Abstract
A description is given of a pharmaceutical form for oral administration consisting of a two- or three-layers tablet, wherein at least one layer can rapidly swell by contact with biological and/or aqueous fluids, said swelling resulting in a considerable increase in the tablet volume. Said phenomenon determines a prolonged residence of the pharmaceutical form at the gastric level and therefore allows a slow release of the active ingredient from said pharmaceutical form to the stomach and/or the first tract of the intestine.
