Abstract: The present invention relates to a method for the reliable and reproducible preparation of 4-[17?-methoxy-17?-methoxymethyl-3-oxoestra-4,9-dien-11?-yl]benzaldehyde (E)-oxime (asoprisnil) on the pilot and manufacturing scale. Asoprisnil, which is prepared by this method, is distinguished by a very good physical stability and is therefore particularly suitable for the manufacture of solid pharmaceutical forms (tablets, coated tablets, etc.).

Abstract: The peroral medication for prevention of conception contains as one active ingredient crystalline 17?-cyanomethyl-17?-hydroxyestra-4,9-dien-3-one (dienogest) at a daily dosage equal to or less than 2.0 mg and as another active ingredient 17?-ethinyl estradiol at a daily dosage of less than 0.030 mg, together with one or more pharmaceutically acceptable carriers. The active ingredient dienogest is contained in the medication in crystalline form with an average particle size of preferably 25 to 70 ?m. The other active ingredient ethinyl estradiol is incorporated during granulation in micronized form or by spraying an ethanolic solution containing it.

Abstract: The process for making crystals of a 11 ?-benzaldoxim-estra-4,9-diene derivative having an average particle size of from 3 ?m to 25 ?m and a maximum particle size of 100 ?m, includes subjecting a supersaturated solution containing a special 11?-benzaldoxim-estra-4,9-diene derivative of formula (I) to a wet milling by a wet milling apparatus while crystallizing, In order to obtain a primary particle suspension. Crystals obtained according to this process and pharmaceutical preparations containing them are also described and are part of the invention.

Abstract: The invention relates to a transdermal therapeutic system for application to the skin and/or mucosa consisting of at least one active substance in the form of a solid dispersion in combination with at least one destructuring agent and/or at least one structuring agent in a common matrix.

Abstract: This invention relates to an in-situ implant that can be produced by placing a sterile, injectable, and water-insoluble complex from a biodegradable polymer and a biocompatible polyether with functional end-groups in the organism, and coagulating them under the influence of the body fluid. This coagulate may optionally contain at least one bioactive substance selected from the group of hormones, immunomodulators, immunosuppressants, antibiotics, cytostatics, diuretics, gastro-intestinal agents, analgesics, local anaesthetics and/or neuropharmacological agents.

Abstract: The method of making a solid drug with controlled effective ingredient delivery for oral administration includes selecting a predetermined number of at least three of four compressed compositions containing an effective ingredient or effective ingredient combination defined by their release profile of effective ingredient and/or effective ingredient combination. The solid drug or medicinal preparation is formed according to known methods requiring only comparatively small apparatus expense and minimal time. Perorally administered solid drugs are made by this process which can provide widely varying pharmaceutically-required release profiles of effective ingredients or effective ingredient combinations, for example delayed release, uniformly maintained release or pulsatile release adjusted to fit a special rhythm.
