4 Contraindications
Fluvastatin sodium extended-release tablets are contraindicated in patients with:
- Acute liver failure or decompensated cirrhosis [see Warnings and Precautions (5.3)].
- Hypersensitivity to fluvastatin or any of the excipients in fluvastatin sodium extended-release tablets. Hypersensitivity reactions, including anaphylaxis, angioedema, and Stevens-Johnson syndrome have been reported [see Adverse Reactions (6.2)].
- Acute liver failure or decompensated cirrhosis (4)
- Hypersensitivity to fluvastatin or any excipient in fluvastatin sodium extended-release tablets (4)
5warnings And Precautions
- Myopathy and Rhabdomyolysis: Risk factors include age 65 years or greater, uncontrolled hypothyroidism, renal impairment, and concomitant use with certain other drugs. Discontinue fluvastatin if markedly elevated creatine kinase (CK) levels occur, or myopathy is diagnosed or suspected. Temporarily discontinue fluvastatin in patients experiencing an acute or serious condition at high risk of developing renal failure secondary to rhabdomyolysis. Inform patients of the risk of myopathy and rhabdomyolysis when starting or increasing fluvastatin dosage. Instruct patients to promptly report unexplained muscle pain, tenderness, or weakness, particularly if accompanied by malaise or fever. (5.1)
- Immune-Mediated Necrotizing Myopathy (IMNM): Rare reports of IMNM, an autoimmune myopathy, have been reported with statin use. Discontinue fluvastatin if IMNM is suspected. (5.2)
- Hepatic Dysfunction: Increases in serum transaminases have occurred, some persistent. Rare reports of fatal and non-fatal hepatic failure have occurred. Consider testing liver enzyme before initiating therapy and as clinically indicated thereafter. If serious hepatic injury with clinical symptoms and/or hyperbilirubinemia or jaundice occurs, promptly discontinue fluvastatin sodium extended-release tablets (5.3)
5.1 Myopathy and Rhabdomyolysis
Fluvastatin may cause myopathy (muscle pain, tenderness, or weakness associated with elevated creatine kinase [CK]) and rhabdomyolysis. Acute kidney injury secondary to myoglobinuria and rare fatalities have occurred as a result of rhabdomyolysis with statins, including fluvastatin.
Myopathy, defined as muscle aching or muscle weakness in conjunction with increases in CK, values to greater than 10 times the upper limit of normal (ULN) was < 0.1% in fluvastatin clinical trials [see Adverse Reactions (6.1)].
Risk Factors for Myopathy
Risk factors for myopathy include age 65 years or greater, uncontrolled hypothyroidism, renal impairment, and concomitant use with certain other drugs (including other lipid-lowering therapies) [see Drug Interactions (7.1)].
Steps to Prevent or Reduce the Risk of Myopathy and Rhabdomyolysis
Avoid concomitant use of fluvastatin with gemfibrozil, cyclosporin, and fluconazole. When used concomitantly with fluvastatin, lipid modifying doses (≥ 1 g/day) of niacin, fibrates, and colchicine may also increase the risk of myopathy and rhabdomyolysis [see Drug Interactions (7.1)].
Discontinue fluvastatin if markedly elevated CK levels occur or if myopathy is either diagnosed or suspected. Muscle symptoms and CK increases may resolve if fluvastatin is discontinued. Temporarily discontinue fluvastatin in patients experiencing an acute or serious condition at high risk of developing renal failure secondary to rhabdomyolysis, e.g., sepsis, shock, severe hypovolemia, major surgery, trauma, severe metabolic, endocrine, or electrolyte disorders, or uncontrolled epilepsy.
Inform patients of the risk of myopathy and rhabdomyolysis when starting fluvastatin. Instruct patients to promptly report any unexplained muscle pain, tenderness, or weakness, particularly if accompanied by malaise or fever.
5.2 Immune-Mediated Necrotizing Myopathy
There have been rare reports of immune-mediated necrotizing myopathy (IMNM), an autoimmune myopathy, associated with statin use, including reports of recurrence when the same or a different statin was administered. IMNM is characterized by proximal muscle weakness and elevated serum CK, which persist despite discontinuation of statin treatment; positive anti-HMG CoA reductase antibody, muscle biopsy showing necrotizing myopathy, and improvement with immunosuppressive agents. Additional neuromuscular and serologic testing may be necessary. Treatment with immunosuppressive agents may be required. Discontinue fluvastatin if IMNM is suspected.
5.3 Hepatic Dysfunction
Increases in serum transaminases have been reported with use of fluvastatin [see Adverse Reactions (6.1)].In most cases, these changes appeared soon after initiation, were transient, were not accompanied by symptoms, and resolved or improved on continued therapy or after a brief interruption in therapy. Persistent increases to more than three times the ULN in serum transaminases have occurred in approximately 1.1% of patients receiving fluvastatin in clinical trials. Marked persistent increases of hepatic transaminases have also occurred with fluvastatin. There have been rare post-marketing reports of fatal and non-fatal hepatic failure in patients taking statins, including fluvastatin.
Patients who consume substantial quantities of alcohol and/or have a history of liver disease may be at increased risk for hepatic injury.
Consider liver enzyme testing before fluvastatin initiation and thereafter, when clinically indicated. Fluvastatin sodium extended-release tablets are contraindicated in patients with acute liver failure or decompensated cirrhosis [see Contraindications (4)].If serious hepatic injury with clinical symptoms and/or hyperbilirubinemia or jaundice occurs, promptly discontinue fluvastatin sodium extended-release tablets.
5.4 Increases in HbA1c and Fasting Serum Glucose Levels
Increases in HbA1c and fasting serum glucose levels have been reported with statins, including fluvastatin. Optimize lifestyle measures, including regular exercise, maintaining a healthy body weight, and making healthy food choices.

6.1 Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
In the fluvastatin capsule, clinical trials there were 2,326 patients treated with fluvastatin (age range, 18 to 75 years, 44% women, 94% White, 4% Black or African American, 2% other ethnicities) with a median treatment duration of 24 weeks. The most common adverse reactions that led to treatment discontinuation and occurred at an incidence greater than placebo were: transaminase increased (0.8%), upper abdominal pain (0.3%), dyspepsia (0.3%), fatigue (0.2%), and diarrhea (0.2%).
In the fluvastatin sodium extended-release tablets clinical trials there were 912 patients treated with fluvastatin sodium extended-release tablets (age range, 21 to 87 years, 52% women, 91% White, 4% Black of African American, 5% other ethnicities) with a median treatment duration of 24 weeks. The most common adverse reactions that led to treatment discontinuation were abdominal pain (0.7%), diarrhea (0.5%), nausea (0.4%), dyspepsia (0.4%) and chest pain (0.3%).
Adverse reactions occurring in the fluvastatin capsules and fluvastatin sodium extended-release tablets controlled trials with a frequency 2% included the following:

Elevations in Liver Enzyme Tests
Approximately 1.1% of patients treated with fluvastatin capsules in clinical trials developed dose-related, persistent elevations of serum transaminase levels to more than 3 times the ULN. Fourteen of these patients (0.6%) were discontinued from therapy. In all clinical trials, a total of 33/2,969 patients (1.1%) had persistent transaminase elevations with an average fluvastatin exposure of approximately 71.2 weeks; 19 of these patients (0.6%) were discontinued. The majority of patients with these abnormal biochemical findings were asymptomatic.
In a pooled analysis of all placebo-controlled studies in which fluvastatin capsules were used, persistent transaminase elevations (> 3 times the ULN on two consecutive weekly measurements) occurred in 0.2%, 1.5%, and 2.7% of patients treated with daily doses of 20, 40, and 80 mg (titrated to 40 mg twice daily) fluvastatin capsules, respectively. Ninety-one percent of the cases of persistent ALT/AST increased abnormalities (20 of 22 patients) occurred within 12 weeks of therapy and in all patients with persistent liver function test abnormalities there was an abnormal liver function test present at baseline or by Week 8.
In the pooled analysis of 24-week controlled trials, persistent transaminase elevation occurred in 1.9%, 1.8%, and 4.9% of patients treated with fluvastatin sodium extended-release tablets 80 mg, fluvastatin capsules 40 mg and fluvastatin capsules 40 mg twice daily, respectively. In 13 of 16 patients treated with fluvastatin sodium extended-release tablets the abnormality occurred within 12 weeks of initiation of treatment with fluvastatin sodium extended-release tablets 80 mg.
6.2 Postmarketing Experience
The following adverse reactions have been identified during postapproval use of fluvastatin. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Musculoskeletal:Muscle cramps, myopathy, rhabdomyolysis, arthralgias, muscle spasms, muscle weakness, myositis. There have been rare reports of IMNM associated with statin use [see Warnings and Precautions (5.2)].
Neurological:Dysfunction of certain cranial nerves (including alteration of taste, impairment of extra-ocular movement, facial paresis), tremor, vertigo, paresthesia, hypoesthesia, dysesthesia, peripheral neuropathy, peripheral nerve palsy. There have been rare postmarketing reports of cognitive impairment (e.g., memory loss, forgetfulness, amnesia, memory impairment, confusion) associated with the use of all statins. The reports are generally nonserious, and reversible upon statin discontinuation, with variable times to symptom onset (1 day to years) and symptom resolution (median of 3 weeks). There have been rare reports of new-onset or exacerbation of myasthenia gravis, including ocular myasthenia, and reports of recurrence when the same or a different statin was administered.
Psychiatric:Anxiety, depression, psychic disturbances
Respiratory:Interstitial lung disease
Hypersensitivity reactions:An apparent hypersensitivity syndrome has been reported rarely which has included one or more of the following features: anaphylaxis, angioedema, lupus erythematosus-like syndrome, polymyalgia rheumatica, vasculitis, purpura, thrombocytopenia, leukopenia, hemolytic anemia, positive ANA, ESR (erythrocyte sedimentation rate) increase, eosinophilia, arthritis, arthralgia, urticaria, asthenia, photosensitivity reaction, fever, chills, flushing, malaise, dyspnea, toxic epidermal necrolysis, erythema multiforme, including Stevens-Johnson syndrome.

7.1 Drug Interactions That Increase the Risk of Myopathy and Rhabdomyolysis with Fluvastatin
Table 3 includes a ul of drugs that increase the risk of myopathy and rhabdomyolysis when used concomitantly with fluvastatin and instructions for preventing or managing them [see Warnings and Precautions (5.1), Clinical Pharmacology (12.3)].
Table 3. Drug Interactions That Increase the Risk of Myopathy and Rhabdomyolysis with Fluvastatin Gemfibrozil Clinical impact There is an increased risk of myopathy/rhabdomyolysis when fluvastatin is administered with gemfibrozil Intervention Avoid concomitant use of gemfibrozil with fluvastatin. Cyclosporine Clinical impact Cyclosporine coadministration increases fluvastatin exposure. The risk of myopathy and rhabdomyolysis may be increased with concomitant use of cyclosporine with fluvastatin. Intervention Avoid concomitant use of cyclosporine with fluvastatin. Fluconazole Clinical impact Fluconazole coadministration increases fluvastatin exposure. The risk of myopathy and rhabdomyolysis may be increased with concomitant use of fluconazole with fluvastatin. Intervention Avoid concomitant use of fluconazole with fluvastatin Niacin Clinical impact Risk of myopathy and rhabdomyolysis may be enhanced with concomitant use with lipid-modifying doses (≥ 1 g/day) of niacin with fluvastatin. Intervention Consider if the benefit of using lipid-modifying doses (≥ 1 g/day) of niacin concomitantly with fluvastatin outweighs the increased risk of myopathy and rhabdomyolysis. If concomitant use is decided, monitor patients for signs and symptoms of myopathy, particularly during initiation of therapy and during upward dose titration. Fibrates Clinical impact Fibrates may cause myopathy when given alone. The risk of myopathy and rhabdomyolysis may be increased with concomitant use of fibrates with fluvastatin. Intervention Consider if the benefit of using fibrates concomitantly with fluvastatin outweighs the increased risk of myopathy and rhabdomyolysis. If concomitant use is decided, monitor patients for signs and symptoms of myopathy, particularly during initiation of therapy and during upward dose titration. Colchicine Clinical impact Cases of myopathy and rhabdomyolysis have been reported with concomitant use of colchicine with fluvastatin. Intervention Consider if the benefit of using colchicine concomitantly with fluvastatin outweighs the increased risk of myopathy and rhabdomyolysis. If concomitant use is decided, monitor patients for signs and symptoms of myopathy, particularly during initiation of therapy and during upward dose titration. 7.2 Fluvastatin Effects on Other Drugs

8use In Specific Populations
- Pregnancy: May cause fetal harm (8.1)
- Lactation: Breastfeeding not recommended during treatment with fluvastatin (8.2)
8.1Pregnancy
Risk Summary
Discontinue fluvastatin when pregnancy is recognized. Alternatively, consider the ongoing therapeutic needs of the individual patient. Fluvastatin decreases synthesis of cholesterol and possibly other biologically active substances derived from cholesterol; therefore, fluvastatin may cause fetal harm when administered to pregnant patients based on the mechanism of action [see Clinical Pharmacology (12.1)]. In addition, treatment of hyperlipidemia is not generally necessary during pregnancy. 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 hyperlipidemia for most patients.
Available data from case series and prospective and retrospective observational cohort studies over decades of use with statins in pregnant women have not identified a drug-associated risk of major congenital malformations. Published data from prospective and retrospective observational cohort studies with fluvastatin use in pregnant women are insufficient to determine if there is a drug-associated risk of miscarriage (see Data).
In animal reproduction studies, no adverse developmental effects were observed in pregnant rats or rabbits orally administered fluvastatin during the period of organogenesis at doses that resulted in 2 and 5 times, respectively, the human exposure at the maximum recommended human dosage of 40 mg/day, based on body surface area (mg/m 2) (see Data).
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
Data
Human Data
A Medicaid cohort linkage study of 1,152 statin-exposed pregnant women compared to 886,996 controls did not find a significant teratogenic effect from maternal use of statins in the first trimester of pregnancy, after adjusting for potential confounders, including maternal age, diabetes mellitus, hypertension, obesity, and alcohol and tobacco use using propensity score-based methods. The relative risk of congenital malformations between the group with statin use and the group with no statin use in the first trimester was 1.07 (95% CI: 0.85 to 1.37) after controlling for confounders, particularly preexisting diabetes mellitus. There were also no statistically significant increases in any of the organ-specific malformations assessed after accounting for confounders. In the majority of pregnancies, statin treatment was initiated prior to pregnancy and was discontinued at some point in the first trimester when pregnancy was identified. Study limitations include reliance on physician coding to define the presence of a malformation, lack of control for certain confounders such as body mass index, use of prescription dispensing as verification for the use of a statin, and lack of information on non-live births.
Animal Data
Fluvastatin sodium given to rats during organogenesis at doses of 12 mg/kg/day and in rabbits at doses of 10 mg/kg/day produced delays in skeletal development. These doses resulted in 2 times (rat at 12 mg/kg) or 5 times (rabbit at 10 mg/kg) the 40 mg human exposure based on mg/m 2surface area. Malaligned thoracic vertebrae were seen in rats at 36 mg/kg, a dose that produced significant maternal toxicity. A study in which female rats were given fluvastatin during the third trimester at 12 and 24 mg/kg/day resulted in maternal mortality at or near term and postpartum. In addition, fetal and neonatal lethality were apparent. No effects on the dam or fetus occurred at 2 mg/kg/day. A second study at levels of 2, 6, 12 and 24 mg/kg/day confirmed the findings in the first study with neonatal mortality beginning at 6 mg/kg. Rats were given fluvastatin from Gestation Day 15 to Lactation Day 21 at doses of 12 or 24 mg/kg/day with or without the presence of concurrent supplementation with mevalonic acid, a product of HMG-CoA reductase which is essential for cholesterol biosynthesis. The concurrent administration of mevalonic acid completely prevented the maternal and neonatal mortality but did not prevent low body weights in pups at 24 mg/kg on Days 0 and 7 postpartum.
8.2 Lactation
Risk Summary
There is no information about the presence of fluvastatin in human milk, the effects of the drug on the breastfed infant or the effects of the drug on milk production. However, it has been shown that another drug in this class passes into human milk. Studies in rats have shown that fluvastatin and/or its metabolites are present in the milk of lactating rats. When a drug is present in animal milk, it is likely that the drug will be present in human milk (see Data).Statins, including fluvastatin, decrease cholesterol synthesis and possibly the synthesis of other biologically active substances derived from cholesterol and may cause harm to the breastfed infant.
Because of the potential for serious adverse reactions in a breastfed infant, based on the mechanism of action, advise patients that breastfeeding is not recommended during treatment with fluvastatin [see Use in Specific Populations (8.1), Clinical Pharmacology (12.1)].
Data
Following a single oral administration of 1 mg/kg of radioactive fluvastatin to lactating rats, the concentration of total radioactivity was determined. Fluvastatin and/or its metabolites were measured in the breast milk at a 2:1 ratio (milk:plasma).
8.4Pediatric Use
The safety and effectiveness of fluvastatin as an adjunct to diet to reduce LDL-C have been established in pediatric patients 10 years of age and older with HeFH. Use of fluvastatin for this indication is based on open-label, uncontrolled clinical trials in 114 pediatric patients 9 years of age and older with HeFH. In these limited uncontrolled studies, there was no significant effect on growth or sexual maturation in the males or females, or on menstrual cycle length in females.
The safety and effectiveness of fluvastatin have not been established in pediatric patients younger than 10 years of age with HeFH or in pediatric patients with other types of hyperlipidemia (other than HeFH).
8.5Geriatric Use
Fluvastatin exposures were not significantly different between the nonelderly and elderly populations (age ≥ 65 years) [see Clinical Pharmacology (12.3)].
Advanced age (≥ 65 years) is a risk factor for fluvastatin-associated myopathy and rhabdomyolysis. Dose selection for an elderly patient should be cautious, recognizing the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy and the higher risk of myopathy. Monitor geriatric patients receiving fluvastatin for the increased risk of myopathy [see Warnings and Precautions (5.1)].
8.6 Renal Impairment
Renal impairment is a risk factor for myopathy and rhabdomyolysis. Dose adjustments for mild to moderate renal impairment are not necessary. Fluvastatin has not been studied at doses greater than 40 mg in patients with severe renal impairment; therefore, use fluvastatin with caution in patients with severe renal impairment. Monitor all patients with renal impairment for development of myopathy [see Warnings and Precautions (5.1), Clinical Pharmacology (12.3)].
8.7 Hepatic Impairment
Fluvastatin is contraindicated in patients with acute liver failure or decompensated cirrhosis [see Contraindications (4), Warnings and Precautions (5.3)].
10overdosage
No specific antidotes for fluvastatin are known. In the event of an overdose of fluvastatin, consider contacting the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdosage management recommendations.
11description
Fluvastatin sodium inhibits 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase.
Fluvastatin sodium is [R*,S*-(E)]-(±)-7-[3-(4-fluorophenyl)-1-(1-methylethyl)-1H-indol-2-yl]- 3,5-dihydroxy-6-heptenoic acid, monosodium salt. The empirical formula of fluvastatin sodium is C24H25FNO4•Na, its molecular weight is 433.46 g/mol and its structural formula is:
Fluvastatin sodium, USP is a white to pale yellow, brownish-pale yellow, or reddish-pale yellow, hygroscopic powder soluble in alcohol, in methanol, and in water. Fluvastatin sodium extended-release tablets are supplied as extended-release tablets containing fluvastatin sodium, equivalent to 80 mg of fluvastatin, for oral use. Fluvastatin sodium extended-release tablets contain the following inactive ingredients: glycerol dibehenate, pregelatinized starch, hypromellose, potassium bicarbonate, magnesium stearate, polyvinyl alcohol, titanium dioxide, talc, lecithin (soya), yellow iron oxide non-irradiated, shellac glaze (modified) in SD-45, isopropyl alcohol, black iron oxide non-irradiated, N-butyl alcohol, propylene glycol, ammonium hydroxide.
12clinical Pharmacology
12.1Mechanism of Action
Fluvastatin 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 cholesterol.
12.2 Pharmacodynamics
Inhibition of HMG-CoA reductase by fluvastatin accelerates the expression of LDL-receptors, followed by the uptake of LDL-C from blood to the liver, leading to a decrease in plasma LDL-C and total cholesterol. Sustained inhibition of cholesterol synthesis in the liver also decreases levels of very-low-density lipoproteins. The maximum LDL-C reduction of fluvastatin is usually achieved by 4 weeks and is maintained after that.
12.3Pharmacokinetics
Absorption
Fluvastatin administered as fluvastatin sodium extended-release 80 mg tablets reaches peak concentration in approximately 3 hours under fasting conditions, after a low-fat meal, or 2.5 hours after a low-fat meal. The mean relative bioavailability of the extended-release tablet is approximately 29% (range, 9% to 66%) compared to that of the fluvastatin immediate-release capsule administered under fasting conditions. Administration of a high-fat meal delayed the absorption (Tmax 6h) and increased the bioavailability of the extended-release tablet 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.
Distribution
Fluvastatin is 98% bound to plasma proteins. The mean volume of distribution (VDss) is estimated at 0.35 L/kg. At therapeutic concentrations, the protein binding of fluvastatin is not affected by warfarin, salicylic acid and glyburide.
Elimination
Metabolism
Fluvastatin is metabolized in the liver, primarily via hydroxylation of the indole ring at the 5- and 6-positions. N-dealkylation and beta-oxidation of the side-chain also occurs. The hydroxy metabolites have some pharmacologic activity, but do not circulate in the blood. Fluvastatin has two enantiomers. Both enantiomers of fluvastatin are metabolized in a similar manner.
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.
Excretion
Following oral administration, fluvastatin is primarily (about 90%) excreted in the feces as metabolites, with less than 2% present as unchanged drug. Approximately 5% of a radiolabeled oral dose were recovered in urine. The elimination half-life (t 1/2) of fluvastatin is approximately 3 hours.
Specific Populations
Geriatric Patients
Plasma levels of fluvastatin are not significantly different in patients age > 65 years compared to patients age 21 to 49 years.
Gender
In a study evaluating the effect of age and gender on fluvastatin pharmacokinetics, there were no significant differences in fluvastatin exposures between males and females, except between younger females and younger males (both ages 21-49 years), where there was an approximate 30% increase in area under the curve (AUC) in females. Adjusting for body weight decreases the magnitude of the differences seen. For fluvastatin sodium extended-release tablets, the AUC increases 67% and 77% for women compared to men under fasted and high-fat meal fed conditions, respectively.
Pediatric Patients
Pharmacokinetic data in the pediatric population are not available.
Patients with Renal Impairment
In patients with moderate to severe renal impairment (CLCr 10-40 mL/min), AUC and Cmax increased approximately 1.2-fold after administration of a single dose of 40 mg fluvastatin compared to healthy volunteers. In patients with end-stage renal disease on hemodialysis, the AUC increased by approximately 1.5-fold. Fluvastatin sodium extended-release tablets were not evaluated in patients with renal impairment [see Use in Specific Populations (8.6)].However, systemic exposures after administration of fluvastatin sodium extended-release tablets are lower than after the 40 mg immediate release capsule.
Patients with Hepatic Impairment
In patients with hepatic impairment due to liver cirrhosis, fluvastatin AUC and Cmax increased approximately 2.5-fold compared to healthy subjects after administration of a single 40 mg dose [see Use in Specific Populations (8.7)].The enantiomer ratios of the two isomers of fluvastatin in hepatic impairment patients were comparable to those observed in healthy subjects.
Drug Interaction Studies
Data from drug-drug interactions studies involving coadministration of gemfibrozil, niacin, itraconazole, erythromycin, tolbutamide or clopidogrel indicate that the PK disposition of fluvastatin is not significantly altered when fluvastatin is coadministered with any of these drugs.
The below uled drug interaction information is derived from studies using fluvastatin capsules. Similar studies have not been conducted using the fluvastatin sodium extended-release tablets.

13nonclinical Toxicology
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
In a 2-year carcinogenicity study in rats at doses of 6, 9, and 18 to 24 (escalated after 1 year) mg/kg/day, there was an increased incidence of thyroid follicular cell adenomas and carcinomas in males treated with 18 to 24 mg/kg/day. Additionally, a low incidence of forestomach squamous papillomas and one forestomach carcinoma were observed at the 18 to 24 mg/kg/day dose, likely due to prolonged direct contact exposure rather than a systemic effect. This dose represents a plasma AUC exposure approximately 26 to 35 times the mean human plasma drug concentration after a 40 mg oral dose.
A carcinogenicity study conducted in mice at doses of 0.3, 15 and 30 mg/kg/day revealed a statistically significant increase in forestomach squamous cell papillomas in females at 15 mg/kg/day and in males and females at 30 mg/kg/day. These doses represent plasma AUC exposures approximately 2 and 7 times the mean human plasma drug concentration after a 40 mg oral dose.
No evidence of mutagenicity was observed in vitro, with or without rat-liver metabolic activation, in the following studies: microbial mutagen tests using mutant strains of Salmonella typhimurium or Escherichia coli; malignant transformation assay in BALB/3T3 cells; unscheduled DNA synthesis in rat primary hepatocytes; chromosomal aberrations in V79 Chinese Hamster cells; HGPRT V79 Chinese Hamster cells. In addition, there was no evidence of genotoxicity in vivo in either a rat chromosome aberration study or mouse micronucleus test.
In a fertility study in rats with daily doses up to 6 mg/kg/day for females and 20 mg/kg/day for males, fluvastatin sodium had no adverse effects on the fertility or reproductive performance.
Hamsters treated for 3 months at 20 mg/kg/day (approximately three times the 40 mg human daily dose based on body surface area, mg/m 2) showed small seminal vesicles and testes, along with tubular degeneration and aspermatogenesis in the testes and vesiculitis in the seminal vesicles. Rats treated for 2 years at 18 mg/kg/day (approximately four times human exposure based on body surface area) exhibited vesiculitis in the seminal vesicles and edema in the testes.
14clinical Studies
Secondary Prevention of Cardiovascular Disease
In the Fluvastatin Capsules Intervention Prevention Study (LIPS), the effect of fluvastatin capsules 40 mg administered twice daily on the risk of recurrent cardiac events (time to first occurrence of cardiac death, nonfatal myocardial infarction, or revascularization) was assessed in 1,677 adult patients with CHD who had undergone a percutaneous coronary intervention (PCI) procedure (mean time from PCI to randomization = 3 days). In this multicenter, randomized, double-blind, placebo-controlled trial, patients were treated with dietary/lifestyle counseling and either fluvastatin 40 mg (n = 844) or placebo (n = 833) given twice daily for a median of 3.9 years. The study population was 84% male, 98% White, with 37% > 65 years of age. Mean baseline lipid concentrations were: total cholesterol 201 mg/dL, LDL-C 132 mg/dL, triglycerides 70 mg/dL, and HDL-C 39 mg/dL.
Fluvastatin capsules significantly reduced the risk of recurrent cardiac events (Figure 1) by 22% (p = 0.013, 181 patients in the fluvastatin capsules group versus 222 patients in the placebo group). Revascularization procedures comprised the majority of the initial recurrent cardiac events (143 revascularization procedures in the fluvastatin capsules group and 171 in the placebo group). Consistent trends in risk reduction were observed in patients > 65 years of age.
Figure 1. Primary Endpoint – Recurrent Cardiac Events (Cardiac Death, Nonfatal MI or Revascularization Procedure) (ITT Population)
Outcome data for the Fluvastatin Capsules Intervention Prevention Study are shown in Figure 2. After exclusion of revascularization procedures (CABG and repeat PCI) occurring within the first 6 months of the initial procedure involving the originally instrumental site, treatment with fluvastatin capsules was associated with a 32% (p = 0.002) reduction in risk of late revascularization procedures (CABG or PCI occurring at the original site > 6 months after the initial procedure, or at another site).
Figure 2. Fluvastatin Capsules Intervention Prevention Study - Primary and Secondary Endpoints
In the Lipoprotein and Coronary Atherosclerosis Study (LCAS), the effect of fluvastatin capsule therapy on coronary atherosclerosis was assessed by quantitative coronary angiography (QCA) in patients with CAD and mild to moderate hypercholesterolemia (baseline LDL-C range 115 to 190 mg/dL). In this randomized double-blind, placebo-controlled trial, 429 patients were treated with conventional measures (Step 1, AHA Diet) and either fluvastatin 40 mg/day or placebo. In order to provide treatment to patients receiving placebo with LDL-C levels ≥ 160 mg/dL at baseline, adjunctive therapy with cholestyramine was added after Week 12 to all patients in the study with baseline LDL-C values of ≥ 160 mg/dL, which were present in 25% of the study population. Quantitative coronary angiograms were evaluated at baseline and 2.5 years in 340 (79%) angiographic evaluable patients.
Compared to placebo, fluvastatin capsules significantly slowed the progression of coronary atherosclerosis as measured by within-patient per-lesion change in minimum lumen diameter (MLD), the primary endpoint (Figure 3 below), percent diameter stenosis (Figure 4), and the formation of new lesions (13% of all fluvastatin patients versus 22% of all placebo patients). A significant difference in favor of fluvastatin capsules was found between all fluvastatin and all placebo patients in the distribution among the three categories of definite progression, definite regression, and mixed or no change. Beneficial angiographic results (change in MLD) were independent of patients’ gender and consistent across a range of baseline LDL-C levels.

Figure 4. Change in % Diameter Stenosis
Primary Hyperlipidemia in Adults
Fluvastatin sodium extended-release tablets have been studied in five controlled trials of adult patients with primary hyperlipidemia and mixed dyslipidemia. Fluvastatin sodium extended-release tablets were administered to over 900 patients in trials from 4 to 26 weeks in duration. In the three largest of these trials, fluvastatin sodium extended-release tablets given as a single daily dose of 80 mg significantly reduced Total-C, LDL-C, TG, and Apo B (Table 5).
In patients with primary mixed dyslipidemia as defined by baseline plasma TG levels ≥ 200 mg/dL and < 400 mg/dL, treatment with fluvastatin produced significant decreases in Total-C, LDL-C, TG, and Apo B (see Table 7).

HeFH in Pediatric Patients Aged 10 Years and Older
Fluvastatin capsules were studied in two open-label, uncontrolled, dose-titration trials. The first trial enrolled 29 pre-pubertal males, 9 to 12 years of age, who had an LDL-C level > 90th percentile for age and one parent with primary hypercholesterolemia and either a family history of premature ischemic heart disease or tendon xanthomas. The mean baseline LDL-C was 226 mg/dL (range, 137 to 354 mg/dL). All patients were started on fluvastatin capsules 20 mg daily with dose adjustments every 6 weeks to 40 mg daily then 80 mg daily (40 mg twice daily) to achieve an LDL-C goal between 97 to 124 mg/dL. Endpoint analyses were performed at Year 2. Fluvastatin decreased plasma levels of Total-C and LDL-C by 21% and 27%, respectively. The mean achieved LDL-C was 161 mg/dL (range, 74 to 336 mg/dL).
The second trial enrolled 85 male and female patients, 10 to 16 years of age, who had an LDL-C > 190 mg/dL or LDL-C > 160 mg/dL and one or more risk factors for coronary heart disease, or LDL-C > 160 mg/dL and a proven LDL-receptor defect. The mean baseline LDL-C was 225 mg/dL (range, 148 to 343 mg/dL). All patients were started on fluvastatin capsules 20 mg daily with dose adjustments every 6 weeks to 40 mg daily then 80 mg daily (fluvastatin sodium 80 mg extended-release tablets) to achieve an LDL-C goal of < 130 mg/dL. Endpoint analyses were performed at Week 114. Fluvastatin decreased plasma levels of Total-C and LDL-C by 22% and 28%, respectively. The mean achieved LDL-C was 159 mg/dL (range, 90 to 295 mg/dL).
The majority of patients in both trials (83% in the first trial and 89% in the second trial) were titrated to the maximum daily dose of 80 mg.

PATIENT INFORMATION FLUVASTATIN SODIUM EXTENDED-RELEASE TABLETS (fluvastatin) extended-release tablets, for oral use
You must read and follow all instructions before using fluvastatin sodium extended-release tablets.
Read this Patient Information before you start taking fluvastatin sodium extended-release tablets and each time you get a refill. There may be new information. This information does not take the place of talking with your healthcare provider about your medical condition or your treatment. If you have any questions about fluvastatin sodium extended-release tablets, ask your doctor or pharmacist.
What are fluvastatin sodium extended-release tablets?
Fluvastatin sodium extended-release tablets are prescription medicines “that contain the cholesterol lowering medicine, fluvastatin.”
Fluvastatin sodium extended-release tablets are used in adults with heart disease (coronary artery disease) to:
- lower the need for heart and blood vessel procedures to improve flow to the heart, called coronary revascularization.
- slow the buildup of too much cholesterol in the arteries of the heart.
Fluvastatin sodium extended-release tablets are used along with diet to lower the level of:
- low-density lipoprotein cholesterol (LDL-C) or “bad” cholesterol in adults with hyperlipidemia (high levels of fat in the blood)
- LDL-C in adults and children 10 years of age and older with heterozygous familial hypercholesterolemia (HeFH), an inherited condition that causes high levels of LDL, who require 80 mg of fluvastatin daily.
The safety and effectiveness of fluvastatin has not been established in children younger than 10 years of age with heterozygous familial hypercholesterolemia (HeFH) or in children with other types of hyperlipidemia (high levels in fat in the blood) other than HeFH.
Do not take fluvastatin sodium extended-release tablets if you:
- have liver problems (acute liver failure or decompensated cirrhosis)
- are allergic to fluvastatin or any of the ingredients in fluvastatin sodium extended-release tablets. See the end of this Patient Information leaflet for a complete ul of ingredients in fluvastatin sodium extended-release tablets.
