Description
このようなメリットを考慮して、本発明者はピタバスタチン又はその塩を含有する崩壊性が良好な固形製剤を得るため、カルメロース又はその塩、クロスポビドン、結晶セルロースといった崩壊剤とピタバスタチン又はその塩とを混合したところ、経時的に多量のラクトン体が生成することが判明した。
従って、本発明は、ピタバスタチン又はその塩と、カルメロース及びその塩、クロスポビドン並びに結晶セルロースよりなる群から選ばれる1種以上とを含有する、ラクトン体生成の抑制された固形製剤、及び当該固形製剤を用いた医薬品を提供することを課題とする。
(A)ピタバスタチン又はその塩;
(B)カルメロース及びその塩、クロスポビドン並びに結晶セルロースよりなる群から選ばれる1種以上;
を含有し、かつ、水分含量が2.9質量%以下である固形製剤を、気密包装体に収容してなる医薬品を提供するものである。
(A)ピタバスタチン又はその塩;
(B)カルメロース及びその塩、クロスポビドン並びに結晶セルロースよりなる群から選ばれる1種以上;
を含有し、かつ、水分含量が2.9質量%以下である固形製剤を提供するものである。
また、本発明の医薬品は、本発明の固形製剤が気密保存可能な包装体にて包装され包装体内への水分の侵入が妨げられるため、長期間に渡って包装体内部の固形製剤の水分含量が安定的に保たれ、固形製剤中のピタバスタチン又はその塩由来のラクトン体生成が長期間に渡って抑制され、有用である。
本発明においては、ピタバスタチンカルシウム(化学名:(+)-monocalcium bis{(3R,5S,6E)-7-[2-cyclopropyl-4-(4-fluorophenyl)-3-quinolyl]-3,5-dihydroxy-6-heptenoate})が好ましい。
ピタバスタチン又はその塩は公知の化合物であり、例えば、特開平1-279866号公報、米国特許第5856336号明細書等に記載の方法により製造することができる。

なお、後掲の試験例3に記載の通り、本発明の固形製剤の水分含量を1.5質量%以上とした場合、ラクトン体とは別の分解物である5-ケト体の生成を抑制できる。5-ケト体は、特許文献5記載の通りピタバスタチン又はその塩を光に曝すことによって生じる光分解物であることが知られているが、水分との関係についてこれまでに報告はない。
従って、水分含量が1.5~2.9質量%(好適には1.5~2.1質量%、特に好適には1.5~1.9質量%)である本発明の固形製剤は、ラクトン体の生成が抑制され、また、5-ケト体の生成も抑制されるため、固形製剤中のピタバスタチンの安定性が特に良好であるという優れた効果を有する。
(A)ピタバスタチン又はその塩;
(B)カルメロース及びその塩、クロスポビドン並びに結晶セルロースよりなる群から選ばれる1種以上;

高い吸湿性を有する崩壊剤との共存下におけるピタバスタチン又はその塩由来のラクトン体生成を確認するため、以下の混合物1~4を調製してポリエチレン製の袋及びアルミ袋に入れ70℃で3日間保存し、混合物調製直後及び70℃、3日保存後の混合物中のラクトン体の生成率を評価した。ラクトン体の生成率は、各混合物につき、HPLC装置(WATERS製2695)を用いて、ピタバスタチン及びその分解物に由来する総ピーク面積に対する面積百分率として測定した。なお、参考のため、ピタバスタチンカルシウムのみ別途70℃、3日保存した場合のラクトン体の生成率も同様に評価した。
水分含量は、第十六改正日本薬局方の水分測定法(カールフィッシャー法)に準拠して、容量滴定法により測定した。結果を表1に示す。
ピタバスタチンカルシウム1質量部と、クロスポビドン(BASF社製:商品名 コリドンCL-SF)10質量部とを混合し、混合物1を調製した。
<混合物2>

<混合物4>
ピタバスタチンカルシウム1質量部と、カルメロースナトリウム(第一工業製薬社製:商品名 セロゲンP-815C)10質量部とを混合し、混合物4を調製した。
下記の方法により製造した口腔内崩壊型錠剤の水分含量を、真空乾燥にて表3に示す各水分含量に調整した(なお、水分含量の測定方法は下記の通り)。その後、水分含量の調整された各錠剤(100錠)を、予めポケット部分を成形した樹脂シート(住友ベークライト社製:商品名 スミライトVSS-1202-R)のポケット部分に入れ、次いでPTP用アルミ箔(大和化学工業社製:商品名 アルミ箔銀無地)で蓋をしてPTP包装し、得られたPTP包装体を更にアルミラミネート袋(生産日本社製:商品名 ラミジップALシリーズ)でアルミピロー包装した。こうして得られた包装体を40℃、75%相対湿度の条件下で2ヵ月間保存し、錠剤調製直後、1ヶ月保存後及び2ヶ月保存後の、錠剤中のラクトン体の生成率を評価した。ラクトン体の生成率は、各錠剤につき、HPLC装置(SHIMADZU製LC-20シリーズ)を用いて、ピタバスタチン及びその分解物に由来する総ピーク面積に対する面積百分率として測定した。
また、錠剤中の水分含量は、第十六改正日本薬局方の水分測定法(カールフィッシャー法)に準拠して、容量滴定法により測定した。

試験例2と同一の方法により、種々の水分含量の口腔内崩壊型錠剤をPTP包装、次いでアルミピロー包装して得られた包装体を40℃、75%相対湿度の条件下で2ヶ月間保存し、錠剤調製直後、1ヶ月保存後及び2ヶ月保存後の、錠剤中の5-ケト体の生成率を評価した。5-ケト体の生成率は、各錠剤につき、HPLC装置(SHIMADZU製LC-20シリーズ)を用いて、ピタバスタチン及びその分解物に由来する総ピーク面積に対する面積百分率として測定した。
