Atherosclerosis is a chronic disease that can lead to life‐threatening events such as myocardial infarction and stroke, is characterized by the build‐up of lipids and immune cells within the arterial wall. It is understood that inflammation is a hallmark of atherosclerosis and can be a target for therapy. In support of this concept, an injectable nanoliposomal formulation encapsulating fluocinolone acetonide (FA), a corticosteroid, is developed that allows for drug delivery to atherosclerotic plaques while reducing the systemic exposure to off‐target tissues. In this study, FA is successfully incorporated into liposomal nanocarriers of around 100 nm in size with loading efficiency of 90% and the formulation exhibits sustained release up to 25 d. The anti‐inflammatory effect and cholesterol efflux capability of FA‐liposomes are demonstrated in vitro. In vivo studies carried out with an apolipoprotein E‐knockout (Apoe−/−) mouse model of atherosclerosis show accumulation of liposomes in atherosclerotic plaques, colocalization with plaque macrophages and anti‐atherogenic effect over 3 weeks of treatment. This FA‐liposomal‐based nanocarrier represents a novel potent nanotherapeutic option for atherosclerosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
