Delayed release pharmaceutical formulations |
| abstract |
In a delayed release formulation comprising a drug-containing core and a delayed release coating for enteral release, the release of the drug in the colon is accelerated by the inclusion of a barrier layer between the core and the delayed release coating. The delayed release coat includes an inner layer and an outer layer. The outer layer comprises a pH-dependent soluble polymeric material having a pH threshold of about pH 5 or above. The inner layer comprises a soluble polymeric material that is soluble in intestinal or gastrointestinal fluids, the soluble polymeric material being selected from at least partially neutralized polycarboxylic acid polymers and nonionic polymers, provided that when the soluble polymer is When the material is a non-ionic polymer, the inner layer contains at least one additive selected from buffers and bases. |
