Abstract
Description
本出願は、2012年9月18日に出願された米国仮特許出願第61/702,576号に対する優先権を主張するものであり、参照によりその全体が本明細書に組み込まれる。
留置膀胱及び頸静脈カニューレを装着したラットに、塩化オキシブチニン、トルテロジンタータラート、又は塩化トロスピウムを膀胱内灌流する研究を実施した。手術後、ラットは完全に可動性があった。
酢酸と共に上昇する濃度の様々な投薬量の塩化オキシブチニン、トルテロジンタータラート、又は塩化トロスピウムで、頸動脈及び膀胱カテーテルを挿入したラットを膀胱内灌流した。対照期間及び治療期間の間、収縮間隔及び膀胱内圧を測定した。
生体外実験を行い、長期間にわたる塩化トロスピウムのゼロ次放出を示した。各デバイスに平均約77mgの塩化トロスピウムを装填した状態で、シリコーンチューブのデバイス筺体を使用した。シリコーンチューブ内径は1.5mmであった。グループ1(N=3)については、シリコーンチューブ壁は0.2mm厚であり、グループ2(N=3)については、シリコーンチューブ壁は0.8mmであった。各デバイスが、チューブの1つの端部に位置する放出用オリフィスを有する状態で、装填されたシリコーンチューブの端部を封鎖した。全デバイスのオリフィスの直径は、0.28mmであった。塩化トロスピウムは錠剤の形態であり、該錠剤の長さはおよそ3.8cmであり、該錠剤は、90%の塩化トロスピウム(TrosCl)、5%のPVP、及び5%のPEG8kから成る製剤を有した。
