Description
<Desc/Clms Page number 1>
Procédé pour la préparation de compositions bactériennes, enzymatiques, ou analogues, sous forme protégée contre l'altération
La présente invention a pour objet une nouvelle forme de présentation et d'administration de certaines compositions médicamenteuses présentant une sensibilité particulière à certains agents extérieurs, ainsi qu'un procédé pour la prépara- tion de cette nouvelle forme.
<Desc/Clms Page number 2>
On sait que certaines compositions telles que, en particulier, les bactéries, les levures et les enzymes, amenées à l'état sec, généralement par lyophilisation, s'altèrent rapi- dement sous l'effet de l'humidité et plus généralement de l'envi- ronnement chimique, par exemple sous l'effet de l'oxygène de l'air. On a donc recherché par quels moyens on pouvait conserver @ ces compositions pendant un temps prolongé en les soustrayant à ces agents, sans pour cela porter atteinte à leurs propriétés et en compliquer l'administration. On a bien déjà proposé d'enfer- mer ces compositions dans des enveloppes hermétiques, mais les constituants individuels de chaque dose ainsi développée demeurent non protégés contre la petite quantité d'humidité, d'oxygène ou d'autre agent d'altération enfermé avec eux.
L'invention représente donc un progrè3 par rapport à cet état de la technique, et repose sur la découverte qu'une protec- tion totale de ces compositions peut résulter da l'application d'une pellicule hydrophobe aux éléments individuels de ces compo- sitions. Une telle pellicule détermine en effet la protection de chaque constituant individuel sans l'affecter en aucune sorte de telle façon que l'inconvénient précité est écarté.
Cette pellicule peut être avantageusement une pellicule huileuse, ou de propylène-glycol , et l'on peut envisager divers modes de réalisation de l'invention, selon la nature précise de la composition à protéger et la forme d'administration envisagée.
Ainsi, pour la protection d'une composition bactérienne, telle que l'on peut en concevoir pour restaurer la microflore intestinale, on pourra utiliser une huile d'olive, tandis que pour la protection d'une composition enzymatique, par exemple contenant une lipase, qui est plus sensible à l'environnement chimique, on pourra utiliser une huile plus mitre, telle qu'une
<Desc/Clms Page number 3>
huile de parafine.
De même, pour l'administration des compositions ainsi protégées par voie orale ou externe sous forme de capsules, il sera préférable de mettre les compositions sous forme d'une pâte huileuse, chaque capsule contenant une quantité de pâte corres- pondant à une dose déterminée de la composition.
On donne ci-après quelques exemples de réalisation de l'invention

Process for the preparation of bacterial, enzymatic or similar compositions in a form protected against spoilage
The subject of the present invention is a new form of presentation and administration of certain medicinal compositions exhibiting a particular sensitivity to certain external agents, as well as a process for the preparation of this new form.
<Desc / Clms Page number 2>
It is known that certain compositions such as, in particular, bacteria, yeasts and enzymes, brought to the dry state, generally by lyophilization, deteriorate rapidly under the effect of humidity and more generally of water. the chemical environment, for example under the effect of oxygen in the air. We have therefore investigated the means by which these compositions could be preserved for a prolonged time by removing them from these agents, without thereby impairing their properties and complicating their administration. It has already been proposed to enclose these compositions in hermetic envelopes, but the individual constituents of each dose thus developed remain unprotected against the small amount of moisture, oxygen or other spoiling agent enclosed with it. them.
The invention therefore represents an advance over this state of the art, and is based on the discovery that complete protection of these compositions can result from the application of a hydrophobic film to the individual elements of these compositions. . Such a film in fact determines the protection of each individual constituent without affecting it in any way so that the aforementioned drawback is eliminated.
This film can advantageously be an oily film, or of propylene glycol, and various embodiments of the invention can be envisaged, depending on the precise nature of the composition to be protected and the form of administration envisaged.
Thus, for the protection of a bacterial composition, such as can be designed to restore the intestinal microflora, an olive oil can be used, while for the protection of an enzymatic composition, for example containing a lipase , which is more sensitive to the chemical environment, it is possible to use a more miter oil, such as
<Desc / Clms Page number 3>
paraffin oil.
Likewise, for the administration of the compositions thus protected orally or externally in the form of capsules, it will be preferable to put the compositions in the form of an oily paste, each capsule containing an amount of paste corresponding to a determined dose. of the composition.
Some embodiments of the invention are given below.
