What are the uses of this medicine?[edit | edit source]

Fluvastatin (Lescol; Lescol XL) is used as an adjunctive therapy to diet to:

  • Reduce elevated total cholesterol (Total-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein B (Apo B), and triglyceride (TG) , and to increase high-density lipoprotein cholesterol (HDL-C) in adult patients with primary hypercholesterolemia and mixed dyslipidemia.
  • Reduce elevated TC, LDL-C, and Apo B levels in boys and post-menarchal girls, 10 to 16 years of age, with heterozygous familial hypercholesterolemia after failing an adequate trial of diet therapy.
  • Reduce the risk of undergoing revascularization procedures in patients with clinically evident CHD.
  • Slow the progression of atherosclerosis in patients with CHD.
  • Fluvastatin capsules are a prescription medicine called "statins" that lower cholesterol in your blood. They lower the "bad" cholesterol and triglycerides in your blood. They can raise your "good" cholesterol as well.
  • Fluvastatin capsules are for people whose cholesterol does not come down enough with exercise and a low-fat diet alone.

Fluvastatin capsules may be used in patients with heart disease (coronary artery disease) to:

  • lower the chances of heart problems which would require procedures to help restore blood flow to the heart.
  • slow the buildup of too much cholesterol in the arteries of the heart.
  • Treatment with fluvastatin capsules has not been shown to prevent heart attacks or stroke.

Limitations of Use:

  • Fluvastatin capsules have not been studied in conditions where the major abnormality is elevation of chylomicrons, VLDL, or IDL (i.e., hyperlipoproteinemia Types I, III, IV, or V).


How does this medicine work?[edit | edit source]

  • The sodium salt of a synthetic lipid-lowering agent with potential antineoplastic activity.
  • Fluvastatin competitively inhibits hepatic 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase, the enzyme that catalyzes the conversion of HMG-CoA to mevalonate, a key step in cholesterol synthesis.
  • This agent lowers plasma cholesterol and lipoprotein levels, and modulates immune responses through the suppression of MHC II (major histocompatibility complex II) on interferon gamma-stimulated, antigen-presenting cells such as human vascular endothelial cells.
  • Through the inhibition of mevalonate synthesis, statins, like fluvastatin, have been shown to inhibit the production of dolichol, geranylpyrophosphate (GPP) and farnesylpyrophosphate (FPP) and the isoprenylation of the intracellular G-proteins Ras and Rho, which may result in antiangiogenic, apoptotic, and antimetastatic effects in susceptible tumor cell populations.

What special precautions should I follow?[edit | edit source]

  • Rhabdomyolysis with acute renal failure secondary to myoglobinuria have been reported with fluvastatin capsules and other drugs in this class. Risks increase with advanced age (≥ 65), uncontrolled hypothyroidism, renal impairment, and combination use with cyclosporine ,or gemfibrozil. Advise patients to promptly report to their physician unexplained and/or persistent muscle pain, tenderness, or weakness and discontinue fluvastatin if myopathy is diagnosed or suspected.
  • Patients should be advised to report promptly any symptoms of myopathy. Fluvastatin capsules therapy should be discontinued if myopathy is diagnosed or suspected.
  • There have been rare reports of Immune-Mediated Necrotizing Myopathy (IMNM), an autoimmune myopathy, associated with statin use. IMNM is characterized by: proximal muscle weakness and elevated serum creatine kinase, which persist despite discontinuation of statin treatment; positive anti-HMG CoA reductase antibody; muscle biopsy showing necrotizing myopathy; and improvement with immunosuppressive agents.
  • Increases in serum transaminases (aspartate aminotransferase [AST]/serum glutamic-oxaloacetic transaminase, or alanine aminotransferase [ALT]/serum glutamic-pyruvic transaminase) have been reported with HMG-CoA reductase inhibitors, including fluvastatin sodium. Persistent elevations in hepatic transaminases can occur. Check liver enzyme tests before initiating therapy and as clinically indicated thereafter.
  • Increases in HbA1c and fasting serum glucose levels have been reported with HMG-CoA reductase inhibitors, including fluvastatin sodium. Patients treated with fluvastatin sodium who develop clinical evidence of endocrine dysfunction should be evaluated appropriately. Caution should be exercised if a statin or other agent used to lower cholesterol levels is administered to patients receiving other drugs (e.g., ketoconazole, spironolactone, cimetidine) that may decrease the levels of endogenous steroid hormones.
  • Women who are breastfeeding should not use fluvastatin capsules. Patients who have a lipid disorder and are breastfeeding should be advised to discuss the options with their healthcare professional.
  • It is associated with mild, asymptomatic and self-limited serum aminotransferase elevations during therapy and rarely with clinically apparent acute liver injury.
