Definitions
- the present invention relates to an aqueous mucoadhesive gel for local use, in particular vaginal or even rectal or intestinal. It also relates to a medicament containing this gel and possibly one or more therapeutically active substances intended (s) in particular to prevent or to treat the symptoms related to the vaginal dryness, as well as infectious pathologies of the vagina and the prevention of post-menopausal vaginal atrophies or pathologies of the rectal or intestinal mucosa. Finally, it relates to a process for preparing said gel.
- Aqueous gels based on cellulose derivatives, most often (hydroxypropyl- and methyl-cellulose), whose adhesive properties are poor, their only real action being to ensure the lubrication of the mucous membranes. These gels should be applied daily as a minimum.
- Oil-in-water emulsions containing thickening agents are more effective than previous gels and applications can be renewed only every two or three days.
- a first object of the present invention is to provide a long-lasting mucoadhesive gel for the vaginal mucosa making it possible to deliver one or more active ingredients for several days.
- a second object of the present invention is to provide a vaginal mucoadhesive gel making it possible to respect the microbial ecology of the vaginal flora by a physiological mechanism.
- a third object of the present invention is to provide a gel making it possible to offer patients the facilities of a spaced periodic application, for example every three days, which corresponds to the cycle of renewal of the epithelial cells of the vaginal mucosa.
- a fourth object of the present invention is to provide a mucoadhesive gel which, by means of an appropriate delivery system, can be applied to the rectal or intestinal mucosa.
- the aqueous gel according to the present invention comprises a natural polysaccharide having film-forming and bioadhesive properties and a mucoadhesion promoting agent.
- the aqueous gel according to the invention consists in percentage by weight:
- the gel of the present invention preferably comprises a water content greater than 80%, advantageously greater than 85%.
- polysaccharides which can be used in the context of the present invention must have good film-forming, bioadhesive and lubricating qualities required for application to the mucous membranes. They must, of course, be completely harmless to the mucous membranes and in particular respect the existing microbial balance as well as possible.
- Natural polysaccharides are divided into three categories, namely: nonionic, anionic and cationic. These polysaccharides are described in particular in the article by Georges L. Brode, Cosmetic and
- anionic polysaccharides which are suitable in the context of the present invention, there may be mentioned carrageenans or alginates.
- cationic polysaccharides suitable in the context of the present invention mention may be made of guar type polysaccharides.
- the mucoadhesion promoters are defined according to the present invention, as products which increase the adhesion capacities of a polysaccharide placed in an aqueous medium, without significantly modifying the viscosity of the initial polysaccharide gel.
- mucoadhesion promoting agents which are suitable in the context of the present invention are chosen from:
- hydrating agents suitable for the present invention one will advantageously use one of the physiologically acceptable salts of pyroglutamic acid.
- NMF Natural Moisturiser Factor
- hydrating agents such as urea, glycerin may also be suitable.
- nonionic surfactants suitable for the present invention advantageously one of the fatty acid esters of physiologically acceptable polyoxyethylene is used.
- sodium taurocholate will advantageously be used.
- EDTA EDTA will advantageously be used.
- fatty acids oleic acid, capric and caprylic acids and their physiologically acceptable salts will advantageously be used.
- adheresion promoter should be understood to mean a means which, while not significantly modifying the viscosity of the gel, increases the capacity for mucoadhesion, preferably at least 20%. Generally between 20 and 80%.
- the mucoadhesion index can be measured by performing the following test: a metal plate of 1 cm2 covered with a gel and connected to a strain gauge is applied to a mucosa. After 1 min, the separation force is measured.
- the suitable adhesion promoter for example, in the case of a carrageenan gel, in addition to sodium pyroglutamate, mention may also be made of sodium taurocholate.
- a preferred gel contains carrageenans extracted in particular from
- Rhodophytes especially of the species Gigartina or preferably Chondrus. It can be a mixture of 55 to 75% of lambda type carrageenans and 45 to 25% of carrageenans in almost equal proportion of iota and kappa type.
- the gel according to the invention contains in percentage by weight:
- the gel contains in percentage by weight:
- the balance of the compositions is practically constituted by water optionally added with pH-regulating excipients, for example, such as lactic acid and / or active ingredients as described above.
- the natural polysaccharide, water and the mucoadhesion promoter are mixed intimately, until a gel is formed, in particular in the proportions and with the characteristics described. previously.
- the mixing of the various constituents can be carried out by a process known to those skilled in the art.
- the gel can be used for the actual treatment of vaginal dryness as a medicine alone or as a vector for other active ingredients.
- the drug is intended in particular to prevent and treat infectious vaginal pathologies and to prevent and treat post-menopausal vaginal atrophy.
- active principles mention may be made of povidone iodine, econazole nitrate, estradiol.
- the gel can also be used as an excipient for the application of active ingredients for vaginal topical use, such as: hormones (estrogens for example), antifungals, antiseptics, anti-inflammatories.
- active ingredients such as: hormones (estrogens for example), antifungals, antiseptics, anti-inflammatories.
- the gel may also be used as an excipient for the application of active principles for topical rectal or intestinal use.
- the subject of the invention is therefore a medicament containing, in addition to the gel according to the invention, optionally one or more active principles, said medicament being more particularly intended for the abovementioned applications.
- the active ingredient will generally be present at 0.001% to 10% by weight.
- the gel according to the present invention has the advantage of not requiring daily application. On the contrary, it offers the possibility of an application every three days for example, which corresponds to the cycle of renewal of the epithelial cells of the mucosa.
- the product has the following properties:
- the gel according to the present invention Compared with an oil-in-water emulsion type product containing glycerin and a thickening agent (polycarbophil), the gel according to the present invention has the following advantages:
- a higher lubricating power of 30% (Method: measurement of the displacement force of a mucosal plate system),.
- a highly hydrophilic, flexible, resistant film is formed in the case of the product according to the present invention; the emulsion mentioned above does not produce anything similar.
