PROCEDURE

实验过程

PLGA polymer (MW 24,000,160 mg) was dissolved in CH2Cl2 (1000 μL). Leuprolide acetate (40 mg) was dissolved in BnOH (1000 μL) and added to the polymer solution yielding a homogeneous organic phase. The resulting organic phase was combined with a 1% PVA aqueous phase containing 10 mM disodium pamoate to provide an emulsion. The emulsion was collected directly into a 0.3% PVA solvent extraction solution (100 mL) and stirred for 10 minutes. A secondary extraction solution consisting of 2% isopropanol (200 mL) was added and stirred for an additional four hours. Hardened microparticles were collected by filtration, washed with water, air dried and stored at 4° C. This provided formulation BJ (157 mg, 78.5% yield) with a median particle size 54.0 μm. The core load (9.4%), encapsulation efficiency (47.0%) and in vitro burst (5.31%) were determined by RP-HPLC assay.
