PARTICULATE POLY(LACTIC-CO-GLYCOLIC) ACID, METHOD FOR MANUFACTURING PARTICULATE POLY(LACTIC-CO-GLYCOLIC) ACID, AND PARTICULATE POLY(LACTIC-CO-GLYCOLIC) ACID MANUFACTURING APPARATUS

摘要

A particulate poly(lactic-co-glycolic) acid (PLGA) is provided. The particulate PLGA comprises a poly(lactic-co-glycolic) acid (PLGA), and has an average volume-based particle diameter of 80 nm or less and a relative span factor (R.S.F.) satisfying the following formula (1):; ;where R.S.F, is defined by (D90−D10)/D50, where D90, D50, and D10 respectively represent particle diameters at cumulative rates of 90%, 50%, and 10% by volume based on a cumulative particle size distribution counted from a small-particle side.
