Abstract
Description
特段の記載がない限り、本明細書に用いられる全ての技術用語、表記、および他の科学用語は、本開示が属する技術分野の通常の知識を有する者によって一般的に理解される意味を有することが意図される。いくつかの場合において、明確性および/または手早い参照のために、一般的に理解される意味を有する用語を本明細書中で定義する。よって、本明細書中にそのような定義が含まれることは、当該技術において一般的に理解されているものと実質的に相違するものを表すと解釈されるべきではない。
NaOH(0.5M)またはリン酸塩を用いて5.0〜5.7のpHに緩衝されたカルグルミン酸溶液を用いて、予備溶解性試験を実施した。溶液が安定ではなかったこと、およびカルグルミン酸の水溶液中には存在しなかった未知の分解生成物(HPLC−質量分析法によって検出される159[M+H]-の分子イオンを有する)を与えたために、試験は成功しなかった。
・ 緩衝剤としてトロメタモールを含有する希釈剤で戻される(還元される)、カルグルミン酸および増量剤を含有する凍結乾燥配合物。
・ カルグルミン酸、トロメタモールおよび増量剤を含有する凍結乾燥配合物。
水中に2.5gのカルグルミン酸を溶解させて、100mlの溶液を調製した。白色の懸濁物が得られた。透明な溶液が得られることなしに、懸濁物を30分間にわたって攪拌した。溶液を約45℃に加熱した。完全な溶液は、pH=1.9で得られた。
水中に5gのトロメタモールを溶解させ、次いで2.5gのカルグルミン酸を添加することにより、100mlの溶液を調製した。室温において、pH=8.2を有する透明な溶液が直ちに得られた。
増量剤を選択するために、第1の凍結乾燥試験を実施した。増量剤としてマンニトールおよびラクトースを含む実験室スケールのバッチ(2000ml)のプラシーボ溶液を調製した。それぞれの配合物について、20mlのバイアルを調製し、凍結乾燥させた。配合物の定性的および定量的組成を、第2表にて報告する。
溶液調製の終点におけるpHおよび浸透圧重量モル濃度を測定するために、カルグルミン酸(API)およびトロメタモール(TRIS)のモル比ならびに増量剤濃度の異なる配合物を調製した。配合物の定性的および定量的組成を、第3表にて報告する。
開発作業の終了後、ICH条件下の安定性研究を実施して、選択した配合物Aの長期(商業的)安定性に関するデータを収集した。2〜8℃で保管された、500mgのカルグルミン酸を含む凍結乾燥された配合物Aのバイアルを用いて12ヶ月まで得た結果を第6表にまとめる。
