Interventional Cardiology Clinics: Mechanisms Underlying Drug Delivery to Peripheral Arteries.

Li J, Tzafriri R, Patel SM, Parikh SA. Mechanisms Underlying Drug Delivery to Peripheral Arteries.

Summary: Delivery of drugs onto arterial targets via endovascular devices commands several principles: dissolution, diffusion, convection, drug binding, barriers to absorption, and interaction between the drug, delivery vehicle, and accepting arterial wall. The understanding of drug delivery in the coronary vasculature is vast; there is ongoing work needed in the peripheral arteries. There are differences that account for some failures of application of coronary technology into the peripheral vascular space. Breakthroughs in peripheral vascular interventional techniques building on current technologies require investigators willing to acknowledge the similarities and differences between these different vascular territories, while developing technologies adapted for peripheral arteries.
