Pharmaceutical preparation with retarding active ingredient release, method for its production and its use
The invention describes pharmaceutical preparations with retarding active ingredient release, which consist of mixtures of powdery teicoplanin and at least one powdery, water soluble salt form of gentamicin, clindamycin, kanamycin, amikacin, tobramycin, vancomycin, moxifloxacin and ciprofloxacin and an inorganic and/or organic adjuvant. The pharmaceutical preparations are used as permanent or as temporary implants in the form of tablets, molded bodies, fibers and granules.
1. A dry pharmaceutical preparation comprising a dry mixture of powdery teicoplanin and at least one powdery, water soluble salt form of at least one of gentamicin, clindamycin, kanamycin, amikacin, tobramycin, vancomycin, moxifloxacin and ciprofloxacin and an inorganic and/or organic adjuvant.
2. The dry pharmaceutical preparation pursuant to claim 1 , which contains calcium carbonate, calcium sulfate dihydrate, tricalcium phosphate and/or hydroxylapatite as the inorganic adjuvant.
3. The dry pharmaceutical preparation pursuant to claim 1 , which contains polyesters of at least one of lactic acid, glycolic acid, 5-hydroxy valerie acid, 6-hydroxy caproic acid and co-polymers thereof as organic adjuvants.
4. The dry pharmaceutical preparation pursuant to claim 1 , which is in the form of one of tablets, molded bodies, fibers and granules.
5. The dry pharmaceutical preparation pursuant to claim 1 , comprising a combination of polymerizable methacrylic acid esters and mixtures consisting of powdery teicoplanin and at least one powdery, water soluble salt form of at least one of gentamicin, clindamycin, kanamycin, amikacin, tobramycin, vancomycin, moxifloxacin and ciprofloxacin formed and polymerized into a molded body.
6. The dry pharmaceutical preparation pursuant to claim 1 , wherein the mixture is part of a resorbable and/or of non-resorbable coating, which has been applied to non-metallic and metallic implants.
7. The dry pharmaceutical preparation pursuant to claim 1 , wherein before being cured inorganic calcium phosphate bone cements and plaster mixtures are admixed to mixtures consisting of powdery teicoplanin and at least one powdery, water soluble salt form of at least one of gentamicin, clindamycin, kanamycin, amikacin, tobramycin, vancomycin, moxifloxacin and/or ciprofloxacin.
8. A permanent or temporary implant comprising a dry pharmaceutical preparation pursuant to claim 1 in the form of one of tablets, molded bodies, fibers and granules.
9. A method of treating a bacterial infection in a patient in need thereof comprising administering to said patient a pharmaceutical preparation pursuant to claim 1 .
10. A method of preparing the dry pharmaceutical preparation according to claim 1 , said method comprising dry mixing powdery teicoplanin and at least one powdery, water soluble salt form of at least one of gentamicin, clindamycin, kanamycin, amikacin, tobramycin, vancomycin, moxifloxacin and ciprofloxacin and an inorganic and/or organic adjuvant.
