Description

  

  Verfahren zur Herstellung von bei Tropentemperatur beständigen  Grundmassen für Suppositorien.    Als Grundmasse für Suppositorien ver  wendet man in der Regel Kakaobutter oder  andere Fette, auch in     Mischung    mit Wachs,  Paraffin oder ähnlichen Stoffen, wobei bei  der Zusammensetzung der Mischung darauf  geachtet wird, dass der     Sehmelzpunkt    unter  Körpertemperatur bleibt. Suppositorien aus  solchen Trägermassen sind nur bedingt halt  bar. Bei höheren Temperaturen, zum Bei  spiel in den Tropen, erweichen sie, schmel  zen, verlieren ihre Form und werden dadurch  unbrauchbar.  



  Man hat bereits versucht, von der Tem  peratur unabhängige Suppositorien aus Seife,       Glyzei-in-Gelatine,    Aminen oder     Amiden    und  ähnlichen Stoffen herzustellen. Aber auch  aus solchen Stoffen hergestellte Suppositorien  haben sich in manchen Fällen nicht bewährt,  teils weil die gebildeten Stoffe beim Aufbe  wahren Wasser abgeben, so dass die Sup  positorien ihre Form verlieren und unbrauch-    bar werden, teils weil Stoffe, wie Glyzerin  oder Seife, bei den in Frage kommenden  Dosen unerwünschte Wirkungen auf die  Schleimhaut, zum Beispiel abführende Wir  kungen, haben.

   So kommen zum Beispiel  für Suppositorien bereits vorgeschlagene  Grundmassen aus 70-75 Teilen Harnstoff,       20-25%        Zucker        und        gegebenenfalls        Kakao-          butter    oder andern Zusätzen praktisch nicht  in Frage. Solche Massen sind zwar gesund  heitlich unschädlich, aber insofern nicht phy  siologisch indifferent, als sie eine stark ab  führende Wirkung ausüben. Ausserdem kann  durch diese     Abführwirkung    das Arzneimittel  teilweise oder vollkommen ausgeschieden  werden, ohne zur Wirkung zu gelangen.  



  Es wurde nun gefunden, dass man bei  Tropentemperatur beständige Grundmassen  für Suppositorien, die, wie Versuche ergaben,  frei von jeder unerwünschten Nebenwirkung  sind, dadurch herstellen kann, dass man feste,           wasserlösliche,phy        siologisch        indifferenteKohle-          hydrate,    wie z. B. Rohr-, Trauben- oder  Milchzucker, mit geschmolzenem Fett zu  einer     blasse    granuliert, die mindestens zu       70 ;\u    aus Kohlehydraten besteht. Die Ver  arbeitung der granulierten     blasse    zu Suppo  sitorien kann in     Maschinen    in der Art der  Tablettenmaschinen erfolgen.

   Darin liegt  bereits ein wesentlicher Vorteil der erfin  dungsgemässen     uriplastischen        Massen.    Die  bisher verwendeten, meist plastischen Träger  massen mussten nämlich durch Giessen oder  Pressen in     Strangform    auf die     gewünschten     Endprodukte verarbeitet werden.  



  Suppositorien aus erfindungsgemäss her  gestellten Massen sind, wie Versuche er  gaben, auch bei längerem     Aufbewahren    bei  Tropentemperatur, zum Beispiel bei 50 bis  i0  C,     formbestiindig.    Die löslichen Bestand  teile     lüsen    sich in Wasser bei Körpertempe  ratur.  



  Durch die erfindungsgemässe Trägermasse  wird weiterhin die pharmazeutische Technik  von einzuführender Kakaobutter weitgehend    unabhängig gemacht. Die Erfindung bedeutet  so auch einen erheblichen volkswirtschaft  lichen Fortschritt.  



  <I>Beispiel 1:</I>  210 Teile Traubenzucker werden mit  40 Teilen geschmolzener Kakaobutter granu  liert.  



  <I>Beispiel 2:</I>  210 Teile Milchzucker oder Rohrzucker  werden mit 40 Teilen geschmolzener Kakao  butter granuliert.



  Process for the production of base materials for suppositories which are stable at tropical temperatures. As a base for suppositories, cocoa butter or other fats are usually used, also mixed with wax, paraffin or similar substances, whereby care is taken when composing the mixture that the melting point remains below body temperature. Suppositories made from such carriers can only be kept to a limited extent. At higher temperatures, for example in the tropics, they soften, melt, lose their shape and thus become unusable.



  Attempts have already been made to produce suppositories, independent of the temperature, from soap, Glyzei-in gelatine, amines or amides and similar substances. But even suppositories made from such substances have not proven themselves in some cases, partly because the substances formed release water when stored, so that the suppositories lose their shape and become unusable, partly because substances such as glycerine or soap are added the doses in question have undesirable effects on the mucous membrane, for example laxative effects.

   For example, for suppositories already proposed basic masses of 70-75 parts of urea, 20-25% sugar and possibly cocoa butter or other additives are practically out of the question. Such masses are harmless to health, but not physiologically indifferent insofar as they have a strong dissipative effect. In addition, this laxative effect can partially or completely excrete the drug without having any effect.



  It has now been found that at tropical temperatures stable base materials for suppositories, which, as tests have shown, are free of any undesirable side effects, can be produced by solid, water-soluble, physiologically indifferent carbohydrates, such as. B. cane, grape or milk sugar, with melted fat to a pale granulated, which consists of at least 70; \ u of carbohydrates. The processing of the granulated pale to form suppositories can be done in machines like tablet machines.

   This is a major advantage of the uriplastic masses according to the invention. The previously used, mostly plastic carrier masses had to be processed into the desired end products by casting or pressing in strand form.



  As experiments have shown, suppositories made from compositions according to the invention are dimensionally stable even when they are stored for a long time at tropical temperatures, for example at 50 to 10 ° C. The soluble components dissolve in water at body temperature.



  The carrier composition according to the invention also makes pharmaceutical technology largely independent of the cocoa butter to be introduced. The invention also signifies considerable economic progress.



  <I> Example 1: </I> 210 parts of grape sugar are granulated with 40 parts of melted cocoa butter.



  <I> Example 2: </I> 210 parts of milk sugar or cane sugar are granulated with 40 parts of melted cocoa butter.
