PRAVASTATIN: 8,284 Adverse Event Reports & Safety Profile

Pravastatin sodium, USP is one of a class of lipid-lowering compounds, the statins, which reduce cholesterol biosynthesis. These agents are competitive inhibitors of HMG-CoA reductase, the enzyme catalyzing the early rate-limiting step in cholesterol biosynthesis, conversion of HMG-CoA to mevalonate. Pravastatin sodium, USP is designated chemically as 1-naphthaleneheptanoic acid, 1,2,6,7,8,8a-hexahydro-β,δ,6-trihydroxy-2-methyl-8-(2-methyl-1-oxobutoxy)-, monosodium salt, [1 S -[1α (β S *,δ S *),2α,6α,8β( R *),8aα]]-. It has the following structural formula: C 23 H 35 NaO 7 M.W.

Chemical

Structure

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 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)

AND ADMINISTRATION Adults: the recommended starting dose is 40 mg once daily.

Use

80 mg dose only for patients not reaching LDL-C goal with 40 mg. (2.2) Significant renal impairment: the recommended starting dose is pravastatin 10 mg once daily. (2.3) Children (ages 8 to 13 years, inclusive): the recommended starting dose is 20 mg once daily. (2.4) Adolescents (ages 14 to 18 years): the recommended starting dose is 40 mg once daily. (2.4)

2.1 General Dosing Information The patient should be placed on a standard cholesterol-lowering diet before receiving Pravastatin Sodium and should continue on this diet during treatment with Pravastatin Sodium <span class="opacity-50 text-xs">[see NCEP Treatment Guidelines for details on dietary therapy]</span>.

2.2 Adult Patients The recommended starting dose is 40 mg once daily. If a daily dose of 40 mg does not achieve desired cholesterol levels, 80 mg once daily is recommended.

Pravastatin

Sodium can be administered orally as a single dose at any time of the day, with or without food. 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.

2.3 Patients with Renal Impairment In patients with severe renal impairment, a starting dose of 10 mg pravastatin daily is recommended.

2.4 Pediatric Patients Children (Ages 8 to 13 Years, Inclusive) The recommended dose is 20 mg once daily in children 8 to 13 years of age. Doses greater than 20 mg have not been studied in this patient population. Adolescents (Ages 14 to 18 Years) The recommended starting dose is 40 mg once daily in adolescents 14 to 18 years of age. Doses greater than 40 mg have not been studied in this patient population. Children and adolescents treated with pravastatin should be reevaluated in adulthood and appropriate changes made to their cholesterol-lowering regimen to achieve adult goals for LDL-C <span class="opacity-50 text-xs">[see Indications and Usage (1.2) ]</span>.

2.5 Concomitant Lipid-Altering Therapy Pravastatin Sodium may be used with bile acid resins. When administering a bile-acid-binding resin (e.g., cholestyramine, colestipol) and pravastatin, Pravastatin Sodium should be given either 1 hour or more before or at least 4 hours following the resin. [See Clinical Pharmacology (12.3) ]

2.6 Dosage in Patients Taking Cyclosporine In patients taking immunosuppressive drugs such as cyclosporine concomitantly with pravastatin, therapy should begin with 10 mg of pravastatin sodium once-a-day at bedtime and titration to higher doses should be done with caution. Most patients treated with this combination received a maximum pravastatin sodium dose of 20 mg/day. In patients taking cyclosporine, therapy should be limited to 20 mg of pravastatin sodium once daily <span class="opacity-50 text-xs">[see Warnings and Precautions (5.1) and Drug Interactions (7.1) ]</span>.

4.1 Hypersensitivity Hypersensitivity to any component of this medication.

4.2 Liver Active liver disease or unexplained, persistent elevations of serum transaminases <span class="opacity-50 text-xs">[see Warnings and Precautions (5.3) ]</span>.

4.3 Pregnancy 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 <span class="opacity-50 text-xs">[see Use in Specific Populations (8.1, 8.3) ]</span>.

4.4 Lactation 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 <span class="opacity-50 text-xs">[see Use in Specific Populations (8.2) ]</span>.

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.

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 &gt;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.

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 &lt;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. Musculoskeletal: muscle weakness.

Nervous

System: vertigo, insomnia, memory impairment, neuropathy (including peripheral neuropathy).

Special

Senses: taste disturbance.

6.2 Postmarketing Experience 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 <span class="opacity-50 text-xs">[see Warnings and Precautions ( 5.2 ) ]</span>.

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). Hypersensitivity: anaphylaxis, angioedema, lupus erythematosus-like syndrome, polymyalgia rheumatica, dermatomyositis, vasculitis, purpura, hemolytic anemia, positive ANA, ESR increase, arthritis, arthralgia, asthenia, photosensitivity, chills, malaise, toxic epidermal necrolysis, erythema multiforme (including Stevens-Johnson syndrome). Gastrointestinal: abdominal pain, constipation, pancreatitis, hepatitis (including chronic active hepatitis), cholestatic jaundice, fatty change in liver, cirrhosis, fulminant hepatic necrosis, hepatoma, fatal and non-fatal hepatic failure. Dermatologic: a variety of skin changes (e.g., nodules, discoloration, dryness of mucous membranes, changes to hair/nails). Renal: urinary abnormality (including dysuria, frequency, nocturia). Respiratory: dyspnea, interstitial lung disease. Psychiatric: nightmare. Reproductive: gynecomastia.

Laboratory

Abnormalities: liver function test abnormalities, thyroid function abnormalities.

6.3 Laboratory Test Abnormalities Increases in ALT, AST values and CPK have been observed <span class="opacity-50 text-xs">[see Warnings and Precautions (5.1 , 5.3 ) ]</span>. Transient, asymptomatic eosinophilia has been reported. Eosinophil counts usually returned to normal despite continued therapy. Anemia, thrombocytopenia, and leukopenia have been reported with statins

6.4 Pediatric Patients In a 2-year, double-blind, placebo-controlled study involving 100 boys and 114 girls with HeFH (n=214; age range 8-18.5 years, 53% female, 95% Caucasians, &lt;1% Blacks, 3% Asians, 1% Other), the safety and tolerability profile of pravastatin was generally similar to that of placebo. [See Warnings and Precautions (5.4) , Use in Specific Populations (8.4) , and Clinical Pharmacology (12.3) . ]

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 )

5.1 Skeletal 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 <span class="opacity-50 text-xs">[see Adverse Reactions (6) ]</span>. 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 (&lt;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 <span class="opacity-50 text-xs">[see Drug Interactions (7.3) ]</span>.

5.2 Immune-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.

5.3 Liver 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.

5.4 Endocrine 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 post-menopausal females were inconsistent with regard to possible effects of the drug on basal steroid hormone levels. In a study of 21 males, the mean testosterone response to human chorionic gonadotropin was significantly reduced (p&lt;0.004) after 16 weeks of treatment with 40 mg of pravastatin. However, the percentage of patients showing a ≥50% rise in plasma testosterone after human chorionic gonadotropin stimulation did not change significantly after therapy in these patients. The effects of statins on spermatogenesis and fertility have not been studied in adequate numbers of patients. The effects, if any, of pravastatin on the pituitary- gonadal axis in pre-menopausal females are unknown. Patients treated with pravastatin who display clinical evidence of endocrine dysfunction should be evaluated appropriately. Caution should also be exercised if a statin or other agent used to lower cholesterol levels is administered to patients also receiving other drugs (e.g., ketoconazole, spironolactone, cimetidine) that may diminish the levels or activity of steroid hormones. In a placebo-controlled study of 214 pediatric patients with HeFH, of which 106 were treated with pravastatin (20 mg in the children aged 8-13 years and 40 mg in the adolescents aged 14-18 years) for 2 years, there were no detectable differences seen in any of the endocrine parameters (ACTH, cortisol, DHEAS, FSH, LH, TSH, estradiol [girls] or testosterone [boys]) relative to placebo. There were no detectable differences seen in height and weight changes, testicular volume changes, or Tanner score relative to placebo.

There were no detectable differences seen in height and weight changes, testicular volume changes, or Tanner score relative to placebo.

PRECAUTIONS General Pravastatin sodium may elevate creatine phosphokinase and transaminase levels (see ADVERSE REACTIONS ). This should be considered in the differential diagnosis of chest pain in a patient on therapy with pravastatin.

Homozygous Familial

Hypercholesterolemia. Pravastatin has not been evaluated in patients with rare homozygous familial hypercholesterolemia. In this group of patients, it has been reported that HMG-CoA reductase inhibitors are less effective because the patients lack functional LDL receptors.

Renal

Insufficiency. A single 20 mg oral dose of pravastatin was administered to 24 patients with varying degrees of renal impairment (as determined by creatinine clearance). No effect was observed on the pharmacokinetics of pravastatin or its 3α-hydroxy isomeric metabolite (SQ 31,906). A small increase was seen in mean AUC values and half-life (t ½ ) for the inactive enzymatic ring hydroxylation metabolite (SQ 31,945). Given this small sample size, the dosage administered, and the degree of individual variability, patients with renal impairment who are receiving pravastatin should be closely monitored. Information for Patients Patients should be advised to report promptly unexplained muscle pain, tenderness or weakness, particularly if accompanied by malaise or fever (see WARNINGS: Skeletal Muscle ).

Drug Interactions Immunosuppressive

Drugs, Gemfibrozil, Niacin (Nicotinic Acid), Erythromycin: See WARNINGS: Skeletal Muscle . Cytochrome P450 3A4 Inhibitors: In vitro and in vivo data indicate that pravastatin is not metabolized by cytochrome P450 3A4 to a clinically significant extent. This has been shown in studies with known cytochrome P450 3A4 inhibitors (see Diltiazem and Itraconazole below). Other examples of cytochrome P450 3A4 inhibitors include ketoconazole, mibefradil, and erythromycin. Diltiazem: Steady-state levels of diltiazem (a known, weak inhibitor of P450 3A4) had no effect on the pharmacokinetics of pravastatin. In this study, the AUC and C max of another HMG-CoA reductase inhibitor which is known to be metabolized by cytochrome P450 3A4 increased by factors of 3.6 and 4.3, respectively. Itraconazole: The mean AUC and C max for pravastatin were increased by factors of 1.7 and 2.5, respectively, when given with itraconazole (a potent P450 3A4 inhibitor which also inhibits p-glycoprotein transport) as compared to placebo. The mean t ½ was not affected by itraconazole, suggesting that the relatively small increases in C max and AUC were due solely to increased bioavailability rather than a decrease in clearance, consistent with inhibition of p-glycoprotein transport by itraconazole. This drug transport system is thought to affect bioavailability and excretion of HMG-CoA reductase inhibitors, including pravastatin. The AUC and C max of another HMG-CoA reductase inhibitor which is known to be metabolized by cytochrome P450 3A4 increased by factors of 19 and 17, respectively, when given with itraconazole. Antipyrine: Since concomitant administration of pravastatin had no effect on the clearance of antipyrine, interactions with other drugs metabolized via the same hepatic cytochrome isozymes are not expected. Cholestyramine/Colestipol: Concomitant administration resulted in an approximately 40 to 50% decrease in the mean AUC of pravastatin. However, when pravastatin was administered 1 hour before or 4 hours after cholestyramine or 1 hour before colestipol and a standard meal, there was no clinically significant decrease in bioavailability or therapeutic effect. (See DOSAGE AND ADMINISTRATION: Concomitant Therapy .) Warfarin: Concomitant administration of 40 mg pravastatin had no clinically significant effect on prothrombin time when administered in a study to normal elderly subjects who were stabilized on warfarin. Cimetidine: The AUC 0-12 hr for pravastatin when given with cimetidine was not significantly different from the AUC for pravastatin when given alone. A significant difference was observed between the AUC's for pravastatin when given with cimetidine compared to when administered with antacid. Digoxin: In a crossover trial involving 18 healthy male subjects given 20 mg pravastatin and 0.2 mg digoxin concurrently for 9 days, the bioavailability parameters of digoxin were not affected. The AUC of pravastatin tended to increase, but the overall bioavailability of pravastatin plus its metabolites SQ 31,906 and SQ 31,945 was not altered. Cyclosporine: Some investigators have measured cyclosporine levels in patients on pravastatin (up to 20 mg), and to date, these results indicate no clinically meaningful elevations in cyclosporine levels. In one single-dose study, pravastatin levels were found to be increased in cardiac transplant patients receiving cyclosporine. Gemfibrozil: In a crossover study in 20 healthy male volunteers given concomitant single doses of pravastatin and gemfibrozil, there was a significant decrease in urinary excretion and protein binding of pravastatin. In addition, there was a significant increase in AUC, C max , and T max for the pravastatin metabolite SQ 31,906. Combination therapy with pravastatin and gemfibrozil is generally not recommended. (See WARNINGS: Skeletal Muscle .) In interaction studies with aspirin , antacids (1 hour prior to pravastatin sodium), cimetidine, nicotinic acid, or probucol, no statistically significant differences in bioavailability were seen when pravastatin sodium was administered.

Endocrine

Function HMG-CoA reductase inhibitors 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 post-menopausal females were inconsistent with regard to possible effects of the drug on basal steroid hormone levels. In a study of 21 males, the mean testosterone response to human chorionic gonadotropin was significantly reduced (p<0.004) after 16 weeks of treatment with 40 mg of pravastatin. However, the percentage of patients showing a ≥50% rise in plasma testosterone after human chorionic gonadotropin stimulation did not change significantly after therapy in these patients. The effects of HMG-CoA reductase inhibitors on spermatogenesis and fertility have not been studied in adequate numbers of patients. The effects, if any, of pravastatin on the pituitary-gonadal axis in pre-menopausal females are unknown. Patients treated with pravastatin who display clinical evidence of endocrine dysfunction should be evaluated appropriately. Caution should also be exercised if an HMG-CoA reductase inhibitor or other agent used to lower cholesterol levels is administered to patients also receiving other drugs (e.g., ketoconazole, spironolactone, cimetidine) that may diminish the levels or activity of steroid hormones. In a placebo-controlled study of 214 pediatric patients with HeFH, of which 106 were treated with pravastatin (20 mg in the children aged 8-13 years and 40 mg in the adolescents aged 14-18 years) for two years, there were no detectable differences seen in any of the endocrine parameters [ACTH, cortisol, DHEAS, FSH, LH, TSH, estradiol (girls) or testosterone (boys)] relative to placebo. There were no detectable differences seen in height and weight changes, testicular volume changes, or Tanner score relative to placebo.

Cns

Toxicity CNS vascular lesions, characterized by perivascular hemorrhage and edema and mononuclear cell infiltration of perivascular spaces, were seen in dogs treated with pravastatin at a dose of 25 mg/kg/day. These effects in dogs were observed at approximately 59 times the human dose of 80 mg/day, based on AUC. Similar CNS vascular lesions have been observed with several other drugs in this class. A chemically similar drug in this class produced optic nerve degeneration (Wallerian degeneration of retinogeniculate fibers) in clinically normal dogs in a dose-dependent fashion starting at 60 mg/kg/day, a dose that produced mean plasma drug levels about 30 times higher than the mean drug level in humans taking the highest recommended dose (as measured by total enzyme inhibitory activity). This same drug also produced vestibulocochlear Wallerian-like degeneration and retinal ganglion cell chromatolysis in dogs treated for 14 weeks at 180 mg/kg/day, a dose which resulted in a mean plasma drug level similar to that seen with the 60 mg/kg/day dose. Carcinogenesis, Mutagenesis, Impairment of Fertility In a 2-year study in rats fed pravastatin at doses of 10, 30, or 100 mg/kg body weight, there was an increased incidence of hepatocellular carcinomas in males at the highest dose (p<0.01). These effects in rats were observed at approximately 12 times the human dose (HD) of 80 mg based on body surface area mg/m 2 and at approximately 4 times the human dose, based on AUC. In a 2-year study in mice fed pravastatin at doses of 250 and 500 mg/kg/day, there was an increased incidence of hepatocellular carcinomas in males and females at both 250 and 500 mg/kg/day (p<0.0001). At these doses, lung adenomas in females were increased (p=0.013). These effects in mice were observed at approximately 15 times (250 mg/kg/day) and 23 times (500 mg/kg/day) the human dose of 80 mg, based on AUC. In another 2-year study in mice with doses up to 100 mg/kg/day (producing drug exposures approximately 2 times the human dose of 80 mg, based on AUC), there were no drug-induced tumors. 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 ; a forward mutation assay in L5178Y TK +/- mouse lymphoma cells; a chromosomal aberration test in hamster cells; and a gene conversion assay using Saccharomyces cerevisiae . In addition, there was no evidence of mutagenicity in either a dominant lethal test in mice or a micronucleus test in mice. In a study in rats, with daily doses up to 500 mg/kg, pravastatin did not produce any adverse effects on fertility or general reproductive performance. However, in a study with another HMG-CoA reductase inhibitor, there was decreased fertility in male rats treated for 34 weeks at 25 mg/kg body weight, although this effect was not observed in a subsequent fertility study when this same dose was administered for 11 weeks (the entire cycle of spermatogenesis, including epididymal maturation). In rats treated with this same reductase inhibitor at 180 mg/kg/day, seminiferous tubule degeneration (necrosis and loss of spermatogenic epithelium) was observed. Although not seen with pravastatin, two similar drugs in this class caused drug-related testicular atrophy, decreased spermatogenesis, spermatocytic degeneration, and giant cell formation in dogs. The clinical significance of these findings is unclear.

Pregnancy Pregnancy

Category X. See CONTRAINDICATIONS . Safety in pregnant women has not been established. Pravastatin was not teratogenic in rats at doses up to 1000 mg/kg daily or in rabbits at doses of up to 50 mg/kg daily. These doses resulted in 10X (rabbit) or 120X (rat) the human exposure based on surface area (mg/meter 2 ). Rare reports of congenital anomalies have been received following intrauterine exposure to other HMG-CoA reductase inhibitors. In a review 7 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 only to exclude a three-to-four-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. As safety in pregnant women has not been established and there is no apparent benefit to therapy with pravastatin sodium during pregnancy (see CONTRAINDICATIONS ), treatment should be immediately discontinued as soon as pregnancy is recognized. Pravastatin 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.

Nursing

Mothers A small amount of pravastatin is excreted in human breast milk. Because of the potential for serious adverse reactions in nursing infants, women taking pravastatin sodium should not nurse (see CONTRAINDICATIONS ).

Pediatric Use

The safety and effectiveness of pravastatin sodium in children and adolescents from 8-18 years of age have been evaluated in a placebo-controlled study of 2 years duration. Patients treated with pravastatin had an adverse experience profile generally similar to that of patients treated with placebo with influenza and headache commonly reported in both treatment groups. (See ADVERSE REACTIONS: Pediatric Patients .) Doses greater than 40 mg have not been studied in this population. Children and adolescent females of childbearing potential should be counseled on appropriate contraceptive methods while on pravastatin therapy (see CONTRAINDICATIONS and PRECAUTIONS: Pregnancy ). For dosing information see DOSAGE AND ADMINISTRATION: Adult Patients and Pediatric Patients . Double-blind, placebo-controlled pravastatin studies in children less than 8 years of age have not been conducted.

Geriatric Use

The beneficial effect of pravastatin in elderly subjects in reducing cardiovascular events and in modifying lipid profiles was similar to that seen in younger subjects. The adverse event profile in the elderly was similar to that in the overall population. Other reported clinical experience has not identified differences in responses to pravastatin between elderly and younger patients. Mean pravastatin AUCs are slightly (25-50%) higher in elderly subjects than in healthy young subjects, but mean C max , T max and t ½ values are similar in both age groups and substantial accumulation of pravastatin would not be expected in the elderly (see CLINICAL PHARMACOLOGY: Pharmacokinetics/Metabolism ).

INTERACTIONS

• See full prescribing information for details regarding concomitant use of pravastatin sodium with other drugs that increase the risk of myopathy and rhabdomyolysis. ( 2.5 , 7.1 )
• Bile Acid Sequestrants: in patients taking a bile acid sequestrant, administer pravastatin sodium at least 1 hour before or at least 4 hours after the bile acid sequestrant ( 7.2 )

7.1 Drug Interactions that Increase the Risk of Myopathy and Rhabdomyolysis with Pravastatin Sodium Pravastatin sodium is a substrate of the transport protein OATP1B1. Pravastatin sodium plasma levels can be significantly increased with concomitant administration of inhibitors of OATP1B1.

Table

3 includes a list of drugs that increase the risk of myopathy and rhabdomyolysis when used concomitantly with pravastatin sodium and instructions for preventing or managing them [see Warnings and Precautions ( 5.1 ) and Clinical Pharmacology ( 12.3 )].

Table

3: Drug Interactions that Increase the Risk of Myopathy and Rhabdomyolysis with Pravastatin Sodium Gemfibrozil Clinical Impact: There is an increased risk of myopathy/rhabdomyolysis when pravastatin Sodium is administered with gemfibrozil Intervention: Avoid concomitant use of gemfibrozil with pravastatin sodium.

Cyclosporine Clinical

Impact: The risk of myopathy and rhabdomyolysis is increased with concomitant use of cyclosporine with pravastatin sodium. Intervention: Initiate with a dosage of pravastatin sodium 10 mg once daily. Do not exceed pravastatin sodium 20 mg once daily [see Dosage and Administration ( Error! Hyperlink reference not valid. )].

Select Macrolide Antibiotics Clinical

Impact: The risk of myopathy and rhabdomyolysis is increased by concomitant use of clarithromycin or erythromycin with pravastatin sodium. Other macrolides (e.g., azithromycin) have the potential to increase pravastatin sodium exposures and increase the risk of myopathy and rhabdomyolysis when used concomintantly. Intervention: For patients taking erythromycin or clarithromycin, do not exceed 40 mg pravastatin sodium once daily [see Dosage and Administration ( Error! Hyperlink reference not valid. )].

Niacin Clinical

Impact: Cases of myopathy and rhabdomyolysis have been observed with concomitant use of niacin with pravastatin sodium. Intervention: Consider if the benefit of using niacin concomitantly with pravastatin sodium 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 of either drug. Fibrates (other than Gemfibrozil)

Clinical

Impact: Fibrates may cause myopathy when given alone. The risk of myopathy and rhabdomyolysis is increased with concomitant use of fibrates with pravastatin sodium. Intervention: Consider if the benefit of using fibrates concomitantly with pravastatin sodium 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 of either drug.

Colchicine Clinical

Impact: Cases of myopathy and rhabdomyolysis have been reported with concomitant use of colchicine with pravastatin sodium. Intervention: Consider if the benefit of using colchicine concomitantly with pravastatin sodium 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 of either drug.

7.2 Drug Interactions that Decrease the Efficacy of Pravastatin Sodium Table 4 presents drug interactions that may decrease the efficacy of pravastatin sodium and instructions for preventing or managing them.
