Abstract
The invention provides a gastric resistant, enteric-coated solid dosage form including a core containing a pharmaceutically active ingredient, an inner coating for the core, and an outer enteric coating. The inner coating comprises an anionic polymeric material or a water-soluble neutral polymeric material, and further comprises a water soluble inorganic salt which is not a carbonate or bicarbonates. The outer enteric coating comprises an anionic polymeric material which is less neutralized than the polymeric material comprising the inner coating and disintegrates rapidly at a pH of 5.5 to 7.0 upon entering the small intestine.
