Subcutaneous Dexpanthenol Administration and Wound Epithelialization (DEXPAN-WOUND)

April 16, 2026 updated by: Dilara CANBAY OZDEMIR

Evaluation of the Effect of Subcutaneous Dexpanthenol Administration on Wound Epithelialization: A Pilot Randomized Controlled Study

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.

Study Overview

Detailed 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.

Experimental: Intervention Group
Participants in this group will receive standard wound care plus perilesional subcutaneous dexpanthenol injections administered at predefined intervals according to a standardized protocol.
Dexpanthenol will be administered by perilesional subcutaneous injection around the wound area in addition to standard wound care. The injection dose and volume will be standardized according to wound size, with a limited number of treatment sessions.
Standard wound care includes wound cleansing with saline solution and topical wound management according to institutional protocols.
Active Comparator: Control Group
Participants in this group will receive standardized wound care alone without subcutaneous dexpanthenol administration.
Standard wound care includes wound cleansing with saline solution and topical wound management according to institutional protocols.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage Change in Wound Area
Time Frame: Baseline (Day 0) to Day 19 ±1 and Day 26 ±1
The primary outcome measure is the percentage change in wound area from baseline. Wound area will be calculated using standardized ruler-based measurements of the longest length and widest width of the wound and applying an elliptical area formula. The percentage change in wound area will be calculated by comparing baseline measurements with follow-up measurements.
Baseline (Day 0) to Day 19 ±1 and Day 26 ±1

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Wound Epithelialization Percentage
Time Frame: Baseline (Day 0) to Day 19 ±1 and Day 26 ±1
Wound epithelialization will be assessed as the percentage of epithelial tissue covering the wound surface. Changes in epithelialization percentage over time will be evaluated using standardized wound bed tissue composition assessments.
Baseline (Day 0) to Day 19 ±1 and Day 26 ±1
Time to Complete Epithelialization
Time Frame: Up to approximately 26 days
Time to complete epithelialization will be defined as the number of days from baseline to the first visit at which the wound shows complete epithelial coverage without drainage, confirmed at two consecutive follow-up visits.
Up to approximately 26 days
Wound Bed Tissue Composition
Time Frame: Baseline (Day 0) to Day 26 ±1
Wound bed tissue composition, including percentages of epithelial tissue, granulation tissue, and fibrin or necrotic tissue, will be assessed at each study visit using standardized clinical evaluation methods.
Baseline (Day 0) to Day 26 ±1
Local Injection Site Reactions and Adverse Events
Time Frame: Baseline (Day 0) to Day 26 ±1
Safety outcomes will include the assessment of local injection site reactions such as pain, erythema, edema, induration, and nodule formation, as well as the occurrence of any other adverse events recorded throughout the study period.
