Renal function testing: differentiation between a nephrotoxic agent and diuretic drugs.

abstract：:We report a programed drug delivery system that can tailor the release of anesthetic bupivacaine in a spatiotemporally controlled manner. The drug delivery system was developed through the combination of a collagen-based injectable hydrogel and 2 types of poly(lactic-co-glycolic acid) (PLGA) particles. As a rapid-rele...
