[PROBLEMS] To further improve skin permeability for the practical application of an S / O preparation for transdermal drug delivery that is expected to have a systemic effect. An S / O preparation for transdermal drug delivery comprising a drug and a gold nanorod having an absorption band in a region of 650 to 2000 nm (preferably 680 to 1200 nm, more preferably 700 to 900 nm) is provided. Gold nanorods are biocompatible, preferably surface modified with polyethylene glycol. In a particularly preferred embodiment of the present invention, the drug is contained in a solid phase (S, dispersed phase) along with gold nanorods and a surfactant. [Selection] Figure 5 |
