Description

신규한 텔미사르탄 아연염 및 그의 제조방법{The new Telmisartan zinc salt and the preparation thereof}The new telmisartan zinc salt and the preparation

본 발명은 안지오텐신 Ⅱ 길항제로서 고혈압 질환의 치료에 유용한 텔미사르탄 유리산의 물리화학적 성질이 개선된 텔미사르탄 아연염 및 그의 제조 방법에 관한 것이다.The present invention relates to telmisartan zinc salt with improved physicochemical properties of telmisartan free acid, which is useful as an angiotensin II antagonist for the treatment of hypertension diseases, and a method for preparing the same.

화합물 4′-[2-7-프로필-4-메틸-6-(1-메틸벤즈이미다졸-2-일)벤즈이미다졸-1-일메틸]비페닐-2-카복실산 (이하 ‘텔미사르탄’)은 유럽등록특허 제 502,314 호로부터 공지 되어 있고 하기와 같은 구조를 갖는다. Compound 4 ′-[2-7-propyl-4-methyl-6- (1-methylbenzimidazol-2-yl) benzimidazol-1-ylmethyl] biphenyl-2-carboxylic acid (hereinafter 'telmisartan ') Is known from EP 502,314 and has the following structure.

Figure 112008089655511-pat00001
Figure 112008089655511-pat00001

텔미사르탄은 이의 약리학적 특성에 의하여 고혈압 및 심부전 치료용, 허혈성 말초 순환 장애, 심근 허혈 치료용, 심근경색 후 심부전의 진행 예방용, 당뇨병성 신경병증, 녹내장 등의 치료용으로 사용할 수 있는 안지오텐신 길항제, 특히 안 지오텐신 Ⅱ 길항제임이 공지되어 있다. Telmisartan is angiotensin which can be used to treat hypertension and heart failure, to treat ischemic peripheral circulatory disorder, to treat myocardial ischemia, to prevent progression of heart failure after myocardial infarction, diabetic neuropathy, and glaucoma. It is known to be an antagonist, in particular an angiotensin II antagonist.

텔미사르탄은 베링거인겔하임에 의해 연구, 개발되어 미카르디스R와 미카르디스플러스R(히드로클로르치아지드와의 복합제)라는 상표로 미국, 일본, 유럽을 포함하여 전 세계 84개국에서 판매되고 있다. 또한, 텔미사르탄은 안지오텐신 II 수용체 차단제 중에서 가장 의욕적이며 광범위한 리서치 프로그램에 의해 연구되고 있으며, 현재 진행 중이거나 종료된 임상시험인 ONTARGET, PROTECTION, PROFESS에는 미카르디스의 심혈관 보호 효과를 연구하기 위해 58,000명이 넘는 환자들이 등록되어 있다. Telmisartan is researched and developed by Boehringer Ingelheim and sold in 84 countries around the world, including the United States, Japan, and Europe, under the trademarks of Mycardis R and Mycardis Plus R (combined with hydrochlorziazide). It is becoming. Telmisartan is also being studied by the most ambitious and extensive research program among angiotensin II receptor blockers. More than four patients are registered.

한편, 공업적인 생산에 있어서, 텔미사르탄 유리산은 매우 제한적인 용해성 때문에 텔미사르탄의 유리산으로 시판되는 형태의 제제는 수산화나트륨 등과 같은 강알카리화제를 직접적으로 텔미사르탄과 접촉시켜 제조되므로 제조공정이 위험할 뿐만 아니라, 연합시간에 따라 최종 제형의 품질 재현성이 달라지는 문제가 야기될 수 있다. 또한, 텔미사르탄 유리산의 고체 상태의 물리화학적 특성은 인체에 직접적으로 적용되기에 어려움이 있으므로, 현재 이에 대한 연구가 활발히 진행되고 있다. On the other hand, in industrial production, telmisartan free acid is prepared in the form of commercially available forms of telmisartan free acid because of its very limited solubility and is prepared by directly contacting a strong alkalizing agent such as sodium hydroxide with telmisartan. Not only is the process dangerous, it can also cause problems that the quality reproducibility of the final formulation depends on the association time. In addition, since the physicochemical characteristics of the solid state of telmisartan free acid are difficult to be applied directly to the human body, research on this is being actively conducted.

예를 들어, 국제공개특허 제 2003/037,876호, 국제공개특허 제 2006/044,754 호는 이러한 단점을 극복하기 위해 산 또는 염기가 부가된 부가 염 형태의 텔미사르탄 및 알칼리 금속 부형제를 함유한 텔미사르탄 제제가 개시되어 있다. For example, International Publication Nos. 2003 / 037,876 and 2006 / 044,754 disclose telmissars containing telmisartan and alkali metal excipients in addition salt form with an acid or base added to overcome this disadvantage. A burnt formulation is disclosed.

또한, 유럽등록특허 제1,144,386호, 국제공개특허 제2003/037,876호, 국제공개특허 제2006/050,509호 등에는 텔미사르탄 나트륨 염을 개시함으로써 텔미사르탄 유리산의 단점을 극복하고자 하였다.In addition, European Patent No. 1,144,386, International Publication No. 2003 / 037,876, International Publication No. 2006 / 050,509, and the like attempt to overcome the disadvantages of telmisartan free acid by incorporating telmisartan sodium salt.

그러나, 나트륨 섭취량의 변화가 고혈압 환자의 혈압에 민감한 영향을 미칠 수 있다는 점이 논의 되고 있는 상황에서, 텔미사르탄의 나트륨 염은 고혈압 치료시 또다른 문제점을 유발할 수 있다(Hypertension 27, 481-490, 1996). 일반적으로 나트륨의 추가적인 섭취는 혈관에 더 많은 유동체를 존재하게 하므로 심장으로 하여금 신체에 더 많은 혈액을 공급하게 한다. 또한 나트륨의 영향에 의한 혈관의 수축은 심장으로 들어가는 피의 양과 흐름을 저해하므로, 심장은 더 많은 혈액을 닫혀있는 인체의 순환 시스템에 공급해야 하므로, 나트륨은 혈압을 증가시킨다. However, in situations where changes in sodium intake can have a sensitive effect on blood pressure in hypertensive patients, the sodium salt of telmisartan may cause another problem in the treatment of hypertension (Hypertension 27, 481-490, 1996). In general, the additional intake of sodium causes more fluid to be present in the blood vessels, causing the heart to supply more blood to the body. In addition, the contraction of blood vessels under the influence of sodium inhibits the volume and flow of blood into the heart, so sodium increases blood pressure because the heart needs to supply more blood to the closed body's circulatory system.

따라서 텔미사르탄의 제제의 용이성만을 고려한다면 텔미사르탄의 나트륨염이 그 해결책에 근접할 수 있으나 상기의 내용과 같은 나트륨이 고혈압 환자에게 미칠 수 있는 영향을 고려한다면 텔미사르탄 나트륨 염이 고혈압 치료제로서 사용되기에는 안전성 측면에서 근본적으로 문제점을 내포하고 있음을 알 수 있다. Therefore, considering only the ease of preparation of telmisartan, the sodium salt of telmisartan may be close to the solution, but considering the effect of sodium on hypertension patients, the telmisartan sodium salt may be used to treat hypertension. It can be seen that there is a fundamental problem in terms of safety to be used as.

또한, 국제공개특허 제2006/050,921호, 유럽등록특허 제1,719,766호에는 텔미사르탄 마그네슘염과 칼슘염이 개시되어있다. 그러나, 텔미사르탄 마그네슘 및 칼슘염은 텔미사르탄 유리산 보다도 약제학적으로 매우 중요한 인습성 및 열에 대한 안정성이 결여되는 문제점을 내포하고 있다. In addition, International Patent Nos. 2006 / 050,921 and EP 1,719,766 disclose telmisartan magnesium salts and calcium salts. However, telmisartan magnesium and calcium salts suffer from the lack of pharmacologically important humidity and heat stability, which is more important than telmisartan free acid.

따라서 텔미사르탄 유리산의 단점인 인습성과 안정성을 포함하여 용해성, 고체 흐름성, 정전기성 등의 정제제형으로의 가공성을 개선하며 약학 조성물로서 적합한 고순도의 고품질을 가지는 텔미사르탄의 부가염이 요구되는 실정이다.Therefore, it is necessary to improve the processability of tablets such as solubility, solid flowability, and electrostaticity, including moisture and stability, which are disadvantages of telmisartan free acid, and an addition salt of telmisartan having high purity and high quality suitable as a pharmaceutical composition is required. It is a situation.

아연은 원소기호로 'Zn'이고, 원자번호는 30이며, 원자량은 65.39이다. 아연이 유용한 미네랄로 인식되기 시작한 것은 1950년대부터이다. ‘왜소증’ 및 ‘성선기능저하증’이 아연 결핍에 의한 것임이 밝혀지면서 아연의 중요성에 관심이 기울어지기 시작하였다. 미국에서는 1970년대 아연에 대한 섭취 권장량 설정되었고, 한국에서는 1995년에 처음으로 영양권장량이 제시되었다. 아연은 모든 동물조직에 존재하는 무기영양소의 하나로서 상피의 회복이나 전립선의 기능과도 관계가 있으며 피부나 골격의 발육, 유지에 필요한 필수 성분으로 핵산 합성과 단백질 합성에 필수요소라고 알려져 있다. 아연의 이러한 약리 작용을 이용한 의약품으로는 시판중인 인산아연(zinc sulfate)가 있다. 한국영양학회에서 2005년 발표한 한국인영양섭취기준에 의한 아연의 일일 권장 섭취량은 남자 성인 8~10mg, 여자성인 7~8mg, 임산부 10~11mg, 수유부 13mg등이며, 상한 섭취량은 남녀성인모두 35mg이다. 이러한 안전성으로 인하여 식품첨가물로는 글루콘산아연(zinc gluconate), 산화아연(zinc oxide) 등이 있으며 의약품부형제로는 스테아린산아연(zinc stearate) 등이 사용되고 있다.Zinc is an element symbol 'Zn', has an atomic number of 30 and an atomic weight of 65.39. Zinc began to be recognized as a useful mineral in the 1950s. Attention began to pay attention to the importance of zinc as it became clear that dwarfism and hypogonadism were due to zinc deficiency. In the United States, the recommended intake of zinc in the 1970s was set, and in 1995, the first recommended nutritional value was suggested in Korea. Zinc is one of the inorganic nutrients present in all animal tissues. It is also related to epithelial recovery and prostate function and is known to be essential for nucleic acid synthesis and protein synthesis. Drugs that take advantage of this pharmacological action of zinc include commercial zinc sulfate. The recommended daily intake of zinc according to the Korean Nutrition Intake Standard published by the Korean Nutrition Society in 2005 is 8-10mg for male adults, 7-8mg for female adults, 10-11mg for pregnant women, 13mg for lactating women, and 35mg for both men and women. . Due to such safety, food additives include zinc gluconate and zinc oxide, and zinc stearate is used as a pharmaceutical excipient.

이에 본 발명자들은 기존의 텔미사르탄 유리산이 지닌 문제점을 해결하고자 연구 노력한 결과 약제학적으로 매우 우수하며 안전성 측면에서도 뛰어난 텔미사르 탄 아연염을 개발하게 되었다. Accordingly, the present inventors have made efforts to solve the problems of the conventional telmisartan free acid, and thus telmisartan zinc salt has been developed very well in terms of pharmacy and safety.

본 발명은 안지오텐신 Ⅱ 길항제인 텔미사르탄 유리산의 단점이 개선되어 약제학적으로 우수하며 안전성이 뛰어난 신규 텔미사르탄 아연염 및 그의 제조방법을 제공하고자 한다. The present invention aims to provide a novel telmisartan zinc salt and a method for preparing the same, which are improved in the pharmacy and safety of the angiotensin II antagonist telmisartan free acid.

상기 목적에 따라, 본 발명은 약제학적으로 허용 가능하며 물리화학적 조건이 개선되어 고혈압 질환의 예방 또는 치료용 약제학적 조성물로서 매우 유용하게 사용될 수 있는 하기 화학식 1의 4'-[2-7로 표시되는 고순도의 텔미사르탄 아연염 을 제공한다:In accordance with the above object, the present invention is represented by 4 '-[2-7 of the general formula 1, which can be used as a pharmaceutical composition for the prevention or treatment of hypertension diseases with pharmaceutically acceptable and improved physicochemical conditions Provides high purity telmisartan zinc salt:

본 발명의 제조 방법에서, 아연화제는 수산화아연(zinc hydroxide), 아세트산아연(zinc acetate), 염화아연(zinc chloride), 브롬화아연(zinc bromide), 요오드화아연(zinc iodide) 등이 바람직하며, 텔미사르탄 유리산 1몰에 대하여 다양한 당량으로 사용가능하나 0.5 몰 이상인 것이 바람직하다. 이 때 반응 온도는 25℃ 내지 100℃이며, 염석출 온도는 -10 ℃ 내지 100 ℃이 바람직하다. In the production method of the present invention, the zincating agent is zinc hydroxide, zinc acetate, zinc chloride, zinc bromide, zinc iodide, zinc iodide, and the like. It can be used in various equivalents with respect to 1 mol of sartan free acid, but it is preferable that it is 0.5 mol or more. At this time, the reaction temperature is 25 ° C to 100 ° C, and the salt precipitation temperature is preferably -10 ° C to 100 ° C.

본 발명의 제조 방법에서, 유기 용매는 메탄올, 에탄올, 이소프로판올, 부탄올과 같은 저급알콜계; 1,4-디옥산, 테트라히드로퓨란, 디에틸에테르, 이소프로필에테르과 같은 에테르계; 디메틸포름아미드, 디에틸아세트아미드와 같은 아미드계; 아세톤, 메틸에틸케톤과 같은 케톤계; 이소프로필아세테이트와 같은 에스테르계; 클로로포름, 디클로로메탄과 같은 할로겐화 탄화수소계; 헥산, 헵탄, 옥탄과 같은 저급탄화수소계; 디메틸설폭시드 및 물 중에서 선택된 1종이상의 용매를 단독 또는 혼합 용매인 것이 바람직하다. In the production method of the present invention, the organic solvent is a lower alcohol type such as methanol, ethanol, isopropanol, butanol; Ethers such as 1,4-dioxane, tetrahydrofuran, diethyl ether and isopropyl ether; Amide systems such as dimethylformamide and diethylacetamide; Ketones such as acetone and methyl ethyl ketone; Esters such as isopropyl acetate; Halogenated hydrocarbon systems such as chloroform and dichloromethane; Lower hydrocarbons such as hexane, heptane and octane; At least one solvent selected from dimethyl sulfoxide and water is preferably used alone or as a mixed solvent.

본 발명의 텔미사르탄 아연염은 용해성이 좋고 안정하며 비흡습성이면서 고체의 비용적, 정전기성 등 물리화학적 특성이 공지의 텔미사르탄 유리염 등에 비하여 매우 개선된 특징을 가지므로 이를 포함하는 약학조성물이 고혈압 관련 질환의 치료 및 예방에 효과적으로 사용될 수 있다. The telmisartan zinc salt of the present invention is soluble, stable, non-hygroscopic, and the physical and chemical properties such as solid, cost-effective, electrostatic, etc. have very improved characteristics as compared to the known telmisartan free salt and the pharmaceutical composition comprising the same. It can be effectively used for the treatment and prevention of this hypertension related disease.

또한, 환자가 본 발명에 의한 텔미사르탄 아연염을 1일 최대복용량(텔미사르탄으로서 80mg)을 섭취하여도, 이에 따라 섭취되는 아연염은 불과 아연1일 권장섭취량 이하의 값인 5mg이다. 더욱이 아연 결핍증으로 인하여 고혈압이 유발될 수 있다는 최근 문헌보고 (Pediatr. Res. 58(4), 672, 2005) 를 고려하면 텔미사르탄 아연염이 고혈압에 잘 부합되는 염이라 할 수 있다. In addition, even if a patient ingests the telmisartan zinc salt according to the present invention in a maximum daily dose (80 mg as telmisartan), the zinc salt ingested accordingly is only 5 mg, which is a value less than the recommended daily intake of zinc. Furthermore, considering the recent literature (Pediatr. Res. 58 (4), 672, 2005) that zinc deficiency may cause hypertension, telmisartan zinc salt is a salt that is well-suited to hypertension.

그 결과, 상기 표에서 알 수 있듯이 비교예의 시료들은 텔미사르탄 염의 제조시 순도가 전혀 상승되지 않는 반면에 실시예 1~4에서 제조된 시료는 순도가 월등히 증가하는 탁월한 정제의 효과가 있음이 확인 되었다. 난용성으로 별도의 정제과정을 도입하는데 어려운 텔미사르탄 유리산 상태에서 실시예와 같이 부가염의 제조만으로도 약제학적으로 매우 적합한 고순도를 확보할 수 있음이 확인되었다.As a result, as can be seen from the table, the samples of Comparative Examples did not increase the purity at the time of the preparation of the telmisartan salt, while the samples prepared in Examples 1 to 4 was confirmed that the excellent purification effect is significantly increased It became. In the case of telmisartan free acid, which is difficult to introduce a separate purification process due to poor solubility, it was confirmed that only a preparation of the addition salt as in Example can secure a very high pharmacologically suitable high purity.

<< 실험예Experimental Example 2>  2> 침전성Precipitation 평가 evaluation

일반적으로 난용성 약물은 매질에 용해되더라도 그 용해성이 불량하면 다시 석출되어 침전되게 된다. 이것은 약물의 경구흡수를 감소시키는 요소가 될 수 있으므로 약물의 침전성 평가는 경구용 약물의 안정성 평가요소가 된다. 용출시험에서 일반적으로 사용되는 정제수 900mL의 매질과 1일 최대 상용량을 고려하여, 1mg/mL 의 메탄올로 용해시킨 텔미사르탄 유리산 및 실시예 1~4와 비교예 1~3에서 제조된 시료에 정제수를 넣어 0.1mg/mL이 되도록 수용액으로 제조하였다. 이후, 이들을 실온의 차광조건에 방치하여 처음 용기에 넣었을 때의 시료의 함량과 24시간 경과 후의 함량을 HPLC를 이용하여 측정하여 표 3에 기재하였다. In general, even poorly soluble drugs are precipitated and precipitated again if their solubility is poor even if they are dissolved in the medium. This may be a factor in reducing oral absorption of the drug, so the precipitation assessment of the drug is an evaluation of the stability of the oral drug. Considering the medium of 900 mL of purified water and the maximum daily capacity that are generally used in the dissolution test, telmisartan free acid dissolved in 1 mg / mL of methanol and the samples prepared in Examples 1 to 4 and Comparative Examples 1 to 3 Purified water was added to prepare an aqueous solution to 0.1mg / mL. Thereafter, these samples were left at room temperature to be shielded, and the contents of the sample when first placed in a container and after 24 hours were measured using HPLC, and are shown in Table 3 below.

그 결과, 시판중인 텔미사르탄 유리산은 대부분 침전되어 최초 상태의 약 5% 만이 남아 있었으나, 실시예1 및 3은 유리산에 비하여 월등하게 개선된 침전성을 나타내었다. 따라서, 본 발명의 텔미사르탄 아연염은 수용액상에서 용해성이 우수하고 수용액 상태에서 석출에 의한 침전발생이 매우 낮으므로 약물 흡수에 유리하다.As a result, commercially available telmisartan free acid was mostly precipitated, leaving only about 5% of the initial state, but Examples 1 and 3 showed significantly improved precipitation compared to free acid. Accordingly, the telmisartan zinc salt of the present invention is excellent in solubility in aqueous solution and very low in precipitation due to precipitation in aqueous solution, which is advantageous for drug absorption.

<실험예 3> 인습성 평가Experimental Example 3 Evaluation of Humidity

낮은 인습성은 화합물이 의약품 원료로 사용되기 위하여 요구되는 물성 중 실제 의약품의 가공 및 보관을 위한 매우 중요한 요소이다. 인습성을 측정하기 위하여 텔미사르탄 유리산 및 실시예 1~4, 비교예 1~3에서 제조된 각 시료를 진공건 조 (P2O5, 1일 이상)한 후, 칼피셔 법으로 초기 수분값을 측정한 후 인습성측정기기 (모델명: Hydrosorb 1000, 제조사: Quantachrome Instruments)를 이용하여 25℃ 및 상대습도 15, 35, 55, 75, 95%에서 인습된 수분량을 자동측정하여 표 4에 기재하였다. 단, 초기 수분값은 지속적으로 건조하여 더 이상 감량되지 않는 상태의 수분값으로 하였다.Low humidity is a very important factor for the processing and storage of the actual drug among the properties required for the compound to be used as a drug substance. In order to measure the humidity, telmisartan free acid and the samples prepared in Examples 1 to 4 and Comparative Examples 1 to 3 were vacuum-dried (P 2 O 5 , 1 day or more), followed by initial Karl Fischer method. After measuring the moisture value, the moisture content measured at 25 ° C and relative humidity of 15, 35, 55, 75, and 95% was measured automatically using a humidity measuring instrument (Model: Hydrosorb 1000, manufacturer: Quantachrome Instruments). Described. However, the initial moisture value was set to a moisture value in a state where it is continuously dried and no longer reduced.

그 결과, 텔미사르탄 유리산 및 실시예 1~2는 실험을 실시한 전 범위 상대습도에서 약 0.5%의 매우 낮은 인습성을 나타내어 공기 중 수분에 원료가 노출되더라도 안정하게 보관될 수 있음을 알 수 있다. 반면, 비교예 1~3에서 제조된 각 시료들은 상대습도가 증가할수록 기하급수적으로 공기 중 수분을 인습하여 약제학 용도의 원료로서 매우 불량한 특성을 가지고 있었다. 특히 텔미사르탄은 식약청의 원료의약품 기준에 의하면 1% 미만의 수분을 가지도록 관리되어야 하며 그 이상의 수분은 원료로서 사용될 수 없도록 규제되고 있음을 감안하면 비교예 1~3에서 제조된 시료는 제제화하기에는 너무나 큰 인습성을 가지고 있음이 확인되었다. 이와는 달리 본 발명의 텔미사르탄 아연염은 통상적인 상대습도의 공기 중에 노출되더라도 인습되지 않는 우수한 비흡습성(비인습성) 특성을 가짐이 확인되었다.As a result, it can be seen that telmisartan free acid and Examples 1 to 2 exhibit very low humidity of about 0.5% in the entire range of relative humidity in which the experiment was conducted, so that even if the raw material is exposed to moisture in the air, it can be stably stored. have. On the other hand, each of the samples prepared in Comparative Examples 1 to 3 had very poor properties as a raw material for pharmaceutical use as the relative humidity increases the moisture in the air exponentially. In particular, telmisartan should be managed to have a water content of less than 1% according to the KFDA's drug substance standards, and more water is regulated so that it cannot be used as a raw material. It has been confirmed that it has too high a convention. On the contrary, it was confirmed that the telmisartan zinc salt of the present invention has excellent non-hygroscopicity (non-hygroscopicity) characteristics that are not condensed even when exposed to air at normal relative humidity.

그 결과, 실시예 1~4에서 제조된 시료가 텔미사르탄 유리산 및 비교예 1~3의 시료에 비하여 정전기성을 감소시켜 기기마찰을 고려한 가공성이 우수함을 확인하였다. As a result, it was confirmed that the samples prepared in Examples 1 to 4 have excellent electrolytic properties compared to telmisartan free acid and the samples of Comparative Examples 1 to 3, thereby being excellent in workability considering device friction.

<< 실험예Experimental Example 7> 비용적(단위 중량당 부피) 시험 7> Cost-effective (volume per unit weight) test

일반적으로 화합물을 약품의 원료로 사용하여 정제로 가공시 고체의 비용적(동일한 단위 중량당 부피)은 공정상 편의성 및 제형의 크기에 영향을 줄 수 있고, 비용적이 클 경우, 가공성이 매우 불량한 문제를 야기할 수 있다. 따라서 본 발명의 염의 저비용적을 확인하기 위해, 텔미사르탄 유리산과 실시예 1~4 및 비교예 1~3에서 제조된 시료를 메스실린더에 넣고 수직으로 10cm의 높이에서 20차례 이상 태핑하여 압축이 충분히 이뤄지도록 반복하여 자연낙하시켰다. 태핑을 실시하기 전후로 구분하여 그 비용적을 측정하여 표 7에 기재하였다. In general, the cost (solid volume per unit weight) of solids may affect process convenience and formulation size when processed into tablets using the compound as a raw material for pharmaceuticals. May cause. Therefore, in order to confirm the low cost of the salt of the present invention, the telmisartan free acid and the samples prepared in Examples 1 to 4 and Comparative Examples 1 to 3 were put in a measuring cylinder and tapped 20 times or more at a height of 10 cm vertically to sufficiently compress. The natural drop was repeated to achieve this. Before and after the tapping, the cost is measured and the results are shown in Table 7.

텔미사르탄 유리산 및 비교예 1~3에 비하여 실시예 1~4의 시료는 월등한 비용적 감소효과를 나타내었다. 일반적으로 분말성상의 의약품 원료는 비용적이 높아 항상 압축성형된 이후, 인체에 투약이 가능한 제형(정제나 캡슐제)로 설계되므로 비용적이 큰 경우, 약제학적인 가공성이 매우 떨어지게 된다. 따라서 본 발명의 텔미사르탄 아연염은 약제학적 가공성이 우수한 물리화학적 특징을 가진다.Compared with telmisartan free acid and Comparative Examples 1-3, the sample of Examples 1-4 showed the outstanding cost reduction effect. In general, pharmaceutical raw materials in powder form have high cost and are always compression molded, so that they are designed as dosage forms (tablets or capsules) that can be administered to the human body. Accordingly, the telmisartan zinc salt of the present invention has a physicochemical characteristic excellent in pharmaceutical processability.
