Pressing containing homo- and/or copolymers of D(-)-3-hydroxybutyric acid, at least one solid disintegrant and at least one solid pharmaceutical active compound, process for its production and the use of homo- and/or copolymers of D(-)-3-hydroxybutyric acid for the production of such a pressing.

Pressing not delayed release of active compound, process for its

Delayed-release tablets are formed by incorporating hemicellulose and a matrix-forming adjuvant which does not disintegrate in a pharmaceutical dosage form containing the active substance or substances, preferably as a coated tablet or dragee.

Delayed-release pharmaceutical preparation

Pressing having sustained release of active compound for the oral or parenteral administration of medicaments, which contains at least one solid pharmaceutical active compound, polylactic acid and a homo- or copolymer of D(-)-3-hydroxybutyric acid and processes for its production.

Pressing having sustained release of active compound

Binder-free granules for oral and parenteral administration with delayed release of the active compound, consisting of a pharmaceutical active compound or granules thereof and a coating of 1 to 20% by weight of poly-D(-)-3-hydroxybutyric acid, based on the total weight, and a process for their preparation.

Binder-free granules with delayed release of the active compound

Pharmaceutical composition for long-term oral or parenteral administration and adapted to slowly release the pharmaceutically active substance, comprising a therapeutically-active amount of a pharmaceutically-active substance homogeneously mixed with at least 20% by weight of poly-D(-)-3-hydroxybutyric acid relative to the amount of active substance; a process for preparing such composition in compressed form and a process for the long-term administration of such composition.
