Efficacy of a Tyrothricin-Containing Wound Gel in an Abrasive Wound Model for Superficial Wounds.
In: Skin Pharmacology and Physiology, No. 1: pp. 52-56
Background: Topical preparations are a common treatment for superficialacute wounds, which at the least do not interfere with healing andideally result in enhanced wound healing irrespective of microbialcolonization. Objective: To examine the effects of a topicalantimicrobial gel and its vehicle on the wound healing of standardized,superficial abrasions. Methods: Thirty-three healthy volunteers wereenrolled in a double-blinded, randomized, intraindividual comparisonstudy. Three standardized, superficial abrasions were induced on theirforearms. A tyrothricin 0.1% gel (Tyrosur (R) gel; EngelhardArzneimittel GmbH & Co. KG, Niederdorfelden, Germany) and its vehiclewere randomly applied to two of the test areas, and one lesion remaineduntreated. Results: A significant improvement of wound healing was seenwith both tyrothricin 0.1% gel and its corresponding vehicle in theclinical assessment. The mean area under the curve (AUC) of woundhealing scores was the same for both preparations and the meanreepithelization scores were comparable at all test points over theentire 12 days. A lower mean AUC representing less reepithelization wasfound for the untreated test fields. Conclusion: The use of tyrothricin0.1% gel and its corresponding vehicle resulted in statisticallysignificant improved wound healing with an earlier onset of healing inparticular. Based on these results obtained using an abrasive woundmodel, it can be concluded that the addition of tyrothricin 0.1% to thegel vehicle did not interfere with the improved wound healing seen withthe vehicle alone.
