Summary: The demand for drug delivery systems (DDSs) has increased due to the ambiguity of certain diseases and the potential toxicity of many medicines. Nanomedicine, specifically the use of nanocarriers and medication formulations, has become a unique concept for enhanced drug bioaccessibility, long-term drug administration, and dose reduction. Among various nanomedicine techniques, polymeric nanoparticles (poly-NPs) have shown great potential in improving drug pharmacokinetics. However, the safety and toxicity of poly-NPs in long-term studies using high doses remain poorly understood. This article discusses the toxicity of nanoparticles (NPs) used in DDSs, including polylactide-co-glycolide, polylactic acid, polycaprolactone, and poly(alkyl cyanoacrylates).
