Description
本発明は、アムホテリシンＢと脂肪酸ポリエチレングリコールとを含有する水に可溶な固形組成物および水性組成物、並びにそれらの製造方法に関する。
The present invention relates to a water-soluble solid composition and an aqueous composition containing amphotericin B and fatty acid polyethylene glycol, and methods for producing them.
アムホテリシンＢは、ポリエン系抗生物質のひとつであって水に極めて難溶性であり、服用しても生体内への吸収性が極めて低いなどの短所を有するが、その優れた薬効のため深在性真菌感染症に対する治療価値の高い注射剤として、また、その生体への低い吸収性を利用して消化管内（胃腸内）におけるカンジダの異常増殖に対する錠剤およびシロップ剤として用いられている。
Amphotericin B is one of the polyene antibiotics and is extremely poorly soluble in water and has the disadvantage that it is very poorly absorbed into the body even when taken. It is used as an injection with high therapeutic value for fungal infection, and as a tablet and syrup for the abnormal growth of Candida in the digestive tract (in the gastrointestinal tract) due to its low absorbability to the living body.
脂肪酸ポリエチレングリコールは、界面活性剤であり、それにはポリエチレングリコール部分の重合度が異なる多数の化合物が存在する。
Fatty acid polyethylene glycol is a surfactant, and there are many compounds with different degrees of polymerization of the polyethylene glycol moiety.
アムホテリシンＢを有効成分とする注射用製剤として、例えば「ファンギゾン（登録商標）注射用５０ｍｇ」、「アムビゾーム（登録商標）点滴静注用５０ｍｇ」が知られているが、いずれも他の注射剤と混合すると配合変化するため、その使用には一定の制約が設けられている(非特許文献１、２)。また、院内調剤などにおいてこれらの注射剤を他の注射剤と混合する場合、通常、感染リスク低減の目的で孔径０．２２μｍのフィルターを用いて濾過滅菌を行うが、ファンギゾン注射用５０ｍｇについては孔径０．２２μｍのフィルターを用いて濾過滅菌することはできず、また、アムビゾーム点滴静注用５０ｍｇについても孔径０．２２μｍのフィルターを用いて濾過滅菌することはできない。
As an injectable preparation containing amphotericin B as an active ingredient, for example, “Fungisone (registered trademark) 50 mg for injection” and “Ambisome (registered trademark) intravenous infusion 50 mg” are known. Since mixing changes when mixed, certain restrictions are imposed on its use (Non-Patent Documents 1 and 2). In addition, when these injections are mixed with other injections in hospital preparations, etc., it is usually sterilized by filtration using a filter with a pore size of 0.22 μm for the purpose of reducing the risk of infection. It cannot be sterilized by filtration using a 0.22 μm filter, and 50 mg for ambisome intravenous infusion cannot be sterilized by filtration using a filter having a pore diameter of 0.22 μm.
また、ファンギゾン注射用には可溶化剤としてデオキシコール酸が含まれているため、これを使用する場合にはその強力な界面活性作用に起因する強い粘膜刺激性や溶血性などが問題となっている（非特許文献３）。
特許文献１には、アムホテリシンＢなどの難溶性薬物を高圧ホモジナイザーを用いてナノオーダーサイズに微粒子化することを特徴とする微粒子分散液の製造方法に関する発明が記載されているが、この微粒子分散液においてアムホテリシンＢが溶解しているわけではない。 In addition, since deoxycholic acid is included as a solubilizer for fungizone injection, strong mucosal irritation and hemolysis due to its strong surface-active action become a problem when it is used. (Non-patent Document 3).
Patent Document 1 describes an invention relating to a method for producing a fine particle dispersion characterized in that a sparingly soluble drug such as amphotericin B is micronized to a nano-order size using a high-pressure homogenizer. However, amphotericin B is not dissolved.
