Abstract
Description
本願は2008年11月4日に出願された米国出願第12/264,709号の継続出願に基づくものであり、その内容のすべてを本明細書に参照して援用し、また本願の一部となる。
本例は、70%を超える薬物負荷を有するナトリウムオキシベートの圧縮錠剤の3つの製剤を提供する。ローラー圧縮を造粒用の製造方法として用いて錠剤を調製した。錠剤の組成を以下の表1に要約する:
ナトリウムオキシベート錠剤の生体利用効率および生物学的同等性
製剤A(6錠剤として与えられた4.5gの製剤A:治療A)、製剤B(6錠剤として与えられた4.5gの製剤B:治療B)およびXyrem(4.5gのナトリウムオキシベート経口溶液:治療C)の第1段階、3方向、非盲検、ランダム化された単一投与量の交差研究である。1〜21日間のスクリーニング期間の後、各被検体の研究期間は約7日間で、期間1が1〜2日目、期間2が3〜4日目、期間3が5〜6日目である。2日目の洗浄期間(最初の日の午前中投薬し、その後1日の洗浄)は、治療A、BおよびCを区別した。
ナトリウムオキシベート錠剤の溶解プロファイル
図1は、本発明の一実施形態の溶解プロファイルを示す。実施例1に製剤Cとして記載した投薬形態は、即時放出プロファイを有する。即時放出錠剤は、ナトリウムオキシベートを1時間未満内に放出する。この放出プロファイルは、実施例1に記載の即時放出組成物の2つの溶解曲線(製剤AおよびB−図2参照)の間の中間で、Xyrem(登録商標)溶液と生物学的に同等であることを示し(実施例2参照)、従って該組成物がまたXyrem(登録商標)溶液と生物学的に同等であることを立証した。
