Fluvastatin has reduced total and LDL-cholesterol concentrations in a few patients with hypercholesterolemia associated with or exacerbated by diabetes mellitus (diabetic dyslipidemia), renal insufficiency,cardiac or renal transplantation, or nephrotic syndrome (nephrotic hyperlipidemia). Fluvastatin also has been shown to decrease proteinuria in patients with immunoglobulin A nephropathy. Additional studies are necessary to determine the role, if any, of fluvastatin therapy in patients with these disorders. /NOT included in US product label/

Fluvastatin capsules are contraindicated in women who are pregnant or may become pregnant. Serum cholesterol and triglycerides increase during normal pregnancy, and cholesterol or cholesterol derivatives are essential for fetal development. Fluvastatin capsules may cause fetal harm when administered to pregnant women. Atherosclerosis is a chronic process and the discontinuation of lipid-lowering drugs during pregnancy should have little impact on the outcome of long-term therapy of primary hypercholesterolemia. Fluvastatin capsules should be administered to women of childbearing age only when such patients are highly unlikely to conceive and have been informed of the potential hazards. If the patient becomes pregnant while taking this drug, fluvastatin capsules should be discontinued and the patient should be apprised of the potential hazard to the fetus.

To be used as an adjunct to dietary therapy to prevent cardiovascular events. May be used as secondary prevention in patients with coronary heart disease (CHD) to reduce the risk of requiring coronary revascularization procedures, for reducing progression of coronary atherosclerosis in hypercholesterolemic patients with CHD, and for the treatment of primary hypercholesterolemia and mixed dyslidipidemia.
FDA Label
Fluvastatin, the first synthetically-derived HMG-CoA reductase inhibitor, is a hydrophilic, acidic, antilipemic agent used to lower cholesterol and triglyceride levels associated with primary hypercholesterolemia and mixed dyslipidemia (Fredrickson types IIa and IIb), to slow the progression of coronary atherosclerosis in patients with CHD and as secondary prevention therapy in patients with CHD to reduce the risk of requiring coronary revascularization procedures. Although similar to lovastatin, simvastatin, and pravastatin, fluvastatin has a shorter half-life, no active metabolites, extensive protein binding, and minimal CSF penetration. Fluvastatin acts primarily in the liver. It is prepared as a racemate of two erythro enantiomers of which the 3R,5S enantiomer exerts the pharmacologic effect.
Absorption
Rapidly and almost completely absorbed (> 90%), but undergoes extensive first pass metabolism. Bioavailability is 24% (range 9-50%) when a 10 mg dose is given. The mean relative bioavailability of the extended-release tablet is 29% (range: 9% to 66%) compared to an immediate-release capsule administered under fasting conditions. When given orally, fluvastatin reaches peak concentrations (Tmax) in less than one hour. Taking the extended release tablet with a high-fat meal will delay absorption (Tmax = 6 hours) and increase bioavailability by approximately 50%. However, the maximum concentration of fluvastatin sodium extended-release tablets seen after a high fat meal is less than the peak concentration following a single dose or twice daily dose of the 40 mg fluvastatin capsule.
Route of Elimination
When orally administered, fluvastatin is primarily excreted in the faces ( ~90%) as metabolites, with less than 2% present as unchanged drug. Approximately 5% was recovered in the urine.

Undergoes hepatic metabolism primarily via hydroxylation of the indole ring at the 5- and 6-positions to 5-hydroxy fluvastatin and 6-hydroxy fluvastatin, respectively. N-dealkylation to N-desisopropyl fluvastatin and beta-oxidation of the side chain also occurs. Metabolized primarily by the CYP2C9 isozyme system (75%), and to a lesser extent by CYP3A4 (~20%) and CYP2C8 (~5%). Hydroxylated metabolites retain some pharmcological activity, but are present as conjugates (glucuronides and sulfates) in the blood and are rapidly eliminated via bile into feces. Both enantiomers of fluvastatin are metabolized in a similar manner. Fluvastatin also undergoes glucuronidation via UGT enzymes.
In vitro data indicate that fluvastatin metabolism involves multiple Cytochrome P450 (CYP) isozymes. CYP2C9 isoenzyme is primarily involved in the metabolism of fluvastatin (approximately 75%), while CYP2C8 and CYP3A4 isoenzymes are involved to a much less extent, i.e., approximately 5% and approximately 20%, respectively.

Fluvastatin selectively and competitively inhibits the hepatic enzyme hydroxymethylglutaryl-coenzyme A (HMG-CoA) reductase. HMG-CoA reductase is responsible for converting HMG-CoA to mevalonate, the rate-limiting step in cholesterol biosynthesis. Inhibition results in a decrease in hepatic cholesterol levels which stimulates the synthesis of LDL receptors and increases hepatic uptake of LDL cholesterol. The end result is decreased levels of plasma total and LDL cholesterol.
Fluvastatin sodium is a competitive inhibitor of HMG-CoA reductase, the rate limiting enzyme that converts 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) to mevalonate, a precursor of sterols, including cholesterol. The inhibition of cholesterol biosynthesis reduces the cholesterol in hepatic cells, which stimulates the synthesis of LDL receptors and thereby increases the uptake of LDL particles. The end result of these biochemical processes is a reduction of the plasma cholesterol concentration.

Statins are largely used in clinics in the treatment of patients with cardiovascular diseases for their effect on lowering circulating cholesterol. Lectin-like oxidized low-density lipoprotein (LOX-1), the primary receptor for ox-LDL, plays a central role in the pathogenesis of atherosclerosis and cardiovascular disorders. We have recently shown that chronic exposure of cells to lovastatin disrupts LOX-1 receptor cluster distribution in plasma membranes, leading to a marked loss of LOX-1 function. Here we investigated the molecular mechanism of statin-mediated LOX-1 inhibition and we demonstrate that all tested statins /including fluvastatin/ are able to displace the binding of fluorescent ox-LDL to LOX-1 by a direct interaction with LOX-1 receptors in a cell-based binding assay. Molecular docking simulations confirm the interaction and indicate that statins completely fill the hydrophobic tunnel that crosses the C-type lectin-like (CTLD) recognition domain of LOX-1. Classical molecular dynamics simulation technique applied to the LOX-1 CTLD, considered in the entire receptor structure with or without a statin ligand inside the tunnel, indicates that the presence of a ligand largely increases the dimer stability. Electrophoretic separation and western blot confirm that different statins binding stabilize the dimer assembly of LOX-1 receptors in vivo. The simulative and experimental results allow us to propose a CTLD clamp motion, which enables the receptor-substrate coupling. These findings reveal a novel and significant functional effect of statins.

Epidemiological studies suggest that statins (hydroxymethylglutaryl-CoA reductase inhibitors) could reduce the risk of Alzheimer disease. Although one possible explanation is through an effect on beta-amyloid (Abeta) metabolism, its effect remains to be elucidated. Here, we explored the molecular mechanisms of how statins influence Abeta metabolism. Fluvastatin at clinical doses significantly reduced Abeta and amyloid precursor protein C-terminal fragment (APP-CTF) levels among APP metabolites in the brain of C57BL/6 mice. Chronic intracerebroventricular infusion of lysosomal inhibitors blocked these effects, indicating that up-regulation of the lysosomal degradation of endogenous APP-CTFs is involved in reduced Abeta production. Biochemical analysis suggested that this was mediated by enhanced trafficking of APP-CTFs from endosomes to lysosomes, associated with marked changes of Rab proteins, which regulate endosomal function. In primary neurons, fluvastatin enhanced the degradation of APP-CTFs through an isoprenoid-dependent mechanism. Because our previous study suggests additive effects of fluvastatin on Abeta metabolism, we examined Abeta clearance rates by using the brain efflux index method and found its increased rates at high Abeta levels from brain. As LRP1 in brain microvessels was increased, up-regulation of LRP1-mediated Abeta clearance at the blood-brain barrier might be involved. In cultured brain microvessel endothelial cells, fluvastatin increased LRP1 and the uptake of Abeta, which was blocked by LRP1 antagonists, through an isoprenoid-dependent mechanism. Overall, the present study demonstrated that fluvastatin reduced Abeta level by an isoprenoid-dependent mechanism. ...
