Definitions

  • glycosaminoglycans for the manufacture of pharmaceutical preparations for the treatment of eye diseases associated with diabetes
  • the invention relates to the use of glycosaminoglycans for the production of pharmaceutical preparations for the prevention or treatment of eye diseases associated with diabetes mellitus.
  • the invention further relates to pharmaceutical preparations suitable for the treatment of diabetes-associated eye diseases.
  • glycosaminoglycans and especially heparins and heparinoids for the manufacture of pharmaceutical preparations for the treatment of circulatory disorders is well known.
  • glycosaminoglycans in a number of other diseases has recently been described.
  • No. 5,236,910 claims the use of glycosaminoglycans in the treatment of diabetic nephropathy and neuropathy.
  • the use of low molecular weight heparins for the same indication is described by van der Pijl et al. (J. Americ. Soc. Nephrol. 1997, 8: 456-462).
  • Retinopathy is the most common and serious eye complication in diabetes mellitus. It is the main cause of blindness in industrialized countries. The risk of going blind is very difficult to assess in an individual diabetic. It depends on many factors such as age, type and duration of the diabetes. The current retina findings also play an important role in assessing the risk.
  • retinopathy The prevalence for retinopathy was 50.1% within the study patients, but only 2.2% had features at risk of loss of vision. In the "younger" group, the prevalence of moderate visual impairment was 1.4%. 3.2% were blind.
  • the disadvantage of this method is that the detoxified enzyme must first be obtained from the snake venom in a complex process and then detoxified. Only in combination with high-molecular heparin could animal retinopathy be treated with guinea pigs. Neither the heparin used nor the snake enzyme alone showed an effect in the treatment of retinopathy.
  • the object was therefore to provide agents for the treatment of retinopathy and / or macular degeneration which do not have the disadvantages mentioned above and can be used safely, easily and simply for the treatment of retinopathy and macular degeneration.
  • glycosaminoglycans for the production of pharmaceutical preparations for the prevention or treatment of eye diseases associated with diabetes.
  • the invention also relates to pharmaceutical preparations containing one or more substances selected from the group consisting of glycosaminoglycan, glycosaminoglycan derivatives, heparinoids, physiologically active salts of these substances or mixtures thereof, which are suitable for the treatment of " diabetes-associated eye diseases " .
  • the pharmaceutical preparations produced for the use according to the invention can contain the abovementioned compounds as free compounds, or in the form of their physiologically active salts, their tautomeric and / or isomeric forms or in the form of the combination of the free compounds and the various salts.
  • the Na, Ca or Mg salts may be mentioned as examples of advantageous physiologically active salts. Salts with organic bases such as diethylamine, triethylamine or triethanolamine are also suitable.
  • the pharmaceutical preparations can advantageously contain at least one free substance or at least one compound in the form of its salt or mixtures thereof.
  • uronic acid such as D-glucuronic acid or L -Iduronic acid
  • At least one of the sugars in the disaccharide has a negatively charged carboxylate or sulfate group, which can be bonded via an oxygen or nitrogen atom.
  • glycosaminoglycans react strongly acidic. These acid-reacting groups can be naturally present and / or synthetically introduced into the compounds by, for example, sulfation.
  • An example of a sulfation method is US 5,013,724.
  • Examples of natural glycosaminoglycans are heparin, heparan sulfate, keratin sulfate, dermatan sulfate, chondroitin or chondroitin sulfate. Heparan sulfate corresponds to heparin, only that it has fewer N and 0 sulfate groups and more N acetyl groups.
  • glycosaminoglycans or heparinoids are advantageously selected from the group dermatan sulfate, heparan sulfate, dextran sulfate (US 5,541,166), xylan sulfate (such as pentosan polysulfate, EP-A-0 184 480, FR 835170), Heparin or derivatives of these substances are used. These substances are applied in an effective amount for the treatment of eye diseases.
  • Glycosaminoglycans can advantageously be isolated from tissues of animals such as the intestinal mucosa or from the ears of pigs or cattle.
  • the tissues used are, for example, autolyzed to isolate the glycosaminoglycans and extracted with alkali.
  • the protein is then left to coagulate and is precisioned, for example by acidification.
  • the precipitate has been taken up in a polar, non-aqueous solvent, such as ethanol or acetone, the fats are removed by extraction with an organic solvent.
  • the proteins are finally removed by proteolytic digestion and the glycosaminoglycans are thus obtained. Charles et al. (Biochem. J., Vol.
  • Coyne, E in Chemistry and Biology of Heparin (Elsevier Publishers, North Holland, NY, Lunblad, RL, eds., 1981) are methods of isolating, for example To take heparin.
  • glycosaminoglycans isolated from natural sources can advantageously also undergo derivatization, for example by polysulfation, as is described, for example, in US Pat. No. 5,013,724.
  • the glycosaminoglycans have a sulfur content of 6 to 15% by weight, preferably between 13 to 15% by weight.
  • Derivatives of the substances are to be understood as compounds which improve the application properties of the glycosaminoglycans used in terms of their action, their stability and their elimination from the body.
  • Low molecular weight heparins and / or dermatan sulfates, which can be polysulfated, in the form of the free acid or in the form of a salt with physiologically compatible bases or mixtures of these compounds are particularly advantageous.
  • Low molecular weight glycosaminoglycans for example low molecular weight heparins and / or dermatan sulfates, can be produced by a number of methods. The production of low molecular weight heparins via depolymerization using nitrous acid is described, for example, in EP-B-0 037 319 or in Biochemistry Vol. 15, 1976: 3932. Low molecular weight heparin or low molecular weight glycosaminoglycans can also be produced with enzymes (Biochem. J. Vol. 108, 1968: 647), with sulfuric acid and chlorosulfonic acid (FR No.

  • blood pressure lowering agents are, for example
  • inhibitors of the endothelin converting enzyme ECE
  • endothelin antagonists or inhibitors of the renin-angiotensin system or a combination thereof.
  • Inhibitors of the renin-angiotensin system are renin inhibitors, angiotensin II antagonists and, above all, angiotensin converting enzyme (ACE) inhibitors.
  • ACE angiotensin converting enzyme
  • Blood sugar-lowering active substances are understood to mean, for example, insulin, blood sugar-lowering agents for oral use, such as sulfonylureas or glucosidase inhibitors.
  • the combinations of the active substances mentioned can be administered in a common galenical form or in a time and space separate manner.
