Collagenase can promote wound healing, and its effect depends on the degradation of necrotic tissue and the collagen degradation products produced by collagenase. The possible mechanisms include accelerating re-epithelialization, promoting the formation of granulation tissue and blood vessels, and regulating inflammatory response. At present, clinical studies have shown that collagenase combined with sharp debridement or negative pressure wound therapy can significantly promote the healing of diabetic foot ulcers, and its efficacy is similar to that of hydrocolloid occlusive dressing and silver-containing wound dressings. Collagenase can promote the repair of diabetic foot ulcers, but its effect is affected by many factors, and large-sample, good design, high quality and multi-center randomized controlled trials are still needed to explore its efficacy and appropriate use conditions. This paper expounds that collagenase is one of the options in the treatment of diabetic foot ulcers from mechanism and clinical effect.
