Nano-scale drug delivery systems for antiarrhythmic agents

Arrhythmia means the heart is beating too fast, too slow, or with an irregular pattern. Due to the side effects and low bioavailability of many antiarrhythmic drugs, nano-encapsulation has been widely used for their targeted delivery. Lipid nanocapsules, nano liposomes, nano niosomes, solid lipid nanoparticles and polymeric nanoparticles are common nano-carriers used for this purpose. The aim of this article is to summarize some of nano systems used for the specific delivery of antiarrhythmic agents to target tissues. At first, nanotechnology and its applications in drug delivery are described in brief. Then, some information on arrhythmias and antiarrhythmic drugs are provided. Finally, the nano drug delivery systems are explained and examples of their applications in encapsulation of antiarrhythmic drugs are presented. (C) 2018 Published by Elsevier Masson SAS.
