Background: Photodynamic therapy which involves the use of photosensitizer molecule activated by a light source was proven very promising for treatment of dermatological diseases, especially the resistant ones such as recalcitrant plantar warts (PW).
Objective: However, its efficacy is hindered by the poor permeation of the photosensitizer molecule required to initiate skin photo-induced effects.
Methods: In this manuscript, the efficiency of nano-vesicular system (transfersomes) as potential topical drug delivery system for the photosensitizer methylene blue (MB) was investigated following clinical photodynamic therapy (PDT) in patients suffering from PW.
Results: Results revealed that MB transfersomal gel displayed higher complete healing percentage for the lesions compared to the free MB gel (86.67% versus 53.57%) achieved at lower number of treatment sessions (2.2 versus 4.14). Patients reported no signs of pain or inflammation, with no recurrence of the lesions during the follow up period of 8 months.
Conclusion: PDT using transfersomal MB as an effective and safe therapeutic modality for the treatment of PW.
