- the present invention relates to a trans ⁇ dermal matrix system, for administration of ibuprofen, comprising a support and a self-adhesive matrix based on acrylate copolymers, said matrix containing ibuprofen and diethyl phthalate in order to obtain stable formulations over time.
- the invention also relates to a method for preparing said system.
- Ibuprofen which has the following systematic nomenclature: ⁇ -methyl-4- (2-methylpropyl) benzene-acetic acid, and the developed formula:
- phthalic acid derivatives are commonly used as plasticizers for acrylate copolymers as described for example in EP-A-0 435 199 and EP-A-0 531 938, nothing is indicated on their role or their capacity to stabilize an active principle within an acrylic matrix and in particular nothing is disclosed on the role of diethyl phthalate as stabilizer of an acrylic formulation containing ibuprofen according to the present invention. Aims of the invention
- Transdermal systems which, like the gels and creams commonly used today have the advantage of acting only on the part to be treated and of avoiding the risks associated with the use of these compounds by the oral route, do not do not have the drawbacks of said gels and creams. They do not require repeated application of the product several times a day. There is no need to spread the dose to be applied on the surface to be treated and problems of clothing deterioration with the cream or gel are avoided. Generally, their duration of action can be several days; and, thanks to their good adhesion, they can even be used underwater and there is no loss or decrease in activity when taking a shower or when swimming.
- the aforementioned aims are achieved thanks to a new technical solution according to which we add to the matrix system which contains copolymers based on acrylates or methacrylates and ibuprofen in the form of free acid, a compound which makes it possible to obtain formulas stable.
- the compound recommended according to the invention is diethyl phthalate.
- a self-adhesive transdermal matrix system for the percutaneous administration of ibuprofen is recommended, said matrix system, which comprises a support and a self-adhesive matrix, being characterized in that said matrix comprises:
- a method for the preparation of said transdermal matrix system, said method being characterized in that it comprises the steps consisting in: ( ⁇ ) dissolving, with stirring in an organic solvent, the cationic acrylate copolymer, which has a glass transition temperature between 20 and 80 ° C, ibuprofen and diethyl phthalate, and homogenize the resulting mixture;
- FIGS. 1 and 2 represent the amount (Q, expressed as a percentage) of ibuprofen, present in the transdermal system, as a function of time (t, expressed in months). More precisely, in these drawings FIG. 1 makes it possible to compare curves 1 (product Ex 1) and A (product CP 2) relating to the amount of ibuprofen that is found in the matrix system tested when said transdermal system is maintained at a temperature of 23 ° C; FIG. 2 makes it possible to compare curves 1 (product Ex 1), A (product CP 2) and B (product CP 5) relating to the amount of ibuprofen that is found in the matrix system tested when one hands ⁇ keeps said transdermal system at a temperature of 40 ° C.

- an amount of ibuprofen will be used in the matrix, in proportions of 5 to 15 parts by weight.
- an amount of ibuprofen of the order of 10 parts by weight will be used per 100 parts by total weight of the matrix.
- diethyl phthalate promotes the release of ibuprofen by its action at the macromolecular network of the matrix.
- this phthalic acid derivative also makes it possible to minimize the problems of pain or skin irritation during the removal of the transdermal system containing adhesives such as acrylate copolymers. This is a non-negligible advantage in the case of a treatment which requires the successive placement of several devices on an already painful part to be treated.
- adhesive acrylate copolymer having a glass transition temperature (Tg) of between -70 and -10 ° C is meant here synthetic resins of adhesive acrylates, self-crosslinkable or not.
- hydroxyalkyl esters of acrylic or methacrylic acids in which the alkyl group contains 2 to 4 carbon atoms in particular 2-hydroxyethyl acrylate, 2-hydroxyethyl methacrylate, 2-hydroxypropyl acrylate and methacrylate
- these copolymers can be cross-linking, they also optionally contain a crosslinking agent chosen from those generally used by those skilled in the art, such as, for example, organic peroxides, polyisocyanates, metal chelates, such as titanium or aluminum or metallic acetylacetonates, in particular zinc, magnesium, aluminum, etc.

- EXAMPLE 1 1761 g of acetone and 300 g of EUDRAGIT®100 (cationic copolymer, consisting of dimethylaminoethyl methacrylate and neutral ester of methacrylic acid, marketed by the company ROHM PHARMA and having a glass transition temperature of 50 ° C) and stirred at room temperature for at least 40 minutes. 300 g of ibuprofen and 600 g of diethyl phthalate are then introduced, still with stirring, until a homogeneous mixture is obtained.
- EUDRAGIT®100 cationic copolymer, consisting of dimethylaminoethyl methacrylate and neutral ester of methacrylic acid, marketed by the company ROHM PHARMA and having a glass transition temperature of 50 ° C
- the mixture thus obtained is coated on a silicone polyester support at the rate of (100 ⁇ 10) g / nr. 2. It is dried at a temperature progressively increasing from 40 to 80 ° C. in order to evaporate the solvents and thus allow the crosslinking of the acrylic adhesive. The matrix thus obtained is then transferred onto a polyethylene / ethylene / vinyl acetate support. The products are cut to the desired size and packaged in heat-sealable bags.
- Example 3 The coating is carried out at a rate of (100 ⁇ 10) g / m2 and the matrix obtained is transferred to a polyethylene support.
- Example 3 The coating is carried out at a rate of (100 ⁇ 10) g / m2 and the matrix obtained is transferred to a polyethylene support.
- Example 2 The procedure is analogous to Example 1 by transferring the matrix obtained onto a polyethylene support. Comparative example CP 1 2389.9 g of solution are introduced into a mixer.
- matrix systems were monitored over time at a temperature of 23 ° C. and at a temperature of 40 ° C. Measurements of the amount of ibu- profene present in the devices after manufacture and then after 1, 2, 3, 4, 6, and 9 months.
- the quantity of ibuprofen recovered is determined by high performance liquid chromatography (HPLC).
- HPLC high performance liquid chromatography
- the comparative examples CP 3 to CP 6 which respectively contain 2-octyldodecyl myristate, LAUROGLYCOL® or mixtures of 18% and 10% of LAUROGLYCOL® and lauric alcohol, associated with a mixture of 2 acrylate copolymers having different glass transition temperatures, all give, at 40 ° C, from the sixth month more than 8% loss in ibuprofen, and in the ninth month between about 13% (ie 13.5% for CP 3) and 28% (ie 22.5% for CP 5) of ibuprofen loss.
- the formulations containing diethyl phthalate give stable or acceptable systems.
- Example 2 which contains 18% of diethyl phthalate, exhibits an acceptable loss at 6 and 9 months and at 40 ° C. At 9 months we still find 9.21% of ibuprofen present (compared to the initial content of 9.79%), or only 5.9% of loss.
- the losses are always less than 3% after 6 and 9 months.
- the losses are always less than 3% after 6 and 9 months.
- the losses are always less than 3% after 6 and 9 months.
- the losses are always less than 3% after 6 and 9 months.
