中間層51は、ポリエチレン樹脂と吸収剤の混合物で構成され、混合物全体に占める吸収剤の割合が10~30質量%であり、樹脂としてのポリエチレンの割合が70~90質量%であることが好ましい。上記の質量割合であれば、内スキン層に用いる樹脂材料の組み合わせとそれらの混合比率に応じて十分な吸収特性を好適に発揮することができる。吸収剤は、水または水蒸気、気体、においなどの吸収する対象によって、シリカゲル、ゼオライト、酸化カルシウム、硫酸マグネシウム等を適宜選択できるが、本実施形態ではにおいの吸収能力に優れるゼオライトが好ましい。

内スキン層53について、各実験サンプルNo.1~14に示す樹脂の混合割合(No.1,6,10,14については単独)で実際に吸収フィルム50をインフレーション成形する。そこから得られた吸収フィルム50を層構成例と同様に積層させた積層体を用いて実際にPTP40を成形し、それぞれ以下の(A),(B),(C)3つの観点から評価を行った。
PTP40の成形時に、内スキン層53の目視検査を行い、プレヒート板(加熱板)への融着について合否を評価した。成形過程での目視は、例えばシート状の積層体がプレヒート板を通過した後に行う。合否の評価は「○」及び「×」とし、合格の「○」にはプレヒート板への融着が発生していない場合に該当することとした。また、不合格の「×」にはプレヒート板への融着が発生した場合に該当することとした。
各実験サンプルのジアセチルの吸収能力の比較試験は、サンプルのジアセチルガス吸収量について吸収前後のサンプル(試料)の質量を電子天秤で測定し、その質量差から求める方法を用いた。以下に手順を示す。
(1)試料を5cm×10cmに切り出し、(2)試料の吸収層を内側にして半分に折り曲げる。(3)試料の質量を測定し、記録する。(4)秤量瓶に塩化ナトリウムによる調湿塩(75%RH)を作成し、デシケータの底部に入れる。(5)秤量瓶にジアセチルを5ml入れ、デシケータの底部に入れる。(6)試料をデシケータ内に入れ、デシケータの蓋をする(シリコンで気密性を確保する)。(7)デシケータを40℃恒温槽に入れる。(8)2時間経過後、デシケータを恒温槽から取出し、さらに試料を取り出し、5分間室温下に放置する。(9)試料の質量を測定し、記録する。(10)先の(6)に戻り、同様に実施する。
実薬に適用するPTP包装体では、においの吸収能力の確保とその維持が求められる。そこで、PTPに実薬(オルメサルタンメドキソミル40mg錠)を充填したPTP包装体を作成し、評価者10人による、においの官能試験を実施した。試験方法は以下の通りである。
(1)保管及び使用時の過酷条件を想定し、PTP包装体を40℃の恒温槽で75%RHの環境に置く。アルミピロー外包装や乾燥剤は用いない。
(2)5日後、1週間後、2週間後の各保存経過時点で恒温槽からPTP包装体を取り出し、室温にて、においの官能試験を実施する。
(3)PTP包装体を鼻先に近づけ、錠剤取出し時のにおいを評価する。
におい官能試験の評価基準は以下の通りである。
におい(特異臭)の強さを下記の5段階に分類する。
1)無臭、2)ほとんどにおわない(又は、極僅かににおう)、3)僅かににおう、4)におう、5)強くにおう
先ず実験サンプルNo.1~6のグループについて評価する。実験サンプルNo.1~6で内スキン層53に使用した樹脂の銘柄、及び内スキン層53の樹脂中に占める銘柄別の混合比率(質量%)を図4に示す。
実験サンプルNo.1のように、内スキン層53をLLDPE(1)単独で構成すると、(A)「耐プレヒート性」の評価は「×」となる。これは、樹脂材料としての融点が126°Cであり、予熱温度(130°C)より低いことが大きく関係しているためであると評価できる。なお、本実施形態では内スキン層53をLLDPE又はLDPEとHDPEとの混合樹脂で構成するため、実験サンプルNo.1は本発明の実施例と対比される比較例としての位置付けである。
図5は、各実験サンプルNo.1~6(ここではNo.5を除く)を上記デシケータ内のジアセチル環境に総合して10時間曝露したときの吸収率(%)を示している。図5では、横軸に内スキン層53のHDPEに対するLLDPEの混合比率(質量%)をとり、縦軸はジアセチル吸収率(%)を示している。図5の横軸上で、混合比率100%の結果は実験サンプルNo.1に対応し、以下、75%、50%、25%、0%の結果はそれぞれ、実験サンプルNo.2,3,4,6に対応している。また図5の縦軸に示すジアセチル吸収率(質量%)は、各実験サンプルNo.1~6に吸収されたジアセチルの質量を、各実験サンプル中に含まれる吸収剤の質量で除した比率(%)を表している。
図6は、実薬によるにおい官能試験結果を示す一覧表である。ここでは特に、4つの実験サンプルNo.4,5,6,10の各構成による積層体と実薬(オルメサルタンメドキソミル40mg錠)を用いて作成したPTP包装体を検体としている。なお、実験サンプルNo.10(PP(1)単独の層構成)は、他の実験サンプルNo.4,5,6との比較のため参考までに評価した。
以上の耐プレヒート性の評価結果、ジアセチル吸収能力の比較試験結果及び実薬(オルメサルタンメドキソミル40mg錠)を用いたにおい官能試験結果から、総合的な評価結果を以下に示す。
実験サンプルNo.7~9は、内スキン層53をLLDPE(1)とPP(1)との混合樹脂で構成したグループであり、これらは全て比較例としての位置付けである。また実験サンプルNo.10は、内スキン層53をPP(1)単独の樹脂で構成したものであり、同じく比較例として位置付けられる。実験サンプルNo.7~10で内スキン層53に使用した樹脂の銘柄、及び内スキン層53の樹脂中に占める種類別の混合比率(質量%)は図4に示す通りである。
以上より、実験サンプルNo.3,4,5を層構成例についての実施例とする。実施例において、内スキン層53に使用する樹脂材料は、LLDPE(1)と予熱温度よりも材料としての融点が高いHDPEとを混合した混合樹脂とする。また、混合樹脂に占めるLLDPE(1)の割合は25~50質量%の範囲とし、HDPEの割合は残余の75~50質量%の範囲とする。より好ましくは、混合樹脂に占めるLLDPE(1)の割合は10~50質量%の範囲とし、HDPEの割合は残余の90~50質量%の範囲とする。
次に、本発明の医薬用途に言及する。一実施形態のPTP又はブリスターパック40は、オルメサルタンメドキソミル含有製剤のブリスター包装に好適する。特に一実施形態のPTP又はブリスターパック40で製剤を包装することにより、オルメサルタンメドキソミル含有製剤のにおい発生の低減方法を実現することができ、そのために一実施形態のPTP又はブリスターパック40を使用することが好ましい。

(2)また、PTP又はブリスターパック40で包装された製剤20としてのオルメサルタンメドキソミル含有製剤は、蓋材30により封止された状態で、図1に示されるブリスター包装体10となる。
