 EMI1.1 
 



  Médicament base d'héparine, administrable par voie buccale et procédé   pour sa     préparation.-   L'hépraine est un médicament bien connu et largement utilisé pour ses propritétés anti-coagulantes. Toutefois, jusqu'à ce jour, aucune forme d'administration buccale possible n'a pu en être trouvée. Cela est dû à son absence d'efficacité par voie digestive, résultant elle-même, d'une part de   l'acidité,   trop élevée du milieu gastrique, d'autre part de sa destruction en milieu intestinal par l'amylase pancréatique.

  ' "La 'présente invention a pourobjet-:ùne nouv'lie:oÍÍi1)i":':',:>, naison chimique offrant pour la première f ois la possibilité d'administrer l'héparine par'voie buccale. En outre, cette combinaison possède l'avantage de constituer un médicament retard, protégé pour n'intervenir qu'en milieu intestinal. 



   Cette combinaison est l'héparinate de protamine,   c'est-   à-dire le composé chimique résultant de la neutralisation des groupements à charge négative de l'héparine par des groupements protamine. On sait en effet qu'il n'est pas possible de donner une forme précise, ni pour l'héparine qui est un polysaccharide à poids moléculaire variable entre certaines limites, ni pour

Par contre, le caractère électro-négatif de l'héparine permet - de postuler le mécanisme de   sa.salification par     la.protamine, .   et par suite la proportion relative des deux portions que con- tient la combinaison selon l'invention. 



   Ce mécanisme permet également d'évaluer la fin de la réaction de neutralisation entre l'héparine et la protamine, bien qu'il soit encore plus commode dans la pratique, de réaliser

 EMI1.1
 



  Medicinal product based on heparin, which can be administered orally and method for its preparation. Hepraine is a medicine which is well known and widely used for its anti-coagulant properties. However, to date, no possible form of oral administration has been found. This is due to its lack of effectiveness by the digestive route, itself resulting, on the one hand, from the excessively high acidity of the gastric medium, on the other hand from its destruction in the intestinal medium by pancreatic amylase.

  The object of the present invention is: a novelty: oÍÍi1) i ": ':' ,:>, a chemical solution offering for the first time the possibility of administering heparin by the buccal route. In addition, this combination has the advantage of constituting a depot drug, protected to intervene only in the intestinal environment.



   This combination is protamine heparinate, that is to say the chemical compound resulting from the neutralization of the negatively charged groups of heparin by protamine groups. It is in fact known that it is not possible to give a precise form, neither for heparin, which is a polysaccharide of variable molecular weight between certain limits, nor for

 the protamines which: '' ¯ are natural / MM 'basic proteins' "\:' '.'" '' '' \. '' ... ''.; '.', -. '...;'. '\ f.' 'such as for example the salmine extracted from the sperms of salmon
On the other hand, the electro-negative character of heparin allows - to postulate the mechanism of sa.salification by la.protamine,. and consequently the relative proportion of the two portions contained in the combination according to the invention.



   This mechanism also makes it possible to assess the end of the neutralization reaction between heparin and protamine, although it is even more convenient in practice to achieve
