CYCLODEXTRIN-GRAFTED CROSS-LINKED HYALURONIC ACID COMPLEXED WITH ACTIVE DRUG SUBSTANCES AND USES THEREOF
摘要:
A hyaluronic acid product is comprising a cross-linked hyaluronic acid and one or more cyclodextrin molecules, and further comprising a guest molecule capable of forming a guest-host complex with the aminocyclodextrin molecule acting as a host, wherein the guest molecule is a retinoid, preferably adapalene, or a RAM BA. The hyaluronic acid is cross-linked by ether bonds, and the one or more cyclodextrin molecules are grafted onto the cross-linked hyaluronic acid by amide bonds, preferably using a triazine-based coupling reagent.
