pH-Sensitive nanospheres for colon-specific drug delivery in experimentally induced colitis rat model.


Novel pH-sensitive nanospheres designed for colon-specific delivery were prepared using polymeric mixtures of poly (lactic-co-glycolic) acid (PLGA) and a pH-sensitive methacrylate copolymer. Budesonide (BSD), a topically active corticosteroid, was entrapped as a model drug. The therapeutic efficacy of the prepared nanospheres was assessed using the… (More)
