DRUGS & SUPPLEMENTS
Fluvastatin Retard uses
1 INDICATIONS AND USAGE
Therapy with lipid-altering agents should be only one component of multiple risk factor intervention in individuals at significantly increased risk for atherosclerotic vascular disease due to hypercholesterolemia. Drug therapy is indicated as an adjunct to diet when the response to a diet restricted in saturated fat and cholesterol and other non-pharmacologic measures alone has been inadequate.
Fluvastatin Retard capsules are an HMG-CoA reductase inhibitor indicated as an adjunctive therapy to diet to:
Limitations of Use:
1.1 Hypercholesterolemia (Heterozygous Familial and Nonfamilial) and Mixed Dyslipidemia
Fluvastatin Retard capsules are indicated
The NCEP classification of cholesterol levels in pediatric patients with a familial history of hypercholesterolemia or premature CVD is summarized below.
Children treated with Fluvastatin Retard in adolescence should be re-evaluated in adulthood and appropriate changes made to their cholesterol-lowering regimen to achieve adult treatment goals.
1.2 Secondary Prevention of Cardiovascular Disease
In patients with clinically evident CHD, Fluvastatin Retard capsules are indicated to:
1.3 Limitations of Use
Fluvastatin Retard 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).
2 DOSAGE AND ADMINISTRATION
2.1 General Dosing Information
Dose range: 20 mg to 80 mg/day.
Fluvastatin Retard capsules can be administered orally as a single dose, with or without food.
Do not open Fluvastatin Retard capsules prior to administration.
Do not take two Fluvastatin Retard capsules, 40 mg at one time.
Since the maximal effect of a given dose is seen within 4 weeks, periodic lipid determinations should be performed at this time and dosage adjusted according to the patient’s response to therapy and established treatment guidelines.
For patients requiring LDL-C reduction to a goal of ≥ 25%, the recommended starting dose is 40 mg as one capsule in the evening, or 80 mg in divided doses of the 40 mg capsule given twice daily. For patients requiring LDL-C reduction to a goal of < 25% a starting dose of 20 mg may be used.
2.2 Adult Patients With Hypercholesterolemia and Mixed Dyslipidemia
Adult patients can be started on Fluvastatin Retard capsules. The recommended starting dose for Fluvastatin Retard capsules is one 40 mg capsule in the evening, or one Fluvastatin Retard capsule, 40 mg twice daily. Do not take two Fluvastatin Retard capsules, 40 mg at one time.
2.3 Pediatric Patients With Heterozygous Familial Hypercholesterolemia
The recommended starting dose is one Fluvastatin Retard capsule, 20 mg. Dose adjustments, up to a maximum daily dose administered as Fluvastatin Retard capsules, 40 mg twice daily should be made at 6 week intervals. Doses should be individualized according to the goal of therapy [see NCEP Pediatric Panel Guidelines and CLINICAL STUDIES (14)]1.

2.4 Use With Cyclosporine
Do not exceed a dose of 20 mg b.i.d. Fluvastatin Retard capsules in patients taking cyclosporine [see Drug Interactions ].
2.5 Use With Fluconazole
Do not exceed a dose of 20 mg b.i.d. Fluvastatin Retard capsules in patients taking fluconazole [see Drug Interactions (7.2)].
3 DOSAGE FORMS AND STRENGTHS
Fluvastatin Retard capsules: 20 mg, 40 mg (3)
4.1 Hypersensitivity to any Component of This Medication
Fluvastatin Retard capsules are contraindicated in patients with hypersensitivity to any component of this medication.
4.2 Active Liver Disease
Fluvastatin Retard capsules are contraindicated in patients with active liver disease or unexplained, persistent elevations in serum transaminases [see Warnings and Precautions ].
Fluvastatin Retard 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 Retard 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 Retard 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 Retard capsules should be discontinued and the patient should be apprised of the potential hazard to the fetus [see Use in Specific Populations (8.1)].
4.4 Nursing Mothers
Fluvastatin Retard is secreted into the breast milk of animals and because HMG-CoA reductase inhibitors have the potential to cause serious adverse reactions in nursing infants, women who require treatment with Fluvastatin Retard capsules should be advised not to breastfeed their infants [see Use in Specific Populations (8.3)].
5 WARNINGS AND PRECAUTIONS
5.1 Skeletal Muscle
Rhabdomyolysis with acute renal failure secondary to myoglobinuria have been reported with Fluvastatin Retard capsules and other drugs in this class.
Fluvastatin Retard capsules should be prescribed with caution in patients with predisposing factors for myopathy. These factors include advanced age (> 65 years), renal impairment, and inadequately treated hypothyroidism.
The risk of myopathy and/or rhabdomyolysis with statins is increased with concurrent therapy with cyclosporine, erythromycin, fibrates or niacin. Myopathy was not observed in a clinical trial in 74 patients involving patients who were treated with Fluvastatin Retard sodium together with niacin. Isolated cases of myopathy have been reported during postmarketing experience with concomitant administration of Fluvastatin Retard sodium and colchicine. No information is available on the pharmacokinetic interaction between Fluvastatin Retard sodium and colchicine.
Uncomplicated myalgia has also been reported in Fluvastatin Retard sodium-treated patients [see Adverse Reactions (6)]. In clinical trials, uncomplicated myalgia has been observed infrequently in patients treated with Fluvastatin Retard sodium at rates indistinguishable from placebo. Myopathy, defined as muscle aching or muscle weakness in conjunction with increases in CPK values to greater than 10 times the upper limit of normal, was < 0.1% in Fluvastatin Retard clinical trials. Myopathy should be considered in any patient with diffuse myalgias, muscle tenderness or weakness, and/or marked elevation of CPK.
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; muscle biopsy showing necrotizing myopathy without significant inflammation; improvement with immunosuppressive agents.
All patients should be advised to promptly report to their physician unexplained muscle pain, tenderness, or weakness, particularly if accompanied by malaise or fever or if muscle signs and symptoms persist after discontinuing Fluvastatin Retard.
Fluvastatin Retard sodium therapy should be discontinued if markedly elevated CPK levels occur or myopathy is diagnosed or suspected. Fluvastatin Retard sodium therapy should also be temporarily withheld in any patient experiencing an acute or serious condition predisposing to the development of renal failure secondary to rhabdomyolysis, e.g., sepsis; hypotension; major surgery; trauma; severe metabolic, endocrine, or electrolyte disorders; or uncontrolled epilepsy.
5.2 Liver Enzymes
Increases in serum transaminases have been reported with HMG-CoA reductase inhibitors, including Fluvastatin Retard sodium. In most cases, the elevations were transient and resolved or improved on continued therapy or after a brief interruption in therapy.
Approximately 1.1% of patients treated with Fluvastatin Retard capsules in worldwide trials developed dose-related, persistent elevations of serum transaminase levels to more than 3 times the upper limit of normal. Fourteen of these patients (0.6%) were discontinued from therapy. In all clinical trials, a total of 33/2969 patients (1.1%) had persistent transaminase elevations with an average Fluvastatin Retard sodium 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 Retard capsules were used, persistent transaminase elevations (> 3 times the upper limit of normal [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 Retard capsules, respectively. Ninety-one percent of the cases of persistent liver function test 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 the 24 week controlled trials, persistent transaminase elevation occurred in 1.8% and 4.9% of patients treated with Fluvastatin Retard capsules, 40 mg and Fluvastatin Retard capsules, 40 mg twice daily, respectively.
It is recommended that liver enzyme tests be performed prior to the initiation of Fluvastatin Retard sodium, and if signs or symptoms of liver injury occur.
There have been rare postmarketing reports of fatal and non-fatal hepatic failure in patients taking statins, including Fluvastatin Retard. If serious liver injury with clinical symptoms and/or hyperbilirubinemia or jaundice occurs during treatment with Fluvastatin Retard sodium, promptly interrupt therapy. If an alternate etiology is not found do not restart Fluvastatin Retard sodium.
In very rare cases, possibly drug-related hepatitis was observed that resolved upon discontinuation of treatment.1 Active liver disease or unexplained serum transaminase elevations are contraindications to the use of Fluvastatin Retard sodium [see Contraindications (4) and Warnings and Precautions (5.2)]. Caution should be exercised when Fluvastatin Retard sodium is administered to patients with a history of liver disease or heavy alcohol ingestion [see Clinical Pharmacology (12.3)]. Such patients should be closely monitored.
5.3 Endocrine Effects
Increases in HbA1c and fasting serum glucose levels have been reported with HMG-CoA reductase inhibitors, including Fluvastatin Retard sodium.
Statins interfere with cholesterol synthesis and lower circulating cholesterol levels and, as such, might theoretically blunt adrenal or gonadal steroid hormone production.
Fluvastatin Retard sodium exhibited no effect upon non-stimulated cortisol levels and demonstrated no effect upon thyroid metabolism as assessed by measurement of thyroid stimulating hormone (TSH). Small declines in total serum testosterone have been noted in treated groups, but no commensurate elevation in LH occurred, suggesting that the observation was not due to a direct effect upon testosterone production. No effect upon FSH in males was noted. Due to the limited number of premenopausal females studied to date, no conclusions regarding the effect of Fluvastatin Retard sodium upon female sex hormones may be made.
Two clinical studies in patients receiving Fluvastatin Retard at doses up to 80 mg daily for periods of 24 to 28 weeks demonstrated no effect of treatment upon the adrenal response to ACTH stimulation. A clinical study evaluated the effect of Fluvastatin Retard at doses up to 80 mg daily for 28 weeks upon the gonadal response to HCG stimulation. Although the mean total testosterone response was significantly reduced (p < 0.05) relative to baseline in the 80 mg group, it was not significant in comparison to the changes noted in groups receiving either 40 mg of Fluvastatin Retard or placebo.
Patients treated with Fluvastatin Retard 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.
5.4 CNS Toxicity
CNS effects, as evidenced by decreased activity, ataxia, loss of righting reflex, and ptosis were seen in the following animal studies: the 18 month mouse carcinogenicity study at 50 mg/kg/day, the 6 month dog study at 36 mg/kg/day, the 6 month hamster study at 40 mg/kg/day, and in acute, high-dose studies in rats and hamsters (50 mg/kg), rabbits (300 mg/kg) and mice (1500 mg/kg). CNS toxicity in the acute high-dose studies was characterized (in mice) by conspicuous vacuolation in the ventral white columns of the spinal cord at a dose of 5000 mg/kg and (in rats) by edema with separation of myelinated fibers of the ventral spinal tracts and sciatic nerve at a dose of 1500 mg/kg. CNS toxicity, characterized by periaxonal vacuolation, was observed in the medulla of dogs that died after treatment for 5 weeks with 48 mg/kg/day; this finding was not observed in the remaining dogs when the dose level was lowered to 36 mg/kg/day. CNS vascular lesions, characterized by perivascular hemorrhages, edema, and mononuclear cell infiltration of perivascular spaces, have been observed in dogs treated with other members of this drug class. No CNS lesions have been observed after chronic treatment for up to 2 years with Fluvastatin Retard in the mouse (at doses up to 350 mg/kg/day), rat (up to 24 mg/kg/day), or dog (up to 16 mg/kg/day).
Prominent bilateral posterior Y suture lines in the ocular lens were seen in dogs after treatment with 1, 8, and 16 mg/kg/day for 2 years.
6 ADVERSE REACTIONS
The following serious adverse reactions are discussed in greater detail in other sections of the label:
Most frequent adverse reactions (rate ≥ 2% and > placebo) are: headache, dyspepsia, myalgia, abdominal pain and nausea (6.1)
To report SUSPECTED ADVERSE REACTIONS, contact TEVA USA, PHARMACOVIGILANCE at 1-888-838-2872 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
6.1 Clinical Studies Experience in Adult Patients
Because clinical studies on Fluvastatin Retard capsules are conducted in varying study populations and study designs, the frequency of adverse reactions observed in the clinical studies of Fluvastatin Retard capsules cannot be directly compared with that in the clinical studies of other statins and may not reflect the frequency of adverse reactions observed in clinical practice.
In the Fluvastatin Retard capsules placebo-controlled clinical trials database of 2326 patients treated with Fluvastatin Retard capsules1 (age range 18 to 75 years, 44% women, 94% Caucasians, 4% Blacks, 2% other ethnicities) with a median treatment duration of 24 weeks, 3.4% of patients on Fluvastatin Retard capsules and 2.3% patients on placebo discontinued due to adverse reactions regardless of causality. 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%).
Clinically relevant adverse experiences occurring in the Fluvastatin Retard capsules controlled studies with a frequency ≥ 2%, regardless of causality, included the following:
Fluvastatin Retard Capsules Intervention Prevention Study
In the Fluvastatin Retard Capsules Intervention Prevention Study, the effect of Fluvastatin Retard capsules, 40 mg, administered twice daily on the risk of recurrent cardiac events was assessed in 1677 patients with CHD who had undergone a percutaneous coronary intervention (PCI) procedure. This was a multicenter, randomized, double-blind, placebo-controlled study, patients were treated with dietary/lifestyle counseling and either Fluvastatin Retard capsules, 40 mg (n = 844) or placebo (n = 833) given twice daily for a median of 3.9 years [see Clinical Studies (14.3)].
6.2 Clinical Studies Experience in Pediatric Patients
In patients aged < 18 years, efficacy and safety have not been studied for treatment periods longer than two years.
In two open-label, uncontrolled studies, 66 boys and 48 girls with heterozygous familial hypercholesterolemia were treated with Fluvastatin Retard sodium administered as Fluvastatin Retard capsules, 20 mg to 40 mg twice daily, or Fluvastatin Retard sodium extended-release tablets, 80 mg [see Clinical Studies (14.2) and Use in Specific Populations (8.4)].
6.3 Postmarketing Experience
Because adverse reactions from spontaneous reports are reported voluntarily from a population of uncertain size, it is generally not possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The following effects have been reported with drugs in this class. Not all the effects listed below have necessarily been associated with Fluvastatin Retard sodium therapy.
Musculoskeletal: muscle cramps, myalgia, myopathy, rhabdomyolysis, arthralgias, muscle spasms, muscle weakness, myositis.
There have been rare reports of immune-mediated necrotizing myopathy associated with statin use [see Warnings and Precautions (5.1)].
Neurological: dysfunction of certain cranial nerves (including alteration of taste, impairment of extra-ocular movement, facial paresis), tremor, dizziness, 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 statin use. These cognitive issues have been reported for 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).
Psychiatric: anxiety, insomnia, 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.
Gastrointestinal: pancreatitis, hepatitis, including chronic active hepatitis, cholestatic jaundice, fatty change in liver, cirrhosis, fulminant hepatic necrosis, hepatoma, anorexia, vomiting, fatal and non-fatal hepatic failure.
Skin: rash, dermatitis, including bullous dermatitis, eczema, alopecia, pruritus, a variety of skin changes (e.g., nodules, discoloration, dryness of skin/mucous membranes, changes to hair/nails).
Reproductive: gynecomastia, loss of libido, erectile dysfunction.
Eye: progression of cataracts (lens opacities), ophthalmoplegia.
Laboratory abnormalities: elevated transaminases, alkaline phosphatase, gamma-glutamyl transpeptidase and bilirubin; thyroid function abnormalities.
7 DRUG INTERACTIONS
Cyclosporine coadministration increases Fluvastatin Retard exposure. Therefore, in patients taking cyclosporine, therapy should be limited to Fluvastatin Retard 20 mg twice daily [see Warnings and Precautions (5.1) and Clinical Pharmacology (12.3)].
Administration of Fluvastatin Retard 40 mg single dose to healthy volunteers pre-treated with fluconazole for 4 days results in an increase of Fluvastatin Retard exposure. Therefore, in patients taking fluconazole, therapy should be limited to Fluvastatin Retard 20 mg twice daily [see Clinical Pharmacology ].
Due to an increased risk of myopathy/rhabdomyolysis when HMG-CoA reductase inhibitors are coadministered with gemfibrozil, concomitant administration of Fluvastatin Retard sodium with gemfibrozil should be avoided.
7.4 Other Fibrates
Because it is known that the risk of myopathy during treatment with HMG-CoA reductase inhibitors is increased with concurrent administration of other fibrates, Fluvastatin Retard sodium should be administered with caution when used concomitantly with other fibrates [see Warnings and Precautions and Clinical Pharmacology (12.3)].
The risk of skeletal muscle effects may be enhanced when Fluvastatin Retard sodium is used in combination with lipid-modifying doses (≥ 1 g/day) of niacin; a reduction in Fluvastatin Retard sodium dosage should be considered in this setting [see Warnings and Precautions (5.1)].
Concomitant administration of Fluvastatin Retard and glyburide increased glyburide exposures. Patients on concomitant therapy of glyburide and Fluvastatin Retard should continue to be monitored appropriately [see Clinical Pharmacology ].
Concomitant administration of Fluvastatin Retard and phenytoin increased phenytoin exposures. Patients should continue to be monitored appropriately when Fluvastatin Retard therapy is initiated or when Fluvastatin Retard dose is changed [see Clinical Pharmacology (12.3)].
Bleeding and/or increased prothrombin times have been reported in patients taking coumarin anticoagulants concomitantly with other HMG-CoA reductase inhibitors. Therefore, patients receiving warfarin-type anticoagulants should have their prothrombin times closely monitored when Fluvastatin Retard sodium is initiated or the dosage of Fluvastatin Retard sodium is changed.
Cases of myopathy, including rhabdomyolysis, have been reported with Fluvastatin Retard coadministered with colchicine, and caution should be exercised when prescribing Fluvastatin Retard with colchicine.
8 USE IN SPECIFIC POPULATIONS
Pregnancy Category X
Fluvastatin Retard sodium is contraindicated in women who are or may become pregnant [see Contraindications ].
Lipid lowering drugs are contraindicated during pregnancy, because cholesterol and cholesterol derivatives are needed for normal fetal development. Serum cholesterol and triglycerides increase during normal pregnancy. Atherosclerosis is a chronic process, and discontinuation of lipid-lowering drugs during pregnancy should have little impact on long-term outcomes of primary hypercholesterolemia therapy.
There are no adequate and well-controlled studies of use with Fluvastatin Retard sodium during pregnancy. Rare reports of congenital anomalies have been received following intrauterine exposure to other statins. In a review2 of about 100 prospectively followed pregnancies in women exposed to other statins, the incidences of congenital anomalies, spontaneous abortions, and fetal deaths/stillbirths did not exceed the rate expected in the general population. The number of cases is adequate only to exclude a 3 to 4 fold increase in congenital anomalies over background incidence. In 89% of prospectively followed pregnancies, drug treatment was initiated prior to pregnancy and was discontinued at some point in the first trimester when pregnancy was identified.
Teratology studies with Fluvastatin Retard in rats and rabbits showed maternal toxicity at high dose levels, but there was no evidence of embryotoxic or teratogenic potential [see Nonclinical Toxicology (13)].
Fluvastatin Retard sodium should be administered to women of child-bearing potential only when such patients are highly unlikely to conceive and have been informed of the potential hazards. If a woman becomes pregnant while taking Fluvastatin Retard sodium, the drug should be discontinued and the patient advised again as to the potential hazards to the fetus.
8.3 Nursing Mothers
Based on animal data, Fluvastatin Retard is present in breast milk in a 2:1 ratio (milk:plasma). Because of the potential for serious adverse reactions in nursing infants, nursing women should not take Fluvastatin Retard sodium [see Contraindications (4)].
8.4 Pediatric Use
The safety and efficacy of Fluvastatin Retard sodium in children and adolescent patients 9 to 16 years of age with heterozygous familial hypercholesterolemia have been evaluated in open-label, uncontrolled clinical trials for a duration of two years. The most common adverse events observed were influenza and infections. In these limited uncontrolled studies, there was no detectable effect on growth or sexual maturation in the adolescent boys or on menstrual cycle length in girls [see Clinical Studies, Adverse Reactions (6.3), and Dosage and Administration (2.2)]. Adolescent females should be counseled on appropriate contraceptive methods while on Fluvastatin Retard sodium therapy [see Contraindications (4)].
8.5 Geriatric Use
Fluvastatin Retard exposures were not significantly different between the nonelderly and elderly populations (age ≥ 65 years) [see Clinical Pharmacology (12.3)]. Since advanced age (≥ 65 years) is a predisposing factor for myopathy, Fluvastatin Retard sodium should be prescribed with caution in the elderly.
8.6 Hepatic Impairment
Fluvastatin Retard sodium is contraindicated in patients with active liver disease or unexplained, persistent elevations in serum transaminases [see Clinical Pharmacology ].
8.7 Renal Impairment
Dose adjustments for mild to moderate renal impairment are not necessary. Fluvastatin Retard has not been studied at doses greater than 40 mg in patients with severe renal impairment; therefore caution should be exercised when treating such patients at higher doses [see Clinical Pharmacology (12.3)].
To date, there has been limited experience with overdosage of Fluvastatin Retard. If an overdose occurs, it should be treated symptomatically with laboratory monitoring and supportive measures should be instituted as required. The dialyzability of Fluvastatin Retard sodium and of its metabolites in humans is not known at present [seeWarnings and Precautions (5)].
In the pediatric population, there have been reports of overdosage with Fluvastatin Retard sodium in children including a 2-year-old and the other 3 years of age, either of whom may have possibly ingested Fluvastatin Retard sodium. The maximum amount of Fluvastatin Retard sodium that could have been ingested was 80 mg (4 x 20 mg capsules). Vomiting was induced by ipecac in both children and no capsules were noted in their emesis. Neither child experienced any adverse symptoms and both recovered from the incident without problems.
In the postmarketing experience there have been reports of accidental ingestion of Fluvastatin Retard tablets in infants up to 3 years of age. In one case, increased serum CPK values were noted. There have been reports of intentional overdose in adolescents with the development of hepatic enzyme elevations, convulsions and gastroenteritis/vomiting/diarrhea.
Fluvastatin Retard sodium is a water-soluble cholesterol lowering agent which acts through the inhibition of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase.
Fluvastatin Retard sodium is [R*,S*-(E)]-(±)-7-[3-(4-fluorophenyl)-1-(1-methylethyl)-1H-indol-2-yl]-3,5-dihydroxy-6-heptenoic acid, monosodium salt. Its structural formula is:
Outcome data for the Fluvastatin Retard 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 Retard 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).
In the Lipoprotein and Coronary Atherosclerosis Study (LCAS), the effect of Fluvastatin Retard 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 Retard capsules, 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, fluvasatin 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 Retard patients versus 22% of all placebo patients). A significant difference in favor of Fluvastatin Retard capsules was found between all Fluvastatin Retard 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.

What are Fluvastatin Retard capsules?
Fluvastatin Retard 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 Retard capsules are for people whose cholesterol does not come down enough with exercise and a low-fat diet alone.
Fluvastatin Retard capsules may be used in patients with heart disease (coronary artery disease) to:
Treatment with Fluvastatin Retard capsules has not been shown to prevent heart attacks or stroke.
Fluvastatin Retard capsules are taken one or two times a day.
Who should not take Fluvastatin Retard capsules?
Do not take Fluvastatin Retard capsules if you:
Fluvastatin Retard capsules have not been studied in children under 9 years of age.
Before taking Fluvastatin Retard capsules, tell your doctor if you:
