Intracellular drug concentration in RAW 264.7 macrophages cultured with un-encapsulated (Free) or Ace-DEX microparticles encapsulating AR-12 (AR-12/MPs). Drug concentration was measured in cell lysates by HPLC. The decrease in cell concentration at 10 µM is due to cytotoxicity, which is high above 5 µM of free drug.
