Definitions
- Patent FR 2682296 proposes a non-chemical method of preserving cosmetic or dermopharmaceutical products which is based on the use of gels of the glycerol poly (meth) acrylate type, the property of which has a strong osmotic effect on its environment, which inactivates the microorganisms introduced into a cosmetic preparation by depriving them of water.
- Patent application 9509512 of August 4, 1995 proposed improving the efficiency of the method by combining polyols and a fluidizing agent with poly (meth) acrylate gel.
- the discovery object of this patent is that these gels have antimicrobial, moisturizing, healing, anti-inflammatory properties such that their pharmaceutical use in very diverse fields is particularly advantageous, especially since these gels are non-toxic, not - irritating, colorless and odorless, soluble and miscible in water, pleasant to the touch and economical.
- the glyceryl poly (methacrylate) gel is obtained by mixing water, glycerin, in a polyacrylic or polymethacrylic acid polymer in selected proportions (approximately 30-50% water, 30-60% glycerin and 0.1 to 5% of polymer) according to a particular manufacturing process which gives the gel physical activity (osmotic power and water absorption capacity). This physical activity is the important key of the compositions for carrying out the invention.
- This chlatrate gel is characterized by its strong water retention power. It does not dry, even exposed for months to ambient air or subjected to a vacuum for 48 hours. This property is essential, conventional hydrogels, alginate, polysaccharide, cellulose or its derivatives or silicate gels do not meet this criterion. This gel is particularly effective in inactivating the microorganisms with which it comes into contact, depriving the germs, by its osmotic effect, of the water they need to survive.
- the gel is also characterized by its viscosity (50,000-2,000,000 centipoises; nevertheless with a non-Newtonian rheological behavior).
- the polymer is preferably chosen from sodium, potassium, triethylamine, triethanolamine, ammoniacal salts of acrylic acid and / or methacrylic acid, but also from the esters or amides of these acid polymers, or the crosslinked derivatives of carbomer type
- crosslinking with allyl ethers of pentaerythritol, sucrose or propylene, for example crosslinking with allyl ethers of pentaerythritol, sucrose or propylene, for example.
- the polyol contained in the base gel is preferably glycerin, to which other polyols can be mixed in variable proportion: alkane-diols and their monoethers, polyalkylglycols, various sugars.
- gels can then be used either in pure form or in diluted form, or incorporated into other gels or other dosage forms.
- Example 1 Pure gel% (w / w)
- the base vehicle can be prepared from the substances usually used to make hydrogels acceptable in the food industry or for topical application (carrageenans, xanthan gums and other polysaccharides, polyacrylates or polymethacrylates and their crosslinked derivatives such as carbomers, sodium aluminum silicates etc.). Examples of pharmaceutical applications of these gels:
- Example No. 1 The gel of Example No. 1 was tested for its anti-edema activity.
- the protocol used is classic: creation of an abscess by injection of carrageenan.
- Anti-HIV activity of the gel of Example 5 This test is performed according to WHO recommendations.
- the VI H virus is fixed on a plate using polylysine.
- the product to be tested is then added.
- cells sensitive to infection with VI H are added: if the cells are infected, the product has not been virucidal, otherwise, the virucidal effect of the product is manifest.
- the effectiveness of the gel of Example No. 5 was tested at different concentrations: 40%, 30%, 20% and 10% in water (w / w).
- the contact time has been set at 5 ', 15' and 60 '.
- Example No. 9 Inactivation of the germs responsible for STDs:
- Example No. 4 inactivates the chlamydia trachomatis germs in 5 minutes at a concentration of 30%, and in 15 minutes at a concentration of 10%.
- Example 10 Safety of the gel: the gels of Examples 1 and 5 were tested for their irritant power: the indices of primary skin irritation, primary ocular irritation and vaginal tolerance (observational study clinical and histological) show a total absence of irritant power. Oral toxicity is also zero:> 5000 mg / kg. These examples are not limitative. Those skilled in the art can formulate products according to the needs of the application by incorporating the glyceryl poly (meth) acrylate type gel in any suitable dosage form.
- Possible applications of these gels include: preventing HIV infection by vaginal application and / or lubrication of condoms; treatment of herpes symptoms (inactivation of the virus in active and / or inactive phase); prevention of infection with germs responsible for sexually transmitted diseases (gonorrhea, syphylis, chlamydias), treatment of pre- or post-menopausal vaginal dryness; prevention and treatment of pressure sores: the hydrating and antimicrobial power ensures a lively and healthy skin.
- the glyceryl poly (meth) acrylate gels which are the subject of this patent can be used in any galenic form used in pharmacy for local application on the skin, mucous membranes, cavities and orifices of the body: aqueous solutions, O / W and W / O emulsions. , milks, lotions, gels, ointments, soaps, sticks, sprays, poultices, dressings, without this list being exhaustive.
- the concentration of use of these glyceryl poly (meth) acrylate type gels which are the subject of this patent can vary between 1 and 100% (w / w) depending on the application.
- a particularly interesting embodiment of the invention is the gel which is composed of glycerin (40-70% w / w), water (10-50% w / w), 1, 2-octanediol (0.1 to 10% w / w), polyethylene glycol (1 to 30% w / w) and neutralized polyacrylate or polymethacrylate (0.1 to 5%).
- glyceryl poly (meth) acrylate type gels which are the subject of this patent can be combined in pharmaceutical compositions with any other ingredient usually used in this field: extraction and / or synthetic lipids, gelling and viscosifying polymers, surfactants and emulsifiers, hydro- or liposoluble active ingredients, plant extracts, tissue extracts, marine extracts, polyols, softeners, anti-microbial agents ...
- compositions containing the gels of the glyceryl poly (meth) acrylate type which are the subject of this patent can therefore be intended for the treatment and prevention of HIV infection, symptoms of herpes, sexually transmitted diseases, pre-vaginal dryness. - or post-menopause, bedsores, insect bites, light burns, post-radiotherapy burns, varicose ulcers, vaginal candidiasis, hemorrhoids.
