Abstract
The present invention is directed to a delayed release pharmaceutical composition in solid dosage form comprising a core comprised of a therapeutically effective amount of drug, e.g., mesalamine, and a pH sensitive coating comprising a mixture of two different pH sensitive polymers, the first pH sensitive polymer dissolves in an aqueous solution at a pH of about 7 or greater and the second pH sensitive polymer dissolves in an aqueous solution at a pH of about 6 or greater, wherein the weight ratio of the first pH sensitive polymer to the second pH sensitive polymer ranges from about 2:1 to about 4:1 and the percent weight gain resulting from the addition of the pH sensitive coating ranges from about 8% up to and including 15% by weight of the core, including any subcoating.
