Description
(1)アナグリプチン又はその塩を含有し、その水溶液又は水分散液のpH値が10以下である医薬組成物。
(2)弱酸性〜弱塩基性製剤添加物を含有する、(1)記載の医薬組成物。
(3)アナグリプチン又はその塩の含有量が、医薬組成物全質量に対し1〜90質量%である、(1)又は(2)記載の医薬組成物。
(4)その水溶液又は水分散液のpH値が2〜10である(1)〜(3)のいずれか1項記載の医薬組成物。
(5)経口投与用固形製剤である、(1)〜(4)のいずれか1項記載の医薬組成物。
(6)前記経口投与用固形製剤が、錠剤、カプセル剤、顆粒剤、細粒剤、又は散剤である、(5)記載の医薬組成物。
[試験例]アナグリプチンの各種pH条件下での安定性の検討
アナグリプチン625mgを、25℃の条件下でpH2、3、7、10、11又は12に調整したBritton−Robinson緩衝液100mlに溶解し、25℃にて1日間保存し、試験開始時及び1日保存後のアナグリプチンを定量することにより、各種pH条件下での安定性を評価した。
なお、アナグリプチンの定量値(%)は、HPLCを用いて、濃度既知の標準溶液とピーク面積を比較することにより算出した。
以上の試験結果から、アナグリプチン又はその塩を含有する医薬組成物の水溶液又は水分散液のpHを10以下とすることにより、アナグリプチン又はその塩の安定性に優れる医薬組成物が得られることが明らかとなった。
以下の方法により、1錠中にアナグリプチンを100mg含有する錠剤を製造した。
すなわち、アナグリプチン100質量部を、ヒドロキシプロピルセルロース水溶液(ヒドロキシプロピルセルロースとして1.5質量部)を用いて、流動層造粒した。得られた粒状物を乾燥後整粒し、整粒物にクロスポビドン15質量部及び結晶セルロース(旭化成ケミカルズ(株)製:セオラスKG−802)32質量部を添加し、混合した。次いで、ステアリン酸マグネシウム1.5質量部を添加し、混合して、打錠用顆粒を得た。得られた打錠用顆粒を1錠当たり150mgとなるように打錠して、錠剤を得た。
また、得られた錠剤をプラスチックシャーレに入れ、温度60℃、相対湿度75%にて、21日間の安定性試験を実施した。アナグリプチンの分解生成物量は1.58%であり、アナグリプチンの安定性は良好であった。
