About
Chronic wounds are wounds that do not heal properly over time and can significantly reduce quality of life. Common types include diabetic foot ulcers, venous leg ulcers, and arterial ulcers. Improving wound healing and speeding up skin regeneration (epithelialization) are important goals in the care of these patients.
Dexpanthenol is a vitamin B5 derivative that supports skin repair and tissue regeneration. It is widely used in topical treatments, and injectable forms are approved for clinical use. However, the effects of subcutaneous (under the skin) dexpanthenol injections on chronic wound healing have not been sufficiently studied in clinical settings.
The purpose of this study is to evaluate whether adding subcutaneous dexpanthenol injections to standard wound care improves wound healing compared with standard wound care alone. Adult patients with non-infected chronic wounds will be randomly assigned to one of two groups. One group will receive standard wound care only, while the other group will receive standard wound care plus subcutaneous dexpanthenol injections around the wound area.
Wound healing will be assessed by measuring changes in wound size and the degree of skin epithelialization over time using standardized and objective methods. Safety will be monitored by recording local reactions at the injection site and any other adverse events during the study.
The results of this study may provide preliminary clinical evidence on the effectiveness and safety of subcutaneous dexpanthenol as an additional treatment option for chronic wound management.
Full description
Chronic wounds, including diabetic foot ulcers, venous leg ulcers, and arterial ulcers, represent a major clinical challenge due to delayed healing, increased risk of complications, and reduced quality of life. Impaired epithelialization, prolonged inflammation, and insufficient tissue regeneration are key mechanisms contributing to non-healing wounds. Therefore, interventions that support epithelial repair and wound closure may improve clinical outcomes when added to standard wound care.
Dexpanthenol, a provitamin B5 derivative, is converted to pantothenic acid and plays an essential role in coenzyme A metabolism, which is involved in cellular energy production and tissue repair. Experimental and clinical studies have suggested that dexpanthenol may enhance fibroblast activity, epithelialization, and skin barrier restoration. Injectable formulations of dexpanthenol are approved for clinical use; however, data on subcutaneous administration for chronic wound healing are limited.
This study is designed as a randomized, open-label, controlled clinical trial to evaluate the effect of subcutaneous dexpanthenol administration on wound epithelialization when added to standard wound care. Adult patients with non-infected chronic wounds, including diabetic foot ulcers, venous leg ulcers, and arterial ulcers, will be enrolled. Eligible participants will be randomly assigned in a 1:1 ratio to either the intervention group or the control group using computer-generated block randomization.
Participants in the intervention group will receive standard wound care plus perilesional subcutaneous dexpanthenol injections administered at predefined intervals. The dose and injection volume will be standardized according to wound size, and a limited number of treatment sessions will be applied. Participants in the control group will receive standardized wound care alone. Both groups will follow the same visit schedule and assessment procedures throughout the study period.
Wound healing will be evaluated using objective and standardized methods. The primary outcome is the percentage change in wound area from baseline to follow-up visits. Secondary outcomes include changes in epithelialization percentage, time to complete epithelialization, wound bed tissue composition, and safety outcomes. Safety assessments will focus on local injection-site reactions and the occurrence of any adverse events, which will be systematically recorded during each visit.
This study aims to provide structured clinical data on the feasibility, safety, and potential clinical benefit of subcutaneous dexpanthenol as an adjunctive treatment in chronic wound management. The findings are expected to contribute to future studies and inform the design of larger-scale clinical trials in this field.
