Abstract
Description
(i)親油性並びに両親媒性活性成分の取り込み、及び
(ii)非毒性、及び
(iii)有機溶媒の回避、及び
(iv)制御活性成分放出の可能性、及び
(v)優れた安定性(機械的及び化学的)、及び
(vi)噴霧乾燥のための使用可能性、及び
(vii)良好な光学特性(非混濁製剤の製造を可能にする)、及び
(viii)滅菌可能性
などのいくつかの重要な利点のため、こうした使用に適する。
(a)
(i)固相における脂質相と、
(ii)任意選択的に少なくとも1つの親油性及び/又は両親媒性活性成分と、
を含む核と、
(b)
(i)少なくとも1つの乳化剤
を含む乳化剤系であって、少なくとも1つのサポニンを含むことを特徴とする、乳化剤系と、
を含む固体脂質ナノ粒子(I)に関する。
この実施例の50gの試料重量は、90重量%の界面活性剤(キラヤ抽出物、0.6重量%)/リン酸ナトリウム緩衝液(10mM、pH=7)及び10重量%のトリパルミチン酸グリセリルからなる。トリパルミチン酸グリセリルは、完全に脂質を溶融させるために85℃まで加熱した。同一温度(85℃)で界面活性剤緩衝液を別に加熱した後、脂質溶融物及び界面活性剤水相をともに混合し、ホモジナイザー標準装置(homogenizer standard unit)(Labworld−online、独国シュタウフェン)を使用することによって、1分間撹拌した。キラヤ抽出物の含有量は、試料の総重量に基づいて、0.54重量%であった。こうして形成した加熱プレミックスを、高圧ホモジナイザー(EmulsiFlex−C3,AvestinInc.、カナダ国オタワ)によって10.000psi(約700バール)で5回、乳化物を通すことによって、直接均質化した。均質化に先立って、高圧ホモジナイザーを、機械を通して5回沸騰水を循環することによって加熱し、乳化物の結晶化を防止した。均質化の際、すでに均質化した試料をフラスコに収集し、これを水浴中に置いた。次いで、微細乳化物を2つの部に分け、これを、1時間、氷浴中で保存して油脂の結晶化を誘発した。その後、2つの分散部を、それぞれ7℃又は25℃で保存した。
キラヤ抽出物の含有量が、試料の総重量に基づいて、3.24重量%まで増加した以外は、実施例2を実施例1と同様に行った。
界面活性剤溶液が、それぞれ4:1の比でホスファチジルコリンとキラヤ抽出物の混合物を含む以外は、実施例3を実施例1と同様に行った。試料の総重量に基づいて、2.7重量%(キラヤ0.54重量%とホスファチジルコリン2.16重量%のものである)である界面活性剤の総量の含有量。
実施例1〜3に記載のすべての試料の物理的安定性を、3週間の期間にわたり測定した(7℃で)。
3.3%の界面活性剤−共界面活性剤水溶液を、1.5gの80Hホスホリポンレシチン及び1.5gのキラヤ抽出物を87gの10mMナトリウムリン酸緩衝液(pH=7)において混合し調製した。こうして生成した界面活性剤溶液を、振動水浴において、30分間、85℃まで加熱した。別に、10gのトリステアリン酸グリセリンを、完全に脂質を溶融させるために85℃まで加熱し、0.005gのβ−カロテン活性物を、封止され80℃で30〜60分間、暗所で撹拌された(200rpm)脂質溶融物に加え、活性物の溶解を可能にした。加熱した脂質相を、80℃に維持された界面活性剤水溶液と混合し、24000/分で2分間、ホモジナイザー標準装置によって撹拌して、粗い乳化物を生成した。キラヤ抽出物及びレシチン両方の含有量は、試料の総重量に基づいて、1.5重量%であった。次いで、加熱したプレミックスを、微細流動装置(H−チャンバ、500バール、4サイクル)を使用して均質化し、最終乳化物を生成した。微細流動装置及びチャンバを、均質化の前に熱水を用いて加熱して、乳化物の結晶化を防止した。収集した微細乳化物を、1時間、氷浴中で保存して油脂の結晶化を誘発した。その後、分散物を室温で暗所にて保存した。SLNにおけるカプセル化したβ−カロテンの含有量は、試料の総重量に基づいて、0.005重量%であった。
異なる活性物を用いた以外は、実施例4と同一の条件を使用した。ビタミンAアセテートを、β−カロテンと同様に処理した。
実施例4及び5に記載の試料の物理的安定性を、3週間の期間にわたり測定した(7℃及び25℃で)。
