Description

  • Verfahren zur Herstellung haltbarer wässeriger, therapeutisch verwendbarer Lösungen der Polyoxyalkylisoalloxazine Zusatz zum Patent 686 793 Das Patent 686 793 betrifft ein Verfahren, haltbare Lösungen der in Wasser nur schwer löslichen Polyoxyalkylisoalloxazine zu gewinnen durch die Verwendung von Mono-N-alkylderivaten der Amide niederer Fettsäuren als Lösungsmittel bzw. als Lösungsvermittler.Process for making durable aqueous, therapeutically useful Solutions of the polyoxyalkylisoalloxazines Addition to patent 686 793 The patent 686 793 relates to a method of preserving stable solutions that are only sparingly soluble in water Polyoxyalkylisoalloxazines can be obtained through the use of mono-N-alkyl derivatives of the amides of lower fatty acids as solvents or as solubilizers.
  • Bei der weiteren Bearbeitung hat sich gezeigt, daß man mit Vorteil auch die Salze von Phenol- bzw. Polyphenolsulfonsäuren als Lösungsvermittler verwenden kann. Schon bei verhältnismäßig geringen, z. B. 5 °/0 betragenden Konzentrationen der Salze von Phenol-bzw. Polyphenolsulfonsäuren lassen sich Lösungen erzielen, die im Vergleich zu wässerigen Lösungen einen mehrfachen Gehalt an Polyoxyalkylisoalloxazinen aufweisen. Die Lösungen können gleichzeitig mit anderen geeigneten Lösungsvermittlern, wie Fettsäurealkylamiden, Harnstoffen, Sarkosinanhydrid u. dgl., versetzt werden. Das beschriebene Verfahren eignet sich besonders zur Herstellung therapeutisch anwendbarer Lösungen des Lactoflavins. Further processing has shown that it is advantageous also use the salts of phenol or polyphenol sulfonic acids as solubilizers can. Even with relatively small, z. B. 5% concentrations the salts of phenol or. Polyphenolsulfonic acids can be used to achieve solutions which, compared to aqueous solutions, has a multiple content of polyoxyalkylisoalloxazines exhibit. The solutions can be used simultaneously with other suitable solubilizers, such as fatty acid alkylamides, ureas, sarcosine anhydride and the like. The method described is particularly suitable for producing therapeutically applicable ones Lactoflavin solutions.
