Description
ポリスチロールスルホン酸ランタンが慢性腎臓の衰弱 (いわゆるCRF)高燐酸血症を治療できる作用があること証明するために、次の通り実験を行った。
1、ポリスチロールスルホン酸ナトリウムを100グラム取り、塩酸による酸性化処理によってポリスチロールスルホン酸を得てから、400ミリリットルの濃度が50%の硝酸ランタン溶液に浸漬して、温度を50℃にしたまま8時間放置して、pH値が中性になるまで水で洗浄し、置換していない余分なランタンイオンをきれいに洗浄して、ポリスチロールスルホン酸ランタンを取り出し、乾燥させ、粉状に粉砕する。得られたポリスチロールスルホン酸ランタン中のランタンの重量は16%である。ポリスチロールスルホン酸ランタンの粉状物を使い、補助薬剤と一緒に規定の使用量及び規定の処方によって薬剤を製造する。
