Description

本発明は、オルメサルタンメドキソミルを含む打錠障害が少なく良好な溶出性を示す錠剤に関する。  The present invention relates to a tablet containing olmesartan medoxomil and exhibiting good dissolution properties with little tableting trouble.

プロドラックであるオルメサルタンメトキソミルは、経口投与後活性代謝物であるオルメサルタンに変換される。オルメサルタンは血圧の上昇に関与するAT1(AIIタイプ1)受容体に選択的に作用してAIIの結合を競合的に阻害し、血管組織レベルにおいてAT1受容体を介したAIIの血管収縮反応を非克服性(insurmountable)に抑制することにより降圧作用を発現する。  Olmesartan methoxomil, a prodrug, is converted to olmesartan, an active metabolite, after oral administration. Olmesartan selectively acts on the AT1 (AII type 1) receptor involved in the increase in blood pressure to competitively inhibit AII binding, and does not inhibit the vasoconstrictive response of AII via the AT1 receptor at the vascular tissue level. The antihypertensive effect is expressed by suppressing it in an insurmountable manner.

オルメサルタンメドキソミル錠は、原薬オルメサルタンメドキソミルの弱酸性から中性領域での溶解性は極めて低いため、溶出性改善のために原薬の粉砕工程が製造工程中に必要となる。  Since olmesartan medoxomil tablets have extremely low solubility from the weakly acidic to neutral range of the drug substance olmesartan medoxomil, the drug substance pulverization process is required during the manufacturing process in order to improve dissolution.

これまでにも、オルメサルタンメドキソミル錠の溶出を高める試みとして、例えば、特許文献1には、薬剤からの溶出性がコントロールされたオルメサルタンメドキソミル含有製剤として、90%粒子径が75μm以下であることを特徴とするオルメサルタンメドキソミル、当該粒子径のオルメサルタンメドキソミルを使用するオルメサルタンメドキソミル含有製剤の製造方法が記載されている。  So far, as an attempt to enhance the dissolution of olmesartan medoxomil tablets, for example, Patent Document 1 is characterized in that a 90% particle size is 75 μm or less as an olmesartan medoxomil-containing preparation with controlled dissolution from a drug. And a method for producing an olmesartan medoxomil-containing preparation using the olmesartan medoxomil having the above particle size.

また、特許文献2には、溶出性を低下させると考えられていた組成物を圧縮する工程を採用することにより、むしろ溶出性が改善されることを見出し、組成物を圧縮する打錠工程を含むことを特徴とするオルメサルタンメドキソミル含有錠剤(但し、結晶セルロース又はトウモロコシデンプンを含有する錠剤を除く)の溶出性改善方法であって、前記打錠工程が、60−400N/mmの圧力を使用する工程であり、ステアリン酸マグネシウムを除く成分を混合した後、ステアリン酸マグネシウムを加えて混合した組成物を打錠する工程である方法が記載されている。In addition, Patent Document 2 finds that dissolution is improved by adopting a step of compressing a composition that was thought to reduce dissolution, and a tableting step of compressing the composition. A method for improving dissolution of tablets containing olmesartan medoxomil (excluding tablets containing crystalline cellulose or corn starch), wherein the tableting step uses a pressure of 60 to 400 N / mm 2 A method is described in which a component excluding magnesium stearate is mixed, and then a composition in which magnesium stearate is added and mixed is tableted.

しかしながら、粉砕した原薬を用いて錠剤とするだけではなく、更なる溶出性改善のための手段は、他に報告されていない。  However, there are no other reports on the means for further improving dissolution, in addition to tableting using the pulverized drug substance.

(試験例1)
オルメサルタンメドキソミル40mg錠の溶出率の測定
日本薬局方第16改正に記載される溶出試験法第2法(パドル法)に従い、毎分50回転、試験液として水900mLを用い、1ベッセルあたり1錠のオルメサルタンメドキソミル40mg錠を添加し試験を行った。試験開始から120分後の試験液を採取し、0.45μm孔径のメンブランフィルターを用いて濾過し、吸光度測定法によりオルメサルタンメドキソミルの溶出率を測定した。溶出率の算出は、「257nmにおける濾液の吸光度−338nmにおける濾液の吸光度」を基に算出した。
(Test Example 1)
Measurement of dissolution rate of olmesartan medoxomil 40 mg tablets According to the dissolution test method method 2 (paddle method) described in the 16th revision of the Japanese Pharmacopoeia, 50 revolutions per minute, using 900 mL of water as the test solution, 1 tablet per vessel An olmesartan medoxomil 40 mg tablet was added for testing. A test solution 120 minutes after the start of the test was collected and filtered using a membrane filter having a pore diameter of 0.45 μm, and the dissolution rate of olmesartan medoxomil was measured by an absorbance measurement method. The elution rate was calculated based on “absorbance of the filtrate at 257 nm—absorbance of the filtrate at 338 nm”.

Figure 2017008018
Figure 2017008018

APIの粒子径に関わらず、StMgの含量に応じて溶出率が高くなる傾向を示した。平均粒子径が約2.6μmでは、StMg含有率/API含有率が5%以上あれば目標としていた120分で25%以上の溶出率を示すことが認められた。更には、StMg含有率/API含有率(%)と120分における溶出率(%)には、図1に示したように相関関係が認められた。  Regardless of the particle size of the API, the elution rate tended to increase with the StMg content. When the average particle size was about 2.6 μm, it was found that if the StMg content / API content was 5% or more, the dissolution rate was 25% or more in 120 minutes, which was the target. Furthermore, as shown in FIG. 1, a correlation was found between the StMg content / API content (%) and the elution rate (%) at 120 minutes.

一方、平均粒子径が約4.0μmでは、StMg含有率/API含有率が8%以上でないと120分で25%以上の溶出率とならないことが認められた。  On the other hand, when the average particle size was about 4.0 μm, it was found that the dissolution rate of 25% or more was not achieved in 120 minutes unless the StMg content / API content was 8% or more.
