Abstract:
The present invention relates to novel pharmaceutical formulations which have controlled, delayed release of active ingredient, and to a process for the preparation of such formulations. The invention additionally relates to the use of these novel pharmaceutical administration forms as medicaments for the treatment of diseases which require delayed release of the active ingredient, such as hypertension, or asthmatic diseases.

Claim (Index 1):
Process for the preparation of a pharmaceutical administration form of a composition having extended release of active ingredient, characterised in that\n a) a polyvinyl alcohol which has been approved for use in pharmaceutical formulations is ground at low temperatures in the range from minus 30\u00b0 C. to 0\u00b0 C. to give a finely divided powder having an average particle size Dv50 in the range 50-100 \u03bcm, preferably in the range Dv50 60-95 \u03bcm, and is sieved through an 800 \u03bcm sieve, and b) mixed intensively with microcrystalline cellulose having an average particle size Dv50 in the range 100 to 150 \u03bcm, c) this mixture is mixed with an adequate amount of the active ingredient, e) additives which are advantageous for further processing, such as flow-control agents or lubricants, are optionally added and f) after adequate mixing of the resultant mixture and optionally after sieving in order to remove coarse particulate material still present, the mixture is tabletted by compression at a suitable pressure.
