[29a] [29b] Definitions of the specific embodiments of the invention as claimed herein follow. [29c] [29d] According to a first ment of the invention, there is provided a pharmaceutical composition for preventing or treating ipidemia comprising a compound of Formula 1 or its pharmaceutically acceptable salt; and olmesartan medoxomil or its salt as active ingredients: <Formula 1> [29e] [29f] According to a second embodiment of the invention, there is provided use of active ingredients comprising a compound of a 1 or its pharmaceutically acceptable salt; and olmesartan medoxomil or its salt for the manufacture of a medicament for preventing or treating hyperlipidemia: <Formula 1> The present invention will be described in further detail with reference to the following examples. These examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

Example 1. Evaluation of triglyceride-inhibitory activities in hypercholesterolemia-induced animals (1) Test Method Male New d White rabbits were used as a test animal. All s, except for the G1 group animals (negative control group, n=4), were fed with an irradiation- [TEXT CONTINUES ON PAGE 7] sterilized hypercholesterolemia diet, i.e., DYET# 620007 (Purina # 5321 chow with 1% cholesterol, Dyets, Inc., Bethlehem, PA 18017), which was purchased from Central Lab. Animal Inc. In order to induce hypercholesterolemia, the animals were supplied with the diet for more than 8 weeks. After collecting the blood samples from the animals, serum mical analyses were performed thereon. Animals having total terol levels of approximately 870 mg/dL were selected as a hypercholes— terolemia—induced animal. The test materials were dissolved in saline containing 0.5% carboxymethylcellulose sodium and 1% Tween 80 and then administered ly into the stomach using an oral syringe adapted with a latex catheter, once per day for 4 weeks. The test groups are as in the following Table 1.

(2) Results The triglyceride concentrations in the hypercholesterolemia—induced animals as in the above are presented in the following Table 2. The values in Table 2 represent average triglyceride concentrations (mg/dL) of the respective group.

Table 2 [Table 2] As shown in Table 2, when the compound of Formula 1 and/or the angiotensin II receptor blockers were orally administered repeatedly for 4 weeks, the co— stration groups (G4 to G7) showed remarkably high ceride—inhibitory ac— tivities, in comparison with the group administered with the compound of Formula 1 alone (G3, 356.7 mg/dL at the 4 weeks after ting the administration). ally, the co—administration group of the compound of Formula 1 and telmisartan (G5) showed the most potent triglyceride—inhibitory activity. Therefore, it is expected that the combination of the compound of Formula 1 and the ensin II receptor blocker such as olmesartan, olmesartan medoxomil, telmisartan, losartan, or valsartan can be ly applied for preventing or treating hypertriglyceridemia or hypertriglyc— eridemia—associated diseases.

Example 2. Evaluation of activities in hypertriglyceridemia and hypercholes- terolemia-induced animals (1) Test Method Male New d White rabbits were used as a test animal. All animals, except for the G1 group animals (negative control group), were fed with an irradiation—sterilized hypertriglyceridemia and hypercholesterolemia diet, i.e., DYET# 621082 (Purina# 5321 chow with 0.5% cholesterol, 14% coconut oil & 2% Maltose Dextrin, Dyets, Inc., Bethlehem, PA 18017), which was purchased from Saeronbio Inc. In order to induce hypertriglyceridemia and hypercholesterolemia, the s were supplied with the diet for more than 4 weeks. After collecting the blood samples from the animals, serum biochemical analyses were performed thereon. Animals showing significant changes in total cholesterol levels and triglyceride levels were selected, in comparison with the non—treated control group. The selected s were divided into 4 groups on the basis of the total cholesterol levels and ceride , thereby all the groups having substantially equal average values in the total cholesterol levels and triglyceride levels. The test materials were dissolved in saline containing 0.5% carboxymethyl— cellulose sodium and 1% Tween 80 and then administered directly into the stomach using an oral syringe adapted with a latex catheter, once per day for 4 weeks. The test groups are as in the following Table 3.

(2) Results The triglyceride concentrations in the hypertriglyceridemia and hypercholes— terolemia—induced animals as in the above are presented in the following Table 4. The values in Table 4 represent average triglyceride trations (mg/dL) of the re— spective group.

Table 4 [Table 4] Percent inhibition of triglyceride1n the blood (%) As shown in Table 4, when the compound of Formula 1 and/or olmesartan medoxomil were orally administered repeatedly for 4 weeks, the groups administered with the compound of Formula 1 alone (G3) or olmesartan medoxomil alone (G4) re— spectively showed 10.2% and 33.4% inhibitions in the triglyceride levels, in comparison with the G2 group. However, the inistration groups (G5) showed 57.3% inhibition in the triglyceride level in comparison with the G2 group. The triglyceride—inhibitory activity (i.e., 57.3% inhibition) of G5 was more potent in ison with the sum of triglyceride—inhibitory activities of G3 and G4 (i.e., 43.6% inhibition). Therefore, it can be acknowledged that the combination of the compound of Formula 1 and the angiotensin II receptor blocker such as olmesartan medoxomil provides potent synergistic effect in inhibiting triglyceride levels.

The HDL cholesterol concentrations in the blood samples are presented in the following Table 5. The values in Table 5 represent average HDL terol — trations (mg/dL) measured from the blood sample of the respective group.

Table 5 [Table 5] Percentincrease of HDL cholesterol level (%) As shown in Table 5, when the compound of Formula 1 and/or rtan medoxomil were orally stered repeatedly for 4 weeks, the groups administered with the compound of Formula 1 alone (G3) or rtan medoxomil alone (G4) re— spectively showed 37.9% and 2.6% ses in the blood HDL terol levels, in comparison with the G2 group. However, the co—administration groups (G5) showed 58.7% increase in the blood HDL cholesterol level in comparison with the G2 group; and showed potent synergistic effect in comparison with the respective G3 and G4 groups. Therefore, it is expected that the combination of the compound of a 1 and the angiotensin II receptor blocker such as olmesartan medoxomil can be usefully applied for preventing or treating hypercholesterolemia and combined hyperlipidemia, as well as hypertriglyceridemia (including hypertriglyceridemia—associated diseases).
