Thermoresponsive hydrogels have gained attention because of their ability to undergo sol-gel transitions in response to physiological temperature. This unique property makes them highly suitable for sustained drug delivery, ensuring patient comfort and effective therapeutic action. The addition of bioactive compounds, such as echinacoside (ECH), further enhances the therapeutic potential of such systems. However, the low topical permeability of ECH limits its clinical use, emphasizing the need for a suitable drug delivery system (DDS). This study developed a topical thermoresponsive echinacoside-loaded hydrogel (ECH-H) using a Quality by Design approach with pectin, chitosan, and pluronic F-127 as variables. ECH-H was thoroughly characterized by FTIR, FESEM, XRD, TGA, DTA, DSC, contact angle, and rheology, and demonstrated high porosity, efficient drug entrapment and loading, hydrophilicity, bioadhesion, thermal stability, and sustained release. Biological evaluations revealed that ECH-H was hemocompatible, biodegradable, and exhibited potent anti-inflammatory, antioxidant, antimicrobial, and angiogenic activities. Furthermore, in vitro skin occlusion, release, permeation, and deposition studies confirmed prolonged drug concentration and residence time, supporting its potential as a sustained-release topical DDS. Therefore, ECH-H can be a promising formulation for future in vivo wound healing studies.
