Definitions
- the present invention relates to a peritoneal dialysis solution containing icodextrin.
- Peritoneal dialysis which is one of the symptomatic treatments for renal failure, is one of the home medical treatments because it requires less equipment and instruments and less time constraints than dialysis performed by artificial kidneys.
- Many peritoneal dialysates currently in use use glucose as an osmotic substance.
- Glucose has the advantage of being relatively safe and inexpensive, but because of its low molecular weight, it is rapidly absorbed from the peritoneum and cannot provide a continuous water removal effect. From the above situation, a search for an osmotic substance instead of glucose capable of maintaining ultrafiltration during long-time storage has been conducted, and it has been found that icodextrin, a glucose polymer, is suitable for peritoneal dialysis fluid.
- Icodextrin has a large molecular weight, so it is not absorbed rapidly through the peritoneum, but acts mainly as a colloid osmotic substance, and can obtain a water removal effect while maintaining the osmotic pressure with plasma. .
- peritoneal dialysis fluids that use icodextrin are formulated so that the drug solution is in the range of pH 5.0 to 5.5 in order to prevent decomposition and coloring of icodextrin.
- the pH of the peritoneal dialysis fluid has a great influence on the stability of icodextrin. If the pH is increased as it is, the icodextrin is decomposed into glucose during production and storage, and the peritoneal dialysis fluid is degraded due to the deterioration of the glucose. Coloring will result in a significant reduction in product value. That is, the absorbance at 284 nm, which is an indicator of 5-hydroxymethylfurfural, which is the main degradation product of glucose, increases over time. Further, when the pH is increased, the absorbance at 228 nm, which is an index of 3-deoxyglucosone, which is a main degradation product of glucose, also increases depending on the pH. Furthermore, there is a method of raising the pH using a carbonate such as sodium hydrogen carbonate, but calcium and magnesium react with carbonic acid under alkalinity to cause precipitation.

Abstract
Description
イコデキストリンは、分子量が大きいため、腹膜を介して急速に吸収されることもなく、主として膠質浸透圧物質として作用し、血漿との浸透圧を維持しながら除水効果を得ることが可能である。現在、イコデキストリンを使用している腹膜透析液は、イコデキストリンの分解・着色を防止するため、薬液がpH5.0~5.5の範囲になるように処方される。
イコデキストリンを含有する酸性の第1液と、300~3000mg/LのL-ヒスチジン及びpH調整剤を含有する第2液とからなる滅菌された腹膜透析液であって、滅菌後に第1液と第2液を混合した後のpHが6.7~7.5である腹膜透析液。
第1液の塩化ナトリウムの含有量は、1.42~2.34g/L、好ましくは、1.85~2.15g/Lである。塩化ナトリウムは、浸透圧を調整する目的で配合され、第1液の塩化ナトリウムの含有量が2.34g/Lを超えると、イコデキストリンから生じるブドウ糖分解生成物の量が多くなり好ましくない。
本発明の腹膜透析液において、滅菌後の第2液は、中性からアルカリ性領域であり、具体的には、pH6.7~8.0の範囲が好ましく、pH6.7~7.5の範囲がより好ましい。pHが6.7未満および8.0を超えると、混合後のpHが6.7~7.5にならないため、好ましくない。
上記のpHは、pH調製剤により調整することができる。pH調整剤としては、一般的に使用されている乳酸ナトリウム、クエン酸三ナトリウム、リン酸三ナトリウムなどが使用できるが、水酸化ナトリウム及び炭酸水素ナトリウムは使用しない。
本発明において、第2液は、塩化ナトリウム、乳酸ナトリウム、塩化カルシウムおよび塩化マグネシウムの少なくとも一つを含有する。これらの成分の量は、特に限定はなく、通常の腹膜透析液と同様の量が含まれていればよく、好ましくは、塩化ナトリウムが16.6~347.8g/L、乳酸ナトリウムが21.3~448.0g/L、塩化カルシウムが1.22~25.7g/L、および塩化マグネシウムが0.24~5.10g/Lである。これらの成分は、イコデキストリンから生じるブドウ糖分解生成物の量を抑制する観点から、塩化ナトリウム以外はイコデキストリンを含まない第2液に配合するのが好ましい。
特に、本発明の腹膜透析液は、医療用袋体であって、その内部を開放可能な仕切手段によって分離されることにより形成される第1室と第2室とを有し、第1室には医療用袋体の内外を連通する排出ポートを有するものに、第1液と第2液とを分離して収納されることが好ましい。
以上、本発明の腹膜透析液について詳細に説明したが、本発明は、これに限定はされず、本発明の要旨を逸脱しない範囲において、各種の改良および変更を行ってもよい。
