  • Patent number: 7438929
    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: 20060204576
    Abstract: The invention relates to a multilayer dosage form comprised of: a) a neutral core; b) an inner coating consisting of a methacrylate copolymer; c) an outer coating consisting of a copolymer of which 40 to 95% by weight is composed of radically polymerized C1 to C4 alkyl esters of acrylic acid or of methacrylic acid and of which 5 to 60% by weight is composed of (meth)acrylate monomers having an anionic group in the alkyl radical. The invention is characterized in that the inner coating is essentially comprised of a methacrylate copolymer, of which at least up to 90% by weight consists of (meth)acrylate monomers with neutral radicals, which, in accordance with DIN 53 787, has a minimum film formation temperature of no higher than 30° C., and which contains the pharmaceutical active substance in bound 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%.

  • Publication number: 20030117633
    Abstract: A measuring device that employs interference optics for detecting and tracking the movement of a mechanical element (4) has a light source (31) for emitting a light bundle that is capable of interference, a diffraction grating and a sensor arrangement (33). A beam path leads from the light source to the sensor arrangement (33) by way of the diffraction grating (32). The diffraction grating divides the light bundle into at least three partial components, thereby forming a light patch having three overlapping maxima, the center, zero maximum and the two minus one and plus one maxima on either side, at the optical sensor arrangement (33). The light beams for generating the three brightness maxima interfere with one another, so the resulting superposed light patch (46) contains interference bands that run in one direction or another when the diffraction grating is moved. The movement of the interference bands is detected with the sensor arrangement (33), and evaluated in an evaluation circuit.
