Abstract
AbstractObjectiveThe objective of this work was to develop a self‐emulsifying drug delivery system (SEDDS) containing caffeine for the treatment of cellulite.MethodsSEDDS were prepared using the solution method. 0.5% (w/v) caffeine was added to the previously selected excipients. The system was characterized by droplet size, zeta potential, emulsification time and long‐term stability. In vitro release and skin permeation were investigated using Franz‐type diffusion cells. The cytotoxicity was evaluated on normal human keratinocytes.ResultsCaffeine SEDDS were thermodynamically stable, with a zeta potential less than ‐ 22 mV and droplet size around 30 nm, and were long‐term stable. The permeation study showed that the formulation promoted caffeine accumulation in the skin layers, suggesting an increase in local circulation. Cytotoxicity studies on HaCaT cells were not conclusive as the surfactant used indicated false‐positive results due to its high molar mass.ConclusionIt was possible to obtain a stable SEDDS that could cause an increase in blood flow in the applied area, resulting in cellulite reduction.
