Abstract
Description
従って、このような腸溶製剤の製造時における腸溶層の破損が抑制された腸溶性顆粒及び安定な腸溶製剤の開発が望まれている。
また本発明は、D-マンニトール及びポリエチレングリコールを含む腸溶性顆粒被覆用組成物を提供するものである。
また本発明は、D-マンニトール及びポリエチレングリコールを含む被覆用組成物で被覆された腸溶性顆粒を提供するものである。
また本発明は、D-マンニトール及びポリエチレングリコールを含む被覆用組成物で被覆された腸溶性顆粒を含有する腸溶性製剤を提供するものである。
本発明で用いられるD-マンニトールは、一般公知の市販のD-マンニトールを用いることができる。
本発明の固形製剤が錠剤、口腔内崩壊錠における成形は、例えばロータリー式打錠機等を用いて打錠することにより行うことができる。
乾燥は、例えば真空乾燥、流動層乾燥など製剤一般の乾燥に用いられる何れの方法によってもよい。
(工程1:レイヤリング・分級工程)
結晶セルロースを転動流動層造粒機に入れ,薬物の懸濁液(精製水,薬物、ヒプロメロースおよびポリソルベート80)をスプレーしレイヤリングを行う。続いて乾燥を行った後、篩に通して分級を行う。
(工程2:中間層コーティング・分級工程)
第1工程で製造した分級品を転動流動層造粒機に入れ、中間層コーティング液(精製水、ヒドロキシプロピルセルロース、タルク、ステアリン酸マグネシウム)をスプレーし、中間層コーティングを行う。続いて乾燥を行った後、篩に通して分級を行う
(工程3:溶出制御層・分級工程)
第2工程で製造した分級品を転動流動層造粒機に入れ、コーティング液(精製水、アンモニオアルキルメタクリレートコポリマー、クエン酸トリエチル、ポリソルベート80およびモノステアリン酸グリセリン)をスプレーし、コーティングを行う。続いて乾燥を行った後、篩に通して分級を行う。
(工程4:腸溶性コーティング・分級工程)
第3工程で製造した分級品を転動流動層造粒機に入れ、腸溶性コーティング液(精製水、メタクリル酸コポリマーLD、ポリエチレングリコール、ポリソルベート80およびモノステアリン酸グリセリン)をスプレーし、腸溶性コーティングを行う。続いて乾燥を行った後、篩に通して分級を行う。
(工程5:破損防止層コーティング・分級工程)
第4工程で製造した分級品を転動流動層造粒機に入れ、破損防止層コーティング液(精製水、ポリエチレングリコールおよびD-マンニトール)をスプレーし、破損防止層コーティングを行う。続いて乾燥を行った後、篩に通して分級を行う。
(工程6:)
第5工程で製造した分級品をV型混合機に入れ、そこにD-マンニトール、結晶セルロース、クロスポビドン、ケイ酸アルミン酸マグネシウムおよびアスパルテームを入れ混合する。その後、ステアリン酸マグネシウムを入れ混合する。
(工程7:打錠工程)
第6工程で製造した混合顆粒をロータリー打錠機を用いて打錠する。
球形結晶セルロースを転動流動層造粒機(フロイント産業社製、SFC-MINI)に入れ、エソメプラゾールマグネシウム水和物、ヒプロメロース、低置換度ヒドロキシプロピルセルロースおよびポリソルベート80を水に溶解・分散させた液を噴霧しながらコーティングした。得られた薬物層被覆粒子を乾燥後、ヒプロメロース、タルクおよびD-マンニトールを水に溶解・分散させた液を噴霧しながらコーティングした。得られた中間層被覆粒子を乾燥後、アンモニオアルキルメタクリレートコポリマー分散液(固形分30%)、クエン酸トリエチル、モノステアリン酸グリセリンおよびポリソルベート80を水に溶解・分散させた液を噴霧しながらコーティングした。得られた溶出制御層被覆粒子を乾燥後、メタクリル酸コポリマーLD分散液(固形分30%)、マクロゴール6000、モノステアリン酸グリセリン、ポリソルベート80および三二酸化鉄を水に溶解・分散させた液を噴霧しながらコーティングした。得られた腸溶層被覆粒子を乾燥、分級後、マクロゴール6000およびD-マンニトールを水に溶解させた液を噴霧しながらコーティングした。得られた破損防止層被覆粒子を乾燥、分級し、平均粒子径300μm、腸溶層破損防止層の膜厚が30μmの被覆微粒子を得た。
破損防止層であるマクロゴール6000およびD-マンニトールをコーティングしない代わりに、D-マンニトール・トウモロコシデンプン造粒品を増量した以外は実施例と同様の操作で錠剤を得た。
実施例、比較例により得られた錠剤について、錠剤硬度および第一液による溶出性を確認した。
その結果を表3に示す。
