed process. A spray-drying process for the preparation of the pharmaceutical formulation is also described.
