Abstract

The invention provides a novel means for overcoming the problem of undue and irregular delay in the exhibition of the effect of medicine when a patient is administrated with an enterosoluble hard-capsulated medicament. The unexpected discovery that the key parameter ruling the smooth transfer of an enterosoluble capsule from the stomach to the intestinal canals is the overall specific gravity of the capsule has led to the establishment of the invention which proposes an enterosoluble hard-capsulated medicament having an overall specific gravity of at least 1.05 or, preferably, at least 1.10.
