Adding lidocaine to hyaluronic acid (HA)-based gels appeared to modify their rheological properties, in the view of the first author.
This paper sought to compare the rheological properties of three CE-marked and FDA-approved gels, administered with and without lidocaine, along with two other newly FDA-approved gels.
The tested gels were as follows: NASHA® Restylane® with and without lidocaine; CPM®; Belotero® Balance with and without lidocaine; 3-D Matrix®; Surgiderm® 30XP (without lidocaine) and Juvederm® Ultra 3- Juvederm® Ultra Plus XC (with lidocaine); Preserved Network® RHA®2 (with lidocaine); Vycross® Volbella® (with lidocaine). For rheological analyses, viscoelastic data were collected with plate-plate geometry of 25mm, temperature regulated by a Peltier-effect plate, and the following assessed: Strain sweep from 0.01% to 3000% strain at 1Hz over frequency sweep from 0.1 to 100 Hz.
NASHA Restylane gels with and without lidocaine exhibited similar viscoelastic characteristics, with very similar tan δ values, but the elastic modulus G' proved significantly higher when the gel was injected with lidocaine vs without. 3D-Matrix Surgiderm 30XP gel without lidocaine and Juvéderm Ultra 3 with lidocaine exhibited similar viscoelastic characteristics, as well as tan δ values, yet the elastic modulus G' of Surgiderm 30XP proved significantly higher than that of Juvederm Ultra 3-Juvederm Ultra Plus XC. CPM Belotero Balance gels with and without lidocaine exhibited similar G' and G'' values. tan δ was somewhat higher when the gel was administered without lidocaine. VYCROSS Volbella gel exhibited a higher elastic modulus G' than the other Allergan gels, roughly nearing the NASHA gel values. Preserved Network RHA 2 gel exhibited values that were close to its partially cohesive "competitors", except for Vycross.
Adding lidocaine to HA gels does modify their rheological properties yet this, to a variable extent depending on the product. J Drugs Dermatol. 2018;17(9):948-954.
第一作者认为,在基于透明质酸(HA)的凝胶中添加利多卡因似乎会改变其流变学特性。
本文旨在比较三种获得CE标志且经美国食品药品监督管理局(FDA)批准的凝胶(分别添加和未添加利多卡因)以及另外两种新获得FDA批准的凝胶的流变学特性。
所测试的凝胶如下:含和不含利多卡因的NASHA®瑞蓝®;CPM®;含和不含利多卡因的贝洛特罗®平衡;3-D基质®;舒颜萃®30XP(不含利多卡因)和乔雅登®极致3 - 乔雅登®极致加强版XC(含利多卡因);Preserved Network®RHA®2(含利多卡因);Vycross®柔致®(含利多卡因)。对于流变学分析,使用25mm的平板几何形状收集粘弹性数据,通过珀耳帖效应板调节温度,并进行以下评估:在1Hz频率下从0.01%到3000%应变的应变扫描以及从0.1到100Hz的频率扫描。
含和不含利多卡因的NASHA瑞蓝凝胶表现出相似的粘弹性特征,损耗角正切(tan δ)值非常相似,但注射利多卡因的凝胶的弹性模量G'明显高于未注射的。不含利多卡因的3D - 基质舒颜萃30XP凝胶和含利多卡因的乔雅登极致3表现出相似的粘弹性特征以及tan δ值,但舒颜萃30XP的弹性模量G'明显高于乔雅登极致3 - 乔雅登极致加强版XC。含和不含利多卡因的CPM贝洛特罗平衡凝胶表现出相似的G'和G''值。未注射利多卡因时tan δ略高。VYCROSS柔致凝胶的弹性模量G'高于其他艾尔建公司的凝胶,大致接近NASHA凝胶的值。Preserved Network RHA 2凝胶表现出的值接近其部分具有粘性的“竞争对手”,Vycross除外。
在HA凝胶中添加利多卡因确实会改变其流变学特性,但程度因产品而异。《药物皮肤病学杂志》。2018年;17(9):948 - 954。
