Аннотация
BACKGROUND AND AIM: Acne vulgaris is a common inflammatory skin condition which is treated using Tretinoin (TRE), a widely used retinoid. Nano emulations (NEs) are colloidal nano-sized particles that enhance the therapeutic efficacy of TRE and minimize adverse effects. This study is aimed at developing a TRE-loaded NE (NE-TRE) and at assessing the therapeutic effects of the formulation in acne vulgaris lesions, compared to conventional 0.05% TRE emulsion.
METHOD: The high energy emulsification method was used to make NE-TRE. After obtaining stable NE, particle characterization and physicochemical properties were evaluated under accelerated conditions. Conducting a clinical study, we compared the therapeutic effects of NE-TRE and 0.05% TRE emulsion by comparing the number of acne lesions and porphyrin production in both sides of the face.
RESULTS AND CONCLUSION: We successfully developed stable nanoparticles. It was a stable oil-in-water emulsion with particle size of about 150 nm, and containing circular and separated particles. In a pilot clinical study, the number of acne lesions as well as the size and intensity of porphyrin production significantly reduced after topical application of NE-TRE. This formula shows proper efficiency and good loading capacity of TRE in the drug delivery system.
