Description

Herstellung von haltbaren flüssigen Suspensionen wasserlöslicher Antimonverbindungen Für therapeutische Zwecke ist es oft erwünscht, ein wasserlösliches Antimonpräparat in einer öligen. Suspension zu injizieren und so ein Depot zu setzen, von dem aus das wasserlösliche Salz langsam von den Gewebesäften aufgenommen wird, parallel mit der Relsorption des öligen Vehikels. Verwendet man hierzu die leicht resorbierbaren fetten Öle, wie Olivenöl, Sesamöl, Mohnöl, Mandelöl, Erdnußöl usw., so stößt die praktische Durchführung der öligen Verabreichung auf das Hindernis, daß solche 5 Suspensionen mehr oder weniger rasch absetzen. Nach einigem Stehen sitzt das Metallpräparat als fester Kuchen am Boden, und die Suspension kann nur mit großer Mühe durch langes Schütteln wieder homogenisiert werden, soweit das Aufbewahrungsgefäß das nötige energische Schiitteln überhaupt zuläßt.Production of durable liquid suspensions of water-soluble antimony compounds For therapeutic purposes it is often desirable to use a water soluble antimony preparation in an oily. To inject suspension and thus to put a depot from which the water-soluble salt is slowly absorbed by the tissue juices, in parallel with the absorption of the oily vehicle. The easily absorbable ones are used for this purpose fatty oils, like olive oil, sesame oil, poppy seed oil, almond oil, peanut oil etc., so the bumps practical implementation of oily administration to the obstacle that such 5 Withdraw suspensions more or less quickly. After standing for a while, the metal preparation is in place as a firm cake on the bottom, and the suspension can only with great effort through long Shake to be homogenized again, as far as the storage vessel has the necessary allows energetic shitting at all.

Es wurde gefunden, daß man zu haltbaren, flüssigen, injizierbaren Suspensionen wasserlöslicher Antimonverbindungen in Ölen gelangen kann, wenn man die Antimonverbindungen in einem fetten Öl, dem Wollfett zugesetzt ist, suspendiert. Die Menge des Zusatzes ist bedingt durch zwei Forderungen: I. die Suspension muß sich gut in der Schwebe halten 2, die Konsistenz muß so sein, daß die Suspension bei gewöhnlicher Temperatur die Injektionsnadel gut passiert. It has been found that you can get to durable, liquid, injectable Suspensions of water-soluble antimony compounds in oils can get if one the antimony compounds are suspended in a fatty oil to which wool fat is added. The amount of additive depends on two requirements: I. The suspension got to keep yourself in suspension 2, the consistency must be such that the suspension Passes the injection needle well at ordinary temperature.

Auf diesem Wege lassen sich allgemein, vornehmlich für die Injektionstherapie bestimmte wasserlösliche Antimonverbindungen in haltbare hochprozentige Suspensionen bringen, die bei der Injektion gut vertragen und vom gesetzten Depot aus gut resorbiert werden. Auch bei anderen Verabreichungsarten, z.B. innerlich, werden sie gut resorbiert. In this way you can generally, primarily for injection therapy certain water-soluble antimony compounds in long-lasting high-percentage suspensions that are well tolerated by the injection and are well absorbed from the depot will. They are also well absorbed with other types of administration, e.g. internally.

Mit den gemäß vorliegender Erfindung erhältlichen Suspensionen sind vielfach therapeutische Vorteile verbunden. So gelingt es, z. B. mit der nach Beispiel 2 hergestellten Suspension des Antimon-V-gluconsauren Natriums den experimentellen Kalaazar des Hamsters mit einer Injektion zu heilen, während bei Behandlung mit der wäßrigen Lösung dieses Produkts hierzu etwa 8 bis 10 1 ujektionen erforderlich sind. With the suspensions obtainable according to the present invention are multiple therapeutic benefits associated with it. So it succeeds, for. B. with the example 2 prepared suspension of the antimony-V-gluconic acid sodium the experimental Cure Kalaazar's hamster with an injection while with treatment with The aqueous solution of this product requires about 8 to 10 injections are.

Es ist bekannt, daß man stabile ölige Suspensionen des gonadotropen Hypophysenvorderlappenhormons mit Hilfe eines Wollfettzusatzes herstellen kann. Hierbei handelt es sich iedoch, im Gegensatz zu Antimonverbindung, um spezifisch leichte Präparate. Diese wurden sogar, um ihr spezifisches Gewicht weiter zu vermindern, vor der suspendierung weitgehend salzfrei gemacht. Es sind auch bereits Suspensionen von Dioxydiaminoarsenobenzol in sesamöl mit Wollfettzusatz bekanntgeworden. Solche Suspensionen in Sesamöl bewährten sich jedoch nicht. Man ging daher dazu über, Diaminodioxyarsenobenzol mit einem jodierten Öl und Wollfett zu einer bei Zimmertemperatur starren Salbe zu verarbei= tell. Infolge der Starrheit der Masse kann ein Absetzen des spezifisch schweren Anteils nicht eintreten; erst durch Überführung in die Salbenform wird ein genügender Oxydationsschutz der Arsenverbindung erreicht. It is known that stable oily suspensions of the gonadotropic Can produce anterior pituitary hormone with the help of a wool fat additive. However, in contrast to antimony compounds, this is specific light preparations. In order to further reduce their specific weight, these were even made largely salt-free before suspension. There are already suspensions of dioxydiaminoarsenobenzene in sesame oil with added wool fat. Such However, suspensions in sesame oil did not work. It was therefore switched to diaminodioxyarsenobenzene with an iodized oil and wool fat to form an ointment that is rigid at room temperature to be processed = tell. Due to the rigidity of the mass, a settling of the specific heavy proportion do not occur; only becomes through conversion into the ointment form a sufficient protection against oxidation of the arsenic compound is achieved.
