Each beadlet comprises an extruded-spheronized inner core containing at least one medicament e.g. a slow release vitamin, an outer layer containing at least one medicament e.g. a fast release vitamin and a controlled release coating between the inner core and the outer layer which coating controls the release of the inner core medicament.
