    摘要： The invention relates to a novel diffusion-osmotic controlled drug-release pharmaceutical composition containing a one-layer tablet core including a polymeric film-coat, a therapeutically active agent and a hydrophilic polymer; if desired, a two-layer tablet core including active agent and hydrophilic polymer in the first layer thereof and a hydrophilic polymer in the second layer thereof; at least one bore on the part of film-coat in contact with the core or core layer containing the active agent; and, if desired, containing one or more bore(s) in the part thereof in contact with the second layer containing the hydrophilic polymer, which comprises an ammonium methacrylate copolymer as coating material and hydroxypropyl-methylcellulose as hydrophilic polymer. The composition according to the invention is useful for preparing controlled drug-release tablets containing as active agents e.g. .beta.-adrenergic inhibitors (e.g. propranolol) calcium-antagonists (e.g. nifedipine), angiotensin convertase enzyme (ACE) inhibitors (e.g. captopril); prazosin; or nitroglycerol, all used in heart and circulation diseases; vasodilatory active agents (e.g. pentoxyfylline), nonsteroidal antiinflammatory agents (e.g. naproxene), analgetic drugs (e.g. morphine) and drugs acting on the central nervous system (e.g. amitriptyline, buspiron). The invention furthermore relates to a process for the preparation of the above compositions.

    摘要： The invention provides a method for preparing sustained release tablets comprising a hydrophilic polymer matrix, which amounts to at least 10% by weight of the composition, consisting of a 5:1-1:5 weight to weight ratio mixture of a VP-VA copolymer and of an acrylic acid homopolymer, cross-linked with polyallyl saccharose.The method of manufacturing of sustained release tablets according to the invention can be accomplished in two ways: either by manufacturing the granulate containing the active ingredient, or by supplementing the matrix granulate containing no active ingredient with the suitable amount of the active ingredient.The latter variant involves the advantage of a possible separation of large-scale manufacturing of pharmacons and that of a generally applicable retardizing system, the composition and, consequently, the retardizing ability of which can optionally be modified in accordance with the properties of the active ingredient(s) to be formulated.
