Effects of shell thickness of hollow poly(lactic acid) nanoparticles on sustained drug delivery for pharmacological treatment of glaucoma

Structural designing of carriers with extended drug release profiles is critically important for achieving long-acting drug delivery systems toward efficient managements of chronic diseases. Here, we present a strategy to exploit the effects of the shell thickness of hollow poly(lactic acid) nanoparticles (HPLA NPs) in sustained glaucoma therapy. Formulations based on pilocarpine-loaded HPLA NPs with tailorable shell thickness ranging from 10 to...
