Description
コンタクトレンズケア液は非常に高い可能性で緩衝剤系を含むであろう。用語「緩衝剤」又は「緩衝剤系」とは、緩衝能力、すなわち、当初のpHを比較的に小さい変化で変化させ又は全く変化させずに酸又は塩基(アルカリ)を範囲内で中和させる能力を示す溶液中の緩衝性系を提供する化合物で、通常、少なくとも1つの他の化合物との組み合わせでの化合物を意味する。一般に、緩衝性成分は0.05%〜2.5%(w/v)又は0.1%〜1.5%(w/v)で存在する。
表6に示す例1〜5ならびに比較例1及び2のコンタクトレンズ組成物は下記のプロセスを用いて調製される(成分はppmと記載していないかぎり、wt%として示す)。合計バッチ質量の85〜90%に相当する体積の精製水をステンレススチール混合容器に添加する。下記のバッチの量の成分を示した順序で攪拌しながら水に添加する:塩化ナトリウム、エデト酸二ナトリウム、ホウ酸、ホウ酸ナトリウム及びポロキサミン1107。液を10分間以上の時間、混合(攪拌)し、各成分の完全な溶解を確保する。この液を70℃以上の温度に加熱し、そしてヒアルロン酸ナトリウムを添加する。温められた液をヒアルロン酸ナトリウムが完全に溶解したようになるまで少なくとも20分間攪拌する。得られた溶液のpHを室温にて測定し、もし必要ならば、pHを1NのNaOH又は1NのHCl(目標pH=7.5)に調節する。その液を、その後、121℃で少なくとも30分間加熱滅菌する。
製剤の活性を評価するために、サンプルを4オンスPET容器中に入れ、そして周囲温度、及び、高温に所定の時間貯蔵した。サンプルの独立殺生物効力を指定した間隔で試験し、消毒活性について、時間経過に伴う製剤の安定性を決定する。「消毒製品の独立手順」(Stand- Alone Procedure for Disinfecting Products)は、米国食品医薬局(FDA)、眼科デバイス課によって用意された、1997年5月1日付けの製品の消毒効力試験に基づいている。この性能要求は摩擦手順を含まない。
レジメン効力試験は有機体汚染液中の試験有機体1.0×107〜1.0×108CFU/mLの懸濁液0.01mLでコンタクトレンズの両面を最初に接種することを含む。接種材料を20〜25℃で5〜10分間、各レンズに吸着させる。吸着の時間の後に、レンズの各面を試験液で5秒間濯ぎ、その後、4時間、標準B&Lレンズケース中に保存された試験液中に含浸させる。生存している攻撃有機体を回収するために、所定の体積の確証された中和媒体をろ過装置に入れる。所与のレンズケースの全内容物(レンズ及び試験液)をろ過装置中の中和媒体に移す。適当な中和暴露時間後に、ろ過装置に真空を課し、液をろ過する。レンズを、試験有機体の回収に適する寒天培地床に無菌で移す。床中に使用されるのと同一の寒天(40〜50℃)を所与の量でレンズ上に注ぎ、キャストする。試験フィルターを、試験有機体を回収するのに適する寒天培地の表面に配置する。細菌回収プレートを30〜35℃で2〜4日間インキュベートし、イースト回収プレートを20〜25℃又は30〜35℃で3〜5日間インキュベートし、そしてカビ回収プレートを20〜25℃で3〜7日間インキュベートする。適切な接種材料、レンズの接種、ならびに、中和及び回収対照物を各試験で操作する。
レンズケースの各ウェルを、試験液又は対照液のいずれかで予備処理(1回、最低で4時間浸漬)した。各場合に、試験液で処理したウェルと、対照液を受けた相手方のウェルをランダムに決定した。予備処理されたレンズケースの中で、すべてのPureVision(登録商標)レンズを、試験液又は対照液のいずれかで予備処理(最低4時間)し、次いで、レンズケースウェルについて用いた同一のランダム化を行った。レンズ挿入前に、表層点状角膜染色をスリットランプで評価した。レンズ装着の約2時間後に、各被験者は戻ってきた。レンズを取り外し、表層点状角膜染色プロファイルをスリットランプを用いて再評価した。対照液はOpti-Free(登録商標)Replenishである。
多施設覆面実薬対照相互対比群2週間試験(multi-center, masked, active-controlled, bilateral, parallel-group, two-week study)を、被験者の半分に例5(試験液)のレンズケア液をランダムに受けさせ、そして半分にOpti-Free(登録商標)Replenish(対照液)を受けさせることで行った。試験の初めに、すべての被験者に彼らが常用しているレンズ(1/3がPureVision(登録商標)、1/3がAcuvue(登録商標)Oasys、1/3がNight & Day(登録商標)又はO2Optix(登録商標))及び試験レンズケア液又は対照レンズケア液のいずれかを分配した。被験者に液の使用及びレンズのケアを指示した。被験者に対して、試験の最初の1週間について、毎日の日記を付けさせ、それぞれの賛助者に完了した試験をメールすることを要求した。試験ではアジア系人361人の被験者(347人が試験を完了)が含まれ、表14に人口統計を示す。
各々の目について、0〜100スケールを用いて、被験者の主観的な症状/病気を等級化した。0は幾つかのレンズケア特性(たとえば、一日の終了時の快適さ、レンズの挿入時の激しい刺激/刺痛、炎症及び乾燥)を示し、そして100は最も好ましい等級である。2週間後の追跡訪問時に、例5の液は症状/病気について、対照液と統計的に有意な相違はなかった。試験液は、すべての日記レンズ性能等級についての製品使用の最初の7日間の間に対照液と少なくとも同程度に良好であることを示した。レンズタイプに無関係に、すべての被験者に対する全体の結果を線プロットで示す。図1は快適装着時間についての試験液と対照液との間の臨床比較の結果を示している。図2は挿入時のレンズの清浄性についての試験液と対照液との間の結果を示している。図3は挿入時の快適さについての試験液と対照液との間の結果を示している。図4は一日の終わりでのレンズの清浄性についての試験液と対照液との間の結果を示している。図5は一日の終わりでの快適さについての試験液と対照液との結果を示している。
16人の被験者が試験液及び対照液の各々についてドライアイ関連症状を有することが確認された。ドライアイとは、ベースライン訪問時に、目が「しばしば」又は「常に」乾燥していると感じるか又は過去にドライアイ症候群と医師から診断された人の目として定義される。表15に示す予備的な結果は、ドライアイ症状を伴う被験者では、試験液が対照液を上回っていることを示唆する。長期間分析(longitudinal analysis)を用いて、各々の日の質問について試験液と対照液との間でスコアを比較する。0のスコアは最も好ましくない等級を示しそして100のスコアは最も好ましい等級を示す。
