Description
Verfahren zur Herstellung nicht giftiger, stark bakterizider Cerlösungen. Den Gegenstand des vorliegenden Patentes bildet die Herstellung ungiftiger, stark bakterizider Cerlösungen für parenterale Verwendung.Process for the production of non-toxic, strongly bactericidal cerium solutions. The subject of the present patent is the production of non-toxic, strong bactericidal cerium solutions for parenteral use.
Es ist bekannt, daß Cerlösungen starkgiftig sind und daß sie sich nicht ohne Gewebezerstörung intravenös oder intramuskulär einführen lassen.It is known that cerium solutions are highly toxic and that they are do not allow intravenous or intramuscular insertion without tissue destruction.
Anderseits liegt ein erhebliches Interesse vor, Cerlösungen in einer Form zu gewinnen, die es gestattet, sie in dieser Weise in den Organismus einzuführen, da die bisherigen Erfahrungen auf diesem Gebiete vermuten ließen; daß pathologisch veränderten Zellgeweben eine gewisse selektive Anlagerungsfähigkeit für Cerverbindungen zukäme.On the other hand, there is considerable interest in cerium solutions in one To obtain a form that allows it to be introduced into the organism in this way, as previous experiences in this area suggested; that pathological modified cell tissues have a certain selective attachment capacity for cerium compounds would come.
Es wurde nun gefunden, daß Cersalze und Cerhalogenide, insbesondere Cerjodür, praktisch völlig entgiftet werden können, wenn ihre Lösungen mit Lösungen von neutralen Salzen, insbesondere Kochsalz, in der Weise vereinigt werden, daß beide Lösungen gegeneinander isotonisch sind.It has now been found that cerium salts and cerium halides, in particular Cerjodür, can be practically completely detoxified if your solutions with solutions of neutral salts, especially table salt, are combined in such a way that both solutions are isotonic to one another.
Die Toxilität der Cersalze ist mehrfach nachgeprüft worden (F r ä n c k e 1, Arzneimittelsynthese 1912). Die letate Dosis liegt etwa bei o,oo5 g pro Kilogramm Körpergewicht (auf C eroxyd berechnet). Demgegenüber wurde festgestellt, daß bei Cersalz im isotonischen Gemisch mit neutralen Salzen, also z. B. einem isotonischen Gemisch von Cerjodür und Kochsalz, diese letate Dosis auf das 36- bis 23ofache überschritten werden konnte, so daß der Einführung von Cersalzen in den Körper durch Beseitigung des Hindernisses der hohen Toxicität der Weg freigemacht ist.The toxicity of cerium salts has been checked several times (F r ä n c k e 1, Drug Synthesis 1912). The letate dose is about 0.05 g per Kilograms of body weight (calculated in terms of cerium oxide). In contrast, it was found that with cerium salt in an isotonic mixture with neutral salts, so z. B. an isotonic Mixture of cerium iodine and table salt, this letate dose exceeded 36 to 23 times Could be so that the introduction of cerium salts into the body through elimination the way is cleared for the obstacle of high toxicity.
Das Verfahren wird, wie folgt, ausgeführt: Es werden z. B. 0,2611 g reines Kochsalz in iooccm redestilliertem Wasser gelöst undmit einer Lösung von 2,3259 g Cerjodürin ioo ccm ebenfalls redestilliertem Wasser versetzt und zwecks Sicherung der Sterilität noch etwa 4 5 bis 6o Minuten auf eine Temperatur von 6o bis 65° erwärmt. Diese Temperatur genügt einerseits, um die Sterilität der Lösung zu sichern, da dieser eine starke bakterizide Wirkung zukommt, anderseits darf diese Temperatur nicht überschritten werden, da insbesondere bei dem Paar Cerjodür-Kochsalz über 655 Umsetzungen stattfinden, die das Präparat für Injektionszwecke unbrauchbar machen. Zweckmäßig wird die Mischung der isotonisch aufeinander eingestellten Lösungen auf den osmotischen Druck von einer Atmosphäre eingestellt. Selbstverständlich kann, besonders für solche Fälle, wo der Verbraucher in der Lage ist, genaue Verdünnungen vorzunehmen, auch die Einstellung auf das Mehrfache einer Atmosphäre erfolgen, um einen bequemeren Versand und eine Vermeidung größerer zu transportierender Flüssigkeitsmengen herbeizuführen.The method is carried out as follows. B. 0.2611 g of pure table salt dissolved in 10 ounces of redistilled water and mixed with a solution of 2.3259 g Cerjodürin ioo ccm also redistilled water added and for the purpose Ensuring sterility for another 4 5 to 6o minutes at a temperature of 6o heated to 65 °. On the one hand, this temperature is sufficient to ensure the sterility of the solution to ensure, as this has a strong bactericidal effect, on the other hand, this is allowed Temperature must not be exceeded, especially in the case of the pair of cerium iodine table salt Over 655 conversions took place, which made the preparation unusable for injection purposes do. The mixture of the isotonic solutions adjusted to one another is expedient adjusted to the osmotic pressure of one atmosphere. Of course, especially for those cases where the consumer is able to use precise dilutions to make, even the adjustment to be made to multiples of an atmosphere more convenient shipping and avoidance of large amounts of liquid to be transported bring about.
Es ist hervorzuheben, daß trotz der Entgiftung der Cersalze ihre therapeutische Wirksamkeit nicht vermindert oder zerstört ist. Sie hat sich wirksam erwiesen in der Beeinflussung septischer Herde, von Tumoren, von iiltrierbaren Virusarten, Trypanosomen u. dgl.It should be emphasized that despite the detoxification of the cerium salts, their therapeutic properties Effectiveness is not diminished or destroyed. It has been shown to be effective in the influence of septic foci, tumors, filterable virus types, trypanosomes and the like
