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 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.
