アジスロマイシン非二水和物の水および矯味矯臭化経口用懸濁液剤中での安定性
アジスロマイシン非二水和物の様々な形態の、水および矯味矯臭化経口用懸濁液剤中での安定性を、調べた。特に、アジスロマイシン非二水和物の形態G、M、N、FおよびJは個別にPOS製剤IIで用いた。これらのPOS製剤は水18mlと混合して再構成した。この懸濁液剤は次に5℃または30℃のいずれかで1、5および10日間保存した。バルクのアジスロマイシンの形態G、M、N、FおよびJもまた水18mlにより再構成しそして同じ条件下で保存した。
保存期間の終了時、この懸濁液剤を濾過しそして懸濁した固形物を前述のように回収した。次にこれらの固形物を、回収したアジスロマイシン試料の、質量%(% wt)で記述した、アジスロマイシン二水和物(形態A)の存在量を定量するために、SS−NMRにより分析した。
形態転換への個々の矯味矯臭剤およびショ糖の効果
提案された賦形剤を調べるために、アジスロマイシンの活性用量を、pHを8.16に調整した0.1Mリン酸緩衝系中に、可能性のある賦形剤の所望の量と共に、懸濁した。この緩衝系は、13.738gのNaH2PO4・H2Oを900mlの水に溶解し、水酸化ナトリウムでpHを8.16に調整し、そして水で溶液を1ルットルまで希釈して、作成した。一旦緩衝液で再構成した試料を、次に室温で所望の再構成された生成物の保存期間、保存した。アジスロマイシン生成物を次に濾過で分離し、そして得られた固形濾過物を、先に記載した、存在する二水和物の定量を可能にする、固体核磁気共鳴法で分析した。
懸濁液剤中での、アジスロマイシン形態Gからアジスロマイシン二水和物(形態A)への転換に対する、各種の個別の矯味矯臭剤成分およびショ糖の効果を、以下のように調べた。
アジスロマイシン形態転換を促進する矯味矯臭剤の成分の同定
実施例1において、アジスロマイシン非二水和物を、経口用懸濁液剤の投与剤形としての使用に適した、矯味矯臭化懸濁液中で再構成した場合、アジスロマイシン形態転換が生じることが示された。さらに、B&Cバナナに比較して、トルーシル人工バナナを含有する懸濁液剤中で得られた大きな転換速度は、トルーシル人工バナナがB&Cバナナよりも、より多くの量の転換促進物質またはより効率的な転換促進物質を含むことを証明していた。
による再構成によって証明されたように、有機成分の組み合わせはまた、個々の分離した成分の効果と比較して、さらに二水和物種の形成を促進するように相互作用するだろう。この理由から、そうした現象を観察する可能性を最小限にするために、注意深い矯味矯臭剤の選択を通してそうした成分の組合せを避けるだけではなく、最少量の有機成分を含む矯味矯臭剤を選択することが有利である。
シクロデキストリンの添加による安定化
アジスロマイシン非二水和物である形態G、MおよびFの再構成されたPOS製剤中での転換に対する、シクロデキストリンのような抱合剤の効果を調べた。
形態G、MおよびFのアジスロマイシンはPOS製剤IIへと製剤化された。各種のシクロデキストリンをPOS製剤IIへと加え、そして得られた試料を水の18mlで再構成した。次に
この懸濁液剤を室温で24時間保存した。この保存時間の終了時に、懸濁液剤を濾過しそして回収した固形物を秤量し、そしてSS−NMRでアジスロマイシン二水和物(形態A)の存在の定量のために分析した。コントロール試料は、シクロデキストリンなしで、アジスロマイシン非二水和物の形態G、MおよびFを有する製剤IIへと製剤化し、そして水で再構成し、保存し、濾過し、そして上記のシクロデキストリン試料と同様に分析した。シクロデキストリンを含まないコントロールは、各実験のシリーズで実施した。SS−NMRのデータを表10、11、12に示し、そして結果は、回収したアジスロマイシン試料の質量%で表している。
