Abstract
The invention concerns a mutliparticulate pharmaceutical form with delayed and timed release for starting to make the active principle available 4 to 8 hours after said pharmaceutical form has been ingested, then for gradually releasing the totality of the active principle within the following 8 to 20 hours. The invention is characterised in that it is free of organic acid and it is in the form of medicated spheroids consisting of a neutral spherical carrier comprising a first coating based on a mixture of at least a water soluble polymer and at least a water insoluble polymer wherein are uniformly distributed particles constituting an active principle, the whole comprising a second coating based on at least two independent pH polymers, having degrees of permeability with respect to different gastric and intestinal environments, optionally at least a dependent pH polymer, at least a plasticising agent and at least an inert filler distributed in said coating.
