Research on preparation and quality control of drug-carried poly lactic-co-glycolic acid microbubble / 生物医学工程学杂志

ABSTRACT

This research was aimed to develop the technique and formula for the preparation of stable and effective microbubbles containing hydrophilic drugs. We prepared EB-PLGA microbubbles and evaluated its drug loading and burst release to choose the best technique and formula. The result of optimizing formula was W1/O (115), EB-PLGA (0.04), PVA (5%). The burst release decreased after the addition of supplemental agent and the change of method for preparation. We concluded that the optimizing formula could elevate drug loading and decrease burst release obviously.
