The present invention is based on the chemical formula 9-chloro-5-oxo-7-(1H
-tetrazol-5-yl)-5H-[1]benzopyrano[2,3-b]pyridine, its salts (sodium salt, potassium salt, ammonium salt, etc.) and/or its hydrate as an active ingredient.High uric acid Concerning drugs for bloodemia treatment. The present applicant first disclosed in Japanese Patent Application Laid-open No. 151897/1989 (Japanese Patent Publication No. 16432/1989) that the compound of formula () and its salts are useful as antiallergic agents, and currently, for example, “New drugs and clinical practice”
As stated in Volume 29, page 1991 (1980),
The sodium salt pentahydrate of the compound of formula () is being used in clinical trials as an antiallergic agent and a therapeutic agent for bronchial asthma. As a result of intensive research into new uses of the compound of formula (), the present inventors arrived at the new finding that the compound of the present invention has an excellent uric acid excretion effect in animals and humans, and completed the present invention. That is, the present invention can be used to prevent or treat non-gouty hyperuricemia in which serum uric acid levels have increased, symptoms of more advanced gout, prevention of myocardial infarction, and treatment of hypertension complicated by hyperuricemia. The present invention provides a hyperuricemia drug for treatment. Next, the present invention will be specifically explained based on test examples. Test compound Compound A: 9-chloro-5-oxo-7-(1H
-tetrazol-5-yl)-5H-[1]Benzopyrano[2,3-b]pyridine sodium salt.
Pentahydrate test example 1 Uric acid excretion effect in rats Compound (A) was orally administered to male rats (body weight 160-205 g, 8 animals per group), and then placed in a urine collection cage for 6 days.
Urine excreted within the time period was collected, and urinary uric acid was measured by a colorimetric method. The results are shown in Table 1.

The numbers in brackets in the table indicate the percentage decrease from before administration. Test Example 3 Urinary uric acid excretion effect in humans 120 mg of Compound (A) was orally administered once to eight healthy male adults. The urinary uric acid excreted within 0 to 3 hours and 3 to 8 hours after administration was measured by a colorimetric method, and compared with the urinary uric acid measured within the same time on the previous day (hereinafter referred to as the previous value), Table 1 shows the results converted into hourly amounts.

[Table] Mean value ± standard error ※※ P<0.01 (relative to previous value)
As is clear from the above test examples, compound (A) lowers serum uric acid levels in animals and humans, and has a uric acid excretion effect. Moreover, almost no side effects are observed even after long-term use. Compound (A) also has very low toxicity; for example, the LD 50 value for both mice and rats is 16,000 mg/d after oral administration.
Kg or more. Thus, compound (A) can be safely administered in the form of a pharmaceutical formulation with suitable and conventional carriers for the treatment and prevention of hyperuricemia without causing side effects. Pharmaceutical formulations may take the usual forms such as capsules, tablets, powders, granules, etc. for oral administration. for example
60mg tablets, 10% fine granules are prepared from the following composition: 60mg Tablet Compound (A) (as anhydrous) 60.0mg Cellulose Calcium Glycolate 130.2 Hydroxypropylcellulose 3.5 Magnesium Aluminate Metasilicate 28.5 Talc 3.0 Magnesium Stearate 2.25 10% Granule Compound (A) (as anhydrous) 500g Sodium bicarbonate 250 D-mannite 4060 Hydroxypropyl cellulose 45 Talc 5 The dosage of compound (A) varies slightly depending on the target disease, symptoms, etc., but in the case of oral administration, it is usually about 120 to 720 mg per day for adults.
