Primary and secondary prevention of atheroschlerotic cardiovascular disease (ASCVD)
ACC/AHA Cholesterol Guideline Recommendations (2013) for adults ≥21 years
Primary prevention
- LDL-C ≥190 mg/dL: High-intensity therapy agent atorvastatin or rosuvastatin recommended
- Type 1 or 2 diabetes (40-75 years of age): Moderate-intensity therapy: 20-40 mg simvastatin PO qDay
- Type 1 or 2 diabetes (40-75 years of age and 10 year estimated risk of ASCVD ≥7.5%): High-intensity therapy agent atorvastatin or rosuvastatin recommended
- 40-75 years of age and 10 year estimated risk of ASCVD ≥7.5% : Moderate-intensity therapy: 20-40 mg simvastatin PO qDay; may consider high-intensity therapy agent atorvastatin or rosuvastatin
Secondary prevention
- Presence of ASCVD, including stroke/TIA or peripheral arterial disease believed to be of atherosclerotic origin or post-CABG
- ≤75 years: Treat with high-intensity therapy agent atorvastatin or rosuvastatin
- >75 years: Administer 20-40 mg simvastatin PO qDay (moderate-intensity therapy); not candidate for high-intensity therapy
Dosage Modifications
Severe renal impairment (CrCl <30 mL/min): 5 mg qDay initially
Coadministration with dronedarone, verapamil, or diltiazem: Do not exceed 10 mg/day
Coadministration with amiodarone, amlodipine, or ranolazine: Do not exceed 20 mg/day
Coadministration with lomitapide: Reduce simvastatin dose by 50%, and do not exceed 20 mg/day (or 40 mg/day in those previously tolerating 80 mg/day) when initiating lomitapide
Dosing Considerations
Lipid determinations should be performed after 4 weeks of therapy and periodically thereafter
Limitation of use (oral suspension): Not studied in conditions where the major abnormality is elevation of chylomicrons (ie, hyperlipidemia Fredrickson types I and V)
Restricted dosing
- 80 mg/day should be used only for individuals who have been taking simvastatin 80 mg chronically (eg, ≥12 months) without evidence of myopathy or rhabdomyolysis
- Patients tolerating 80 mg who need to be initiated on an interacting drug that is contraindicated or associated with a maximum dose for simvastatin should be switched to an alternative statin with less potential for drug-drug interactions
- Patients unable to achieve their LDL-C goal utilizing 40 mg/day should not be titrated to 80 mg (increased risk for myopathy) but should instead be placed on alternative LDL-C-lowering treatment that provides greater LDL-C lowering
Overdose management
- Adverse drug reactions from overdose may include peripheral neuropathy, diarrhea, increased K+, myopathy, rhabdomyolysis, acute renal failure, elevated LFTs, and eye lens opacities
- Treatment is supportive

Simvastatin and myopathy risk
- Myopathy/rhabdomyolysis with acute renal failure and/or myopathy reported; monitor patient closely, including reports of recurrence when the same or a different statin was administered
- Dose adjustment required when coadministered with niacin, amiodarone, verapamil, diltiazem, amlodipine, and ranolazine
- Predisposing factors for myopathy include advanced age (>65 years), uncontrolled hypothyroidism, and renal impairment
- Withhold or discontinue if myopathy, renal failure, or transaminase levels >3x ULN develop
- Risk of myopathy is greater in patients taking simvastatin 80 daily dosage, especially in the 1st year of treatment compared with patients taking lower dosages and compared with patients using other statins with similar or greater LDL-C-lowering efficacy
- Use 80 mg daily dosage only in patients who have been taking simvastatin 80 mg daily chronically without evidence of muscle toxicity; if patients treated with an 80 mg daily dosage are prescribed an interacting drug that increases risk for myopathy and rhabdomyolysis, switch to an alternate statin
- Inform patients of risk of myopathy and rhabdomyolysis when starting or increasing therapy and advise patients receiving 80 mg daily dosage of increased risk of myopathy and rhabdomyolysis; instruct patients to promptly report any unexplained muscle pain, tenderness, or weakness, particularly if accompanied by malaise or fever
Immune-mediated necrotizing myopathy
- Immune-mediated necrotizing myopathy (IMNM), an autoimmune myopathy, reported with statin use
- IMNM is characterized by muscle biopsy showing necrotizing myopathy without significant inflammation improvement with immunosuppressive agents, proximal muscle weakness, and elevated serum creatine kinase, which persist despite discontinuation of statin treatment
- Treatment with immunosuppressive agents may be required
- Advice all patients starting therapy or whose dose is being increased, about the risk of myopathy, including rhabdomyolysis
- Patients should report promptly any unexplained muscle pain, tenderness, or weakness particularly if accompanied by malaise or fever or if muscle signs and symptoms persist after discontinuing therapy; additional neuromuscular and serologic testing may be necessary
- Therapy should be discontinued immediately if myopathy is diagnosed or suspected
- Discontinue therapy if markedly elevated creatine kinase (CK) levels occur or if myopathy diagnosed or suspected
- Therapy should be temporarily withheld in any patient experiencing an acute or serious condition predisposing to development of renal failure secondary to rhabdomyolysis, eg, sepsis; hypotension; dehydration; major surgery; trauma; severe metabolic, endocrine, and electrolyte disorders; or uncontrolled epilepsy
- 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
- 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
Coadministration with niacin
- Myopathy/rhabdomyolysis observed with simvastatin coadministered with lipid-modifying niacin doses (ie, ≥1 g/day); also observed when coadministered with daptomycin
- Risk of myopathy is greater in Chinese patients, and therefore, coadministration of simvastatin with lipid-modifying niacin doses is not recommended in Chinese patients
- Unknown if this risk applies to other patients of Asian descent
Drug interaction overview
- Simvastatin is a substrate of CYP3A4 and the transport protein OATP1B1; exposure can be significantly increased with concomitant administration of inhibitors of CYP3A4 and OATP1B1;
- Reduce dose by 50% if initiating lomitapide; do not exceed 20 mg daily (or simvastatin 40 mg daily for patients who have previously taken 80 mg daily dosage chronically) while taking lomitapide
Pregnancy & Lactation
Pregnancy
Discontinue therapy when pregnancy recognized; alternatively, consider ongoing therapeutic needs of individual patient
Therapy decreases synthesis of cholesterol and possibly other biologically active substances derived from cholesterol; therefore, this drug may cause fetal harm when administered to pregnant patients based on mechanism of action; in addition, treatment of hyperlipidemia is not generally necessary during pregnancy
Atherosclerosis is a chronic process and discontinuation of lipid-lowering drugs during pregnancy should have little impact on outcome of long-term therapy of primary hyperlipidemia for most patients
Available data from case series and prospective and retrospective observational cohort studies over decades of use with statins in pregnant women have not identified a drug-associated risk of major congenital malformations
Published data from prospective and retrospective observational cohort studies, use in pregnant women are insufficient to determine if there is a drug-associated risk of miscarriage
Contraception
- Advise females of reproductive potential to use effective contraception during treatment
Animal data
- In animal reproduction studies, no adverse developmental effects were observed in pregnant rats or rabbits orally administered simvastatin during period of organogenesis at doses that resulted in 2.5 and 2 times, respectively, the human exposure at maximum recommended human dosage of 80 mg/day, based on body surface area (mg/m2)
Lactation
There is no information about presence of this drug in human or animal milk, effects on breastfed infant or on milk production; however, it has been shown that another drug in this class passes into human milk; statins, including this drug, decrease cholesterol synthesis and possibly synthesis of other biologically active substances derived from cholesterol and may cause harm to breastfed infant
Because of potential for serious adverse reactions in breastfed infant, based on the mechanism of action, advise patients that breastfeeding is not recommended during treatment with this drug
For patients with lower risk, temporarily stop statin therapy until breastfeeding ends
Patients who are at high risk of heart attack or stroke who require statins after delivery should not breastfeed and should use alternatives such as infant formula
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
HMG-CoA reductase inhibitor; inhibits the rate-limiting step in cholesterol biosynthesis by competitively inhibiting HMG-CoA reductase
Absorption
Bioavailability: <5%
Onset of action: >3 days
Peak plasma time: 1.3-2.4 hr
Maximum effect: 4-6 weeks
Distribution
Protein bound: 95%
Metabolism
First pass in liver
Converted to maximally active simvastatin acid by nonenzymatic pathways and nonspecific enzymes
Metabolites: Beta-hydroxyacid and 6'-hydroxy, 6'-hydroxymethyl, and 6'-exomethylene derivatives (all active)
Simvastatin acid also converted to other active metabolites by CYP3A4
Elimination
Excretion: Feces (60%); urine (13%)
Pharmacogenomics
SLCO1B1 (OATP1B1) CC genotype significantly increases AUCs of parent drug and metabolites compared with the CT or TT genotypes
This polymorphism is proposed to reduce transport into the liver, the main site of statin metabolism and elimination, resulting in elevated plasma concentrations
SLCO1B1 polymorphism is thought to have a lesser effect on the more hydrophilic statins (eg, rosuvastatin, fluvastatin) compared with those that are more lipophilic (eg, atorvastatin, simvastatin)
Other genetic polymorphisms of elimination (eg, CYP450, P-glycoprotein) for each individual drug must also be considered, to explain variability for statin clearance among patients that exhibit SCLO1B1 polymorphism
SLCO1B1 CC genotype is most common in Caucasians and Asians (15%)
Risk of myopathy is 2.6- to 4.3-fold higher if the C allele is present and 16.9-fold higher in CC homozygotes than in TT homozygotes

SIMVASTATIN - ORAL
(SIM-va-STAT-in)

It belongs to a group of drugs known as "statins." It works by reducing the amount of cholesterol made by the liver. Lowering "bad" cholesterol and triglycerides and raising "good" cholesterol decreases the risk of heart disease and helps prevent strokes and heart attacks.In addition to eating a proper diet (such as a low-cholesterol/low-fat diet), other lifestyle changes that may help this medication work better include exercising, losing weight if overweight, and stopping smoking.
