Patent ID: 6897205

Claim:
A multiparticulate drug form comprising at least pellet form A and pellet form B, wherein each of said pellet forms comprises an active pharmaceutical ingredient and at least one polymer coating, wherein the polymer coating of pellet form A is different from the polymer coating of pellet form B, wherein pellet form A comprises an inner polymer coating and an outer enteric coating which rapidly dissolves above about pH 5.5, and pellet form B comprises a different polymer coating which, in the USP release test, releases less than 20% of the active pharmaceutical ingredient at pH 6.8 in 6 hours and releases more than 50% of the active pharmaceutical ingredient at pH 7.2 in 6 hours, wherein said multiparticulate drug form is capable of uniformly releasing the active pharmaceutical ingredient in the small intestine and large intestine, and wherein the polymer coating of pellet form A and pellet form B determines the release of the active pharmaceutical ingredient at different pH, wherein the active pharmaceutical ingredient is an aminosalicylate, a sulphonamide, a hormone, a peptide, an interferon, or a glucocorticoid.
