  • Patent number: 6897205
    Abstract: The invention relates to a multiparticulate drug form suitable for uniform release of an active pharmaceutical ingredient in the small intestine and in the large intestine, comprising at least two forms of pellets A and B which comprise an active pharmaceutical ingredient in the core and have different polymer coatings which determine the release of the active ingredient at different pH values, characterized in that pellet form A is provided with an inner polymer coating which enables continuous release of active ingredient, and has an outer enteric coating which rapidly dissolves above about pH 5.5, and pellet form B is provided with a polymer coating which, in the USP release test, releases less than 20% of the active ingredient at pH 6.8 in 6 hours and releases more than 50% of the active ingredient at pH 7.2 in 6 hours. The invention additionally relates to a process for producing the multiparticulate drug form and to the use of pellet forms A and B for producing the drug form.

  • Publication number: 20050089571
    Abstract: The invention relates to a pharmaceutical formulation containing essentially a) an inner layer which can optionally be applied to a core, with the active substance budesonide, bound with a binding agent; b) a middle layer with a polymer covering agent which is soluble in intestinal juice or retardant; and c) an outer envelope or outer layer which is resistant to stomach juice, said layers being able to contain in a manner known per se other pharmaceutically usual adjutants. The inventive formulation is characterised in that the binding agent is a polymer or a copolymer with acid groups and the formulation of the inner layer without the middle and outer layer releases the bound active ingredient in a release test according to USP XXIII monography <711> dissolution with apparatus 2 (addle) at a rotational speed of 100/min in a phosphate buffer pH 7.5 after 30 min to a value of more than 80%.
