Abstract
Description
本発明は、保存安定性が向上されたカンデサルタン シレキセチル製剤に関する。 The present invention relates to a candesartan cilexetil formulation with improved storage stability.
カンデサルタン シレキセチル（Ｃａｎｄｅｓａｒｔａｎ Ｃｉｌｅｘｅｔｉｌ）は、持続性アンジオテンシンＩＩ受容体拮抗作用を有し、高血圧症、腎実質性高血圧症、並びに軽症〜中等症の慢性心不全の治療薬として広く本邦において使用されている。（特許文献１）
ところで、結晶性のカンデサルタン シレキセチルは、それ自体は温度、湿度、光に対して安定であるが、錠剤化した場合、製造工程における圧力、摩擦、熱等により結晶の歪みが生じ、これにより、経日的な分解物増加、含量低下が加速される旨の報告がなされている。（特許文献２）
特許文献２では、ポリエチレングリコール６０００、ステアリールアルコール、ショ糖脂肪酸エステル及びソルビタン脂肪酸エステル等の低融点油脂状物質を配合することで、顕著に有効成分であるカンデサルタン シレキセチルの分解が抑えられ、錠剤の保存安定性が向上した旨、報告している。
一方、特許文献３では、錠剤化の間の劣化に対しカンデサルタン シレキセチルを適切に安定化させる目的でカラゲナンを配合した医薬組成物を報告している。
また、特許文献４では、非イオン性界面活性剤を含んで成る生物学的利用能が改善されたカンデサルタン シレキセチル製剤を報告している。
このように製剤を安定化することは、製品の品質担保に非常に重要であり、製品価値を高めることにも繋がる。
Candesartan cilexetil has a persistent angiotensin II receptor antagonistic action and is widely used in Japan as a therapeutic agent for hypertension, renal parenchymal hypertension, and mild to moderate chronic heart failure. (Patent Document 1)
By the way, crystalline candesartan cilexetil itself is stable to temperature, humidity, and light, but when tableted, crystal distortion occurs due to pressure, friction, heat, etc. in the manufacturing process. It has been reported that daily degradation products increase and content decrease are accelerated. (Patent Document 2)
In Patent Document 2, by blending a low melting point oily substance such as polyethylene glycol 6000, stearyl alcohol, sucrose fatty acid ester and sorbitan fatty acid ester, decomposition of candesartan cilexetil, which is an active ingredient, is remarkably suppressed, Reports that storage stability has been improved.
On the other hand, Patent Document 3 reports a pharmaceutical composition containing carrageenan for the purpose of appropriately stabilizing candesartan cilexetil against deterioration during tableting.
Patent Document 4 reports a candesartan cilexetil preparation with improved bioavailability comprising a nonionic surfactant.
Stabilizing the preparation in this way is very important for quality assurance of the product and leads to an increase in product value.
本発明の課題は保存安定性が向上されたカンデサルタン シレキセチル製剤を提供することにある。 An object of the present invention is to provide a candesartan cilexetil preparation with improved storage stability.
本発明者らは結晶性のカンデサルタン シレキセチルにクエン酸トリエチル、カルナウバロウ及びラウリル硫酸ナトリウムから選択された添加物を配合することで、カンデサルタン シレキセチルの分解が抑えられ、保存安定性が向上した錠剤が得られることを見出し、本発明を完成した。
即ち、本発明は 結晶性のカンデサルタン シレキセチル又はその塩にクエン酸トリエチル、カルナウバロウ及びラウリル硫酸ナトリウムから選択された添加物を配合した経口用固形医薬組成物に関する。
また、本発明は、結晶性のカンデサルタン シレキセチル又はその塩にクエン酸トリエチル、カルナウバロウ及びラウリル硫酸ナトリウムから選択された添加物を配合した錠剤の製造法に関する。
The inventors of the present invention blended crystalline candesartan cilexetil with an additive selected from triethyl citrate, carnauba wax and sodium lauryl sulfate, whereby the decomposition of candesartan cilexetil is suppressed, and a tablet with improved storage stability is obtained. As a result, the present invention has been completed.
That is, the present invention relates to an oral solid pharmaceutical composition comprising crystalline candesartan cilexetil or a salt thereof and an additive selected from triethyl citrate, carnauba wax and sodium lauryl sulfate.
The present invention also relates to a method for producing a tablet in which crystalline candesartan cilexetil or a salt thereof is blended with an additive selected from triethyl citrate, carnauba wax and sodium lauryl sulfate.
