    摘要： Nanoparticles containing retinoic acid have reduced irritancy of retinoic acid and are suitable for subcutaneous or intravenous administration, as well as for use in sustained-release preparation. The high skin permeability of the nanoparticles makes them suitable for use in pharmaceutical or non-pharmaceutical external preparations or cosmetics intended for skin application. The present invention provides a method for adjusting the particle size of such nanoparticles and nanoparticles produced by such a method. Specifically, the method involves dispersing retinoic acid dissolved in a lower alcohol in an aqueous alkali solution; adding a nonionic surfactant to the dispersion to form a mixed micelle; adding to the micelle a halide or acetate of divalent metal along with a carbonate or phosphate of alkali metal so that the molar ratio of the former to the latter is 1:0 to 1:1.0, thereby depositing a coating of inorganic salt of polyvalent metal on the surface of the micelle; and adjusting the average particle size of the resulting nanoparticles to 5 to 300 nm. The inorganic salt of polyvalent metal may be calcium carbonate, zinc carbonate, or calcium phosphate.

    摘要： A composition contains nanoparticles of retinoic acid as an active ingredient. The nanoparticles have reduced irritancy of retinoic acid and are suitable for subcutaneous or intravenous administration, as well as for use in sustained-release preparation. The high skin permeability of the nanoparticles makes the composition suitable for use in pharmaceutical or non-pharmaceutical external preparations or cosmetics intended for skin application. The retinoic acid nanoparticles of the present invention are coated with an inorganic salt of polyvalent metal and can be dissolved in water to make a stable clear solution that can be formulated into injectable preparations for subcutaneous and intravenous administration. The polyvalent metal inorganic salt coating helps reduce the irritancy of retinoic acid, so that the nanoparticles do not cause inflammation or tumor formation at the site of application. The inorganic salt of polyvalent metal may be calcium carbonate, zinc carbonate or calcium phosphate.

    摘要： To provide an external preparation or injectable preparation that exerts the effect of enabling transdermal or transmucosal in viva absorption of fat-soluble drugs and water-soluble drugs not having been satisfactorily attained hitherto and that contains a highly absorbable fat-soluble/water-soluble drug, the injectable preparation especially aiming at sustained-release and target effects. In particular, drug-containing nanoparticles (secondary nanoparticles) are provided by causing primary nanoparticles containing a fat-soluble drug or fat-solubilized water-soluble drug to act with a bivalent or trivalent metal salt. Further, drug-containing nanoparticles (tertiary nanoparticles) are provided by first causing primary nanoparticles containing a fat-soluble drug or fat-solubilized water-soluble drug to act with a bivalent or trivalent metal salt to thereby obtain secondary nanoparticles and thereafter causing a monovalent to trivalent basic salt to act on the secondary nanoparticles. Still further, there are provided a process for producing these nanoparticles, and a transdermal or transmucosal external preparation or injectable preparation in which these nanoparticles are contained.
