Description
Verfahren zur Herstellung einer Suppositorienmasse Die Herstellung von Suppositorien aus einem hochmolekularen Polyäthy lenoxyd mit einem Schmelzpunkt von 50 bis 600 ist bekannt. Es wurde nun gefunden, daß man ein bei Körperwärme schmelzendes I Polyäthylenoxyd herstellen kann, das die völlige Wasserlöslichkeit des hochschmelzenden Produktes mit einer vorzüglich emulgierenden Wirkung verbindet, die die in der Suppositorienmasse verteilten Substanzen noch rascher und leichter zur Wirkung kommen läßt.Method of making a suppository mass The manufacture of suppositories made of a high molecular weight Polyäthy lenoxyd with a melting point from 50 to 600 is known. It has now been found that one which melts at body heat I can produce polyethylene oxide, which ensures the complete water solubility of the high-melting point Product with an excellent emulsifying effect, which combines that in the suppository mass distributed substances can take effect even more quickly and easily.
Das Verfahren besteht darin, daß zunächst Glykol in Gegenwart von Ätzkali bei erhöhter Temperatur mit Äthylenoxyd umgesetzt wird. Darauf wird nach Zusatz von Natriumalkoholat nochmals Äthylenoxyd eingeleitet, bis ein bei Körperwärme schmelzendes Reaktionsprodukt entsteht. The method consists in that first in the presence of glycol Caustic potash is reacted with ethylene oxide at elevated temperature. This is followed by Addition of sodium alcoholate again introduced ethylene oxide until one at body heat melting reaction product is formed.
Da das Produkt bei der Lagerung je nach der Raumtemperatur und der Luftfeuchtigkeit wechselnde Mengen Wasser aufnimmt und dabei ein absinken des Schmelzpunktes eintritt, ist es zweckmäßig, die Reaktion so zu führen, daß zunächst ein Produkt mit einem höheren Schmelzpunkt entsteht, der dann erst bei der Verarbeitung der Masse durch Zusatz von Wasser auf die gew ünschte Höhe (Körpertemperatur) eingestellt wird. Dazu sind je nach der Lage der Schmelzpunkte 2 bis 8 O/o Wasser notwendig. As the product depends on the room temperature and the Humidity absorbs varying amounts of water and thereby a decrease in the melting point occurs, it is advisable to conduct the reaction so that first a product with a higher melting point, which only occurs when the The mass is adjusted to the desired height (body temperature) by adding water will. For this, 2 to 8% water are necessary, depending on the position of the melting points.
Beispiel I00 Gewiclltsteile Glykol werden in der üblichen Weise in Gegenwart von 0,5 Teilen Ätznatron bei I500 und I atü mit 400 Teilen Äthylenoxyd umgesetzt. Nach Zusatz von 10 Teilen Natriummethylatlösung werden unter den gleichen Be- dingungen nochmals I400 Teile Äthylenoxyd eingeleitet. Alan erhält etwa I800 Teile eines Reaktionsproduktes, das bei 380 schmilzt. Example 100 parts by weight of glycol are used in the usual manner in Presence of 0.5 parts of caustic soda at 1500 and I atü with 400 parts of ethylene oxide implemented. After adding 10 parts of sodium methylate solution are among the same Loading conditions initiated again I400 parts of ethylene oxide. Alan receives about 1800 parts of a reaction product that melts at 380.
Die Verarbeitung des Reaktionsproduktes auf Suppositorienmasse geschieht in bekannter Weise durch Aufschmelzen, Zumischen der erforderlichen Aledikamente, Ausgießen in Formen und Erstarrenlassen. The processing of the reaction product is done on suppository mass in a known way by melting, mixing in the required aledicaments, Pour into forms and solidify.
