Abstract
A method of producing a medicinal nanoparticle suspension is provided, wherein a medicinal ingredient added in a suspending solution is ground to form nanoparticles of the medicinal ingredient by irradiating the suspending solution with a laser. The process is implemented after adding a poorly water-soluble or water-insoluble medicinal ingredient of a drug in a poor solvent to form the suspending solution.
Claims8
A method of producing a medicinal nanoparticle suspension, comprising the steps of:
- adding a poorly water-soluble or water-insoluble medicinal ingredient of a drug into a poor solvent to form a suspending solution;
- and
- irradiating the suspending solution with a laser having a wavelength that is absorbed by the medicinal ingredient to grind the medicinal ingredient in the suspending solution to form nanoparticles.
