Abstract
Description
本発明は、イルベサルタンを含有する医薬組成物に関する。 The present invention relates to a pharmaceutical composition containing irbesartan.
イルベサルタンは、化学名が2−ブチル−3−{4−[2−(1H−テトラゾール−5−イル)フェニル]ベンジル}−1,3−ジアザスピロ[4.4]ノン−1−エン−4−オンと記される長期作用性アンギオテンシンII受容体拮抗剤である。特に高血圧症等の治療に有用である。 Irbesartan has the chemical name 2-butyl-3- {4- [2- (1H-tetrazol-5-yl) phenyl] benzyl} -1,3-diazaspiro [4.4] non-1-ene-4- It is a long acting angiotensin II receptor antagonist marked ON. It is particularly useful for the treatment of hypertension and the like.
前記イルベサルタンを含有する医薬組成物としては、(a)約20〜約70重量%のイルベサルタン;(b)約1〜約70重量%の希釈剤;(c)約2〜約20重量%の結合剤;(d)約1〜約10重量%の崩壊剤;(e)約0.1〜約5重量%の抗付着剤;及び(f)約0.2〜約5重量%の滑沢剤を含有する医薬組成物が提案されている(例えば、特許文献1参照)。 The pharmaceutical composition containing the irbesartan includes (a) about 20 to about 70% by weight irbesartan; (b) about 1 to about 70% by weight diluent; (c) about 2 to about 20% by weight binding. (D) about 1 to about 10% by weight disintegrant; (e) about 0.1 to about 5% by weight anti-adhesive; and (f) about 0.2 to about 5% by weight lubricant. Has been proposed (see, for example, Patent Document 1).
しかしながら、前記イルベサルタンは、綿毛状の物質であり、相対的に実質重量が少なく、密度も非常に小さい。また、好ましくない流動特性を有する。これらの特性により、イルベサルタンを高含有する製剤では、打錠時に粉末の流動性不良が引き起こされ、得られる製剤の重量の均一性の保証が困難となるという問題がある。 However, the irbesartan is a fluffy substance, has a relatively small substantial weight, and a very low density. It also has undesirable flow characteristics. Due to these characteristics, in the preparation containing a high amount of irbesartan, there is a problem that poor flowability of the powder is caused at the time of tableting, and it is difficult to guarantee the uniformity of the weight of the resulting preparation.
したがって、イルベサルタンを高含有量としつつ、打錠時の粉末の流動性に優れ、得られる製剤の重量のばらつきを低減することができるイルベサルタン含有医薬組成物は、未だ提供されておらず、その速やかな提供が強く求められているのが現状である。 Therefore, an irbesartan-containing pharmaceutical composition that has a high content of irbesartan, is excellent in fluidity of the powder at the time of tableting, and can reduce variation in the weight of the resulting preparation has not yet been provided. The current situation is that there is a strong demand for such provision.
本発明は、従来における前記諸問題を解決し、以下の目的を達成することを課題とする。即ち、本発明は、イルベサルタンを高含有量としつつ、打錠時の粉末の流動性に優れ、得られる製剤の重量のばらつきを低減することができるイルベサルタン含有医薬組成物を提供することを目的とする。 An object of the present invention is to solve the above-described problems and achieve the following objects. That is, the present invention aims to provide an irbesartan-containing pharmaceutical composition that has a high content of irbesartan, has excellent powder flowability during tableting, and can reduce variation in the weight of the resulting preparation. To do.
前記課題を解決するための手段としては、以下の通りである。即ち、
<1> イルベサルタンの含有量が、45重量%以上であり、
前記イルベサルタンの平均粒子径(D50)が、8μm未満であることを特徴とするイルベサルタン含有医薬組成物である。
<2> イルベサルタンの含有量が、65重量%超である前記<1>に記載のイルベサルタン含有医薬組成物である。
<3> イルベサルタンの含有量が、65重量%超、75重量%以下である前記<1>から<2>のいずれかに記載のイルベサルタン含有医薬組成物である。
<4> イルベサルタンの平均粒子径(D50)が、2μm〜7μmである前記<1>から<3>のいずれかに記載のイルベサルタン含有医薬組成物である。
<5> イルベサルタンの平均粒子径(D50)が、3μm〜6μmである前記<1>から<4>のいずれかに記載のイルベサルタン含有医薬組成物である。
<6> イルベサルタン含有医薬組成物が粉末であり、前記粉末の安息角が50°以下である前記<1>から<5>のいずれかに記載のルベサルタン含有医薬組成物である。
Means for solving the problems are as follows. That is,
<1> The content of irbesartan is 45% by weight or more,
The irbesartan-containing pharmaceutical composition, wherein the irbesartan has an average particle size (D50) of less than 8 μm.
<2> The irbesartan-containing pharmaceutical composition according to <1>, wherein the content of irbesartan is more than 65% by weight.
<3> The irbesartan-containing pharmaceutical composition according to any one of <1> to <2>, wherein the content of irbesartan is more than 65% by weight and 75% by weight or less.
<4> The irbesartan-containing pharmaceutical composition according to any one of <1> to <3>, wherein the average particle size (D50) of irbesartan is 2 μm to 7 μm.
