Objectives: This study aims to compare the therapeutic effects of acyclovir nanofiber and acyclovir-clobetasol nanofiber formulations with their non-nano formulations (cream formulation) on recurrent labial herpes.
Materials and methods: Eighty patients with labial herpes lesions were divided into four groups, each receiving one of the following treatments: acyclovir-clobetasol nano patch, acyclovir-clobetasol cream, acyclovir nano patch, or acyclovir cream. Pain levels and recovery times were assessed. The Wilcoxon test compared pain levels, while the log-rank test compared healing and scabbing times.
Results: Acyclovir-clobetasol nanofiber and cream, along with acyclovir nanofiber, significantly reduced symptoms compared to the acyclovir cream. The recovery and scabbing times were shorter in patients who received acyclovir-clobetasol formulations compared to those receiving acyclovir alone.
Conclusion: Acyclovir-clobetasol combinations accelerated recovery times compared to acyclovir alone. Additionally, nanofiber formulations demonstrated enhanced healing efficacy over cream formulations.
