Pharmacological Profile and Mechanisms of Cardiovascular Protective Effects of Statins: An Update

Abstract This review article highlights recent developments in the clinical pharmacology of statins. A thorough literature search was performed using PubMed Central, Scopus, and Google Scholar, focusing on keywords related to statin kinetics, mechanisms, cardiovascular protection, side effects, and variations in individual responses. Understanding the pharmacokinetics of statins is essential for maximizing their therapeutic effects while reducing side effects and potential drug interactions. Statins have varying degrees of lipophilicity, resulting in different kinetic profiles that affect their bioavailability, elimination, and interactions with other drugs. The main mechanism by which statins lower cholesterol in blood is by inhibiting liver 3-hydroxy-3-methylglutaryl-CoA reductase, thereby increasing low-density lipoprotein receptor expression on hepatocytes and decreasing its plasma levels. This will ultimately reduce the risk of cardiovascular events. Statins also have antithrombotic and anti-inflammatory effects by increasing the availability of nitric oxide, inhibiting procoagulant proteins, and inhibiting platelet activation, all of which contribute to cardiovascular protection. Several clinical evidences support the effectiveness of statins in preventing venous thromboembolism and acute coronary syndrome. However, statins are associated with an increased risk of new-onset diabetes, particularly with high-intensity statins, necessitating careful monitoring in high-risk patients. Additionally, there is variability in patient responses to statin therapy, influenced by genetic polymorphisms and biological differences, highlighting the need for personalized treatment strategies. As clinical guidelines continue to evolve, incorporating genetic and biological factors will be vital for optimizing statin therapy and managing cardiovascular risks. In conclusion, there is substantial evidence that statins still play a vital role in preventing cardiovascular disease, necessitating a comprehensive approach that combines pharmacological interventions with lifestyle modifications to enhance patient outcomes.
