Pharmaceutical dosage forms comprising an active ingredient combination of nifedipine and/or nisoldipine and an angiotensin II antagonist
First Claim
1. A pharmaceutical dosage form on the basis of an osmotic active ingredient release system, comprising a core and a semipermeable membrane which surrounds the core, wherein the core comprises an active ingredient combination of nifedipine or nisoldipine and at least one angiotensin II antagonist, wherein the semipermeable membrane is water-permeable but substantially impermeable to components of the core, and the semipermeable membrate includes at least one orifice, and wherein the release rates of the active ingredients differ from one another by no more than 25% absolute in the linear part of a release profile in a USB release method with apparatus 2 (paddle).
