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.
