Description
In neuerer Zeit haben die Wismutverbindungen in der Therapie eine erhöhte Beachtung erlangt. Für ihre zweckmäßige Anwendung sind Darreichungsformen erforderlich; welche diese Verbindungen gelöst oder in feinster Verteilung enthalten und sich für die intravenöse bzw. parenterale Injektion eignen. Für die subkutane und intramuskuläre Injektion erwiesen sich Emulsionen von unlöslichenIn recent times the bismuth compounds have received increased attention in therapy attained. Dosage forms are required for their appropriate use; which these compounds dissolved or contained in the finest distribution and are suitable for the intravenous or parenteral injection are suitable. For subcutaneous and intramuscular injection proved to be insoluble emulsions
to Wismutverbindungen als besonders vorteilhaft.to bismuth compounds as particularly advantageous.
Es wurde nun gefunden, daß man haltbare,It has now been found that durable,
ölige Emulsionen von Wismutsalzen durch Auflösung der Wismutsalze von Fettsäuren in geeigneten organischen Lösungsmitteln, Vermischen dieser Lösungen mit einem Öl und Ab destillieren des organischen Lösungsmittels erhält. Die auf diese Weise gewonnenen Emulsionen zeigen selbst nach längerem Stehen keine Abscheidungen. Sie enthalten die Wismutverbindungen stets in feinster Verteilung, welche bedingt, daß die Emulsionen leicht injizierbar sind und gut resorbiert werden. oily emulsions of bismuth salts by dissolving the bismuth salts of fatty acids in suitable organic solvents, mixing these solutions with an oil and From distilling the organic solvent is obtained. The ones obtained in this way Emulsions show no deposits even after standing for a long time. They contain the Bismuth compounds always in the finest distribution, which means that the emulsions are easily injectable and well absorbed.
Für die Herstellung der Emulsionen eignen sich besonders die Wismutsalze der höheren Fettsäuren. Als Emulgierungsmittel kann man sowohl die natürlich vorkommenden Öle als auch synthetische Fettsäureester und mineralische Öle verwenden.The bismuth salts of the higher ones are particularly suitable for the production of the emulsions Fatty acids. Both naturally occurring oils and also use synthetic fatty acid esters and mineral oils.
Durch die Patentschrift 246507 ist ein Verfahren zur Herstellung von Lösungen von Quecksilbersalzen in Ölen und Fetten bekannt geworden, welches darin besteht, daß man diese Salze in einem flüchtigen Lösungsmittel löst, die Lösung mit Fett mischt und schließlieh das flüchtige Lösungsmittel entfernt. Gegenüber dem vorliegenden Verfahren unterscheidet sich dasselbe zunächst darin, daß es sich auf Quecksilbersalze bezieht. Dann aber sollen damit Lösungen von Quecksilbersalzen in Ölen und Fetten gewonnen werden, während im vorliegenden Falle das Ziel die Herstellung haltbarer Emulsionen ist. Aus dem Verfahren der Patentschrift 246507, d.h. aus dem Verhalten der Quecksilbersalze, welche sich in Ölen und Fetten lösen, konnte nicht geschlossen werden, daß Wismutsalze haltbare Emulsionen abgeben.By the patent specification 246507 a method for the preparation of solutions of Mercury salts in oils and fats have become known, which consists in the fact that one dissolve these salts in a volatile solvent, mix the solution with fat and finally the volatile solvent removed. Compared to the present procedure differs the same is first in the fact that it relates to mercury salts. But then so that solutions of mercury salts in oils and fats are obtained while in the present case the aim is to produce long-lasting emulsions. From the proceedings of patent specification 246507, i.e. from the behavior of the mercury salts, which are in Dissolving oils and fats, it could not be concluded that bismuth salts are durable emulsions hand over.
Man löst 1 Gewichtsteil Wismutoleat in 10 bis 15 Gewichtsteilen Äther. Die mit geglühtem Glaubersalz getrocknete und filtrierte Lösung mischt man mit 4 Teilen Olivenöl und destilliert den Äther zuerst bei gewöhnlichem Druck, später im Vakuum ab. An Stelle von Olivenöl kann auch Mandelöl oder Paraffinöl verwendet werden. Man erhält weiße, ziemlich dickflüssige, haltbare Emulsionen mit einem Wismutgehalt von 4 Prozent.1 part by weight of bismuth oleate is dissolved in 10 to 15 parts by weight of ether. The ones with annealed Glauber's salt, dried and filtered solution, is mixed with 4 parts of olive oil and the ether is first distilled with ordinary Pressure, later in a vacuum. Almond oil or paraffin oil can also be used instead of olive oil. You get white, rather thick, durable emulsions with a bismuth content of 4 percent.
