This process is carried out by providing a solid drug that is scarcely soluble in water, dispersing the drug in water in the presence of a water-soluble high-molecular substance to form a disperse system containing the drug in the form of finely divided particles substantially not greater than 10μ in diameter, and then removing the water from the disperse system. | |
