Nanostructured Delivery Systems for Curcumin: Improving Bioavailability and Plaque-Targeting Efficacy in...

Cardiovascular disease (CVD) encompasses ischemic conditions of the heart, brain, and bodily tissues, primarily resulting from hyperlipidemia, atherosclerosis (AS), hypertension, and other related factors. CVD accounts for over 40% of global non-communicable disease mortality, making it the leading cause of death and a significant medical burden worldwide. AS, the principal pathological basis for most cardiovascular diseases, is characterized as a chronic, sterile inflammatory condition triggered by lipid overload and various other factors. In recent years, natural bioactive compounds have gained prominence in the treatment of human diseases. Among these, curcumin (Cur) has garnered considerable attention due to its anti-inflammatory, lipid-lowering, antihypertensive, and endothelial protective properties. This review examines traditional pharmacological approaches for treating AS, with particular emphasis on the critical mechanisms through which Cur exerts its therapeutic effects. Additionally, it introduces novel nanoformulations designed to address the inherent limitations of Cur, providing valuable insights for researchers investigating its application in AS therapy.
