The invention relates to the field of gel-based delivery systems for a compound of interest, like a drug or cosmetic agent. Provided is a gel comprising at least one nonpolymeric gelator and at least one polymer, wherein the polymer content of said gel is more than 5 weight percent (wt%), preferably at least 10 wt%, more preferably at least 20 wt%. Also provided is a method for preparing the gel and the use of the gel in a controlled delivery system, for example a pH-sensitive drug delivery system.
本发明涉及以凝胶为基础的相关化合物(如药物或化妆品剂)给药系统领域。本发明提供了一种凝胶,该凝胶包含至少一种非聚合凝胶剂和至少一种聚合物,其中所述凝胶的聚合物含量超过 5 重量百分数(wt%),优选至少 10 重量百分数,更优选至少 20 重量百分数。此外,还提供了一种制备凝胶的方法,以及凝胶在控制给药系统(例如 pH 值敏感的给药系统)中的使用。
