## Title
Blood lipid ameliorant composition

## Abstract

A blood lipid ameliorating composition containing simvastatin and one or more ingredients selected from a riboflavin compound, a d-α-tocopherol compound, an ascorbic acid compound, pantethine, and taurine.

## Background
This is a continuation-in-part of PCT/JP01/10914 filed Dec. 12, 2001.


BACKGROUND OF THE INVENTION
The present invention relates to a blood lipid ameliorating composition that contains simvastatin in combination with one or more ingredients selected from the group consisting of a riboflavin derivative, a tocopherol derivative, an ascorbic acid derivative, pantethine, and taurine.
Since an increase in blood lipid peroxide levels causes damage to endothelial cells, enhances platelet aggregation, and promotes foam cell forming, all of which contribute to arteriosclerosis, lipid peroxide-lowering agents are useful agents.
Simvastatin reduces total cholesterol levels in the blood by inhibiting HMG-CoA reductase activity. Furthermore, it is known that simvastatin reduces lipid peroxide levels in the blood.
The anti-oxidative actions of riboflavin derivatives, tocopherol derivatives, and ascorbic acid derivatives are well known. Furthermore, it is known that pantethine and taurine reduce lipid peroxide levels in the blood (References: Sulfur Amino Acids, Vol. 7, No.1, 1984, p. 201-205; Geriatr. Med., Vol. 19, No. 3, p. 415-422).
BRIEF DESCRIPTION OF THE INVENTION
The present inventors investigated drug compositions that decrease lipid peroxide levels in the blood, and found that co-administration of simvastatin with a certain vitamin or taurine reduces lipid peroxide levels in the blood, and completed the present invention.
The present invention comprises a blood lipid ameliorating composition which contains simvastatin in combination with one or more ingredients selected from the group consisting of a riboflavin derivative, a tocopherol derivative, an ascorbic acid derivative, pantethine, and taurine. The present invention also comprises the use of this composition to ameliorate blood lipid levels.

The amount of each component described above is weighed and prepared according to the methods described in the “General Rules for Preparations of Liquids and Solutions” in “The Pharmacopeia of Japan”.
Assay of Blood Lipid Ameliorating Effects
Test Methods
(1) Test Compounds
Simvastatin was synthesized at Chemtech Labo., Inc. and riboflavin butyrate, d-α-tocopherol acetate, ascorbic acid, pantethine, and taurine were purchased from Mitsubishi-Tokyo Pharmaceutical Inc., Eisai Co., Ltd., NIPPON ROCHE K.K., Nacalai Tesque, Inc., and Dai-ich Pharmaceutical Co., Ltd., respectively.
(2) Test Animals
Beagle dogs aged 5 months were purchased from Covance Research Products Inc. and used after 1 month of quarantine and acclimatisaton breeding.
(3) Preparation Forms for Administration, Methods for Preparation of the Formulation, and Method for Stocking the Formulation
The required amounts of simvastatin or each component of the combination drug calculated from the body weight of each dog were weighed and filled in a gelatin capsule (1⁄2 ounce) purchased from TORPAC Inc. Capsules filled with simvastatin were stocked in a refrigerator and those filled with combination drugs stocked at room temperature until use.
The combination drugs were filled in identical gelatin capsules.
(4) Route of Administration and Administration Period
Simvastatin or combination drug capsules were forcibly orally administered to each of the test animals once daily between 9:00 and 12:30. Animals were fasted for 2 or 3 hr prior to administration of the capsules.
The administration period was 11 successive days.
(5) Preparation of Test Samples and Procedures
Blood (10 mL) was collected from the superficial radial vein 2 or 1 weeks prior to administration and 4, 8, and 12 days after administration was started. Animals were fasted for approximately 18 hr prior to blood collection. Collected blood was placed in a test tube and left at room temperature for 0.5-1 hr, before being centrifuged (3,000 rpm for 10 min). The obtained serum was used for assays of blood levels of lipid peroxides, total cholesterol, triglycerides, free fatty acids, GOT, and CPK according to Yagi's methods, CEH-COD-POD methods, GK-GPO-POD methods, ACS-ACOD methods, UV-rate methods, and UV-rate methods, respectively. (For ACS-ACOD (Acyl-CoA synthetase-Acyl-CoA oxidase peroxidase) methods, CEH-COD-POD (Cholesterol ester hydrolase-Cholesteroloxidase-Peroxidase) methods, Yagis methods and GK-GPO-POD (Glycerokinase-Glycerolphosphateoxidase-Peroxidase)methods, see: Kanai's Manual of Clinical Laboratory Medicine; 31st Edition (September 1998), Kanehara & Co., Ltd.)
All these levels were determined using a fluorometer (Hitachi, Ltd., F3000), a full automatic analyzer (Monarch, Instrumentation Laboratory), and an automatic analyzer (7170, Hitachi, Ltd.).
RESULTS
Lipid peroxide levels, etc. in the blood collected from dogs treated with either simvastatin, ascorbic acid, riboflavin butyrate, d-α-tocopherol acetate, pantethine or taurine were determined. The levels of lipid peroxides and other substances described above in the blood collected from dogs co-administered with simvastatin and a composition which contains one or more substances selected from riboflavin butyrate, d-α-tocopherol acetate, ascorbic acid, pantethine and taurine were also similarly determined. All these values in dogs treated with one of the drugs described above were converted to their relative ratios against their averaged pre-dosing levels (100) determined 2 and 1 weeks prior to drug administration. The averaged value in each group was obtained from 5 animals per group.
