摘要：We evaluated testosterone-containing lecithin reverse wormlike micelles (reverse worms) composed of a polar substance/lecithin/isopropyl myristate for transdermal application. Water, D-ribose, or tetraglycerol were used as the polar substance and were key ingredients for forming the reverse worms. Using the reverse worms, 1 wt% of testosterone could be stably solubilized. When using D-ribose as polar substance, the maximum zero-shear viscosity of the reverse worms solution was higher than that of systems using water or tetraglycerol as the polar substance. The mechanism of skin permeation of testosterone from reverse worms solution was elucidated using skin permeation experiments with hairless mouse skin. When the structure of the reverse worms transitioned to lamellar liquid crystals at the skin/formulation interface, testosterone became supersaturated in the formulations. The structural transition occurred in systems using water or D-ribose as the polar substance, increasing the flux of testosterone. The flux of testosterone from reverse worms solution thus depends on the type of polar substance used.
