BACKGROUND: Cryotherapy using Wartner compound that contains a mixture of dimethyl ether (75%) and propane (25%) has been recently reported as an effective treatment for warts. The present study aimed to evaluate the safety and efficacy of Wartner in male patients with genital warts.

METHODS: A Phase II parallel-randomized clinical trial was performed on 16 Iranian men affected by genital warts who were referred to a dermatology clinic at Tehran University of Medical Sciences. Two genital warts of each patient were selected and randomly assigned to receive either Wartner (intervention) or liquid nitrogen (control).

RESULTS: Two weeks after the treatment, the sizes of the lesions in control and intervention groups decreased by 17.87 ± 2.14 mmand 15.81 ± 1.80 mm, respectively (p = .299). Fourteen days after a single session of treatment, 81% of lesions in the control group and 50% in the Wartner group were completely eradicated, however, the difference was not statistically significant (p = .063).

CONCLUSIONS: The Wartner compound is as effective as the conventional cryotherapy method for treating genital warts. It is particularly valuable when there are contraindications or no access to common treatment options.
