Abstract[English]
The invention relates to pharmaceutical dosage forms comprising a drug having a fast absorption in the gut, which is absorbed in distal intestinal tract including the colon, and for which pulsatile release is necessary to avoid the potential toxicity of the drug continuous absorption. In particular the invention is directed to a dosage form comprising a formulation in form of coated small units to deliver the active ingredient after a programmed time period following oral administration and processes of preparation thereof. In a preferred embodiment the drug is the iron chelator deferiprone.[French]
