Abstract
Description
本願は、米国仮特許法第119条の下、2008年12月5日に出願された米国仮特許出願61/120,081号への優先権を主張し、この米国仮特許出願の全体の内容は本明細書中に参考として援用される。
本発明は、懸濁剤として、比較的高分子量のポリエチレングリコール、ポリエチレンオキシドもしくは両方を含む薬学的懸濁物に関する。より具体的には、本発明は、懸濁剤として比較的高分子量のポリエチレングリコール、ポリエチレンオキシドもしくは両方を含み、治療剤および/または抗菌剤(例えば、ポリマー状四級アンモニウム化合物)を含む、眼用、耳用もしくは鼻用の薬学的懸濁物(例えば、複数用量の水性眼用懸濁物)に関する。
長年にわたって、製薬業界は、薬学的懸濁物の調製において有用な懸濁剤を開発し、発見し続けてきた。このような懸濁物は、治療剤の送達などのために効果的である。これら懸濁物は、広く種々の適用(例えば、非経口(parentral)、局所的、経口的、直腸的などおよび本発明にとって特に重要なのは、眼用、耳用および鼻用)において使用され得る。このような懸濁物の例は、特許文献1;特許文献2;特許文献3;特許文献4;特許文献5;特許文献6および米国特許出願公開第20060257487号;同第20060257486号;同第20060122277号;同第20030139382号;同第20020037877号(これらは全て、全ての目的で本明細書に参考として援用される)に記載されている。
本発明は、薬学的懸濁物に関する。上記懸濁物は、少なくとも2000、より好ましくは、少なくとも5,000、さらにより好ましくは、少なくとも10,000およびなおより好ましくは、少なくとも20,000の分子量を有する高分子量ポリエチレングリコール、ポリエチレンオキシドまたは両方を含む。上記懸濁物は、代表的には、水性であるが、別段述べられなければ要求はされない。
本発明は、薬学的懸濁物のために、懸濁剤として、比較的高分子量のポリエチレングリコール、ポリエチレンオキシドもしくは両方を提供し、使用することに関する。上記薬学的懸濁物は、代表的には、治療剤、抗菌剤もしくは両方を含む。上記懸濁剤は、代表的には、水性懸濁物を形成するために使用される。本発明の懸濁物は、非経口用、局所用、経口用もしくは直腸用懸濁物として適切であり得ることが予期される。さらにもしくは代わりに、上記懸濁物は、眼もしくは鼻への適用のために、耳用および/もしくは鼻用懸濁物として適切であることが見いだされた。しかし、上記懸濁物は、眼用懸濁物として特に適切であり、単一もしくは複数の用量の、眼への局所的もしくは他の適用に極めて有用である。
式I: H(OCH2CH2)nOH ここでnは、3より大きい。
H−(OCH2CH2)n−OH
ここでnは、オキシエチレン基の平均数を表す。上記懸濁物で利用されるPEOの分子量は、100,000〜8,000,000の範囲に及び得る。
保存剤効力試験(「PET」)基準
(微生物接種物の対数オーダーでの経時的な低下)
表Dおよび表Eは、RTKiと、異なるポリマーおよび界面活性剤の組成物を提供する。表D中の例を、10% RTKiスラリーと、1% ポリソルベート80を使用して調製し、これを、ボールミルにかけて、平均体積粒径を、約3ミクロンに低下させた。表E中の例を、10% AL−39324スラリーと1% チロキサポールを使用して調製し、これを、ボールミルにかけて、平均体積粒径を約3ミクロンに低下させた。上記ポリマー溶液を、使用前にオートクレーブにかけるかもしくは滅菌濾過のいずれかを行って、これら組成物を作製した。これら組成物の粘性、静置した際の沈降体積%、および再分散性結果を、表Fおよび表Gに提供する。上記粘性を、剪断速度約46秒−1を生じる12rpmにおいて、CP−42スピンドル付きのBrookfield LV粘度計を使用して測定した。再分散時間を、以前に提供された手順を使用して測定し、遠心分離を約16時間にわたって行った。
