[Pingyangmycin gelatin microspheres: preparation and drug release characteristics].
Pingyangmycin gelatin microspheres(PYM-GMS) was prepared by optimal double-phase emulsified condensation polymerization for the interventional Chemoembolization with carotid artery therapy, and its release characteristics were studied in vivo and in vitro. The results of three ways of administration(vein drop, artery perfusion and artery embolization) were compared. The experiment indicates that the diameter of PYM-GMS is more appropriate for the application in external carotid artery embolization with PYM-GMS, which significantly reduces the circulating drug level and the dosage, prolongs the time period of higher drug concentration, achieves the purpose of sustained release and targeted tumor therapy.
