Raepenol™ Cream, a Complex of Natural Compounds, Promotes Wound Healing and Relieves Pruritus .

Background/aim: Skin wound healing is a physiological process restoring the structural and functional integrity of injured skin. During this process, wound management preventing bacterial infection and complications is important for the regeneration of skin layers and adnexa, as well as the protective function of the skin. Therefore, the development of an effective ointment to promote wound healing without complications is beneficial.

Materials And Methods: This study developed Raepenol™ cream, comprising a base cream and natural compounds including paeonol, D-panthenol and extract of Centella asiatica, and assessed its therapeutic effect in wound healing. A rat model of skin wound healing and a mouse model of imiquimod-induced pruritus were employed. The effect of Raepenol™ cream was evaluated by wound size and histological analysis, including the integrity of skin structures and inflammatory response.

Results: Raepenol™ cream treatment effectively restored the structural integrity of the skin in rats, including wound closure, regeneration of skin adnexa, and reconstitution of collagen, comparable to commercial ointment. Additionally, Raepenol™ cream significantly suppressed pruritus by inhibiting mast cell infiltration or retention in the inflammatory site of mouse ears.

Conclusion: Raepenol™ cream effectively promoted wound healing and relieved pruritus in animal models. These results suggest that it could be a promising option for wound care and pruritus relief, offering potential advantages over current ointments.
