Claims
- 1. A medicinal formulation in the form of tablets, granulates or pellets containing an active ingredient selected from the group consisting of mesna and flupirtine maleate, and having an active ingredient content of more than 45% by weight, said granulate or the granulate used to produce said tablets being produced by intensive moistening of said active ingredient with more than 30 weight % water, relative to the amount of solid substance used, the active ingredient being repeatedly moistened with maximum energy input in a qranulator, and subsequently dried at a temperature between 20.degree. C. and 50.degree. C.
- 2. A medicinal formulation in the form of tablets, granulates or pellets as set forth in claim 1 in which the active ingredient content is more than 75 weight %.
- 3. A medicinal formulation in the form of tablets, granulates or pellets as set forth in claim 2 in which the active ingredient content is more than 85 weight %.
- 4. A process for the preparation of granulate or pellets which comprises granulating or pelleting at least one pharmaceutically active ingredient or a mixture of at least one active ingredient and at least one auxiliary substance with more than 30 weight % of water, relative to the amount of solid substances used, with maximum energy input, wherein the active ingredient or ingredients are selected from the group consisting of mesna and flupirtine maleate.
- 5. A medicinal formulation in the form of tablets, granulates or pellets containing mesna, said granulate or the granulate used to produce the tablets being produced by intensive moistening of mesna with more than 30 weight % water, relative to the amount of solid substances used.
- 6. A medicinal formulation in the form of tablets, granulates or pellets containing the maleate of 2-amino-3-ethoxycarbonyl-amino-6-(4-fluoro)-benzylamino ridine, said granulate or the granulate used to produce the tablets being produced by intensive moistening of the maleate of 2-amino-3-ethoxycarbonyl-amino-6-(4-fluoro)-benzylamino pyridine with more than 30 weight % water, relative to the amount of solid substances used.
- 7. A process for the preparation of a medicinal formulation as set forth in any one of claims 1-3 which comprises repeatedly moistening the active ingredient, with maximum energy input in a granulator with more than 15 weight % water, and subsequently drying at temperatures between 20.degree. C. and 50.degree. C.
- 8. A process as set forth in claim 7 including processing the granulate into pellets or tablets.
- 9. A process as set forth in claim 4 including the step of converting the granulate or pellets thus obtained into tablets.
- 10. A process according to claim 7 in which the active ingredient is mesna.
- 11. A process according to claim 7 in which the active ingredient is flupirtine maleate.
- 12. A process as set forth in claim 7 in which the amount of water is more than 30 weight %.
- 13. A medicinal formulation in the form of granulate bodies or pellets produced by a process in which the active ingredient or the mixture of active ingredients and auxiliary substances are granulated at least once with more than 30 weight % water relative to the dry weight of the solid substance and with maximum energy input in a granulator and subsequently dried at a temperature between 20.degree. C. and 50.degree. C., wherein the active ingredient or ingredients are selected from the group consisting of mesna and flupirtine maleate.
