Abstract
A product for preventing and treating external genitalia infection and/or flat warts is provided, wherein the product comprises a chloroquine nanosphere. The chloroquine nanosphere comprises a water-soluble nanosphere carrier, and chloroquine or a chloroquine derivative. A mass ratio of the chloroquine or the chloroquine derivative to the water-soluble nanosphere carrier during preparation ranges from 1:3 to 1:5. A loading rate of the chloroquine or the chloroquine derivative in the prepared chloroquine nanosphere ranges from 3.0% to 21.6%. The water-soluble nanosphere carrier is water-soluble chitosan; a deacetylation degree of the water-soluble chitosan ranges from 80% to 95%, and a viscosity-average molecular weight thereof ranges from 3000 to 5000 g/mol. The chloroquine derivative is selected from one or more of hydroxychloroquine, chloroquine phosphate or chloroquine sulfate.
