Fluvastatin Sodium is the sodium salt of Fluvastatin, a member of the statin class of compounds used as an active pharmaceutical ingredient (API) in the treatment of hypercholesterolemia and dyslipidemia. It functions by competitively inhibiting HMG-CoA reductase, the rate-limiting enzyme in hepatic cholesterol biosynthesis, which lowers LDL cholesterol levels and modestly increases HDL cholesterol while reducing triglycerides. This API is employed in formulations to reduce the risk of cardiovascular events, including in patients post-coronary interventions where it helps stabilize atherosclerotic plaques. As a high-purity chemical (≥97.5%), it is suitable for pharmaceutical research, development, and manufacturing applications. Extended-release formulations of the final drug product provide once-daily dosing for consistent efficacy.
