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 nonpharmacologic measures alone has been inadequate. Pravastatin Sodium is an HMG-CoA reductase inhibitor (statin) indicated as an adjunctive therapy to diet to: Reduce the risk of MI, revascularization, and cardiovascular mortality in hypercholesterolemic patients without clinically evident CHD.
(1.1) Reduce the risk of total mortality by reducing coronary death, MI, revascularization, stroke/TIA, and the progression of coronary atherosclerosis in patients with clinically evident CHD. (1.1) Reduce elevated Total-C, LDL-C, ApoB, and TG levels and to increase HDL C in patients with primary hypercholesterolemia and mixed dyslipidemia. (1.2) Reduce elevated serum TG levels in patients with hypertriglyceridemia.
(1.2) Treat patients with primary dysbetalipoproteinemia who are not responding to diet. (1.2) Treat children and adolescent patients ages 8 years and older with heterozygous familial hypercholesterolemia after failing an adequate trial of diet therapy. (1.2) Limitations of use: Pravastatin sodium has not been studied in Fredrickson Types I and V dyslipidemias. (1.3)
1.1Prevention of Cardiovascular Disease
In hypercholesterolemic patients without clinically evident coronary heart disease (CHD), Pravastatin Sodium is indicated to: reduce the risk of myocardial infarction (MI). reduce the risk of undergoing myocardial revascularization procedures. reduce the risk of cardiovascular mortality with no increase in death from non-cardiovascular causes. In patients with clinically evident CHD, Pravastatin Sodium is indicated to: reduce the risk of total mortality by reducing coronary death. reduce the risk of MI reduce the risk of undergoing myocardial revascularization procedures. reduce the risk of stroke and stroke/transient ischemic attack (TIA). slow the progression of coronary atherosclerosis.
1.2Hyperlipidemia Pravastatin
Sodium is indicated: as an adjunct to diet to reduce elevated total cholesterol (Total-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein B (ApoB), and triglyceride (TG) levels and to increase high-density lipoprotein cholesterol (HDL-C) in patients with primary hypercholesterolemia and mixed dyslipidemia ( Fredrickson Types IIa and IIb). 1 as an adjunct to diet for the treatment of patients with elevated serum TG levels ( Fredrickson Type IV). for the treatment of patients with primary dysbetalipoproteinemia ( Fredrickson Type III) who do not respond adequately to diet. as an adjunct to diet and lifestyle modification for treatment of heterozygous familial hypercholesterolemia (HeFH) in children and adolescent patients ages 8 years and older if after an adequate trial of diet the following findings are present: a.
LDL-C remains ≥190 mg/dL or b. LDL-C remains ≥160 mg/dL and: there is a positive family history of premature cardiovascular disease (CVD) or two or more other CVD risk factors are present in the patient.
1.3Limitations of Use Pravastatin
Sodium has not been studied in conditions where the major lipoprotein abnormality is elevation of chylomicrons ( Fredrickson Types I and V).
Contraindications
Hypersensitivity to any component of this medication. (4.1, 6.2, 11) Active liver disease or unexplained, persistent elevations of serum transaminases. (4.2, 5.3 ) Pregnancy (4.3, 8.1, 8.3) Lactation (4.4, 8.2)
4.1Hypersensitivity Hypersensitivity
to any component of this medication.
4.2Liver
Active liver disease or unexplained, persistent elevations of serum transaminases [see Warnings and Precautions (5.3) ].
4.3Pregnancy
Atherosclerosis is a chronic process and discontinuation of lipid-lowering drugs during pregnancy should have little impact on the outcome of long-term therapy of primary hypercholesterolemia. Cholesterol and other products of cholesterol biosynthesis are essential components for fetal development (including synthesis of steroids and cell membranes). Since statins decrease cholesterol synthesis and possibly the synthesis of other biologically active substances derived from cholesterol, they are contraindicated during pregnancy and in nursing mothers.
PRAVASTATIN 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 class of drug, therapy should be discontinued immediately and the patient apprised of the potential hazard to the fetus [see Use in Specific Populations (8.1, 8.3) ].
4.4Lactation
Pravastatin is present in human milk. Because statins have the potential for serious adverse reactions in nursing infants, women who require Pravastatin Sodium treatment should not breastfeed their infants [see Use in Specific Populations (8.2) ].
Warnings and precautions
Skeletal muscle effects (e.g., myopathy and rhabdomyolysis): predisposing factors include advanced age (≥65), uncontrolled hypothyroidism, and renal impairment. Patients should be advised to promptly report to their physician any unexplained and/or persistent muscle pain, tenderness, or weakness. Pravastatin therapy should be discontinued if myopathy is diagnosed or suspected. (5.1, 8.5) Immune-Mediated Necrotizing Myopathy (IMNM): There have been rare reports of 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 ( 5.2 ). Liver enzyme abnormalities: persistent elevations in hepatic transaminases can occur. Check liver enzyme tests before initiating therapy and as clinically indicated thereafter.
( 5.3 )
5.1Skeletal Muscle
Rare cases of rhabdomyolysis with acute renal failure secondary to myoglobinuria have been reported with pravastatin and other drugs in this class. A history of renal impairment may be a risk factor for the development of rhabdomyolysis. Such patients merit closer monitoring for skeletal muscle effects. Uncomplicated myalgia has also been reported in pravastatin-treated patients [see Adverse Reactions (6) ]. Myopathy, defined as muscle aching or muscle weakness in conjunction with increases in creatine phosphokinase (CPK) values to greater than 10 times the ULN, was rare (<0.1%) in pravastatin clinical trials.
Myopathy should be considered in any patient with diffuse myalgias, muscle tenderness or weakness, and/or marked elevation of CPK. Predisposing factors include advanced age (65), uncontrolled hypothyroidism, and renal impairment. 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 Pravastatin Sodium.
Pravastatin therapy should be discontinued if markedly elevated CPK levels occur or myopathy is diagnosed or suspected. Pravastatin 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.
The risk of myopathy during treatment with statins is increased with concurrent therapy with either erythromycin, cyclosporine, niacin, or fibrates. However, neither myopathy nor significant increases in CPK levels have been observed in 3 reports involving a total of 100 post-transplant patients (24 renal and 76 cardiac) treated for up to 2 years concurrently with pravastatin 10 to 40 mg and cyclosporine. Some of these patients also received other concomitant immunosuppressive therapies.
Further, in clinical trials involving small numbers of patients who were treated concurrently with pravastatin and niacin, there were no reports of myopathy. Also, myopathy was not reported in a trial of combination pravastatin (40 mg/day) and gemfibrozil (1200 mg/day), although 4 of 75 patients on the combination showed marked CPK elevations versus 1 of 73 patients receiving placebo. There was a trend toward more frequent CPK elevations and patient withdrawals due to musculoskeletal symptoms in the group receiving combined treatment as compared with the groups receiving placebo, gemfibrozil, or pravastatin monotherapy.
The use of fibrates alone may occasionally be associated with myopathy. The benefit of further alterations in lipid levels by the combined use of Pravastatin Sodium with fibrates should be carefully weighed against the potential risks of this combination. Cases of myopathy, including rhabdomyolysis, have been reported with pravastatin coadministered with colchicine, and caution should be exercised when prescribing pravastatin with colchicine [see Drug Interactions (7.3) ].
5.2Immune-Mediated Necrotizing Myopathy
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. Additional neuromuscular and serologic testing may be necessary.
Treatment with immunosuppressive agents may be required. Consider risk of IMNM carefully prior to initiation of a different statin. If therapy is initiated with a different statin, monitor for signs and symptoms of IMNM.
5.3Liver
Statins, like some other lipid-lowering therapies, have been associated with biochemical abnormalities of liver function. In 3 long-term (4.8-5.9 years), placebo-controlled clinical trials (WOS, LIPID, CARE), 19,592 subjects (19,768 randomized) were exposed to pravastatin or placebo [see Clinical Studies (14) ]. In an analysis of serum transaminase values (ALT, AST), incidences of marked abnormalities were compared between the pravastatin and placebo treatment groups; a marked abnormality was defined as a post-treatment test value greater than 3 times the ULN for subjects with pretreatment values less than or equal to the ULN, or 4 times the pretreatment value for subjects with pretreatment values greater than the ULN but less than 1.5 times the ULN.
Marked abnormalities of ALT or AST occurred with similar low frequency (≤1.2%) in both treatment groups. Overall, clinical trial experience showed that liver function test abnormalities observed during pravastatin therapy were usually asymptomatic, not associated with cholestasis, and did not appear to be related to treatment duration. In a 320patient placebo-controlled clinical trial, subjects with chronic (>6 months) stable liver disease, due primarily to hepatitis C or non-alcoholic fatty liver disease, were treated with 80 mg pravastatin or placebo for up to 9 months.
The primary safety endpoint was the proportion of subjects with at least one ALT ≥2 times the ULN for those with normal ALT (≤ ULN) at baseline or a doubling of the baseline ALT for those with elevated ALT (> ULN) at baseline. By Week 36, 12 out of 160 (7.5%) subjects treated with pravastatin met the prespecified safety ALT endpoint compared to 20 out of 160 (12.5%) subjects receiving placebo. Conclusions regarding liver safety are limited since the study was not large enough to establish similarity between groups (with 95% confidence) in the rates of ALT elevation.
It is recommended that liver function tests be performed prior to the initiation of therapy and when clinically indicated. Active liver disease or unexplained persistent transaminase elevations are contraindications to the use of pravastatin [see Contraindications (4.2) ]. Caution should be exercised when pravastatin is administered to patients who have a recent (<6 months) history of liver disease, have signs that may suggest liver disease (e.g., unexplained aminotransferase elevations, jaundice), or are heavy users of alcohol.
There have been rare postmarketing reports of fatal and non-fatal hepatic failure in patients taking statins, including pravastatin. If serious liver injury with clinical symptoms and/or hyperbilirubinemia or jaundice occurs during treatment with Pravastatin Sodium, promptly interrupt therapy. If an alternate etiology is not found do not restart Pravastatin Sodium.
5.4Endocrine Function
Statins interfere with cholesterol synthesis and lower circulating cholesterol levels and, as such, might theoretically blunt adrenal or gonadal steroid hormone production. Results of clinical trials with pravastatin in males and pos

Interactions
For the concurrent therapy of either cyclosporine, fibrates, niacin (nicotinic acid), or erythromycin, the risk of myopathy increases [see Warnings and Precautions (5.1) and Clinical Pharmacology (12.3) ]. Concomitant lipid-lowering therapies: use with fibrates or lipid-modifying doses (≥1 g/day) of niacin increases the risk of adverse skeletal muscle effects. Caution should be used when prescribing with Pravastatin Sodium.
(7) Cyclosporine: combination increases exposure. Limit pravastatin to 20 mg once daily. (2.6, 7.1) Clarithromycin: combination increases exposure. Limit pravastatin to 40 mg once daily. (2.7, 7.2)
7.1Cyclosporine
The risk of myopathy/rhabdomyolysis is increased with concomitant administration of cyclosporine. Limit pravastatin to 20 mg once daily for concomitant use with cyclosporine [see Dosage and Administration (2.6) , Warnings and Precautions (5.1) , and Clinical Pharmacology (12.3) ].
7.2Clarithromycin and Other Macrolide Antibiotics
The risk of myopathy/rhabdomyolysis is increased with concomitant administration of clarithromycin. Limit pravastatin to 40 mg once daily for concomitant use with clarithromycin [see Dosage and Administration (2.7) , Warnings and Precautions (5.1) , and Clinical Pharmacology (12.3) ]. Other macrolides (e.g., erythromycin and azithromycin) have the potential to increase statin exposures while used in combination. Pravastatin should be used cautiously with macrolide antibiotics due to a potential increased risk of myopathies.
7.3Colchicine
The risk of myopathy/rhabdomyolysis is increased with concomitant administration of colchicine [see Warnings and Precautions (5.1) ].
7.4 Gemfibrozil Due to an increased risk of myopathy/rhabdomyolysis when HMG-CoA reductase inhibitors are coadministered with gemfibrozil, concomitant administration of Pravastatin Sodium with gemfibrozil should be avoided [see Warnings and Precautions (5.1) ].
7.5Other 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, Pravastatin Sodium should be administered with caution when used concomitantly with other fibrates [see Warnings and Precautions (5.1) ].
7.6Niacin
The risk of skeletal muscle effects may be enhanced when pravastatin is used in combination with niacin; a reduction in Pravastatin Sodium dosage should be considered in this setting [see Warnings and Precautions (5.1) ].
Pregnancy and breastfeeding
8.1Pregnancy Risk Summary Pravastatin
Sodium is contraindicated for use in pregnant woman because of the potential for fetal harm. As safety in pregnant women has not been established and there is no apparent benefit to therapy with Pravastatin Sodium during pregnancy, Pravastatin Sodium should be immediately discontinued as soon as pregnancy is recognized [see Contraindications (4.3) ]. Limited published data on the use of Pravastatin Sodium in pregnant women are insufficient to determine a drug-associated risk of major congenital malformations or miscarriage.
In animal reproduction studies, no evidence of fetal malformations was seen in rabbits or rats exposed to 10 times to 120 times, respectively, the maximum recommended human dose (MRHD) of 80 mg/day. Fetal skeletal abnormalities, offspring mortality, and developmental delays occurred when pregnant rats were administered 10 times to 12 times the MRHD during organogenesis to parturition [see Data ]. Advise pregnant women of the potential risk to a fetus.
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 2-4% and 15-20%, respectively. Data Human Data Limited published data on pravastatin have not shown an increased risk of major congenital malformations or miscarriage. Rare reports of congenital anomalies have been received following intrauterine exposure to other statins.
In a review 2 of approximately 100 prospectively followed pregnancies in women exposed to simvastatin or lovastatin, the incidences of congenital anomalies, spontaneous abortions, and fetal deaths/stillbirths did not exceed what would be expected in the general population. The number of cases is adequate to exclude a ≥3 to 4-fold increase in congenital anomalies over the background incidence. In 89% of the prospectively followed pregnancies, drug treatment was initiated prior to pregnancy and was discontinued at some point in the first trimester when pregnancy was identified.
Animal Data Embryofetal and neonatal mortality was observed in rats given pravastatin during the period of organogenesis or during organogenesis continuing through weaning. In pregnant rats given oral gavage doses of 4, 20, 100, 500, and 1000 mg/kg/day from gestation days 7 through 17 (organogenesis) increased mortality of offspring and increased cervical rib skeletal anomalies were observed at ≥100 mg/kg/day systemic exposure, 10 times the human exposure at 80 mg/day MRHD based on body surface area (mg/m 2 ).
In other studies, no teratogenic effects were observed when pravastatin was dosed orally during organogenesis in rabbits (gestation days 6 through 18) up to 50 mg/kg/day or in rats (gestation days 7 through 17) up to 1000 mg/kg/day. Exposures were 10 times (rabbit) or 120 times (rat) the human exposure at 80 mg/day MRHD based on body surface area (mg/m 2 ). In pregnant rats given oral gavage doses of 10, 100, and 1000 mg/kg/day from gestation day 17 through lactation day 21 (weaning), increased mortality of offspring and developmental delays were observed at ≥100 mg/kg/day systemic exposure, corresponding to 12 times the human exposure at 80 mg/day MRHD, based on body surface area (mg/m 2 ).
In pregnant rats, pravastatin crosses the placenta and is found in fetal tissue at 30% of the maternal plasma levels following administration of a single dose of 20 mg/day orally on gestation day 18, which corresponds to exposure 2 times the MRHD of 80 mg daily based on body surface area (mg/m 2 ). In lactating rats, up to 7 times higher levels of pravastatin are present in the breast milk than in the maternal plasma, which corresponds to exposure 2 times the MRHD of 80 mg/day based on body surface area (mg/m 2 ).
8.2Lactation Risk Summary
Pravastatin use is contraindicated during breastfeeding [see Contraindications (4.4) ]. Based on one lactation study in published literature, pravastatin is present in human milk. There is no available information on the effects of the drug on the breastfed infant or the effects of the drug on milk production. Because of the potential for serious adverse reactions in a breastfed infant, advise patients that breastfeeding is not recommended during treatment with Pravastatin Sodium.
8.3Females and Males of Reproductive Potential Contraception Females Pravastatin
Sodium may cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1) ]. Advise females of reproductive potential to use effective contraception during treatment with Pravastatin Sodium.
Adverse reactions
Pravastatin is generally well tolerated; adverse reactions have usually been mild and transient. In 4-month-long placebo-controlled trials, 1.7% of pravastatin-treated patients and 1.2% of placebo-treated patients were discontinued from treatment because of adverse experiences attributed to study drug therapy; this difference was not statistically significant. In short-term clinical trials, the most commonly reported adverse reactions (≥2% and > placebo) regardless of causality were: musculoskeletal pain, nausea/vomiting, upper respiratory infection, diarrhea, and headache.

6.1Adverse Clinical Events Short-Term Controlled Trials In the Pravastatin
Sodium placebo-controlled clinical trials database of 1313 patients (age range 20-76 years, 32.4% women, 93.5% Caucasians, 5% Blacks, 0.9% Hispanics, 0.4% Asians, 0.2% Others) with a median treatment duration of 14 weeks, 3.3% of patients on Pravastatin Sodium and 1.2% patients on placebo discontinued due to adverse events regardless of causality. The most common adverse reactions that led to treatment discontinuation and occurred at an incidence greater than placebo were: liver function test increased, nausea, anxiety/depression, and dizziness.
All adverse clinical events (regardless of causality) reported in ≥2% of pravastatin-treated patients in placebo-controlled trials of up to 8 months duration are identified in Table 1: Table 1: Adverse Events in ≥2% of Patients Treated with Pravastatin 5 to 40 mg and at an Incidence Greater Than Placebo in Short-Term Placebo-Controlled Trials (% of patients) Body System/Event 5 mg N=100 10 mg N=153 20 mg N=478 40 mg N=171 Any Dose N=902 Placebo N=411 Cardiovascular Angina Pectoris 5.0 4.6 4.8 3.5 4.5
3.6 The safety and tolerability of Pravastatin Sodium at a dose of 80 mg in 2 controlled trials with a mean exposure of 8.6 months was similar to that of Pravastatin Sodium at lower doses except that 4 out of 464 patients taking 80 mg of pravastatin had a single elevation of CK >10 times ULN compared to 0 out of 115 patients taking 40 mg of pravastatin. Long-Term Controlled Morbidity and Mortality Trials In the Pravastatin Sodium placebo-controlled clinical trials database of 21,483 patients (age range 24-75 years, 10.3% women, 52.3% Caucasians, 0.8% Blacks, 0.5% Hispanics, 0.1% Asians, 0.1% Others, 46.1% Not Recorded) with a median treatment duration of 261 weeks, 8.1% of patients on Pravastatin Sodium and 9.3% patients on placebo discontinued due to adverse events regardless of causality.
Adverse event data were pooled from 7 double-blind, placebo-controlled trials (West of Scotland Coronary Prevention Study [WOS]; Cholesterol and Recurrent Events study [CARE]; Long-term Intervention with Pravastatin in Ischemic Disease study [LIPID]; Pravastatin Limitation of Atherosclerosis in the Coronary Arteries study [PLAC I]; Pravastatin, Lipids and Atherosclerosis in the Carotids study [PLAC II]; Regression Growth Evaluation Statin Study [REGRESS]; and Kuopio Atherosclerosis Prevention Study [KAPS]) involving a total of 10,764 patients treated with pravastatin 40 mg and 10,719 patients treated with placebo.
The safety and tolerability profile in the pravastatin group was comparable to that of the placebo group. Patients were exposed to pravastatin for a mean of 4.0 to 5.1 years in WOS, CARE, and LIPID and 1.9 to 2.9 years in PLAC I, PLAC II, KAPS, and REGRESS. In these long-term trials, the most common reasons for discontinuation were mild, non-specific gastrointestinal complaints. Collectively, these 7 trials represent 47,613 patient-years of exposure to pravastatin.
All clinical adverse events (regardless of causality) occurring in ≥2% of patients treated with pravastatin in these studies are identified in Table 2. Table 2: Adverse Events in ≥2% of Patients Treated with Pravastatin 40 mg and at an Incidence Greater Than Placebo in Long-Term Placebo- Controlled Trials Body System/Event Pravastatin (N=10,764) % of patients Placebo (N=10,719) % of patients Dermatologic Rash (including dermatitis) 7.2

2.9 In addition to the events listed above in the long-term trials table, events of probable, possible, or uncertain relationship to study drug that occurred in <2.0% of pravastatin-treated patients in the long-term trials included the following: Dermatologic: scalp hair abnormality (including alopecia), urticaria. Endocrine/Metabolic: sexual dysfunction, libido change. General: flushing. Immunologic: allergy, edema head/neck.
In addition to the events reported above, as with other drugs in this class, the following events have been reported during postmarketing experience with Pravastatin Sodium, regardless of causality assessment: Musculoskeletal: myopathy, rhabdomyolysis, tendon disorder, polymyositis. There have been rare reports of immune-mediated necrotizing myopathy associated with statin use [see Warnings and Precautions ( 5.2 ) ].
Nervous System: dysfunction of certain cranial nerves (including alteration of taste, impairment of extraocular movement, facial paresis), 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).
