The invention relates to synchronous drug delivery composition comprising a polymeric matrix which comprises hydrogel blended with a hydrophobic polymer, so as to form an erodible matrix, a drug, and, optionally, an agent which enhances intestinal drug absorption and/or an agent which inhibits intestinal drug degradation,wherein erosion of the erodible matrix, permits synchronous release of the drug, the hydrogel and the intestinal drug absorption agent and/or the agent which inhibits intestinal drug degradation.
