Abstract
Description
腸溶性コーティングは、主として酸に不安定な薬剤を胃酸から保護する一方、胃壁に対して刺激又は障害を与える薬剤から胃粘膜を保護する等の様々な目的で広く使用されてきた。有効成分とアルカリ成分を含有し、腸溶性被覆剤でコーティングした錠剤が多々知られている(特許文献1~17)。また、腸溶性被覆剤としてメタクリル酸コポリマーを使用することは公知であり、該メタクリル酸コポリマーはオイドラギット(EUDRAGIT(登録商標);エボニックインダストリーズAG社製)ポリマーとして市販されており、腸溶性被覆基材としてアルカリ成分である重曹がポリマーの分散性向上の目的で予め配合されたAcryl-EZE(カラコン社製)も市販されている。そして、腸溶性被覆剤中の滑沢剤として通常、タルクが使用されること、またタルクの含量がポリマー成分に対して重量比50%が好ましいことが知られている(非特許文献1)。

以下に本発明を詳細に説明する。
本明細書中、「腸溶性錠剤」とは、有効成分を含有する核を、腸溶性ポリマーを含む腸溶性被覆基材で被覆した錠剤を意味する。本発明では好ましくは、有効成分を含有する核を、腸溶性ポリマーを含む腸溶性被覆基材で被覆した腸溶性の錠剤(腸溶性錠剤)が提供される。以下、本発明の腸溶性錠剤を本発明錠剤とも称する場合がある。
本明細書中、腸溶性錠剤における、腸溶性被覆基材で構成される層を、腸溶性被覆層と称する。
腸溶性ポリマーのコーティング量は有効成分を含有する核の大きさや、形状等によっても異なるが、核を錠剤とする場合には、通常、耐酸性及び崩壊性の観点から、核の表面積との換算で4~8、好ましくは、4~6mg/cm2程度である。
40%を超えるとタルクが均一に分散せず、錠剤の製造性に問題が生じる。また、滑沢剤として機能するには10%程度はタルクを含むことが好ましい。分散性の観点から、該タルクは、上記ポリマー成分に対して、好ましくは重量比10~25%の重量で含められる。このようなタルクの使用量は、通常当分野で用いられている、あるいは推奨されている量に比べて有意に少ない。
腸溶性被覆層中、タルクは不溶成分として分散しているため、量が少なく粒子径が小さいほど膜の水分透過性を低下させ、耐酸性の向上が期待できる。さらに腸溶性被覆基材の調製時にタルクは分散状態であるため、タルク量が少なく、粒子径が小さい程分散状態は向上し、コーティング工程中のタルクの沈降を防ぎ、均一な腸溶性被覆層の膜を形成することができる。
また、タルクに加え、他の滑沢剤を含めることができ、そのような滑沢剤として、例えばステアリン酸マグネシウム、ショ糖脂肪酸エステル、ポリエチレングリコール、ステアリン酸等が挙げられる。
ここで、「アルカリ成分を実質的に含有しない」とは、アルカリ成分を配合しないことを意味し、耐酸性や崩壊性、有効成分の溶出性等の錠剤特性に影響を及ぼさないような微量のアルカリ成分の有無は問わない。
本明細書における「有効成分」は、国際公開第2003/029232号パンフレットに記載の4-[2-(4-メチルフェニルスルファニル)フェニル]ピペリジンまたはその塩である。
(1)有効成分を含有する核錠
本発明において腸溶性被覆基材によるコーティングを施す核錠は、有効成分、賦形剤、ならびに結合剤を用いて造粒および整粒し、得られた整粒末に崩壊剤および滑沢剤を混合し、打錠することにより得ることができる。これらの賦形剤、結合剤、崩壊剤および滑沢剤としては、錠剤の製造に慣用されているものを用いればよい。また、造粒、整粒、混合、および打錠の各工程は慣用の方法により行うことができる。
コーティングに用いる腸溶性被覆基材は上記した通りである。腸溶性被覆基材は、腸溶性ポリマー及びタルクを有機溶剤に溶解して用いるか又は水性ラテックスあるいは水分散液としてコーティングに用いることができる。必要に応じて可塑剤を用いてもよい。更には、ポリマーとタルクの混合粉末を直接核錠に噴霧供給し同時に可塑剤をスプレーする乾式コーティングを行ってもよい。
中間被覆層用のコーティング物質としては、例えば、低置換度ヒドロキシプロピルセルロース、ヒドロキシプロピルセルロース、ヒドロキシプロピルメチルセルロース(ヒプロメロース、例えば、TC-5等)、ポリビニルピロリドン、ポリビニルアルコール、メチルセルロース、ヒドロキシエチルメチルセルロース等の高分子基材に、ショ糖〔精製白糖(粉砕したもの(粉糖)や粉砕しないもの)等〕、コーンスターチ等の澱粉糖、乳糖、蜂蜜および糖アルコール(D-マンニトール、エリスリトール等)等の糖類を適宜配合したもの等が挙げられる。中間被覆層には、この他にも下記する錠剤化を行うため必要により添加される賦形剤(例、隠蔽剤(酸化チタン等)、静電気防止剤(酸化チタン、タルク等)、結合剤(ポリエチレングリコール等)等)を適宜加えてもよい。
中間被覆層の被覆量は、有効成分含有核錠1重量部に対して、通常、約0.02重量部~約0.10重量部、好ましくは約0.02重量部~約0.05重量部である。被覆は常法によって行える。例えば、これらの中間被覆層成分を精製水等で希釈し(中間層コーティング液)、液状として散布して被覆するのが好ましい。その際、ヒドロキシプロピルセルロース等の結合剤を噴霧しながら行うのが好ましい。続いて、この中間被覆層を該腸溶性被覆基材でコーティングすることができる。
実施例、比較例および試験例で用いた4-[2-(4-メチルフェニルスルファニル)フェニル]ピペリジン臭化水素酸塩は、それぞれ国際公開第2003/029232号パンフレットの実施例に記載の方法等に準じて適宜製造して得られたものを用いた。また、メタクリル酸共重合体(分散液)としては、オイドラギット(登録商標)L30D-55(エボニックインダストリーズAG社製)を用いた。オイドラギットL30D-55は、メタクリル酸とアクリル酸エチルの共重合体の分散液(固形分濃度30%)で、ポリソルベート80及びラウリル硫酸ナトリウムを含有する。固形分の組成比は、メタクリル酸共重合体(97重量%):ポリソルベート80(2.3重量%):ラウリル硫酸ナトリウム(0.7重量%)である。

組成を表3に示す。腸溶性被覆基材3 988.5g(固形分濃度:15重量%)を調製した。なお、調製に当たっては、分散性の悪い酸化チタン、三二酸化鉄、黄色三二酸化鉄は強いシェアのかけられる分散機(10000rpm程度の回転速度)を、残りの成分は攪拌機(500rpm程度)を使用して別々に調製し、最終的にこれらを混合してコーティング液とした(以下の実施例において同様)。なおコーティング中は固形成分の凝集・沈降を避けるため、コーティング液を攪拌機(300-500rpm程度)で攪拌しながらスプレーした。

実施例1~3で得られた腸溶性錠剤の耐酸性および崩壊性を第15改正日本薬局方の崩壊試験法により調査を行った。耐酸試験液(0.1N塩酸またはpH4.5酢酸緩衝液)を用いて120分間試験を実施し、試験前後での錠剤重量変化からAcid Uptakeを測定した。その後、崩壊試験液(pH6.8りん酸緩衝液)に錠剤を移し、本試験液中での崩壊時間を測定した。なお、Acid Uptakeとは腸溶性被膜の耐酸性の評価法であり、この値が10%以下であれば、錠剤内部への水分透過は起こっておらず、結果、腸溶性被膜が十分な耐酸性を有すると判断するための1つの指標である。Acid Uptakeは次式により算出した。
Acid Uptake(%)=(試験後の錠剤重量-試験前の錠剤重量)/試験前の錠剤重量 ×100
実施例1~3で得られた腸溶性錠剤のAcid Uptakeおよび崩壊時間を表8および9に示した。
実施例1、4~8で得られた各腸溶性錠剤の耐酸性および崩壊性を第15改正日本薬局方の崩壊試験法により調べた。耐酸試験液(0.1N塩酸またはpH4.5酢酸緩衝液)を用いて120分間試験を実施し、試験前後での錠剤重量変化からAcid Uptakeを測定した。その後、崩壊試験液(pH6.8りん酸緩衝液)に錠剤を移し、本試験液中での崩壊時間を測定した。実施例1、4~8で得られた腸溶性錠剤のAcid Uptakeおよび崩壊時間を表10および11に示した。
実施例3、9~13で得られた各腸溶性錠剤の耐酸性および崩壊性を日局の崩壊試験法により調べた。耐酸試験液(0.1N塩酸またはpH4.5酢酸緩衝液)を用いて120分間試験を実施し、試験前後での錠剤重量変化からAcid Uptakeを測定した。その後、崩壊試験液(pH6.8りん酸緩衝液)に錠剤を移し、本試験液中での崩壊時間を測定した。実施例3、9~13で得られた腸溶性錠剤のAcid Uptakeおよび崩壊時間を表12および13に示した。
