Definitions
- the invention relates to pharmaceutical preparations containing at least one active pharmaceutical ingredient and 2-pyrrolidone as solubilizer.
- Active pharmaceutical ingredients which are sparingly soluble in water are preferably used, in particular 4- [4- (3-chloro-4-methoxy-benzylamino) benzo [4,5] thieno [2,3-d] pyrimidin-2-yl] - cyclohexane carboxylic acid or one of the pharmaceutically acceptable salts, 4- [4- (3-chloro-4-hydroxy-
- the active pharmaceutical ingredient is added intravenously to the organism in the form of a solution for injection, its absolute bioavailability lies, i.e. the proportion of the drug that remains unchanged in the systemic blood, i.e. gets into the big cycle, at 100%.
- a poorly soluble active pharmaceutical ingredient When administered orally, it must first dissolve so that it can overcome the entry barriers, for example the gastrointestinal tract, the oral mucosa, nasal membranes or the skin, in particular the stratum corneum, or can be resorbed by the body. Theoretically the best
- Dosage form for oral administration is a solution, because in this formulation the active ingredient does not require a dissolution step before it can be absorbed.
- the dissolution rate can also be increased by adding a solubilizer, for example alcohols, glycerol, propylene glycol, polyethylene glycol or sorbitol.
- a solubilizer for example alcohols, glycerol, propylene glycol, polyethylene glycol or sorbitol.
- microemulsions in which the active ingredient is present in solution.
- Known formulations using this technique apply, as well as methods for the preparation of microemulsions are described in US 5,141,961, US 5,376,688, US 5,430,017, US 5,688,761, US 5,505,961, US 5,707,648, US 5,759,566 or US 5,912,011.
- the object of the invention was to develop new pharmaceuticals in the form of pharmaceutical preparations for the oral administration of active pharmaceutical ingredients, in particular 4- [4- (3-chloro-4-methoxy-benzylamino) -benzo [4,5] thieno [2,3 -d] pyrimidin-2-yl] - cyclohexane carboxylic acid or its pharmaceutically acceptable salts, 4- [4- (3-chloro-4-hydroxy-benzylamino) -benzo [4,5] thieno [2,3-d] pyrimidin- 2-yl] -cyclohexane carboxylic acid or its pharmaceutically acceptable salts or 5- [1 - (3, 4-dimethoxy-benzoyl) -1, 2,3,4-tetrahydro-quinolin-6-yl] -6-methyl-3, To provide 6-dihydro- [1, 3,4] thiadiazin-2-one, which have a very good bioavailability and at the same time allow the active ingredient to flood into the body quickly
- It can be used in particular to combat heart muscle diseases or heart failure.
- PDE V inhibitors cGMP phosphodiesterase
- Compounds are suitable for the treatment of diseases of the cardiovascular system, in particular heart failure and for the treatment and / or therapy of erectile dysfunction.
- the solubility of the ethanolamine salt is 22 ng / ml in phosphate buffer (pH 1.0), 19 ng / ml in phosphate buffer (pH 7.0) and in the gastrointestinal tract, i.e. under physiological conditions, 10 ng / ml.
- the solubility of the ethanolamine salt in artificial gastric juice is 1 mg / 100 ml, in artificial intestinal juice 6 mg / 100 ml in phosphate buffer (pH 1.0) 22 ng / ml, in phosphate buffer (pH 6) 1.6 ng / ml and in phosphate buffer (pH 10) 11.4 ⁇ g / ml.
- the solution of the active pharmaceutical ingredient determines the rate of bioavailability.
- the first metabolite of 4- [4- (3-chloro-4-methoxy-benzylamino) - benzo [4,5] thieno [2,3-d] pyrimidin-2-yl] cyclohexane carboxylic acid or the pharmaceutically acceptable salts of 4 - [4- (3-Chloro-4-methoxybenzylamino) benzo [4,5] thieno [2,3-d] pyrimidin-2-yl] - cyclohexane carboxylic acid is 4- [4- (3-chloro-4 -hydroxy-benzylamino) -benzo [4,5] thieno [2,3-d] pyhmidin-2-yl] cyclohexane carboxylic acid. 4- [4- (3- (3-
- Chloro-4-hydroxy-benzylamino) benzo [4,5] thieno [2,3-d] pyrimidin-2-yl] cyclohexane carboxylic acid or its pharmaceutically acceptable salts are also effective inhibitors of cGMP phosphodiesterase (PDE V inhibitors)
- PDE V inhibitors cGMP phosphodiesterase
- Other poorly soluble active pharmaceutical ingredients that are suitable for a preparation according to the invention are active pharmaceutical ingredients whose solubility in water is less than 100 ⁇ g / ml.
- Examples of poorly soluble active pharmaceutical ingredients which are suitable for a preparation according to the invention are triamteren, phenytoin, mebendazole,
- Glibenclamide naproxen, nabumetone, medroxyprogesterone acetate, estradiol, lovastatin, clotrimazole, danazol, cinnarizine, loratadine, sitosterol or probucol.
- the object was achieved by finding the preparations according to the invention.
- the invention relates to a pharmaceutical preparation containing at least one active pharmaceutical ingredient, in particular a poorly soluble active pharmaceutical ingredient, and 2-pyrrolidone as
- the pharmaceutical preparation is preferably administered orally.
- the invention relates to a pharmaceutical preparation containing at least one active pharmaceutical ingredient, in particular a poorly soluble active pharmaceutical ingredient, a lipid-like auxiliary and 2-pyrrolidone as a solubilizer.
- the invention also relates to a pharmaceutical preparation containing at least one active pharmaceutical ingredient, in particular a poorly soluble active pharmaceutical ingredient, a carrier and 2-pyrrolidone as a solubilizer.
