レンボレキサントの原薬の未粉砕品を用いて、160UPZ(プレートビータ、ピンミル)の回転数を変化させることにより、異なる粒度を持つ複数のレンボレキサントの原薬を調製した。
レンボレキサントの原薬の未粉砕原薬1kgをあらかじめ容器に量りとり、ストップウォッチで時間を測りながら粉砕機(160UPZプレートビータ、目開き1mmスクリーン)へ投入した。投入はスコップを用いた手投入で行った。回転数は4000、5600、8000、9500rpm、Feed rate10kg/hの条件で実施した(ロットS1、S2、S3、S4、S6)。ただし、ロットS6については、回転数5600rpm、Feed rate60kg/hの条件で1回粉砕した後(ロットS5)、160UPZピンミル5600rpmで粉砕した後、続けて10000rpmで続けて粉砕し調製した。各粉砕条件及び得られた粉砕後の90%累積径(D90)を表2にまとめた。
90%累積径(D90)の測定は、粒度分布計(マイクロトラックMT3300EXII)により行った。レンボレキサントの原薬約30mgを分散溶媒0.1%ポリソルベート20水溶液50mLに分散させたものを試料懸濁液とした。試料懸濁液を粒度分布計に投入し、適切な量の分散溶媒を加えた。試料懸濁液の粒子径分布を測定し、試料の粒子径の値を累積径分布として記録した。
粒度分布計の測定条件は、以下のとおりである。
流速:50%
測定回数:3回
測定時間:30秒
形状:非球形
透過性:透過
粒子屈折率:1.81
溶媒屈折率:1.33
実施例1で得られた各ロット(S1、S2、S3、S4、S6)を使用して、レンボレキサント2.5mg及び10mg錠剤を製造した。
製造した錠剤の構成成分及び組成を表3に示した。
(1)装置及び材料
溶出試験に使用した装置及び材料は、表4にリストした。
実施した溶出試験条件は、表5に示した。
各試験は実施例2に記載の方法で製造した6又は12個の錠剤で実施した。
溶出試験は、第十六改正日本薬局方にリストされたパドル装置に従って実施した。錠剤は、900mLの0.1mol/Lの塩酸、溶出試験第1液(pH1.2)、薄めたMcIlvaine緩衝液、溶出試験第2液(pH6.8)又は水を試験液として用いて、50rpm又は100rpmのパドル回転速度によって試験した。一定分量の試験液を定められた時点でフィルターを通して取り出した。標準溶液は、サンプル溶液の通常濃度に対応するレンボレキサント濃度を有するように調製した。放出されたレンボレキサントの量はHPLC又は紫外可視吸光度測定法によって決定した。HPLC条件及び紫外可視吸光度測定法の条件は、以下に示した。
<HPLC条件>
検出器:紫外吸光光度計(測定波長:283nm)
カラム:内径4.6mm、長さ7.5cm(YMC-TriartC18(YMC))
充填剤:3μmの液体クロマトグラフ用オクタデシルシリル化シリカゲル
カラム温度:40℃
移動相:水/アセトニトリル/70%過塩素酸(550:450:1、v/v/v)
流量:1.2mL/min
注入量:50μL
サンプルラック温度:25℃
分析時間:5分間
<紫外可視吸光度測定法の条件(0.1mol/L塩酸についてのみ本法で測定>
測定波長:233nm及び400nm
対照:試験液
試験は、6又は12個の錠剤で実施され、それらの平均値を示した。0.1mol/Lの塩酸を試験液として用いた場合の、レンボレキサント2.5mg及び10mg錠剤の溶出試験の結果を表6及び表7並びに図1に示した。すべての錠剤は、レンボレキサントの原薬の粒子径及び含有量にかかわらず0.1mol/Lの塩酸において、15分で完全に溶出した。
よって、レンボレキサントの原薬の粒子径(D90)を64μm以下にすることにより、良好な溶出プロファイルを示し、均質な医薬組成物を提供することができることが示唆された。
また、実施例3の溶出試験は、米国薬局方(USP42)の<711>Dissolutionの項に記載されるように、日本薬局方、米国薬局方及び欧州薬局方において調和されている試験方法である。かかる試験方法に基づき、2.5mg錠剤及び10mg錠剤で良好な溶出プロファイルを示すことを確認している。2.5mg錠剤と10mg錠剤は,1錠中における原薬量の差分を乳糖水和物で置き換えた処方であるため、ブラケッティング法により2.5mg~10mgの錠剤、例えば、5mg錠剤においても同様に良好の溶出プロファイルを示すことが期待される。
製造した錠剤の構成成分及び組成を表18に示した。
(1)装置及び材料
溶出試験に使用した装置及び材料は、表19にリストした。
実施した溶出試験条件は、表20に示した。
各試験は実施例4に記載の方法で製造した6個の錠剤で実施した。
溶出試験は、第十六改正日本薬局方にリストされたパドル装置に従って実施した。錠剤は、900mLの0.1mol/Lの塩酸を試験液として用いて、50rpmのパドル回転速度によって試験した。一定分量の試験液を定められた時点でフィルターを通して取り出した。標準溶液は、サンプル溶液の通常濃度に対応するレンボレキサント濃度を有するように調製した。放出されたレンボレキサントの量は紫外可視吸光度測定法によって決定した。紫外可視吸光度測定法の条件は、以下に示した。
<紫外可視吸光度測定法の条件>
測定波長:233nm及び400nm
対照:試験液
試験は、6個の錠剤で実施され、それらの平均値を示した。0.1mol/Lの塩酸を試験液として用いた場合の異なる打錠圧で製造したレンボレキサントの2.5mg、10mg及び5mg錠剤について溶出試験の結果を表21~表23並びに図8に示した。
