Definitions
- the invention relates to the field of biodegradable gels and hydrogels used as biomaterials and more particularly in the medical and aesthetic fields.
- Examples of medical applications include injections to replace the defective biological fluids for example in the joints to replace the synovial fluid, the injection following surgery to prevent peritoneal adhesions, periurethral injections to treat the incontinence and injections following surgery for presbyopia.
- aesthetic applications include, for example, injections for filling wrinkles, fine lines and skin defects or increasing volumes such as lips, cheekbones, etc..
- the application WO 2013/186493 discloses hyaluronic acid compositions including a sucrose octasulfate and the application WO 2014/032804 discloses hyaluronic acid compositions including a derivative of vitamin C.
- compositions based on hyaluronic acid and comprising lidocaine relate to compositions based on hyaluronic acid and comprising lidocaine.
- Example 1 of this application relates to a composition based on hyaluronic acid of the "hylagel” type (BIOMATRIX), and containing lidocaine.
- lidocaine a number of products based on hyaluronic acid comprising lidocaine are marketed, for example JUVEDERM®, RESTYLANE®, EMERVEL LIDOCA ⁇ NE®, TEOSYAL SENSE®, etc.
- lidocaine anesthetics that lidocaine are also used, for example, a patent application EP 2 581 079 in the name of BIOPOLYMER describes compositions based on hyaluronic acid and prilocaine, having a profile of rapid release of the prilocaine. In the application WO 2015/015407 in the name of TEOXANE, compositions based on uncrosslinked and partially crosslinked hyaluronic acid comprising mepivacaine or lidocaine are disclosed.
- Local anesthetics are sometimes used in combination with polyols.
- lidocaine is added to a number of compositions based on crosslinked hyaluronic acid. Whatever the composition of hyaluronic acid, the addition of lidocaine does not have the effect of improving the rheological properties during heat sterilization, without having a degradation effect of these said rheological properties.
- the prior art discloses that the addition of exemplary polyol (s) has the effect of limiting the degradation of the rheological properties of a composition based on hyaluronic acid during the heat sterilization.
- the antioxidant properties of the polyols allow for better in vivo remanence, and these properties confer a number of advantages to the compositions.
- polyols are beneficial in vivo.
- their anti-oxidant and anti-free radical effects are particularly beneficial, in particular for cells and DNA sequences.
- they improve the remanence of the gels in vivo, so there is a need for compositions comprising polyols.
- compositions based on hyaluronic acid having all the properties related to the addition of at least one polyol, while allowing to adapt their rheological properties to the specifications of the injectable products, during sterilization by heat, especially by moist heat.
- the Applicant has shown that the incorporation of at least one local anesthetic selected from the group consisting of benzocaine, chloroprocaine, procaine, etidocaine, aptocaine, chlorobutanol, diamocaine , dyclonine, guafecainol, polidocanol, articaine, bupivacaine, ropivacaine, tetracaine, pramocaine and their salts and their isolated isomers, with a sterilized aqueous composition based on hyaluronic acid already comprising at least one polyol had the effect of allowing the adaptation of the rheological properties of the composition during sterilization, that is to say the reduction of the elastic modulus G ', the viscous modulus G "and / or the viscosity ⁇ .
- the local anesthetic may be chosen from the family of amino-amides consisting of etidocaine, aptocaine, articaine, bupivacaine, ropivacaine and their salts and their isolated isomers.
- the local anesthetic may be selected from the family of amino-esters consisting of benzocaine, chloroprocaine, procaine, tetracaine and their salts and their isolated isomers. In one embodiment, the local anesthetic may be chosen from the family of amino-ethers consisting of diamocaine, guafecainol, pramocaine and their salts and their isolated isomers.
- compositions based on hyaluronic acid This is particularly advantageous in the field of injectable compositions based on hyaluronic acid. Indeed, this makes it possible to obtain compositions whose rheological properties are close to those of the surrounding tissues.
- injectability is the faculty of an injectable composition to be injected. Most of the time, the injectability is expressed in Newton (N) to inject with a needle of 27G1 / 2 with a piston speed of 13 mm / minute. A good injectability results in a weak force (N), and conversely, the greater the force (N) is important, the less the injectability is easy. Injectability can also be called “extrusion force”.
- the sterilized aqueous injectable composition according to the invention is characterized in that the at least one local anesthetic of the amino-amide family is selected from the group consisting of etidocaine, aptocaine, articaine, bupivacaine, ropivacaine and their isolated salts and isomers.
- the sterilized aqueous injectable composition according to the invention is characterized in that the at least one local anesthetic is selected from the group consisting of benzocaine, chloroprocaine, procaine, etidocaine, aptocaine, diamocaine, dyclonine, guafecainol, articaine, bupivacaine, ropivacaine, tetracaine and their isolated salts and isomers.
- the sterilized aqueous injectable composition according to the invention is characterized in that the at least one local anesthetic is benzocaine.
- the sterilized aqueous injectable composition according to the invention is characterized in that the at least one local anesthetic is chloroprocaine.
