Description
Verfahren zur Herstellung einer Suppositoriengrundmasse.
Die rektale Verabreichung von lleilmitteln bietet gegenüber der parenteralen Applikation in vielen Fällen grosse Vorteile. Sie stösst aber oft auf Schwierigkeiten, da viele Stoffe vom Rektum oder von der Vagina aus nicht oder ungenügend resorbiert werden und daher keine Wirkung entfalten können.
Es wurde nun gefunden, dass man die Resorption dieser Stoffe vom Darm oder von der Vagina aus ermöglichen oder wesentlich steigern kann, wenn man der Suppositoriengrundmasse gallensaure Salze zusetzt. Selbstverständlich kann man auch Galle selbst hinzufügen, da diese gallensaure Salze enthält. Gallensäuren und Galle wirken in grö sserer Menge abführend. Überraschenderweise genügen aber für die Resorption schon Mengen, die diese Wirkung nicht hervorrufen.
Es ist bekannt, dass Gallensäuren eine wichtige Rolle bei der Fettresorption spielen. Die Tatsache aber, dass die Gallensäuren die Resorption auch von zum Beispiel an sich wasserlöslichen und dennoch unresorbierbaren Stoffen bewirken können, ist völlig neu und bedeutet einen neuen Fortschritt für die Therapie.
Die Anwendung der neuen Suppositoriengrundmasse gibt erstmals die Möglichkeit, wie viele Versuche an Tieren und am Men schen zeigten, z. B. lösliche Quecksilberkom plexverbindungen und auch Hormone rektal oder vaginal zur Wirkung zu bringen. Queck silberkouiplexverbindungen werden sonst rektal oder vaginal nicht resorbiert oder aber die Reaktion muss zur Resorption so stark alkalisch gehalten werden, dass die Schleimhaut des Rektums oder der Vagina zu sehr angegriffen wird. Dank dem Zusatz von zum Beispiel einer kleinen Menge desoxycholsaurem Natrium kann man Suppositorien mit einem Quecksilberdiureticum herstellen, die bei neutraler Reaktion ausgezeichnete Wirkung entfalten.
Sogar Insulin mit einer dem Einweiss nahekommenden Molekelgrösse kann mittels der neuartigen Suppositoriengrundmasse. zur Resorption gebracht werden, wobei die langsamere Resorption im Vergleich zu der bei subkutaner Injektion therapeutisch nur erwünscht ist.
Die neuartige Suppositoriengrundmasse kann insbesondere auch vorteilhaft mit solchen Arzneimitteln verarbeitet werden, die an sich wasserlöslich sind, aber dennoch nicht oder nur schmier resorbiert werden.
Beispiel 1:
100 g Cacaobutter werden unter Zusatz von 10 g Wachs geschmolzen. In die Schmelze trägt man 3 Teile cholsaures Natrium ein.
Beispiel 2:
In 100 Teile geschmolzene Cacaobutter wird 1 Teil desoxycholsaures Natrium eingetragen.
Beispiel 3:
100 Teile geschmolzene Caeaobutter werden mit 3 Teilen gereinigter Galle unter Rühren zu einer homogenen Mischung verarbeitet.
Beispiel 4:
100 Teile Cacaobutter werden unter Zusatz von 5 Teilen Wachs geschmolzen und mit einer Mischung von je 2 Teilen tauro cholsaurcm und glykocholsaurem Natrium versetzt.
Beispiel 5:
100 Teile geschmolzene Cacaobutter werden mit 4 Teilen ungereinigter Galle unter Verwendung eines Emulgators und unter Riihren homogenisiert.
Beispiel 6:
12,5 Teile Gelatine, 25 Teile Wasser, 61,5 Teile Glyzerin und 1 Teil desoxycholsaures Natrium werden vermischt.
Process for making a suppository base.
The rectal administration of oils offers great advantages over parenteral administration in many cases. However, it often encounters difficulties, since many substances are not or insufficiently absorbed from the rectum or vagina and therefore cannot develop any effect.
It has now been found that the absorption of these substances from the intestine or the vagina can be made possible or significantly increased by adding bile acid salts to the suppository base. Of course, you can also add bile yourself, as it contains bile-acid salts. Bile acids and bile have a laxative effect in larger quantities. Surprisingly, however, quantities that do not produce this effect are sufficient for absorption.
It is known that bile acids play an important role in fat absorption. The fact, however, that the bile acids can also effect the absorption of, for example, water-soluble and non-absorbable substances, is completely new and represents a new advance in therapy.
The application of the new suppository base material gives the first time the possibility, as many tests on animals and people showed, z. B. to bring soluble Mercury Complex compounds and hormones rectally or vaginally to effect. Mercury complex compounds are otherwise not absorbed rectally or vaginally, or the reaction must be kept so strongly alkaline for absorption that the mucous membrane of the rectum or vagina is attacked too much. Thanks to the addition of, for example, a small amount of sodium deoxycholic acid, suppositories can be made with a mercury diuretic, which have an excellent effect in a neutral reaction.
Even insulin with a molecule size that comes close to protein can be used with the new suppository base. be brought to absorption, the slower absorption compared to that with subcutaneous injection is only therapeutically desirable.
The novel suppository base can, in particular, also advantageously be processed with drugs that are inherently water-soluble, but are nevertheless not or only poorly resorbed.
Example 1:
100 g cocoa butter are melted with the addition of 10 g wax. 3 parts of sodium cholate are introduced into the melt.
Example 2:
1 part of sodium deoxycholate is added to 100 parts of melted cocoa butter.
Example 3:
100 parts of melted Caeao butter are mixed with 3 parts of purified bile while stirring to form a homogeneous mixture.
Example 4:
100 parts of cocoa butter are melted with the addition of 5 parts of wax and mixed with a mixture of 2 parts each of taurocholic acid and sodium glycolate.
Example 5:
100 parts of melted cocoa butter are homogenized with 4 parts of unpurified bile using an emulsifier and while stirring.
Example 6:
12.5 parts of gelatin, 25 parts of water, 61.5 parts of glycerol and 1 part of sodium deoxycholic acid are mixed.
