Definitions
- the present invention relates to a therapeutic or prophylactic agent for hyperlipidemia.
- Lipid components such as cholesterol, neutral fats, phospholipids and free fatty acids in blood are in the form of water-soluble lipoproteins in blood, and lipoproteins are ultra-low-density lipoproteins due to their specific gravity.
- VLDL low-density lipoprotein
- HDL high-density lipoprotein
- arteriosclerotic diseases such as myocardial infarction, angina, and cerebral infarction develop and progress. Therefore, it is important to lower the blood levels of these lipid components to normal levels for the treatment of hyperlipidemia, and to maintain the normal levels to prevent hyperlipidemia. is important.
- Taurine (aminoethyl sulfonic acid) is a sulfur-containing amino acid with a very simple chemical structure with a molecular weight of 125.14, and its pharmacological action is known to be widespread in the cerebral nervous system, circulatory system, hepatobiliary system, and others. Have been. The effects of taurine on cholesterol metabolism are known to lower serum cholesterol via a bile effect and to suppress cholesterol gallstone formation.
- 7-Oryzanol is known to have an effect of inhibiting cholesterol absorption and improving lipoprotein metabolism.
- diet is the first treatment for hyperlipidemia, but when sufficient effects cannot be obtained, drug treatment is required.
- An object of the present invention is to provide a therapeutic and prophylactic agent for hyperlipidemia that is safe even if taken for a long period of time. It is to be. Disclosure of the invention
- the present inventors have found that, in order to improve the metabolism of lipid components such as excessive cholesterol in the body, a metabolic improving effect is obtained by simultaneously administering phosphorus and 7-oryzanol, rather than administering taurine or aorizanol alone.
- the inventors have found that they are further enhanced, and based on the findings, completed the present invention.
- the present invention is a therapeutic or prophylactic agent for hyperlipidemia, which comprises taurine and a-oryzanol as active ingredients.
- the therapeutic or prophylactic agent for hyperlipidemia of the present invention reduces the blood concentration of lipid components such as excess cholesterol, neutral fat, phospholipids and free fatty acids in the body, and further improves lipoprotein metabolism. Therefore, the therapeutic drug for hyperlipidemia, ⁇ , is useful as a preventive drug. In particular, it has no side effects and can be taken safely for a long period of time, so it is extremely useful as a preventive for hyperlipidemia.
- the effective dose of taurine is 100 mg to 6000 nig per FU for a healthy adult, and preferably 1000 mg to 3000 mg.
- the effective dose of ⁇ -oryzanol is 1 mg to 6000 nig / day for healthy adults, preferably 5 mg to 500 nig.
- the therapeutic or prophylactic agent for hyperlipidemia of the present invention may contain other known additives as necessary, for example, excipients, disintegrants, binders, lubricants, antioxidants, coating agents, Coloring agents, flavoring agents, surfactants, plasticizers, and the like can be mixed to produce granules, powders, capsules, tablets, dry syrups, liquids, and other preparations in the usual manner.
- the preparation containing taurine and a-oryzanol according to the present invention as active ingredients can be made into a more effective preparation for treating and preventing hyperlipidemia by blending pantethine dinicotinic acid.
- the preparation according to the present invention containing taurine and a-oryzanol as active ingredients has an effect of lowering blood levels of cholesterol and triglyceride, and further has an effect of improving lipoprotein metabolism, and is a therapeutic drug for hyperlipidemia. Or it is useful as a prophylactic. In particular, it has no side effects and can be taken safely for a long period of time, so it is extremely useful as a preventive for hyperlipidemia.

- Each group was fed and maintained for 45 days. After feeding, blood was collected from the tail vein and serum cholesterol levels were measured. After breeding, the liver was removed and cholesterol levels were measured.
- the mesenteric artery was excised, the surrounding fat was removed, stained with Sudan II, and the number of fat deposits was measured under S shellfish microscopy to determine the rate of inhibition of fat deposition in the mesenteric artery.
- Example 1 The administration group maintained a low serum cholesterol level as compared to each group. From the liver cholesterol concentration value, the cholesterol suppression rate of the liver was determined by the following formula. Cholesterol 1 (Control group score 1) 1 — (Each group score 1)
- Table 2 shows the liver cholesterol concentration and the liver cholesterol inhibition rate. As compared with each group, the administration group of Example 1 kept the cholesterol concentration in the liver low and showed a high rate of suppressing fat deposition.
- the fat deposition judgment is divided into four stages: score 1 from 0 to 20, score 2 from 20 to 100, score 3 from 100 to 200, and score 4 from 200 or more.
- score 1 from 0 to 20
- score 2 from 20 to 100
- score 3 from 100 to 200
- score 4 from 200 or more.
- the score was determined, the average of the scores of each group was calculated, and the rate of inhibition of mesenteric artery fat deposition in each group was calculated by the following formula.
- Table 3 shows the average of the fat deposition judgment scores of each group and the fat deposition inhibition rate in the mesenteric artery.
- Example 1 The administration group showed a higher fat deposition inhibition rate as compared with each group. table 1
