摘要:
The present invention relates to an intraocularly injectable sterile aqueous formulation based on a mixture of hyaluronic acid and alginate, or a salt thereof, used in ophthalmology and having specific viscoelasticity, spreading, covering and ocular tissue adhesion properties and also a high capacity for neutralizing free radicals, said properties enabling said composition to strongly protect the eye tissues.
摘要:
The present invention relates generally to the treatment and/or prevention of pain associated with an intra-articular joint degeneration or disease. This invention concerns in particular a sterile and injectable aqueous formulation for administration in the intra-articular space of an intra-articular joint of a subject, in the form of a gel.
摘要:
An injectable aqueous composition of hyaluronic acid or one of the salts thereof, one or more polyol(s) and lidocaine is used for cosmetic purposes or for therapeutic purposes. It has improved viscoelastic rheological properties and long in vivo persistence. The polyol is chosen, for example, from glycerol, sorbitol, propylene glycol, mannitol, erythritol, xylitol, maltitol and lactitol. The particular properties are obtained by heat sterilizing the mixture.
摘要:
A sterile injectable aqueous formulation in the form of a gel is made up of hyaluronic acid (or one of the salts thereof) with or without other natural polysaccharide(s) and one or more polyols. The formulation is of intra-articular application in the treatment of joint degeneration, in some cases having a rheology similar to that of synovial liquid and always with an elevated resistance to degradation due to a synergistic action between the hyaluronic acid and the polyols.
摘要:
An injectable hydrogel, includes, in weight, in a physiologically acceptable carrier fluid: 0.01 to 5% of glycerol and 0.1 to 5% of cross-linked hyaluronic acid, or one of the salts thereof; characterized in that the hyaluronic acid or one of the salts thereof is cross-linked by the formation of covalent bonds using bifunctional or polyfunctional molecules, the injectable hydrogel being sterilized in moist heat and having viscoelastic properties such that Tan δ at a frequency of 1 Hz is less than or equal to 1.10. A method for producing the hydrogel, to a kit containing the hydrogel, as well as to the use thereof in dermatology are also described.

摘要:
An injectable hydrogel includes a hydrogel matrix based on (a) single-phase-type cross-linked biopolymer(s), characterized in that previously cross-linked biopolymer hydrogel particles are co-cross-linked with the matrix. A method of and a process for production of the above-mentioned hydrogel are also disclosed.
