Description
本発明は、カルシウム拮抗薬及びアンジオテンシンＩＩ受容体拮抗薬を有効成分として含む医薬製剤の製造方法に関する。 The present invention relates to a method for producing a pharmaceutical preparation comprising a calcium antagonist and an angiotensin II receptor antagonist as active ingredients.
高血圧とは、血圧が正常範囲よりも持続的に高くなっている状態をいう。高血圧は生活習慣病の１つであり、高血圧状態が持続されると、動脈硬化症や、虚血性心疾患、脳卒中などを発症することがある。
現在、高血圧患者の治療には、高血圧治療薬（降圧剤）を用いた血圧コントロールが広く一般に行われている。高血圧治療薬としては、カルシウム拮抗薬（ＣＣＢ）、アンジオテンシン交換酵素阻害薬、アンジオテンシンＩＩ受容体拮抗薬（ＡＲＢ）等が一般に使用されている。High blood pressure refers to a state in which blood pressure is continuously higher than the normal range. High blood pressure is one of lifestyle-related diseases, and arteriosclerosis, ischemic heart disease, stroke, etc. may develop if the hypertensive state persists.
Currently, blood pressure control using antihypertensive drugs (hypertensive agents) is widely used for the treatment of hypertensive patients. As antihypertensive drugs, calcium antagonists (CCB), angiotensin exchange enzyme inhibitors, angiotensin II receptor antagonists (ARB) and the like are generally used.
カルシウム拮抗薬（ＣＣＢ）は、イオンチャネルを介した細胞内へのＣａ2+の取り込みを抑制し、平滑筋の収縮を減弱化させることにより、降圧作用を奏することが知られている。カルシウム拮抗薬は、現在、日本で最も汎用されている降圧薬であり、重篤な副作用が少ないこと、利尿薬に次いで安価であることから第一選択薬として勧められている。
アンジオテンシンＩＩ受容体拮抗薬（ＡＲＢ）は、アンジオテンシンＩＩ受容体に対して特異的に拮抗することにより、レニン・アンジオテンシン系で産生されて強い昇圧作用を持つアンジオテンシンＩＩの生理作用を抑制し、降圧作用を奏することが知られている。Calcium antagonists (CCB) are known to exert a hypotensive effect by suppressing the uptake of Ca 2+ into cells via ion channels and attenuating the contraction of smooth muscle. Calcium antagonists are currently the most widely used antihypertensive drugs in Japan, and are recommended as first-line drugs because they have few serious side effects and are inexpensive after diuretics.
Angiotensin II receptor antagonist (ARB) suppresses the physiological action of angiotensin II produced in the renin-angiotensin system and having a strong pressor action by specifically antagonizing the angiotensin II receptor, and has a hypotensive action. It is known to play.
このように、カルシウム拮抗薬とアンジオテンシンＩＩ受容体拮抗薬とは、異なる機序により降圧作用をもたらす。したがって、単剤投与で症状の改善があまりみられない高血圧患者に対しては、治療効果を高める目的で、カルシウム拮抗薬とアンジオテンシンＩＩ受容体拮抗薬とを併用することも試みられている（特許文献１）。 Thus, calcium antagonists and angiotensin II receptor antagonists have antihypertensive effects by different mechanisms. Therefore, for hypertensive patients whose symptoms do not improve much with single-agent administration, it has been attempted to use a calcium antagonist and an angiotensin II receptor antagonist together for the purpose of enhancing the therapeutic effect (patent) Reference 1).
しかしながら、カルシウム拮抗薬及びアンジオテンシンＩＩ受容体拮抗薬の原薬は、いずれも水への溶解度が低く、原薬を投与しても効果が表れるまで時間がかかるという問題がある。例えば、カルシウム拮抗薬の１つであるシルニジピンは、２０℃での水への溶解度が数ｎｇ／ｍＬであり、アンジオテンシンＩＩ受容体拮抗薬の１つであるバルサルタンは、２０℃での水への溶解度が０．１７ｍｇ／ｍＬ程度である。そのため、現在市販されているカルシウム拮抗薬製剤及びアンジオテンシンＩＩ受容体拮抗薬製剤は、溶出速度が大きくなるようそれぞれ工夫がなされている。
しかしながら、市販のカルシウム拮抗薬製剤と、アンジオテンシンＩＩ受容体拮抗薬製剤は、それぞれ別個の方法で溶出速度を向上させているため、１つの医薬製剤（配合剤）で両者の溶出プロファイルを実現することは難しい。However, both the calcium antagonist and the angiotensin II receptor antagonist drug substance have low solubility in water, and there is a problem that it takes time until the drug substance is administered even if the drug substance is administered. For example, cilnidipine, one of the calcium antagonists, has a water solubility of several ng / mL at 20 ° C., and valsartan, one of the angiotensin II receptor antagonists, is water-soluble at 20 ° C. The solubility is about 0.17 mg / mL. Therefore, the calcium antagonist preparation and the angiotensin II receptor antagonist preparation currently on the market have been devised to increase the elution rate.
However, since the commercial calcium antagonist preparation and the angiotensin II receptor antagonist preparation improve the dissolution rate by different methods, respectively, both dissolution profiles should be realized with one pharmaceutical preparation (compound). Is difficult.
本発明は、上記問題点に鑑みてなされたものであり、市販のカルシウム拮抗薬製剤及びアンジオテンシンＩＩ受容体拮抗薬製剤それぞれの溶出プロファイルに近い溶出プロファイルを実現できる医薬製剤（配合剤）の製造方法を提供することを目的とする。 The present invention has been made in view of the above problems, and a method for producing a pharmaceutical preparation (compound) capable of realizing an elution profile close to the elution profile of each of a commercially available calcium antagonist preparation and an angiotensin II receptor antagonist preparation The purpose is to provide.

The method of granulating without using can be mentioned. After granulation, for example, the particles may be sized using a sizing machine and dried using a fluidized bed dryer. By the above method, a mixture containing calcium antagonist-containing granules and angiotensin II receptor antagonist-containing granules can be obtained.

For Examples 1 and 2 and Comparative Example 1, one tablet was used, and for Example 3 and Comparative Example 2, two tablets were used.
［試験例４］
シルニジピンの溶出試験については、第十六改正日本薬局方の項に記載されている溶出試験法（パドル法）に従い、毎分５０回転、試験液として０．１ｗ／ｖ％ポリソルベート８０を添加した溶出試験第２液９００ｍＬを用い、試験を行った。試験開始から７分、９０分後の試験液を採取し、液体クロマトグラフィーにより試験を行い、シルニジピンの溶出率を算出した。
なお、実施例１、２及び比較例１については、１錠を用い、実施例３及び比較例２については２錠を用いて実施した。[Test Example 4]
For the dissolution test of cilnidipine, in accordance with the dissolution test method (paddle method) described in the 16th revised Japanese Pharmacopoeia section, dissolution at 50 rpm, 0.1 w / v% polysorbate 80 was added as a test solution. The test was conducted using 900 mL of the second test liquid. Test solutions 7 and 90 minutes after the start of the test were collected and tested by liquid chromatography to calculate the elution rate of cilnidipine.
For Examples 1 and 2 and Comparative Example 1, one tablet was used, and for Example 3 and Comparative Example 2, two tablets were used.
＜結果＞
バルサルタンの粒度を測定した結果、実施例１〜３、比較例１〜３に使用したバルサルタンの粒度は、すべてＤ９０が２０μｍ以下であった。
実施例１のシルニジピン顆粒及びシルニジピン・バルサルタン配合顆粒について、試験例２に従い粒度分布を測定した。その結果を表１１に記載する。<Result>
As a result of measuring the particle size of valsartan, the particle size of valsartan used in Examples 1 to 3 and Comparative Examples 1 to 3 was all D90 of 20 μm or less.
The particle size distribution of the cilnidipine granule and the cilnidipine valsartan combination granule of Example 1 was measured according to Test Example 2. The results are listed in Table 11.
実施例１〜３、比較例１〜３にて作成し錠剤を試験例３及び４に従い溶出率を確認した。その結果を表１２に記載する。
なお、シルニジピンの市販製剤であるアテレック（登録商標）錠及びバルサルタンの市販製剤であるディオバン（登録商標）錠の溶出速度を考慮して基準値を設定し、シルニジピン、バルサルタンそれぞれの溶出率が基準値を満たすものを○、満たさないものを×と評価した。
その結果、実施例１〜３については、すべて基準値内の溶出率となったが、比較例１〜３については、基準値内の溶出率が得られなかった。The elution rate was confirmed according to Test Examples 3 and 4 prepared in Examples 1-3 and Comparative Examples 1-3. The results are listed in Table 12.
The reference values were set in consideration of the dissolution rate of Atelec (registered trademark) tablets, which are commercially available cilnidipine and Diovan (registered trademark) tablets, which are commercially available valsartan, and the dissolution rates of cilnidipine and valsartan are the reference values What satisfy | filled satisfy | filled (circle) and evaluated what was not satisfied as x.
As a result, for Examples 1 to 3, the elution rate was within the reference value, but for Comparative Examples 1 to 3, the elution rate within the reference value was not obtained.
本発明の方法により製造された医薬製剤は、カルシウム拮抗薬の溶出速度を高め、市販のカルシウム拮抗薬製剤及びアンジオテンシンＩＩ受容体拮抗薬製剤それぞれの溶出プロファイルに近い溶出プロファイルを実現することができる。したがって、産業上極めて有用である。 The pharmaceutical preparation produced by the method of the present invention can increase the dissolution rate of the calcium antagonist, and can realize an elution profile close to that of the commercially available calcium antagonist preparation and the angiotensin II receptor antagonist preparation. Therefore, it is very useful industrially.
