Abstract
Description
La présente invention concerne généralement une nouvelle association pharmaceutique trouvant application dans le traitement de l'acné. The present invention generally relates to a novel pharmaceutical combination having application in the treatment of acne.
On sait que la pathogénie de l'acné associe plusieurs facteurs,<B>à</B> savoir<B>:</B> <B>-</B> l'hypersécrétion séborrhéique, sous la dépendance des androgènes <B>-</B> la rétention du sébum, par anomalie de la kératinisation du follicule pilo-sébacé, conduisant<B>à</B> la formation de comédons<B>;</B> et <B>-</B> la réaction inflammatoire induite par des germes saprophytes et par certains composants irritants du sébum. The pathogenesis of acne is known to associate several factors, <B> to <B>: <B> - </ B> seborrheic hypersecretion, under the control of androgens <B > - </ B> sebum retention, by keratinization anomaly of the pilosebaceous follicle, leading <B> to </ B> formation of comedones <B>; </ B> and <B> - </ B> the inflammatory reaction induced by saprophytic germs and certain irritating sebum components.
L'érythromycine est un agent antibiotique actif sur les germes saprophytes de la peau qui s'oppose<B>à</B> la colonisation bactérienne du follicule pilo- sébacé et<B>à</B> la réaction inflammatoire de l'acné. Erythromycin is an active antibiotic agent on saprophytic skin cells that opposes bacterial colonization of the pilosebaceous follicle and <B> to </ B> the inflammatory reaction of the acne.
De ce fait, l'érythromycine est largement utilisée dans le traitement de l'acné par exemple sous forme de solution alcoolique pour application locale dosée<B>à</B> 4<B>%.</B> As a result, erythromycin is widely used in the treatment of acne, for example in the form of an alcoholic solution for topical application of <B> to </ B> 4 <B>%. </ B>
Cependant, l'utilisation de l'érythromycine peut, dans certains cas, induire des résistances bactériennes de fréquence croissante. However, the use of erythromycin may, in some cases, induce bacterial resistance of increasing frequency.
Il a été découvert, et ceci constitue le fondement de la présente invention, que l'association de Pérythromycine et d'un acide dicarboxylique ayant de<B>7 à 13</B> atomes de carbone, et en particulier l'acide azélaïque, présente un profil pharmacologique intéressant qui la rend particulièrement utile dans le traitement de l'acné. It has been discovered, and this constitutes the foundation of the present invention, that the combination of erythromycin and a dicarboxylic acid having from <B> 7 to 13 </ B> carbon atoms, and in particular azelaic acid , has an interesting pharmacological profile that makes it particularly useful in the treatment of acne.
Ainsi, il a été observé que dans cette nouvelle association l'acide dicarboxylique précité évite l'induction de résistance bactérienne en optimisant, par voie de conséquence, l'action antibiotique de l'érythromycine. Thus, it has been observed that in this new combination the above-mentioned dicarboxylic acid avoids the induction of bacterial resistance by optimizing, consequently, the antibiotic action of erythromycin.
En outre, il a été constaté que l'association précitée limite le risque de récidive de l'acné, en prévenant, de façon permanente tout au long du traitement, le flux hyperséborrhéique qui constitue le terrain indispensable<B>à</B> l'apparition des manifestations acnéïques. Sous cet aspect, l'utilisation simultané de Vérythrornycine et d'un acide dicarboxylique ayant de<B>7 à 13</B> atonies de carbone conduit<B>à</B> un effet global qui ne pourrait être obtenu par des applications séparées de ces deux principes actifs. In addition, it has been found that the aforementioned combination limits the risk of recurrence of acne, by preventing, permanently throughout the treatment, the hyperseborrheic flow which constitutes the indispensable ground <B> to </ B> the appearance of acneic manifestations. In this respect, the simultaneous use of Vérythrornycin and a dicarboxylic acid having <B> 7 to 13 </ B> carbon atony results in an overall effect that can not be achieved by separate applications of these two active ingredients.
Dans le cadre de la présente description, l'expression "acide dicarboxylique ayant<B>7 à 13</B> atomes de carbone" vise<B>à</B> couvrir les acides eux- mêmes, mais également leurs sels ou leurs dérivés solubles dans le milieu utilisé pour réaliser la composition pharmaceutique. In the context of the present description, the expression "dicarboxylic acid having <B> 7 to 13 </ B> carbon atoms" is intended <B> to </ B> cover the acids themselves, but also their salts or their soluble derivatives in the medium used to make the pharmaceutical composition.
Parmi ces acides dicarboxyliques, l'acide actuellement préféré est l'acide azélaîque, qui peut s'utiliser soit sous forme d'acide, soit sous forme d'un sel comme notamment le sel d'ammonium, ou le sel de sodium. Among these dicarboxylic acids, the currently preferred acid is azelaic acid, which can be used either in acid form, or in the form of a salt such as in particular the ammonium salt, or the sodium salt.
D'autres acides dicarboxyliques, comme par exemple l'acide pimélique ou l'acide sébacique peuvent également être cités dans le cadre de la présente invention. Other dicarboxylic acids, such as, for example, pimelic acid or sebacic acid may also be mentioned in the context of the present invention.
Avantageusement, l'association pharmaceutique conforme<B>à</B> la présente invention se présentera sous une forme appropriée pour une administration locale par voie topique, comme par exemple sous forme de solution, de gel, de crème ou de pommade. Advantageously, the pharmaceutical combination according to the present invention will be in a form suitable for topical topical administration, such as, for example, as a solution, gel, cream or ointment.
Avantageusement, cette composition se présentera sous la forme d'une solution pour application locale comprenant de 2<B>à 6 %</B> d'érythromycine base et de <B>5 à</B> 20<B>%</B> d'acide dicarboxylique ayant de<B>7 à 13</B> atomes de carbone. Advantageously, this composition will be in the form of a solution for local application comprising from 2 <B> to 6% </ B> of erythromycin base and from <B> 5 to </ B> 20 <B>% < Dicarboxylic acid having <B> 7 to 13 </ B> carbon atoms.
Cette composition peut avantageusement comporter des additifs habituels permettant de faciliter l'acheminement des principes actifs notamment au niveau du follicule sébacé. This composition may advantageously include usual additives to facilitate the delivery of active ingredients including the sebaceous follicle.
Une telle composition peut être préparée selon des méthodes connues en soi, notamment en incorporant le principe actif constitué par l'association précitée<B>à</B> des excipients habituellement utilisés, tels que par exemple l'alcool éthylique<B>à 96 %,</B> dans le cas d'une solution. Such a composition may be prepared according to methods known per se, in particular by incorporating the active ingredient constituted by the aforementioned association <B> into </ B> of the excipients usually used, such as, for example, ethyl alcohol <B> to 96%, </ B> in the case of a solution.
La dose journalière utilisable d'érythromycine et d'acide dicarboxylique ayant de<B>7 à 13</B> atomes de carbone dépendra, bien entendu, de l'état du patient<B>à</B> traiter. The usable daily dose of erythromycin and dicarboxylic acid having <B> 7 to 13 </ B> carbon atoms will, of course, depend on the condition of the patient <B> to </ B> to be treated.
Par ailleurs, le rapport pondéral de l'érythromycine <B>à</B> l'acide dicarboxylique ayant de<B>7 à 13</B> atomes de carbone sera généralement compris entre environ<B>1:3</B> et environ<B>1:5</B> et sera de préférence de<B>1:5.</B> On the other hand, the weight ratio of erythromycin <B> to </ B> dicarboxylic acid having <B> 7 to 13 </ B> carbon atoms will generally be between about <B> 1: 3 </ B> and about <B> 1: 5 </ B> and will preferably be <B> 1: 5. </ B>
Selon un mode de réalisation actuellement préféré, une composition pharmaceutique selon l'invention se présentera sous forme d'une solution alcoolique comprenant 4<B>%</B> d'érythromycine base et 20<B>%</B> d'acide azélaïque. According to a presently preferred embodiment, a pharmaceutical composition according to the invention will be in the form of an alcoholic solution comprising 4% of erythromycin base and 20% of erythromycin base. azelaic acid.
Une telle solution pourra être appliquée de façon quotidienne une<B>à</B> deux fois après lavage soigneux du visage avec un savon den-natologique et séchage, pendant une durée moyenne de<B>1 à 3</B> mois. Such a solution can be applied daily <B> to </ B> twice after careful face wash with den-natological soap and drying, for an average duration of <B> 1 to 3 </ B> months .
La présente invention couvre encore un procédé de traitement thérapeutique de l'acné, caractérisé en ce qu'il consiste<B>à</B> appliquer de façon topique une quantité thérapeutiquement efficace d'une association d'érythromycine et d'un acide dicarboxylique ayant<B>7 à 13</B> atomes de carbone et en particulier l'acide azélaïque telle que définie précédemment. The present invention further provides a method of therapeutic treatment of acne, characterized in that it consists of topically applying a therapeutically effective amount of a combination of erythromycin and an acid. dicarboxylic acid having <B> 7 to 13 </ B> carbon atoms and in particular azelaic acid as defined above.
