Abstract
Description
本出願は、米国特許法第119条(e)項に基づいて、2002年4月8日付けで提出された米国出願第60/370,213号および2002年4月8日付けで提出された米国出願第60/370,245号に対する利益を主張するものであり、各出願の開示はその全文が参照として本明細書に組み入れられる。
本発明は、プロポフォールの水溶性プロドラッグを含む組成物、ならびに長期の鎮静を誘発および維持するための方法を含むそのプロドラッグの投与方法に関する。
プロポフォール(2,6-ジイソプロピルフェノール)は、ヒトおよび動物における麻酔または鎮静の導入および維持において静脈内投与用の催眠剤または鎮静剤として広く用いられる低分子フェノール誘導体である。麻酔薬としてのその有用な特性には、静脈内投与による投与、麻酔の速やかなオンセットおよびオフセット、速やかなクリアランスがあり、副作用プロフィールの面でもバルビツール酸塩などのその他の注射可能麻酔薬より好ましい。
本発明はいずれの理論にも縛られるものではないが、このプロドラッグは内皮細胞表面のアルカリホスファターゼによる加水分解を受けてプロポフォールを放出すると考えられる。
一つの局面において、本発明は、それを必要とする対象において全身麻酔状態を導入または維持する方法を提供する。この方法は式Iの化合物:
または薬学的に許容されるその塩を少なくとも1回ボーラス注射する工程を含み、ここで、それぞれのZは水素、アルカリ金属イオンおよびアミンからなる群より独自に選択される。本化合物は、体重1キログラム当たり10mgを超える量から約50mgまでの量で投与される。
プロポフォールプロドラッグの注入から得られる血漿中プロポフォールは被験者におけるEEG活性の抑制および催眠効果の惹起の点でプロポフォール自体の注入から得られる血漿中プロポフォールよりも極めて強力であったことが見出されている(図3)。注入可能物質としてのプロドラッグの優れた予想外の特性は、被験者において意識鎮静状態を速やかに導入および維持する能力によってさらに示され、この能力は注入速度を変化させることによって素早く調節することができる。
または薬学的に許容されるその塩であり、ここで、それぞれのZは水素、アルカリ金属イオンおよびアミンからなる群より独自に選択される。好ましくは、各々のZはアルカリ金属イオン、特にナトリウムイオンである。
以下の実施例は本発明のより良い理解を促すために提供される。本実施例は、限定的ではなく例示的なものとして見なされるべきである。O-ホスホノオキシメチルプロポフォールの2%水溶液は、以下の表1に示される組成物を用いて調製された。
この実施例では、健常男性志願者の電気的脳活動および意識に対するプロポフォールおよびO-ホスホノオキシメチルプロポフォール二ナトリウム塩(AQUAVAN(商標))の目標制御注入(TCI)の影響を比較する。20mg/mLのAQUAVAN(商標)および0.4重量%NaClを用いて、20mL容バイアルに無菌溶液を調製した。溶液のpHは、必要に応じてHClまたはNaOHを用いて8.6±0.4に調整した。
この実施例は、健常志願者の覚醒レベルおよび鎮静レベルに対するAQUAVAN(商標)の目標制御注入(TCI)の影響を示す。AQUAVAN(商標)の無菌溶液は、上記の実施例1において記載した通りに調製した。
この実施例では、本発明記載のプロドラッグであるO-ホスホノオキシメチルプロポフォール二ナトリウム塩(AQUAVAN(商標))を単回ボーラス投与として投与した際のプロポフォールの薬物動力学を、そのように投与した際のプロポフォールの薬物動力学と比較する。無菌溶液である「試験調製物」は、20mg/mlのAQUAVAN(商標)および0.4重量%NaClを用いて20ml容バイアルに調製した。溶液のpHは、必要に応じてHClまたはNaOHを用いて8.6±0.4に調整した。
5mg/kg(コホート1)および10mg/kg(コホート2)のボーラス投与では、意識消失(LOC)は起こらなかった。
