Description
−結晶の破壊及び担体内部での非晶質相及び/又はナノ結晶構造の形成による薬剤の熱力学的活性化(非特許文献1;非特許文献2);
−薬剤それ自身の溶解速度の増加に結果として寄与する、活性成分を含んでいる担体粒子の寸法の減少、を可能にする。
Nakaiほか、Chem.Pharm.Bull.25,3340,1977年 Kawanoほか、J.Pharm.Dyn.5,S4,1982 DM28L 食品級振動型製粉機 Sweco社 取扱説明書 欧州薬局方、第3版、1997年、141頁 Nogamiほか、Chem.Pharm.Bull.14,329,1966年
−振動型製粉機が平面又は凸面の底面を持ち、互いに独立な0.4cmと3cmの間の直径と高さ、0.5と2の間の寸法比(rd)、及び0と0.5の間の曲率比(rc)を有している円筒形状の粉砕手段を含み、
−粉砕手段の間に構成される空間容積(間隙容積Vi)の35%と100%の間の薬剤−担体混合物の容積が使用される、
という点で特徴付けられている。
−製粉機が予めセットされた数の前述の粉砕手段で満たされる;
−製粉機中に存在する粉砕手段の間に構成される間隙容積(Vi)が決定される;
−製粉機はViの35と100%の間の容積の薬剤と担体の混合物で満たされる;
−製粉機は共粉砕を行うように操作される;
−活性化された薬剤−担体混合物が製粉機から再生される。
材料と方法
粉末(薬剤と担体)の混合物の密度は欧州薬局方、第3版に記載されたテストに従って決定された(軽く叩いた密度)。密度は前述の計器により2000叩きを行った後に測定された。
溶媒: 緩衝水溶液、pH=1.2
容積: 500mL
温度: 37℃
タービンの速度: 250rpm
タービンの位置: 底から2.5cm
試料の量: 媒質中の薬剤の溶解度の10倍に等価。
間隙容積の(Vi)の決定法
決められた量の粉砕手段が振動型製粉機の中に注がれた。間隙容積(Vi)は粉砕手段の床の表面に達するまでの量の水を注ぐことによって決定された。使用された種々の製粉機についての実験値が表1に与えられる。
実施例1Bの条件に従って粉砕手段で満たされたSwecoDM28製粉機に、様々な量のニメスリドとβ−シクロデキストリン(β−CDX)が表2で明らかなものに従って重量比1:3で注入された。
物理的混合物ニメスリド/β−CDX1:3w/wの密度は0.50g/mLであった。
ニメスリド生の素材の溶解度は10μg/mLであった。
実施例1Cの条件に従って粉砕手段で満たされたウイリャム−ブールトン社の3DM製粉機に、様々な量のイブプロフェンと澱粉グリコール酸ナトリウム(SSG)が表3で明らかなものに従って重量比1:1で注入された。
物理的混合物イブプロフェン/SSG1:1w/wの密度は0.64g/mLであった。
イブプロフェン生の素材の溶解度は73μg/mLであった。
=薬剤+担体混合物による間隙容積(Vi)の充填%。
(**)n.p.=非生産:バッチの生産が温度の上昇及びそれに従ってイブプロフェンの融点に起因する製品の通過が原因で不可能であった。
ニメスリド:β−シクロデキストリン(実施例2B−2D)1:44−1:15
イブプロフェン:SSG(実施例3B−3D)1:35−1:12。
2b:III=2mm;IV=60゜;V=6cm;
2c:VI=16cm;VII=1.3cm;VIII=0.3cm
