Description
BACKGROUND OF THE INVENTION
It is considered that when uric acid content in blood exceeds a certain limit, uric acid would deposit as sodium urate and deposition of sodium urate on the articular cavity or kidney would cause gout, renal disorders or vascular disorders. As known causes of hyperuricemia, there are reduced excretion of uric acid, excessive production of uric acid, abnormality of purine metabolizing enzyme, disease associated with hematopoietic organ or renal disorders, administration of chemicals such as pyrazinamide or thiazide, and the like. Irrespective of any cause, continuous hyperuricemia results in incidence of gout in most cases and if further worsened, leads to renal insufficiency or cardiovascular disorders. Further in the case of children, a disease called Lesch-Nyhan syndrome which is caused by excessive production of uric acid due to enzyme abnormality is known.
Since these diseases are caused by high blood concentration of uric acid, drugs having an activity of excreting uric acid, for example, probenecid, sulfinpyrazone or benzbromarone have been used for the treatment of hyperuricemia.
The present invention provides compounds having excellent properties as agents for the treatment of hyperuricemia.
DETAILED DESCRIPTION OF THE INVENTION
As a result of extensive investigations to solve the foregoing problems, the present inventors have found that a series of non-peptide type compounds having an angiotension II receptor-antagonizing activity are useful for the prevention or treatment of hyperuricemia. The present invention has thus been accomplished.
That is, the present invention relates to compositions for the prevention or treatment of hyperuricemia comprising a non-peptide type compound having an angiotensin II receptor-antagonizing activity.
The non-peptide type angiotensin II receptor antagonists which are used in the present invention may be any compounds as long as they are compounds which do not fall under the category of compounds formed by binding two or more amino acids through peptide bond (--COHN--) and have an antagonizing activity against angiotensin II receptor. As non-peptide type compounds having such an action of antagonizing an angiotensin II receptor, compounds described in, for example, the following publications, may be given:

The symbol " at each column means the same as the description at the column right above.
The non-peptide type antiotensin II receptor antagonist itself which is used in the present invention can be prepared and obtained by any one of the processes described in publications (a) through (o) and the patents (1) through (12) supra.
Next, the present invention is described more specifically, with reference to test examples.
TEST EXAMPLE
Uric acid excretion activity
Twenty-four (24) male adults (25 to 48 years old, 161 cm to 187 cm tall, weighing 48 kg to 85 kg) were divided into 4 groups, 6 per group. Compound No. 9 was orally administered under hunger in the form of capsules in Example 2, in a definite dose (25 mg, 50 mg, 100 mg or 200 mg) per person, by varying the dose in each group. Further in order to examine influence of diet on uric acid excretion increasing activity of Compound No. 9, the capsule of Example 2 containing 100 mg of Compound No. 9 was orally administered at 2 weeks after the test under hunger was completed. Concentration of uric acid in urine and blood was determined by the uricase-POD method at every definite period of time after the administration. The results are shown in Tables 11 through 14.
As is clear from Tables 11 through 14, the concentration of uric acid in serum decreased in 4 hours after medication dose-dependently. However, a tendency that the uric acid concentration was recovered to the concentration level prior to medication was noted 24 hours after. On the other hand, when medicated after meals, the concentration of uric acid in serum was kept as it decreased even 24 hours after.
The uric acid concentration in urine dose-dependently increased from 0 to 4 hours by administering Compound no. 9 in doses of 25 mg, 50 mg and 100 mg per person. In the dose of 200 mg, however, the uric acid concentration in urine did not increase dose-dependently but was kept almost constant. On the other hand, when medicated after meals, the uric acid concentration in urine increased in 0 to 8 hours.
The foregoing results reveal that the non-peptide type compounds having an angiotensin II receptor-antagonizing activity in accordance with the present invention have the activities of reducing the uric acid concentration in blood and increasing excretion of uric acid into urine. Accordingly, the non-peptide type compounds having an angiotensin II receptor-antagonizing activity in accordance with the present invention are useful as drugs for the prevention or treatment of hyperuricemia.
Where the non-peptide type compounds having an angiotensin II receptor-antagonizing activity in accordance with the present invention are used as compositions for the prevention or treatment of hyperuricemia, the non-peptide type compounds having an angiotensin II receptor-antagonizing activity may be used singly or in the form of pharmaceutical compositions comprising the antagonists and pharmaceutically acceptable carriers.
For preparing the pharmaceutical compositions from the compounds of the present invention, inert and pharmaceutically acceptable carriers may be solid or liquid. The composition in the solid form include powders, tablets, dispersible granules, capsules, cachets and suppositories. The solid carrier may be one or more substances which can also act as a diluent, a flavor, a solubilizing agent, a lubricant, a suspending agent, a binder or a tablet disintegrator. The solid carrier may also be an encapsulated substance. In powder, the carrier is a finely divided solid which is mixed with the active compound. In a tablet, the active compound is mixed with a carrier having a required binding property in an appropriate proportion and the resulting mixture is compressed into a desired shape and size. The powder and tablet contain preferably 5 or 10 to about 70% of the active compound. Suitable examples of the solid carrier include magnesium carbonate, magnesium stearate, talc, sugar, lactose, pectin, dextrin, starch, gelatin, colloidal silicon dioxide, tragacanth gum, sodium carboxymethylstarch, methylcellulose, fine crystalline cellulose, sodium carboxymethylcellulose, low melting point wax, cacao butter, etc. The term preparing into pharmaceutical preparations is contemplated to mean a formulation of an encapsulating substance as a carrier in which the active compound (using or without using any other carrier) is surrounded by the carrier and as the result, the carrier gives a capsule together with the active compound, and the inactive compound. Likewise, a cachet also falls under the term. The tablet, powder, cachet and capsule may be used as a solid form of application suited for oral administration.
In preparing a suppository, a low melting point wax such as a mixture of fatty acid glycerides or cacaco butter is first allowed to melt and the active compound is uniformly dispersed in the melt by, e.g., stirring. The melted homogeneous mixture is then poured into a mold of suitable size, cooled and solidified.
The preparation of liquid form includes a solution, a suspension and an emulsion. Examples of the liquid carrier are water for parenteral injection or an aqueous propylene glycol solution. The liquid preparation may also be a solution in a polyethylene glycol aqueous solution. The aqueous solution suited for oral application may be prepared by dissolving the active compound in water and, if necessary, adding a suitable coloring agent, a flavor, a stabilizer and a thickener. The aqueous suspension suitable for oral application may be prepared by dispersing the active compound finely divided in water together with a viscous substance, e.g., natural or synthetic rubber, resin, methylcellulose, sodium carboxymethylcellulose and other known suspending agents.
The composition also includes a preparation in a solid form contemplated to be converted into a preparation in a liquid form for oral or parenteral administration just before application. Such a liquid form includes a solution, a suspension and an emulsion. More advantageously, these preparations in a particular solid form may be provided in a single dosage form and used to make a single liquid dosage as it stands. Instead, a sufficient dose of solid may also be provided so as to ensure each liquid dosage in applications several times, by changing to liquid form and then measuring a definite volume of the preparation in a liquid form with a syringe, a teaspoon or other container for determining its volume, etc. In case that liquid dosages to be applied several times are thus provided, it is preferred to maintain the unused portion of the liquid dosage at a low temperature (for example, under cooling). The preparation in a solid form designed to be converted into a liquid form may contain, in addition to the active compound, a flavor, a coloring agent, a stabilizer, a buffer, an artificial and natural sweetner, a dispersing agent, a thickener, a solubilizing agent, etc. The liquid used to prepare the preparation in a liquid form is water, isotonic water, ethanol, glycerine, propylene glycol, etc. and a mixture thereof. The liquid used is generally chosen in association with mode of application. For example, a liquid preparation containing large quantities of ethanol is inappropriate for parenteral application.
It is preferred that the pharmaceutical preparation may be in a single dosage form. In such a form, the preparation may be divided into a single dose containing a suitable dose of the active compound. The mode of application in a single dose may be a packaged form containing a discontinuous amount of the preparation, for example, a packaged tablet, capsule and powders in a vial or an ampule. The mode of application in a single dose may be a capsule, cachet or a tablet per se or may be a suitable number of any of its packaged forms.
An amount of the active compound in the single dosage of the preparation may be varied or controlled in a range of 0.1 to 500 mg, preferably 1 to 100 mg, depending upon specific application and titer of the active compound. If necessary, the composition may also contain other compatible therapeutic agents.
In the aforesaid therapeutic use, a daily dose range used for a patient weighing 70 kg is 0.1 to 150 mg per 1 kg of body weight, preferably 1 to 100 mg per 1 kg of body weight, in the case of oral administration; in the case of parenteral administration, 0.1 to 50 mg, preferably 0.1 to 20 mg, per 1 kg of body weight. However, the dose may be varied depending upon necessity for patient, condition of disease to be treated and compound to be used.
Determination of an adequate dose for a specific circumstance may be within the skill of a prescriber. In general, treatment is initiated with a dose less than the optimum dose of a compound. Then, the dose is gradually increased until the best effect is achieved under the situation. If necessary for the sake of convenience, a daily dose may be divided and portionwise administered.
The present invention is further described by referring to the following examples but is not deemed to be limited to these examples:
