Definitions
- the invention relates to polysaccharides crosslinked with bifunctional crosslinking agents, a process for their preparation, their use for coating and embedding medicaments and medicaments coated and embedded with them.
- the oral dosage form is a preferred administration of drugs.
- Medicines that only work in the large intestine e.g. Those which are used for chronic colon inflammation or Crohn's disease and medicaments which are normally broken down or digested under the physiological conditions in the stomach or in the small intestine must be protected so that they remain unchanged in the large intestine.
- Medicinal substances which are broken down or digested in the small intestine include, for example, the peptide medicinal substances.
- the present invention is based on the object of providing crosslinked polysaccharides, processes for their preparation, their use and medicaments with which a protected transport of medicinal products through the stomach and small intestine with subsequent targeted release of the medicinal product in the large intestine is possible.
- the local application of drugs into the large intestine for example in the case of chronic colon inflammation or Morbus Crohn, and of active ingredients which are normally broken down or digested under the physiological conditions in the stomach or small intestine should be possible.
- the aim of the present invention is to open up the development of new small intestine-resistant, but colon-degradable Kilfss * cof £ e for the large intestine tarcetin ⁇ .
- the applicant has found that the low microbial colonization of the distal sections of the small intestine, in comparison to the well-developed microflora in the caecum, is particularly suitable for developing substances by which the stated object can be achieved.
- the invention relates to polysaccharides crosslinked with bifunctional crosslinking agents, which are no longer water-soluble but are still biodegradable, have a swelling of between 100 and 1,000%, the swelling, which means weight gain in percent, being determined by the following equation:
- A is the weight increase in percent
- G 0 is the weight of the dry polymer
- G t is the weight of the swollen, water-saturated polymer.
- the invention further relates to a process for the production of the crosslinked polysaccharides, according to which a polysaccharide with a molecular weight of 100,000 to 10 million is used, namely: Galactomannans: 100,000-1 million, preferably 500,000-1 million
- Laminarin 100,000-1 million, preferably 500,000-1 million
- Glucomannan 100,000-1 million, preferably 500,000-1 million
- Dextran 100,000-10 million, preferably 1 million-10 million
- Pectins 100,000 - 500,000
- the suspension suspended in an aliphatic diglycidyl ether, a C 1 -C aliphatic dicarboxylic acid or its reactive derivative or a C 1 -C 10 aliphatic dialdehyde, optionally with the addition of an inert organic solvent or swelling agent, the suspension to a temperature in the Heated range from room temperature to 80 ° C, to which the suspension adds a catalytic amount of a base, the reaction mixture is stirred at the temperature mentioned for a period of 1 to 15 hours and then the cross-linked polysaccharide in a manner known per se separated and optionally washed one or more times with water, methanol or acetone.
- the invention also relates to the use of the crosslinked polysaccharides for coating and / or embedding active pharmaceutical ingredients or pharmaceutical preparations and a pharmaceutical composition which envelops or embeds an active ingredient acting in the large intestine or an active ingredient which is broken down when it passes through the stomach or small intestine in one of the cross-linked polysaccharides.
- crosslinked polysaccharides which are decomposed in the uncrosslinked state by the glycosidases of the colon microflora and which have been crosslinked with bifunctional crosslinking agents in such a way that they are no longer water-soluble but are still biodegradable. cash, meet the requirements mentioned. If the derivatization is too extensive, the degradability is lost. Accordingly, the polysaccharide may only be changed according to the invention in such a way that water solubility is prevented. For this purpose, the polysaccharides are crosslinked with suitable crosslinking agents. It should be noted that small crosslinking tents and the use of long-chain crosslinking agents result in correspondingly loose networks into which the enzyme can penetrate and enzymatically break down the film.
- polysaccharides listed in the following table can be used as starting points for the crosslinking.
- Laminarin (l, 3) -ß-glucose +++ exoenzy degradation products oligosaccharides
- Dextran branched glucans +++ exoenzyme / ⁇ -1,6-D-glucose, endoenzyme ⁇ -l, 3-glucose (branched)
- the polysaccharides used according to the invention have a molecular weight of 100,000 to 10 million.
- the molecular weight is not particularly critical as long as the abovementioned conditions are met, that is to say that the polysaccharides in the uncrosslinked state are broken down by the glycosidase of the colon microflora and are no longer water-soluble after crosslinking.
- the preferred and particularly preferred molecular weights for some of the polysaccharides are given below.
- Galactomannans 100,000-1 million, preferably 500,000-1 million
- Laminarin 100,000-1 million, preferably 500,000-1 million
- Glucomannan 100,000-1 million, preferably 500,000-1 million
- Dextran 100,000-10 million, preferably 1 million-10 million
- Pectins 100,000 - 500,000
- the appropriate polysaccharides are broken down by enzymes.
- the endoenzyme (1,4) -ß-mannase is proven to be produced by the human colon flora.
- the bacterial genus Bacteroides which produces an exo / endoenzyme system, which breaks down ⁇ -1,6-glycosidic bonds, such as those present in dextran, is still abundant in the human colon. This explains why the colon microflora can not only cleave ß-1,4- but also ⁇ -1,6-glycosidic bonds.
- the polysaccharides used according to the invention are not attacked by amylases and are therefore stable in the small intestine.
- Crosslinked polysaccharides which are cleaved by endoenzymes are preferably used.
- the endoenzymes split the polysaccharides inside and relatively quickly, which releases the active ingredient immediately. The cleavage takes place more slowly with the exogenous enzymes that attack the end of the polysaccharides.
- polysaccharides mentioned are not suitable in uncrosslinked form as a film coating or embedding material, since they are water-soluble and dissolve and degrade too quickly. They are therefore networked according to the invention.
- Various reagents can be used according to the invention as crosslinking agents. Those crosslinking agents which have already been used pharmacologically and have been regarded as harmless are preferably used.
- the crosslinking agents must be bifunctional, and examples are: aliphatic diglycidyl ethers such as 1,4-butanediol diglycidyl ether or 1,6-hexanediol diglycidyl ether, Dicarboxylic acids such as succinic acid, glutaric acid, adipic acid or their reactive derivatives such as the acid dichlorides or anhydrides, C 4 -C 10 aliphatic dialdehydes such as glutardialdehyde, succinic dialdehyde or adipic dialdehyde.
- 1,4-butanediol diglycidyl ether 1,6-hexanediol diglycidyl ether, adipic acid, adipic acid dichloride and adipic acid dialdehyde are preferred.
- the crosslinking agents react with the OH groups of the polysaccharides, and the crosslinking product thus obtained is insoluble in water, but swellable and dispersible in water and forms good quality films.
- the water absorption of the cross-linked polysaccharide i.e. the swelling of the crosslinked polysaccharide is used for characterization.
- the crosslinked polysaccharides according to the invention have a swelling of between 100 and 1,000%, preferably between 150 and 850%.
- the swelling is determined by weighing 100 mg of the crosslinked polysaccharides in the form of the polymer films into an ampoule and adding 10 ml of water. After 1, 5, 8, 20, 48 and 73 hours the film is removed from the water and blotted onto cellulose and weighed.
- the weight gain can be calculated using the following formula:
- the swelling depends to a small extent on the crosslinking agent. As stated above, it is generally in the range between 100 and 1,000%. If the diepoxides are used, they are between 100% and 800%, preferably 200 to 400%. If dicarboxylic acids, their reactive derivatives and dialdehydes are used, the swelling is between 150 and 850%, preferably between 200 and 550%.
- the person skilled in the art can easily determine by suitable preliminary tests which quantitative ratios between the uncrosslinked polysaccharide and the crosslinking agent have to be used and whether the crosslinked polymer obtained has the properties according to the invention. In the following, the conditions for crosslinking with diepoxides and with dicarboxylic acids and dialdehydes are given.
- the following molar ratios must be observed.
- the molar ratios are based on the primary and secondary OH groups of the sugar units.
- the products formed during crosslinking can be characterized by their swelling and stability in water and by their degradability by hemicellulases. Too little cross-linked polysaccharides show too strong swellings or the films disintegrate. Polysaccharides that are too strongly cross-linked can no longer be broken down by the corresponding enzymes. given ratios are molar ratios.
- crosslinking products that swell between 100% and 800%, preferably 200 to 400%, are degraded by hemicellulases. These crosslinking products are preferred when using C 4 -C 10 -alkanediol diglycidyl ethers.
- DiCbscl dicarboxylic acid chloride
- 4-DMAP 4-dimethylaminop ⁇ -ridine
- DCC dicyclohexylcarbodiimide
- the most important characteristic is the swelling of the cross-linked products and the enzymatic degradability.
- a strong ester band can be seen at 1740 in the IR.
- the films obtained from the crosslinked polysaccharides are insoluble in water, but have different degrees of swelling in water depending on the degree of crosslinking.
- the invention also relates to a method for producing the new crosslinked polysaccharides as stated above.
- the polysaccharide with the molecular weight indicated above is suspended in the crosslinking agent as indicated, optionally with the addition of an inert solvent or swelling agent such as an aliphatic alcohol. It is preferred to work without solvents.
- the suspension obtained is heated to a temperature in the range from room temperature to 80 ° C., preferably to 60 ° C., with stirring. The temperature must not be chosen so high that lumps form from the polysaccharide.
- a catalytic amount of a base is added to the suspension.
- the type of base is not particularly important, and alkali metal hydroxides such as sodium hydroxide or potassium hydroxide, alkali metal carbonates or organic bases such as 4-dimethylaminopyridine are generally used.
- the reaction mixture is then preferably at room temperature or at a temperature up to 80 ° C to 60 ° C, particularly preferably to 40 ° C, for a period of 1 to 15 hours, preferably 1 to 6 hours, stirred.
- the cross-linked polysaccharide is then separated off in a manner known per se, for example by centrifugation, filtration, etc. For cleaning, it is washed with water one or more times in a manner known per se.
- the product is dried and can then be used directly.
- novel crosslinked polysaccharides according to the invention can be used to coat or embed active pharmaceutical ingredients or pharmaceutical preparations which are to be used locally in the large intestine, or to protect active ingredients which are normally broken down or digested in the small intestine or stomach under the physiological conditions, or else for the production of films containing these active pharmaceutical ingredients or pharmaceutical preparations. In such cases, the corresponding active pharmaceutical ingredients have generally had to be administered parenterally.
- polysaccharides crosslinked according to the invention can be synthesized in one synthesis step, survive the gastrointestinal tract undamaged and can be rapidly broken down in the large intestine.
- the invention thus furthermore relates to the use of the crosslinked polysaccharides according to the invention for the production of film coatings and embedding of pharmaceutical active substances which can be administered orally and in which active substance releases are to take place in the colon.
- the active pharmaceutical ingredients or pharmaceutical preparations are coated with and / or embedded in the crosslinked polysaccharides according to the invention.
- the wrapping or embedding is carried out according to methods known per se, for example for wrappings in Bauer, Lehmann, Osterwald, Rothgang: gene dosage forms, Wiss. Publishing company Stuttgart, 1988, and for embedding in Bauer, Frömming, 5.3: Pharmaceut. praxis, 3rd edition, G. Thieme Verlag Stuttgart, 1991, pages 278, 353 and 358.
- granules, pellets, tablets, etc. can be produced in a manner known per se.
- the active substances which can preferably be formulated with the crosslinked polysaccharides according to the invention are, for example, those active pharmaceutical substances which have been broken down or digested in the stomach or small intestine and therefore have not been administered orally in the past, and medicaments which have only been used are said to act in the colon, such as drugs that work against colon diseases and peptide drugs.
- examples are: peptides, cardiovascular therapeutics, anti-inflammatory drugs / analgesics, agents for the treatment of colon diseases such as Crohn's disease and ulcerative colitis, anti-asthmatics, anti-fibrinolytics, anti-hemorrhaging agents, anti-tumor agents, enzyme preparations, antibiotics, anti-mycotics, substances with an effect on the Central nervous system.
- peptide active ingredients are: ACTH (adrenocorticropical hormone), corticostatin, calcitonin, insulin, oxytocin, somatostatin and analogs, LHRH analogs, bombesin analogs, cholecystokinin and derivatives, endothelin and analogs, thrombin inhibitors, peptide growth factors (e.g.
- ANP atrial natriuretic peptide
- biotechnologically produced peptides in particular low peptides.
- the crosslinked galactomannan thus obtained can be dispersed in water using an Ultraturrax. Good quality films can be produced from such aqueous dispersions.
- the minimum film formation temperature is approx. 50 ° C, the degree of swelling is 400 to 600%.
