ACCELERATED RELEASE TESTING METHOD FOR SUSTAINED RELEASE MICROPARTICLES

摘要

PURPOSE: An accelerated release testing method for sustained release fine particles is provided to remarkably reduce time and labor required for measuring release fine particles. CONSTITUTION: An accelerated release testing method for sustained release fine particles is as follows. An elution rate is measured in a water solution with a material activated as a surfactant. The water solution has a pH 1~4. The material activated as the surfactant comprises one or more of polyvinyl alcohol, polysorbate surfactants, a methyl cellulose group.
