Definitions
- the invention relates to methods for producing weight-constant thrombin inhibitors, especially the spray drying of such inhibitors.
- the invention also relates to new salts of thrombin inhibitors, medicaments containing them and the use of these salts for the production of medicaments with an antithrombotic effect.
- the invention relates to new salts of the general formula I, their preparation and use, the formula I having the following meaning:
- n 0, 1, 2 and their tautomers.
- thrombin inhibitor I as acetate is described in WO 96/25426 (Example 93, page 128). If the active substance is isolated on an RP column operated with acetic acid buffer (see PCT application page 65, line 25/26), the product is obtained in the form of the acetic acid salt regardless of its history.
- the acetic acid salt is hygroscopic and forms a number of by-products during storage.
- Defined compounds of the formula I are obtained by titration of acidic solutions of the active ingredient with aqueous ammonia.
- the betaine of the active ingredient precipitates and can be obtained in pure form by filtering or centrifuging and drying.
- the hydrochlorides of the general formula I are obtained by adding stoichiometric amounts of HCl to the betaine.
- Suitable solvents are water, C ⁇ -C 6 alcohols, C ß ether, C ⁇ -C6 esters, toluene, xylenes, DMF, DMSO, THF in question.
- the product is isolated by filtration or centrifugation and drying.
- the active ingredient tends to irreversibly adsorb organic solvents.
- Organic solvent residues are disadvantageous for pharmaceutical preparations. Isolation from water would be an attractive process. This does not result in products that are constant in weight, since the active ingredient is highly hygroscopic. The extent of hygroscopy depends on the relative humidity.
- samples of the dry active substance are stored in desiccators in which a constant air humidity has been set by saturated salt solutions at a constant temperature.
- the change in weight is determined by weighing every few days.
- the weight gain is determined using the following formula:
- Weight gain x 100 dry matter
- the invention was therefore based on the object of producing an easy-to-use, constant-weight active ingredient. Surprisingly, it was found that, in contrast to all other drying techniques in vacuum, spray drying has constant, adjustable residual moisture and is therefore constant in weight during further processing. The amorphous form obtained is also of pharmacological interest because of the influence of crystallinity on the bioavailability.
- the aqueous solution of the active ingredient to be dried is atomized using a two-component nozzle.
- a gas flowing in cocurrent, preferably nitrogen, dries the distributed drops to amorphous solid particles.
- the solid particles are usually separated off in a cyclone.
- the exhaust gas is filtered and fed to a wash tower.
- the concentration of the solution to be dried is in the range from 5 to 40% by weight, preferably in the range from 15 to 25% by weight.
- the gas inlet temperature is in the range from 80 to 150 ° C, preferably in the range from 110 to 130 ° C.
- the gas outlet temperature is in the range from 30 to 70 ° C., preferably in the range from 50 to 60 ° C.
- the pressure of the atomizing gas is in the range from 1.1 to 10 bar, preferably in the range from 2 to 5 bar.
- the products manufactured in this way are compact and galenically easy to process.
- a product manufactured in this way can be open to the
- Air can be handled without quickly changing its weight.
- the spray-dried products of the general formula I show a weight gain of less than 1% after several days, even at a relative atmospheric humidity of 75%.
- the vacuum-dried and freeze-dried products of the general formula I have a weight gain of greater than 6% at 75% relative humidity.
- the compounds of the formula I are inhibitors of thrombin and can be used in the following indications:
- platelet derived growth factor P-selectin, ICAM-1, tissue factor
- inhibition e.g. NO synthesis in smooth muscle cells
- epithelial cells e.g. vascular endothelial cells
- thrombin-dependent, thromboembolic events such as deep vein thrombosis, pulmonary embolism, myocardial or cerebral infarction, atrial fibrillation, bypass occlusion,
- DIC disseminated intravascular coagulation
- Reocclusion and to shorten the reperfusion time when comedicated with thrombolytics such as streptokinase, urokinase, prourokinase, t-PA, APSAC, plasminogen activators from the salivary glands of animals and the recombinant and mutant forms of all these substances,
- the new compounds for the therapy and prophylaxis of thrombin-dependent thromboembolic events such as deep venous thrombosis, pulmonary embolism, myocardial or
- Cerebral infarction and unstable angina continue to be used for the therapy of disseminated intravascular coagulation (DIC). They are also suitable for combination therapy with thrombolytics such as streptokinase, urokinase, prourokinase, t-PA, APSAC and other plasminogen activators to shorten the reperfusion time and extend the reocclusion time.
- DIC disseminated intravascular coagulation
- Further preferred fields of application are the prevention of thrombin-dependent early reocclusion and late restenosis after percutaneous transluminal coronary angioplasia, the prevention of thrombin-induced proliferation of smooth muscle cells, the prevention of active thrombin accumulation in the CNS (e.g. in M. Alzheimer's disease), the fight against tumors and the prevention of mechanisms lead to adhesion and metastasis of tumor cells.
- the new compounds can also be used to coat artificial surfaces such as hemodialysis membranes and the hose systems and lines required for them, as well as oxygenators for extravascular circulation, stents and heart valves.
- the new compounds can also be used in diseases whose pathomechanism is based directly or indirectly on the proteolytic action of kininogenases, in particular kallikrein, for example in inflammatory diseases such as asthma. Pancreatitis, rhinitis, arthritis, urticaria and other internal inflammatory diseases.
- the compounds according to the invention can be administered in the usual way orally or parenterally (subcutaneously, intravenously, intramuscularly, intraperitoneally, rectally). It can also be applied with vapors or sprays through the nasopharynx. In particular, the compounds can be given orally.
- the dosage depends on the age, condition and weight of the patient and on the type of application.
- the daily dose of active ingredient per person is between approximately 10 and 2000 mg when administered orally and between approximately 1 and 200 mg when administered parenterally. This dose can be given in 2 to 4 single doses or once a day as a depot form.
- the new compounds can be used in the customary pharmaceutical application forms, solid or liquid, e.g. as tablets, film-coated tablets, capsules, powders, granules, dragees, suppositories, solutions, ointments, creams or sprays. These are manufactured in the usual way.
- the active ingredients can be processed with the usual pharmaceutical auxiliaries such as tablet binders, fillers, preservatives, tablet disintegrants, flow regulators, plasticizers, wetting agents, dispersants, emulsifiers, solvents, retardants, antioxidants and / or propellants (see H. Sucker et al.: Pharmaceuticals Technology, Thieme-Verlag, Stuttgart, 1978).
- the application forms thus obtained normally contain the active ingredient in an amount of 0.1 to 99% by weight.
