    • The invention relates to a biocompatible polymer having general formula (I) AaXxYy, wherein: A denotes a monomer; X denotes an RCOOR′ group; Y denotes an O or N-sulphonate group which is fixed to A and which has either formula —ROS03R′ or —RNS03R′ in which R denotes an optionally branched and/or unsaturated aliphatic hydrocarbon chain which can contain one or more aromatic rings and R′ denotes a hydrogen atom or a cation; a denotes the number of monomers; x denotes the rate of substitution of the A monomers by the X groups; and y denotes the rate of substitution of the A monomers by the Y groups. More specifically, the invention relates to the use of said biocompatible polymers for the preparation of a pharmaceutical, dermatological or cosmetic composition or a medical device, which are intended to prevent, relieve and/or treat discomfort, distress, itches, irritations and/or pain and/or to protect tissues against same. In addition, in certain cases, the use of said biocompatible polymers for pain treatment can impact on the actual curing of certain diseases. Significant improvements and even cures have been observed in relation to chronic and painful diseases that are associated with alterations in the extracellular matrix regardless of the origin thereof.
    • 本发明涉及具有通式(I)A a X x Y y的生物相容性聚合物,其中:A表示单体; X表示RCOOR'基团; Y表示固定在A上并具有式-ROS03R'或-RNS03R'的O或N-磺酸盐基团,其中R表示可含有一个或多个芳环的任选支链和/或不饱和脂族烃链,R '表示氢原子或阳离子; a表示单体数目; x表示X单体的A单体的取代率; y表示Y单体由Y基取代的比例。 更具体地,本发明涉及所述生物相容性聚合物用于制备药物,皮肤病学或化妆品组合物或医疗装置的用途,其旨在防止,缓解和/或治疗不适,痛苦,瘙痒,刺激和/或 疼痛和/或保护组织免受同样的影响。 此外,在某些情况下,使用所述生物相容性聚合物进行疼痛治疗可能会影响某些疾病的实际固化。 对于与细胞外基质的改变相关的慢性和疼痛性疾病,观察到显着的改善甚至治愈,不管其来源如何。
