CROSS REFERENCE TO RELATED APPLICATIONS 
     This application is a National Stage of International Application No. PCT/KR2014/002178 filed Mar. 14, 2014, claiming priority based on Korean Patent Application No. 10-2013-0027114, filed Mar. 14, 2013, the contents of all of which are incorporated herein by reference in their entirety. 
     TECHNICAL FIELD 
     The present disclosure relates to a pharmaceutical combination preparation that dissolution is improved including fimasartan and rosuvastatin. 
     BACKGROUND ART 
     Apropos of hypertension, it is important to control blood pressure steadily below certain pressure because preventing coronary artery diseases such as stroke, cardiac failure and myocardial infarction, and cardiovascular complication such as renal insufficiency which threat life by keeping blood pressure in the normal range is more important than treating blood pressure directly. Selection of a therapeutic agent should be made carefully because therapeutic agent for blood pressure is required to be administered in long-term. Therefore, side effects incurred from long-term use of drug are needed to be reduced by combining drugs having different mechanisms rather than selecting only one drug and by reducing drug dosage via the combined administration for keeping blood pressure in the normal range over long periods. 
     However, there are problems such as decrease of medicinal effect and incurrence of side effects due to drug combination because absorption, metabolism, distribution, expression of drug effect, and excretion-related transporter, metabolic enzyme and gene of each drug have different property and show different actions when taking two or more ingredients. For instance, drug can cause problems in absorption, metabolism and excretion in everywhere at every phase such as the first phase of passing the intestinal wall, the second phase of influx into the liver, the third phase of activation via metabolized in the hepatocyte and the fourth phase of leakage from the hepatocyte through the biliary tract among others. Especially, disintegration and dissolution patterns of active ingredients according to pH cause a lot of problems in drug effectiveness when performing complex treatment. 
     Angiotensin II receptor blocker (ARB) is a drug effective in depressing blood pressure in both myocardial systole and diastole by blocking conjugation of angiotensin II which is one of the original substances that causes vasoconstriction with AT1 receptor among angiotensin receptors, and there are about 10 series of compound group including pharmaceutically acceptable salt. Also, these are being used for hypertension-related symptoms solely upon patients having mild through moderate symptoms or with angiotensin converting enzyme inhibitor which exhibits anti-hypertensive effect in similar mechanism [Angiotensin II Receptor Antagonist: An Overview, Am. J. Health-Syst. Pharm. 57(13): 1231-1238, 2000]. 
     Fimasartan, one of the angiotensin II receptor blockers (ARB), is 2-n-butyl-5-dimethylaminothiocarbonylmethyl-6-methyl-3-[[2-(1H-tetrazol-5-yl)biphenyl-4-yl]methyl]pyrimidin-4(3H)-one and has a chemical formula 1, and it is approved under the title of KANARB® and currently available in the market (Korean Patent Registration No. 10-1058284). 
     
       
                 
         
             
             
         
      
     
     HMG-CoA reductase inhibitor has effects of decreasing blood lipid concentration and cholesterol by preventing the reduction of HMG-CoA to be mevalonate, and thus it is used for hyperlipidemia, hypercholesterolemia and atherosclerosis. 
     Rosuvastatin, one of the HMG-CoA (3-hydroxy-3-methylglutaryl-CoA) reductase inhibitor, is (E)-7-[4-(4-fluorophenyl)-6-isopropyl-2-[methyl(methylsulfonyl)amino]pyrimidin-5-yl]-(3R,5S)-3,5-dihydroxyhept-6-enoic acid and has a structure of chemical formula 2, and it controls synthetic pathway of cholesterol and it is approved under the title of CRESTOR® and currently available in the market (Korean Patent Registration No. 10-0105432). 
     
       
                 
         
             
             
         
      
     
     Fimasartan and rosuvastatin combination preparation having different acting mechanisms can be used for hypertension treatment but these combination preparation have a problem of affecting disintegration and dissolution of each active ingredient due to effect of interference to each other. That is, fimasartan exhibits decent solubility pattern under comparatively high pH media such as purified water and pH 6.8 dissolution media, but its solubility decreases under low pH media (i.e. pH 1.0-pH 4.0) and KANARB® which is a currently available fimasartan formulation in the market exhibits similar solubility pattern. 
     According to the properties of fimasartan explained above, problem of decreasing disintegration and dissolution due to interference between fimasartan and rosuvastatin is raised when preparing combination preparation with rosuvastatin. Especially, decrease of dissolution under low pH media could seriously affect bioavailability at the stomach where initial disintegration and dissolution occurs at the time of oral administration. 
     Under these circumstances, a research on a method of keeping constant disintegration and dissolution rates of fimasartan and rosuvastatin in spite of pH variation in the normal stomach is required.

     1. Example 1 
     (1) Preparation of the Granular Part of the Fimasartan 
     The granular part of the fimasartan of Example 1 was prepared to have the same weight per unit dosage form to Table 1. Fimasartan potassium trihydrate was put into the part of the microcrystalline cellulose and mixed for about two minutes, and sieved through a No. 30 mesh screen twice. Put the sieved mixture, the rest of the microcrystalline cellulose and part of the croscarmellose sodium in a high speed mixer and mixed for about three minutes. Binder solution was separately prepared by dissolving hydroxypropyl cellulose in 65 mL of purified water. 
     The prepared binder solution was put into the high speed mixer, sieved through No. 20 mesh screen after wet granulation with a mixed solution, and dried. Fimasartan granules were prepared through putting the rest of the croscarmellose sodium in the dried granular part of the fimasartan and mixing in a double cone mixer for five minutes and supplementally mixing with the magnesium stearate for five minutes. 
     (2) Preparation of the Mixed Part of the Rosuvastatin 
     The mixed part of the rosuvastatin of Example 1 was prepared to have the same weight per unit dosage form to Table 1. Rosuvastatin calcium was put into the meglumine and part of the lactose and mixed for about two minutes, and sieved through a No. 30 mesh screen twice. Put the sieved mixture, the rest of the lactose, microcrystalline cellulose and crospovidone in a double cone mixer and mixed for about three minutes. Magnesium stearate was added as a lubricant and supplementally mixed for about five minutes. 
     (3) Tablet Compression 
     The combination preparation was prepared by tableting with 20 kN of tableting pressure by using a rotary tablet compression machine (PICCOLA DC, RIVA) to have 249˜251 mg of weight (250.0 mg of theoretical weight) and 9˜10 kp of hardness per one tablet. Friability of the tablets obtained through the above process was measured by using a friability tester (25 rpm, 100 free falls). The measured friability was 0.1% and below, and thus hardness of the tablets was fine. 
     2. Example 2

     1. Comparative Example 1 
     (1) Preparation of the Granular Part of the Fimasartan 
     The granular part of the fimasartan of Comparative Example 1 was prepared to have the same weight per unit dosage form to Table 2. Fimasartan potassium trihydrate was put into the part of the microcrystalline cellulose and mixed for about two minutes, and sieved through a No. 30 mesh screen twice. Put the sieved mixture, the rest of the microcrystalline cellulose and part of the croscarmellose sodium in a high speed mixer and mixed for about three minutes. Binder solution was separately prepared by dissolving hydroxypropyl cellulose in purified water. The prepared binder solution was put into the high speed mixer, sieved through No. 20 mesh screen after wet granulation with a mixed solution, and dried. Fimasartan granules were prepared through putting the rest of the croscarmellose sodium in the dried granular part of the fimasartan and mixing in a double cone mixer for five minutes and supplementally mixing with the magnesium stearate for five minutes. 
     (2) Preparation of the Mixed Part of the Rosuvastatin 
     The tablet of Comparative Examples was prepared to have the same weight per unit dosage form to Table 2. Rosuvastatin calcium was put into the part of the lactose and mixed for about two minutes, and sieved through No. 30 mesh screen twice. Put the sieved mixture, the rest of the lactose, microcrystalline cellulose and the crospovidone (Comparative Example 1) in a double cone mixer and mixed for about three minutes. Magnesium stearate was added as a lubricant and supplementally mixed for about five minutes. 
     (3) Tablet Compression 
     The combination preparation was prepared by tableting with 20 kN of tableting pressure by using a rotary tablet compression machine (PICCOLA DC, RIVA) to have 249-251 mg of weight (250.0 mg of theoretical weight) and 9-10 kp of hardness per one tablet. Friability of the tablets obtained through the above process was measured by using a friability tester (25 rpm, 100 free falls). The measured friability was below 0.1% and thus hardness of the tablets was fine. 
     2. Comparative Example 2 
     Prepared Comparative Example 2 via the same preparation method explained in Comparative Example 1 with the compositions of Table 2 except an alteration of the disintegrant from crospovidone to croscarmellose sodium.

     As illustrated in the FIGURE, interference of fimasartan and rosuvastatin in Example 1 was remarkably low compared to the other formulations and thus it was shown that disintegration and dissolution were highly increased, and effects thereof was almost identical with the CRESTOR® on market as a single agent. However, disintegration and dissolution rates of Comparative Example wherein meglumine was not included were extremely low due to interference. 
     It is understood that the combination preparation of fimasartan and rosuvastatin including meglumine has superior bioavailability based on the above result.
