Description

Verfahren zur Herstellung von haltbaren Arzneimittellösungen Das Patent -46 290 und das Zusatzpatent 4.47161 haben Verfahren zum Gegenstand, bei denen wasserlösliche Äther und Ester mehrwertiger Alkohole, beispielsweise die Äther des Glvcerins und des Glykols, als Lösungsmittel für Kampfer und Schlafmittel verwendet werden.Process for the production of durable drug solutions The patent -46 290 and the additional patent 4.47161 have processes for the subject in which water-soluble Ethers and esters of polyhydric alcohols, for example the ethers of glycerine and of glycol, used as a solvent for camphor and sleeping pills.

Es wurde nun festgestellt, daß die Äther drei- und mehrwertiger Alkohole ein hervorragendes Lösungsvermögen für die meisten - in Wasser nicht oder schwer löslichen - Arzneistoffe organischer Natur der verschiedensten Indikationsgebiete besitzen. Es gelingt so, haltbare und therapeutisch verwendbare konzentrierte Lösungen herzustellen. Diese Lösungen lassen sich zumeist, wenn sie nicht zu konzentriert sind, beliebig mit Wasser verdünnen.It has now been established that the ethers of trihydric and polyhydric alcohols an excellent solvent power for most - not or difficult in water soluble - medicinal substances of an organic nature in a wide variety of indications own. This makes it possible to produce long-lasting concentrated solutions that can be used therapeutically to manufacture. These solutions can mostly be found if they are not too focused can be diluted with water as required.

Man hat bereits vorgeschlagen, i # 3-Butylenglykol als Ersatz für Glycerin und Glvcerinester unter ariderem in der pharmazeutischen Industrie zu verwenden. Auch ist bereits angegeben worden, daß (slvkolmonohenz\-liither infolge seiner Löslichkeit in Wasser, Fetten und Ölen als Salbengrundlage Verwendung finden könne.It has already been suggested that i # 3 butylene glycol be used as a substitute for Glycerine and glycerine esters, among others, are used in the pharmaceutical industry. It has also already been stated that (slvkolmonohenz \ -liither as a result of its solubility can be used as an ointment base in water, fats and oils.

Endlich ist auch die Verwendbarkeit des Glycerinesters der Carbaminsäure bekanntgewesen. Aus diesen Angaben war jedoch nicht zu entnehmen, daß es mit Hilfe der Äther drei- und mehrwertiger Alkohole gelingen würde, Lösungen solcher Arzneistore organischer Natur, deren Wasserunlöslichkeit bisher ihrer parenteralen Anwendung im Wege stand, herzustellen.Finally, the glycerol ester of carbamic acid can also be used known. From this information, however, it could not be inferred that it was with help the ethers of trihydric and polyhydric alcohols would be the solution of such medicinals of an organic nature, whose insolubility in water has so far been their parenteral use stood in the way of establishing.

Beispiele i. Man löst 0,5 g 3 # 9-Diamino-7-:ithOxvacridin in io ccm Diäth_vlin unter Erwärmen auf.Examples i. Dissolve 0.5 g of 3 # 9-diamino-7-: ithOxvacridine in 10 cc of dieth_vlin with warming.

2. 20 g Dimethylaminophenyldimethylpyrazolon werden in einer Mischung von 2o g Diäthylin und 3o g Wasser gelöst.2. 20 g of dimethylaminophenyldimethylpyrazolone are in a mixture dissolved by 20 g of diethyline and 3o g of water.

3. o,5 g Acetylsalicylsäure werden in io ccm Dimethoxytrioxyhexan gelöst.3. 0.5 g of acetylsalicylic acid are dissolved in 10 cc of dimethoxytrioxyhexane solved.

4. o,2 g Diacetylaminoazotoluol werden in 4 ccm Dimethoxytrioxvhexan gelöst.4. 0.2 g of diacetylaminoazotoluene are dissolved in 4 cc of dimethoxytrioxy hexane solved.
