摘要:
The present invention provides a method for producing a controlled release microsphere with mean average size greater than 50 μm, comprising preparing a water-in-oil (w/o) emulsion comprising an inner aqueous layer containing a pharmaceutically effective amount of a biologically active polypeptide with activity similar to parathyroid hormone, and an oil layer containing a polymer substance of poly(lactic-co-glycolic acid) (PLGA), then adding the w/o emulsion into aqueous polyvinyl alcohol (PVA) solution to form a water-in-oil-in-water (w/o/w) double emulsion and then desorbing the solvent in the oil layer. The present invention also provides a controlled release microsphere prepared by the method and use thereof.
