Description
Verfahren zur Herstellung eines Insulinpräparates. Gegenstand des vorliegenden Patentes ist ein Verfahren zur Herstellung eines Insulin- präparates. Das Verfahren ist dadurch ge kennzeichnet, dass ein Insulinsalz und Cy- prinin in saurer Lösung miteinander in Re aktion gebracht werden, wodurch Cyprinin- insulinat gebildet wird.
Bei der Durchführung der Reaktion ist es vorteilhaft, die Gewichtsmenge des Protamins so zu bemessen, dass sie etwa i/3 bis '/" der Gewichtsmenge des Insulinsalzes beträgt.
Zu bemerken ist, dass die Reaktion, wie sich zeigte, bereits bei gewöhnlicher Tem peratur stattfindet und sehr schnell vor sich geht. Dabei wird der saure Rest des Insulin salzes abgespalten.
Beispiel: 10 Gewichtsteile Insulin und 1,2 Ge wichtsteile Cyprinin werden in saurer Lö sung miteinander in Reaktion gebracht.
Der Säuregrad der Lösung wird grösser gewählt als einem 1)j1-Wert von cal 4 entspricht, und die Reaktion wird bei gewöhnlicher Tem peratur ausgeführt. Infolge des genannten Säuregrades der Lösung verbleibt die bei der Reaktion gebildete neue chemische Verbin- dung (Cyprinininsulinat) in Lösung,
sie kann aber durch Erhöhung des pH-Wertes aus gefällt werden. Das Produkt ist ein in Was ser schwer lösliches, weisses und amorphes Pulver, welches sich beim. Erwärmen bei cal 100 bis 120' C zu zersetzen anfängt.
Die gebildete chemische Verbindung Prot- amininsulinat ist im pn-Wertgebiet 7 bis 7,5 sehr schwer löslich, während im Gegensatz hierzu beide Reaktionskomponenten bei die sen pH-Werten leicht löslich sind.
Die ganze Reaktionsmasse besteht nach Beendigung der rasch verlaufenden Reaktion aus einer Lösung von Protamininsulinat. Die ses Präparat wird zweckmässig in Ampullen eingefüllt, die je einen einer gewissen Anzahl internationaler Insulineinheiten entsprechen den Inhalt aufnehmen. Die Lösung _ sollte nicht als solche,
sondern erst nach Fällung durch Zusatz eines alkalisierenden Stoffes benutzt werden.
Die durch Benutzung eines solchen In sulinpräparates entstandene Wirkung in dem menschlichen Organismus wird bedeutend langsamer verlaufen und infolgedessen auch bedeutend milder sein als es bei Verwendung von Insulinhydrochlorid der Fall ist, und dieser langsamere Wirkungsverlauf bewirkt zugleich, dass die Wiederholung einer Ein spritzung erst nach einer verhältnismässig langen Zeitperiode stattzufinden braucht.
Process for the production of an insulin preparation. The subject of the present patent is a process for the production of an insulin preparation. The method is characterized in that an insulin salt and cyprinin are brought into reaction with one another in acidic solution, whereby cyprinin insulinate is formed.
When carrying out the reaction, it is advantageous to measure the amount by weight of the protamine so that it is about 1/3 to 1/ "of the amount by weight of the insulin salt.
It should be noted that the reaction, as has been shown, already takes place at normal temperature and is very rapid. The acidic remainder of the insulin salt is split off.
Example: 10 parts by weight of insulin and 1.2 parts by weight of cyprinine are brought into reaction with one another in an acidic solution.
The acidity of the solution is chosen to be greater than a 1) j1 value of cal 4, and the reaction is carried out at the usual temperature. As a result of the acidity of the solution, the new chemical compound formed during the reaction (cyprin insulinate) remains in the solution,
however, it can be precipitated out by increasing the pH. The product is a white and amorphous powder that is sparingly soluble in water. Heating at cal 100 to 120 ° C begins to decompose.
The chemical compound formed, protamine insulinate, is very sparingly soluble in the pn value range from 7 to 7.5, while in contrast to this, both reaction components are easily soluble at these pH values.
After the rapid reaction has ended, the entire reaction mass consists of a solution of protamine insulinate. This preparation is expediently filled into ampoules, each of which contains a certain number of international insulin units. The solution _ should not as such,
but can only be used after precipitation by adding an alkalizing substance.
The effect in the human organism resulting from the use of such an insulin preparation will be significantly slower and consequently also significantly milder than is the case with the use of insulin hydrochloride, and this slower course of action also means that the repetition of an injection will only take place after one takes place over a long period of time.
