Evaluation of the effect of ultrasonic waves on drug release from microspher microspheres prepared froms blend of poly trimethylene carbonate and poly adipic anhydride

摘要

There are many applications for microspheres infield of novel drug delivery. This type of drugdelivery syst systems can be provided by differentems methods such a as solvent evaporation, coacervation,s spray drying, hot melt, and so on. In this studyapplication of ulterasonic waves in formation ofmicrospheres and the effect of this factor on size,shape and drug release from particles will discussed.
