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 recommended 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. In patients with CHD or multiple risk factors for
CHD, LIPITOR can be started simultaneously with diet.
1.1 Prevention of Cardiovascular Disease

findings are present:
LDL-C remains ≥ 190 mg/dL or
LDL-C remains ≥ 160 mg/dL and:
there is a positive family history of premature cardiovascular disease
or
two or more other CVD risk factors are present in the pediatric
patient
1.3 Limitations of Use
SPL UNCLASSIFIED SECTION
LIPITOR has not been studied in conditions where the major
lipoprotein abnormality is elevation of chylomicrons (Fredrickson Types I and V).
2 DOSAGE AND ADMINISTRATION
DOSAGE & ADMINISTRATION SECTION
2.1 Hyperlipidemia (Heterozygous Familial and Nonfamilial) and Mixed Dyslipidemia (Fredrickson Types IIa and IIb)
SPL UNCLASSIFIED SECTION
The recommended starting dose of LIPITOR is 10 or 20 mg once
daily. Patients who require a large reduction in LDL-C (more than 45%) may be
started at 40 mg once daily. The dosage range of LIPITOR is 10 to 80 mg once
daily. LIPITOR can be administered as a single dose at any time of the day, with
or without food. The starting dose and maintenance doses of LIPITOR should be
individualized according to patient characteristics such as goal of therapy and
response (see current NCEP Guidelines). After
initiation and/or upon titration of LIPITOR, lipid levels should be analyzed
within 2 to 4 weeks and dosage adjusted accordingly.
2.2 Heterozygous Familial Hypercholesterolemia in Pediatric Patients (10–17 years of age)
SPL UNCLASSIFIED SECTION
The recommended starting dose of LIPITOR is 10 mg/day; the
maximum recommended dose is 20 mg/day (doses greater than 20 mg have not been
studied in this patient population). Doses should be individualized according to
the recommended goal of therapy [see current NCEP Pediatric
Panel Guidelines, Clinical
Pharmacology (12), and
Indications and Usage (1.2)]. Adjustments should be made at intervals
of 4 weeks or more.
2.3 Homozygous Familial Hypercholesterolemia
SPL UNCLASSIFIED SECTION
The dosage of LIPITOR in patients with homozygous FH is 10 to 80
mg daily. LIPITOR should be used as an adjunct to other lipid-lowering
treatments (e.g., LDL apheresis) in these patients or if such treatments are
unavailable.
2.6 Dosage in Patients Taking Cyclosporine, Clarithromycin, Itraconazole, or a Combination of Ritonavir plus Saquinavir or Lopinavir plus Ritonavir
SPL UNCLASSIFIED SECTION
In patients taking cyclosporine, therapy should be limited to
LIPITOR 10 mg once daily. In patients taking clarithromycin, itraconazole, or in
patients with HIV taking a combination of ritonavir plus saquinavir or lopinavir
plus ritonavir, for doses of LIPITOR exceeding 20 mg, appropriate clinical
assessment is recommended to ensure that the lowest dose necessary of LIPITOR is
employed [see Warnings and Precautions,
Skeletal Muscle (5.1), Drug Interactions (7)].
Active liver disease, which may include unexplained persistent elevations in hepatic transaminase levels.
4.2 Hypersensitivity
SPL UNCLASSIFIED SECTION
Hypersensitivity to any component of this medication.
4.3 Pregnancy
SPL UNCLASSIFIED SECTION
Women who are pregnant or may become pregnant. LIPITOR may cause fetal harm when administered to a
pregnant woman. Serum cholesterol and triglycerides increase during normal
pregnancy, and cholesterol or cholesterol derivatives are essential for fetal
development. 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. There are no adequate and
well-controlled studies of LIPITOR use during pregnancy; however in rare
reports, congenital anomalies were observed following intrauterine exposure to
statins. In rat and rabbit animal reproduction studies, atorvastatin revealed no
evidence of teratogenicity. LIPITOR 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, LIPITOR should be discontinued immediately and the
patient apprised of the potential hazard to the fetus [see Use in Specific Populations (8.1)].
4.4 Nursing mothers
SPL UNCLASSIFIED SECTION
It is not known whether atorvastatin is excreted into human milk;
however a small amount of another drug in this class does pass into breast milk.
Because statins have the potential for serious adverse reactions in nursing
infants, women who require LIPITOR treatment should not breastfeed their infants
[see Use in Specific Populations
(8.3)].
5 WARNINGS AND PRECAUTIONS
WARNINGS AND PRECAUTIONS SECTION
5.1 Skeletal Muscle
SPL UNCLASSIFIED SECTION
Rare cases of rhabdomyolysis with acute renal
failure secondary to myoglobinuria have been reported with LIPITOR and with
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.
Atorvastatin, like other statins, occasionally causes myopathy, defined as
muscle aches or muscle weakness in conjunction with increases in creatine
phosphokinase (CPK) values >10 times ULN. The concomitant use of higher doses
of atorvastatin with certain drugs such as cyclosporine and strong CYP3A4
inhibitors (e.g., clarithromycin, itraconazole, and HIV protease inhibitors)
increases the risk of myopathy/rhabdomyolysis.
Myopathy should be considered in any patient with diffuse myalgias, muscle
tenderness or weakness, and/or marked elevation of CPK. Patients should be
advised to report promptly unexplained muscle pain, tenderness, or weakness,
particularly if accompanied by malaise or fever. LIPITOR therapy should be
discontinued if markedly elevated CPK levels occur or myopathy is diagnosed or
suspected.
The risk of myopathy during treatment with drugs in this class is increased
with concurrent administration of cyclosporine, fibric acid derivatives,
erythromycin, clarithromycin, combination of ritonavir plus saquinavir or
lopinavir plus ritonavir, niacin, or azole antifungals. Physicians considering
combined therapy with LIPITOR and fibric acid derivatives, erythromycin,
clarithromycin, a combination of ritonavir plus saquinavir or lopinavir plus
ritonavir, immunosuppressive drugs, azole antifungals, or lipid-modifying doses
of niacin should carefully weigh the potential benefits and risks and should
carefully monitor patients for any signs or symptoms of muscle pain, tenderness,
or weakness, particularly during the initial months of therapy and during any
periods of upward dosage titration of either drug. Lower starting and
maintenance doses of atorvastatin should be considered when taken concomitantly
with the aforementioned drugs (see Drug
Interactions (7)). Periodic creatine phosphokinase (CPK)
determinations may be considered in such situations, but there is no assurance
that such monitoring will prevent the occurrence of severe myopathy.
Table 1. Drug Interactions Associated with Increased Risk of
Myopathy/Rhabdomyolysis
Interacting Agents
Prescribing Recommendations
Cyclosporine
Do not exceed 10 mg atorvastatin daily
Clarithromycin, itraconazole, HIV protease inhibitors
(ritonavir plus saquinavir or lopinavir plus ritonavir)
Caution when exceeding doses > 20mg atorvastatin daily. The
lowest dose necessary should be used.
LIPITOR therapy should be temporarily withheld or
discontinued in any patient with an acute, serious condition suggestive of a
myopathy or having a risk factor predisposing to the development of renal
failure secondary to rhabdomyolysis (e.g., severe acute infection, hypotension,
major surgery, trauma, severe metabolic, endocrine and electrolyte disorders,
and uncontrolled seizures).
5.2 Liver Dysfunction
SPL UNCLASSIFIED SECTION
Statins, like some other lipid-lowering therapies, have been
associated with biochemical abnormalities of liver function. Persistent elevations (>3 times the upper limit of normal [ULN]
occurring on 2 or more occasions) in serum transaminases occurred in 0.7% of
patients who received LIPITOR in clinical trials. The incidence of these
abnormalities was 0.2%, 0.2%, 0.6%, and 2.3% for 10, 20, 40, and 80 mg,
respectively.
One patient in clinical trials developed jaundice. Increases in liver
function tests (LFT) in other patients were not associated with jaundice or
other clinical signs or symptoms. Upon dose reduction, drug interruption, or
discontinuation, transaminase levels returned to or near pretreatment levels
without sequelae. Eighteen of 30 patients with persistent LFT elevations
continued treatment with a reduced dose of LIPITOR.
It is recommended that liver function tests be performed prior to and at 12
weeks following both the initiation of therapy and any elevation of dose, and
periodically (e.g., semiannually) thereafter. Liver enzyme changes generally
occur in the first 3 months of treatment with LIPITOR. Patients who develop
increased transaminase levels should be monitored until the abnormalities
resolve. Should an increase in ALT or AST of >3 times ULN persist, reduction
of dose or withdrawal of LIPITOR is recommended.
LIPITOR should be used with caution in patients who consume substantial
quantities of alcohol and/or have a history of liver disease. Active liver
disease or unexplained persistent transaminase elevations are contraindications
to the use of LIPITOR [see Contraindications
(4.1)].
5.3 Endocrine Function
SPL UNCLASSIFIED SECTION
Statins interfere with cholesterol synthesis and theoretically might blunt
adrenal and/or gonadal steroid production. Clinical studies have shown that
LIPITOR does not reduce basal plasma cortisol concentration or impair adrenal
reserve. The effects of statins on male fertility have not been studied in
adequate numbers of patients. The effects, if any, on the pituitary-gonadal axis
in premenopausal women are unknown. Caution should be exercised if a statin is
administered concomitantly with drugs that may decrease the levels or activity
of endogenous steroid hormones, such as ketoconazole, spironolactone, and
cimetidine.
5.4 CNS Toxicity
SPL UNCLASSIFIED SECTION
Brain hemorrhage was seen in a female dog treated for 3 months at
120 mg/kg/day. Brain hemorrhage and optic nerve vacuolation were seen in another
female dog that was sacrificed in moribund condition after 11 weeks of
escalating doses up to 280 mg/kg/day. The 120 mg/kg dose resulted in a systemic
exposure approximately 16 times the human plasma area-under-the-curve (AUC, 0–24
hours) based on the maximum human dose of 80 mg/day. A single tonic convulsion
was seen in each of 2 male dogs (one treated at 10 mg/kg/day and one at 120
mg/kg/day) in a 2-year study. No CNS lesions have been observed in mice after
chronic treatment for up to 2 years at doses up to 400 mg/kg/day or in rats at
doses up to 100 mg/kg/day. These doses were 6 to 11 times (mouse) and 8 to 16
times (rat) the human AUC (0–24) based on the maximum recommended human dose of
80 mg/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 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
at a dose that produced plasma drug levels about 30 times higher than the mean
drug level in humans taking the highest recommended dose.
5.5 Use in Patients with Recent Stroke or TIA
SPL UNCLASSIFIED SECTION
In a post-hoc analysis of the Stroke Prevention by Aggressive
Reduction in Cholesterol Levels (SPARCL) study where LIPITOR 80 mg vs. placebo
was administered in 4,731 subjects without CHD who had a stroke or TIA within
the preceding 6 months, a higher incidence of hemorrhagic stroke was seen in the
LIPITOR 80 mg group compared to placebo (55, 2.3% atorvastatin vs. 33, 1.4%
placebo; HR: 1.68, 95% CI: 1.09, 2.59; p=0.0168). The incidence of fatal
hemorrhagic stroke was similar across treatment groups (17 vs. 18 for the
atorvastatin and placebo groups, respectively). The incidence of nonfatal
hemorrhagic stroke was significantly higher in the atorvastatin group (38, 1.6%)
as compared to the placebo group (16, 0.7%). Some baseline characteristics,
including hemorrhagic and lacunar stroke on study entry, were associated with a
higher incidence of hemorrhagic stroke in the atorvastatin group [see Adverse Reactions (6.1)].
6 ADVERSE REACTIONS
ADVERSE REACTIONS SECTION
The following serious adverse reactions are discussed in greater
detail in other sections of the label:
Because clinical trials are conducted under widely varying
conditions, the adverse reaction rates observed in the clinical studies of a
drug cannot be directly compared to rates in the clinical trials of another drug
and may not reflect the rates observed in clinical practice.
In the LIPITOR placebo-controlled clinical trial database of 16,066 patients
(8755 LIPITOR vs. 7311 placebo; age range 10–93 years, 39% women, 91%
Caucasians, 3% Blacks, 2% Asians, 4% other) with a median treatment duration of
53 weeks, 9.7% of patients on LIPITOR and 9.5% of the patients on placebo
discontinued due to adverse reactions regardless of causality. The five most
common adverse reactions in patients treated with LIPITOR that led to treatment
discontinuation and occurred at a rate greater than placebo were: myalgia
(0.7%), diarrhea (0.5%), nausea (0.4%), alanine aminotransferase increase
(0.4%), and hepatic enzyme increase (0.4%).
The most commonly reported adverse reactions (incidence ≥ 2% and greater than
placebo) regardless of causality, in patients treated with LIPITOR in placebo
controlled trials (n=8755) were: nasopharyngitis (8.3%), arthralgia (6.9%),
diarrhea (6.8%), pain in extremity (6.0%), and urinary tract infection (5.7%).
Table 2 summarizes the frequency of clinical adverse reactions, regardless of
causality, reported in ≥ 2% and at a rate greater than placebo in patients
treated with LIPITOR (n=8755), from seventeen placebo-controlled trials.
Table 2. Clinical adverse reactions occurring in ≥ 2% in patents treated with any dose of LIPITOR and at an incidence greater than placebo regardless of causality (% of patients).
*Adverse Reaction ≥ 2% in any dose greater than placebo Other adverse reactions reported in placebo-controlled studies include:
Body as a whole: malaise, pyrexia; Digestive system: abdominal discomfort, eructation,
flatulence, hepatitis, cholestasis; Musculoskeletal
system: musculoskeletal pain, muscle fatigue, neck pain, joint swelling;
Metabolic and nutritional system: transaminases
increase, liver function test abnormal, blood alkaline phosphatase increase,
creatine phosphokinase increase, hyperglycemia; Nervous
system: nightmare; Respiratory system:
epistaxis; Skin and appendages: urticaria;
Special senses: vision blurred, tinnitus; Urogenital system: white blood cells urine positive.
Anglo-Scandinavian Cardiac Outcomes Trial
(ASCOT)
In ASCOT [see Clinical Studies
(14.1)] involving 10,305 participants (age range 40–80 years, 19%
women; 94.6% Caucasians, 2.6% Africans, 1.5% South Asians, 1.3% mixed/other)
treated with LIPITOR 10 mg daily (n=5,168) or placebo (n=5,137), the safety and
tolerability profile of the group treated with LIPITOR was comparable to that of
the group treated with placebo during a median of 3.3 years of follow-up.
Collaborative Atorvastatin Diabetes Study
(CARDS)
In CARDS [see Clinical Studies
(14.1)] involving 2,838 subjects (age range 39–77 years, 32% women;
94.3% Caucasians, 2.4% South Asians, 2.3% Afro-Caribbean, 1.0% other) with type
2 diabetes treated with LIPITOR 10 mg daily (n=1,428) or placebo (n=1,410),
there was no difference in the overall frequency of adverse reactions or serious
adverse reactions between the treatment groups during a median follow-up of 3.9
years. No cases of rhabdomyolysis were reported.
Treating to New Targets Study (TNT)
In TNT [see Clinical Studies
(14.1)] involving 10,001 subjects (age range 29–78 years, 19% women;
94.1% Caucasians, 2.9% Blacks, 1.0% Asians, 2.0% other) with clinically evident
CHD treated with LIPITOR 10 mg daily (n=5006) or LIPITOR 80 mg daily (n=4995),
there were more serious adverse reactions and discontinuations due to adverse
reactions in the high-dose atorvastatin group (92, 1.8%; 497, 9.9%,
respectively) as compared to the low-dose group (69, 1.4%; 404, 8.1%,
respectively) during a median follow-up of 4.9 years. Persistent transaminase
elevations (≥3 × ULN twice within 4–10 days) occurred in 62 (1.3%) individuals
with atorvastatin 80 mg and in nine (0.2%) individuals with atorvastatin 10 mg.
Elevations of CK (≥ 10 × ULN) were low overall, but were higher in the high-dose
atorvastatin treatment group (13, 0.3%) compared to the low-dose atorvastatin
group (6, 0.1%).
Incremental Decrease in Endpoints through
Aggressive Lipid Lowering Study (IDEAL)
In IDEAL [see Clinical Studies
(14.1)] involving 8,888 subjects (age range 26–80 years, 19% women;
99.3% Caucasians, 0.4% Asians, 0.3% Blacks, 0.04% other) treated with LIPITOR 80
mg/day (n=4439) or simvastatin 20–40 mg daily (n=4449), there was no difference
in the overall frequency of adverse reactions or serious adverse reactions
between the treatment groups during a median follow-up of 4.8 years.
Stroke Prevention by Aggressive Reduction in
Cholesterol Levels (SPARCL)
In SPARCL involving 4731 subjects (age range 21–92 years, 40% women; 93.3%
Caucasians, 3.0% Blacks, 0.6% Asians, 3.1% other) without clinically evident CHD
but with a stroke or transient ischemic attack (TIA) within the previous 6
months treated with LIPITOR 80 mg (n=2365) or placebo (n=2366) for a median
follow-up of 4.9 years, there was a higher incidence of persistent hepatic
transaminase elevations (≥ 3 × ULN twice within 4–10 days) in the atorvastatin
group (0.9%) compared to placebo (0.1%). Elevations of CK (>10 × ULN) were
rare, but were higher in the atorvastatin group (0.1%) compared to placebo
(0.0%). Diabetes was reported as an adverse reaction in 144 subjects (6.1%) in
the atorvastatin group and 89 subjects (3.8%) in the placebo group [see Warnings and Precautions (5.5)].
In a post-hoc analysis, LIPITOR 80 mg reduced the incidence of ischemic
stroke (218/2365, 9.2% vs. 274/2366, 11.6%) and increased the incidence of
hemorrhagic stroke (55/2365, 2.3% vs. 33/2366, 1.4%) compared to placebo. The
incidence of fatal hemorrhagic stroke was similar between groups (17 LIPITOR vs.
18 placebo). The incidence of non-fatal hemorrhagic strokes was significantly
greater in the atorvastatin group (38 non-fatal hemorrhagic strokes) as compared
to the placebo group (16 non-fatal hemorrhagic strokes). Subjects who entered
the study with a hemorrhagic stroke appeared to be at increased risk for
hemorrhagic stroke [7 (16%) LIPITOR vs. 2 (4%) placebo].
There were no significant differences between the treatment groups for
all-cause mortality: 216 (9.1%) in the LIPITOR 80 mg/day group vs. 211 (8.9%) in
the placebo group. The proportions of subjects who experienced cardiovascular
death were numerically smaller in the LIPITOR 80 mg group (3.3%) than in the
placebo group (4.1%). The proportions of subjects who experienced
non-cardiovascular death were numerically larger in the LIPITOR 80 mg group
(5.0%) than in the placebo group (4.0%).
6.2 Postmarketing Experience
SPL UNCLASSIFIED SECTION
The following adverse reactions have been identified during
postapproval use of LIPITOR. Because these reactions are reported voluntarily
from a population of uncertain size, it is not always possible to reliably
estimate their frequency or establish a causal relationship to drug
exposure.
Adverse reactions associated with LIPITOR therapy reported since market
introduction, that are not listed above, regardless of causality assessment,
include the following: anaphylaxis, angioneurotic edema, bullous rashes
(including erythema multiforme, Stevens-Johnson syndrome, and toxic epidermal
necrolysis), rhabdomyolysis, fatigue, tendon rupture, hepatic failure,
dizziness, memory impairment, depression, and peripheral neuropathy.
6.3 Pediatric Patients (ages 10-17 years)
SPL UNCLASSIFIED SECTION
In a 26-week controlled study in boys and postmenarchal girls
(n=140, 31% female; 92% Caucasians, 1.6% Blacks, 1.6% Asians, 4.8% other), the
safety and tolerability profile of LIPITOR 10 to 20 mg daily was generally
similar to that of placebo [see Clinical
Studies (14.6) and Use in Special
Populations, Pediatric Use (8.4)].
7 DRUG INTERACTIONS
DRUG INTERACTIONS SECTION
The risk of myopathy during treatment with statins is increased
with concurrent administration of fibric acid derivatives, lipid-modifying doses
of niacin, cyclosporine, or strong CYP 3A4 inhibitors (e.g., clarithromycin, HIV
protease inhibitors, and itraconazole) [see Warnings and Precautions, Skeletal Muscle (5.1) and
Clinical Pharmacology
(12.3)].
7.1 Strong Inhibitors of CYP 3A4
SPL UNCLASSIFIED SECTION
LIPITOR is metabolized by cytochrome P450 3A4. Concomitant
administration of LIPITOR with strong inhibitors of CYP 3A4 can lead to
increases in plasma concentrations of atorvastatin. The extent of interaction
and potentiation of effects depend on the variability of effect on CYP
3A4.
Clarithromycin: Atorvastatin AUC was significantly
increased with concomitant administration of LIPITOR 80 mg with clarithromycin
(500 mg twice daily) compared to that of LIPITOR alone [see Clinical Pharmacology (12.3)].
Therefore, in patients taking clarithromycin, caution should be used when the
LIPITOR dose exceeds 20 mg [see Warnings and
Precautions, Skeletal Muscle (5.1) and Dosage and Administration (2.6)]. Combination of Protease Inhibitors: Atorvastatin AUC
was significantly increased with concomitant administration of LIPITOR 40 mg
with ritonavir plus saquinavir (400 mg twice daily) or LIPITOR 20 mg with
lopinavir plus ritonavir (400 mg + 100 mg twice daily) compared to that of
LIPITOR alone [see Clinical Pharmacology
(12.3)]. Therefore, in patients taking HIV protease inhibitors,
caution should be used when the LIPITOR dose exceeds 20 mg [see Warnings and Precautions, Skeletal Muscle
(5.1) and Dosage and
Administration (2.6)]. Itraconazole: Atorvastatin AUC was significantly
increased with concomitant administration of LIPITOR 40 mg and itraconazole 200
mg [see Clinical Pharmacology
(12.3)]. Therefore, in patients taking itraconazole, caution should
be used when the LIPITOR dose exceeds 20 mg [see Warnings and Precautions, Skeletal Muscle (5.1) and
Dosage and Administration
(2.6)].
7.2 Grapefruit Juice
SPL UNCLASSIFIED SECTION
Contains one or more components that inhibit CYP 3A4 and can
increase plasma concentrations of atorvastatin, especially with excessive
grapefruit juice consumption (>1.2 liters per day).
7.3 Cyclosporine
SPL UNCLASSIFIED SECTION
Atorvastatin and atorvastatin-metabolites are substrates of the
OATP1B1 transporter. Inhibitors of the OATP1B1 (e.g., cyclosporine) can increase
the bioavailability of atorvastatin. Atorvastatin AUC was significantly
increased with concomitant administration of LIPITOR 10 mg and cyclosporine 5.2
mg/kg/day compared to that of LIPITOR alone [see Clinical Pharmacology (12.3)]. In cases where
co-administration of LIPITOR with cyclosporine is necessary, the dose of LIPITOR
should not exceed 10 mg [see Warnings and
Precautions, Skeletal Muscle (5.1)].
7.4 Rifamprin or other Induceder of Cytochrome P450 3A4
SPL UNCLASSIFIED SECTION
Concomitant administration of LIPITOR with inducers of cytochrome
P450 3A4 (e.g., efavirenz, rifampin) can lead to variable reductions in plasma
concentrations of atorvastatin. Due to the dual interaction mechanism of
rifampin, simultaneous co-administration of LIPITOR with rifampin is
recommended, as delayed administration of LIPITOR after administration of
rifampin has been associated with a significant reduction in atorvastatin plasma
concentrations.
7.5 Digoxin
SPL UNCLASSIFIED SECTION
When multiple doses of LIPITOR and digoxin were coadministered,
steady state plasma digoxin concentrations increased by approximately 20%.
Patients taking digoxin should be monitored appropriately.
7.6 Oral Contraceptives
SPL UNCLASSIFIED SECTION
Co-administration of LIPITOR and an oral contraceptive increased
AUC values for norethindrone and ethinyl estradiol [see Clinical Pharmacology (12.3)]. These increases should
be considered when selecting an oral contraceptive for a woman taking
LIPITOR.
7.7 Warfarin
SPL UNCLASSIFIED SECTION
LIPITOR had no clinically significant effect on prothrombin time
when administered to patients receiving chronic warfarin treatment.
8 USE IN SPECIFIC POPULATIONS
USE IN SPECIFIC POPULATIONS SECTION
Enter section text here
8.1 Pregnancy
PREGNANCY SECTION
Pregnancy Category X
LIPITOR is contraindicated in women who are or may become pregnant. Serum
cholesterol and triglycerides increase during normal pregnancy. Lipid lowering
drugs offer no benefit during pregnancy because cholesterol and cholesterol
derivatives are needed for normal fetal development. 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 atorvastatin use during
pregnancy. There have been rare reports of congenital anomalies following
intrauterine exposure to statins. In a review 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. However, this study was
only able to exclude a three-to-four-fold increased risk of congenital anomalies
over background incidence. In 89% of these cases, drug treatment started before
pregnancy and stopped during the first trimester when pregnancy was
identified.
Atorvastatin crosses the rat placenta and reaches a level in fetal liver
equivalent to that of maternal plasma. Atorvastatin was not teratogenic in rats
at doses up to 300 mg/kg/day or in rabbits at doses up to 100 mg/kg/day. These
doses resulted in multiples of about 30 times (rat) or 20 times (rabbit) the
human exposure based on surface area (mg/m2) [see Contraindications, Pregnancy
(4.3)].
In a study in rats given 20, 100, or 225 mg/kg/day, from gestation day 7
through to lactation day 21 (weaning), there was decreased pup survival at
birth, neonate, weaning, and maturity in pups of mothers dosed with 225
mg/kg/day. Body weight was decreased on days 4 and 21 in pups of mothers dosed
at 100 mg/kg/day; pup body weight was decreased at birth and at days 4, 21, and
91 at 225 mg/kg/day. Pup development was delayed (rotorod performance at 100
mg/kg/day and acoustic startle at 225 mg/kg/day; pinnae detachment and
eye-opening at 225 mg/kg/day). These doses correspond to 6 times (100 mg/kg) and
22 times (225 mg/kg) the human AUC at 80 mg/day.
Statins may cause fetal harm when administered to a pregnant woman. LIPITOR
should be administered to women of childbearing potential only when such
patients are highly unlikely to conceive and have been informed of the potential
hazards. If the woman becomes pregnant while taking LIPITOR, it should be
discontinued immediately and the patient advised again as to the potential
hazards to the fetus and the lack of known clinical benefit with continued use
during pregnancy.
8.3 Nursing Mothers
NURSING MOTHERS SECTION
It is not known whether atorvastatin is excreted in human milk,
but a small amount of another drug in this class does pass into breast milk.
Nursing rat pups had plasma and liver drug levels of 50% and 40%, respectively,
of that in their mother's milk. Animal breast milk drug levels may not
accurately reflect human breast milk levels. Because another drug in this class
passes into human milk and because statins have a potential to cause serious
adverse reactions in nursing infants, women requiring LIPITOR treatment should
be advised not to nurse their infants [seeContraindications (4)].
8.4 Pediatric Use
PEDIATRIC USE SECTION
Safety and effectiveness in patients 10–17 years of age with
heterozygous familial hypercholesterolemia have been evaluated in a controlled
clinical trial of 6 months' duration in adolescent boys and postmenarchal girls.
Patients treated with LIPITOR had an adverse experience profile generally
similar to that of patients treated with placebo. The most common adverse
experiences observed in both groups, regardless of causality assessment, were
infections. Doses greater than 20 mg have not been studied in
this patient population. In this limited controlled study, there was no
significant effect on growth or sexual maturation in boys or on menstrual cycle
length in girls [see Clinical Studies
(14.6); Adverse Reactions, Pediatric Patients (ages 10–17
years) (6.3); and Dosage and
Administration, Heterozygous Familial Hypercholesterolemia in Pediatric Patients
(10–17 years of age) (2.2)]. Adolescent females should be counseled
on appropriate contraceptive methods while on LIPITOR therapy [see Contraindications, Pregnancy (4.3) and
Use in Specific Populations, Pregnancy
(8.1)]. LIPITOR has not been studied in controlled
clinical trials involving pre-pubertal patients or patients younger than 10
years of age.
Of the 39,828 patients who received LIPITOR in clinical studies,
15,813 (40%) were ≥65 years old and 2,800 (7%) were ≥75 years old. No overall
differences in safety or effectiveness were observed between these subjects and
younger subjects, and other reported clinical experience has not identified
differences in responses between the elderly and younger patients, but greater
sensitivity of some older adults cannot be ruled out. Since advanced age (≥65
years) is a predisposing factor for myopathy, LIPITOR should be prescribed with
caution in the elderly.
8.6 Hepatic Impairment
SPL UNCLASSIFIED SECTION
Lipitor is contraindicated in patients with active liver disease
which may include unexplained persistent elevations in hepatic transaminase
levels [see Contraindications (4)
and Pharmacokinetics
(12.3)].
10 OVERDOSAGE
OVERDOSAGE SECTION
There is no specific treatment for LIPITOR overdosage. In the event of an
overdose, the patient should be treated symptomatically, and supportive measures
instituted as required. Due to extensive drug binding to plasma proteins,
hemodialysis is not expected to significantly enhance LIPITOR clearance.
11 DESCRIPTION
DESCRIPTION SECTION
LIPITOR is a synthetic lipid-lowering agent. Atorvastatin is an
inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase. This
enzyme catalyzes the conversion of HMG-CoA to mevalonate, an early and
rate-limiting step in cholesterol biosynthesis.
Atorvastatin calcium is [R-(R*, R*)]-2-(4-fluorophenyl)-ß,
δ-dihydroxy-5-(1-methylethyl)-3-phenyl-4-[(phenylamino)carbonyl]-1H-pyrrole-1-heptanoic
acid, calcium salt (2:1) trihydrate. The empirical formula of atorvastatin
calcium is (C33H34 FN2O5)2Ca•3H2O and its molecular weight is 1209.42. Its structural formula
is:
image of chemical structure
Atorvastatin calcium is a white to off-white crystalline powder that is
insoluble in aqueous solutions of pH 4 and below. Atorvastatin calcium is very
slightly soluble in distilled water, pH 7.4 phosphate buffer, and acetonitrile;
slightly soluble in ethanol; and freely soluble in methanol.
LIPITOR Tablets for oral administration contain 10, 20, 40, or 80 mg
atorvastatin and the following inactive ingredients: calcium carbonate, USP;
candelilla wax, FCC; croscarmellose sodium, NF; hydroxypropyl cellulose, NF;
lactose monohydrate, NF; magnesium stearate, NF; microcrystalline cellulose, NF;
Opadry White YS-1-7040 (hypromellose, polyethylene glycol, talc, titanium
dioxide); polysorbate 80, NF; simethicone emulsion.

12.1 Mechanism of Action
MECHANISM OF ACTION SECTION
LIPITOR is a selective, competitive inhibitor of HMG-CoA
reductase, the rate-limiting enzyme that converts
3-hydroxy-3-methylglutaryl-coenzyme A to mevalonate, a precursor of sterols,
including cholesterol. Cholesterol and triglycerides circulate in the
bloodstream as part of lipoprotein complexes. With ultracentrifugation, these
complexes separate into HDL (high-density lipoprotein), IDL
(intermediate-density lipoprotein), LDL (low-density lipoprotein), and VLDL
(very-low-density lipoprotein) fractions. Triglycerides (TG) and cholesterol in
the liver are incorporated into VLDL and released into the plasma for delivery
to peripheral tissues. LDL is formed from VLDL and is catabolized primarily
through the high-affinity LDL receptor. Clinical and pathologic studies show
that elevated plasma levels of total cholesterol (total-C), LDL-cholesterol
(LDL-C), and apolipoprotein B (apo B) promote human atherosclerosis and are risk
factors for developing cardiovascular disease, while increased levels of HDL-C
are associated with a decreased cardiovascular risk.
In animal models, LIPITOR lowers plasma cholesterol and lipoprotein levels by
inhibiting HMG-CoA reductase and cholesterol synthesis in the liver and by
increasing the number of hepatic LDL receptors on the cell surface to enhance
uptake and catabolism of LDL; LIPITOR also reduces LDL production and the number
of LDL particles. LIPITOR reduces LDL-C in some patients with homozygous
familial hypercholesterolemia (FH), a population that rarely responds to other
lipid-lowering medication(s).
A variety of clinical studies have demonstrated that elevated levels of
total-C, LDL-C, and apo B (a membrane complex for LDL-C) promote human
atherosclerosis. Similarly, decreased levels of HDL-C (and its transport
complex, apo A) are associated with the development of atherosclerosis.
Epidemiologic investigations have established that cardiovascular morbidity and
mortality vary directly with the level of total-C and LDL-C, and inversely with
the level of HDL-C.
LIPITOR reduces total-C, LDL-C, and apo B in patients with homozygous and
heterozygous FH, nonfamilial forms of hypercholesterolemia, and mixed
dyslipidemia. LIPITOR also reduces VLDL-C and TG and produces variable increases
in HDL-C and apolipoprotein A-1. LIPITOR reduces total-C, LDL-C, VLDL-C, apo B,
TG, and non-HDL-C, and increases HDL-C in patients with isolated
hypertriglyceridemia. LIPITOR reduces intermediate density lipoprotein
cholesterol (IDL-C) in patients with dysbetalipoproteinemia.
Like LDL, cholesterol-enriched triglyceride-rich lipoproteins, including
VLDL, intermediate density lipoprotein (IDL), and remnants, can also promote
atherosclerosis. Elevated plasma triglycerides are frequently found in a triad
with low HDL-C levels and small LDL particles, as well as in association with
non-lipid metabolic risk factors for coronary heart disease. As such, total
plasma TG has not consistently been shown to be an independent risk factor for
CHD. Furthermore, the independent effect of raising HDL or lowering TG on the
risk of coronary and cardiovascular morbidity and mortality has not been
determined.
12.2 Pharmacodynamics
PHARMACODYNAMICS SECTION
LIPITOR, as well as some of its metabolites, are
pharmacologically active in humans. The liver is the primary site of action and
the principal site of cholesterol synthesis and LDL clearance. Drug dosage,
rather than systemic drug concentration, correlates better with LDL-C reduction.
Individualization of drug dosage should be based on therapeutic response
[see Dosage and Administration
(2)].
12.3 Pharmacokinetics
PHARMACOKINETICS SECTION
Absorption: LIPITOR is rapidly absorbed
after oral administration; maximum plasma concentrations occur within 1 to 2
hours. Extent of absorption increases in proportion to LIPITOR dose. The
absolute bioavailability of atorvastatin (parent drug) is approximately 14% and
the systemic availability of HMG-CoA reductase inhibitory activity is
approximately 30%. The low systemic availability is attributed to presystemic
clearance in gastrointestinal mucosa and/or hepatic first-pass metabolism.
Although food decreases the rate and extent of drug absorption by approximately
25% and 9%, respectively, as assessed by Cmax and AUC, LDL-C reduction is
similar whether LIPITOR is given with or without food. Plasma LIPITOR
concentrations are lower (approximately 30% for Cmax and AUC) following evening
drug administration compared with morning. However, LDL-C reduction is the same
regardless of the time of day of drug administration [see Dosage and Administration (2)].
Distribution: Mean volume of distribution
of LIPITOR is approximately 381 liters. LIPITOR is ≥98% bound to plasma
proteins. A blood/plasma ratio of approximately 0.25 indicates poor drug
penetration into red blood cells. Based on observations in rats, LIPITOR is
likely to be secreted in human milk [see Contraindications, Nursing Mothers (4.4) and Use in Specific Populations, Nursing Mothers
(8.3)].
Metabolism: LIPITOR is extensively
metabolized to ortho- and parahydroxylated derivatives and various
beta-oxidation products. In vitro inhibition of
HMG-CoA reductase by ortho- and parahydroxylated metabolites is equivalent to
that of LIPITOR. Approximately 70% of circulating inhibitory activity for
HMG-CoA reductase is attributed to active metabolites. In
vitro studies suggest the importance of LIPITOR metabolism by cytochrome
P450 3A4, consistent with increased plasma concentrations of LIPITOR in humans
following co-administration with erythromycin, a known inhibitor of this isozyme
[see Drug Interactions (7.1)]. In
animals, the ortho-hydroxy metabolite undergoes further glucuronidation.
Excretion: LIPITOR and its metabolites
are eliminated primarily in bile following hepatic and/or extra-hepatic
metabolism; however, the drug does not appear to undergo enterohepatic
recirculation. Mean plasma elimination half-life of LIPITOR in humans is
approximately 14 hours, but the half-life of inhibitory activity for HMG-CoA
reductase is 20 to 30 hours due to the contribution of active metabolites. Less
than 2% of a dose of LIPITOR is recovered in urine following oral
administration.
Specific Populations
Geriatric: Plasma concentrations of
LIPITOR are higher (approximately 40% for Cmax and 30% for AUC) in healthy
elderly subjects (age ≥65 years) than in young adults. Clinical data suggest a
greater degree of LDL-lowering at any dose of drug in the elderly patient
population compared to younger adults [see Use in Specific Populations, Geriatric Use (8.5)].
Pediatric: Pharmacokinetic data in the
pediatric population are not available.
Gender: Plasma concentrations of LIPITOR
in women differ from those in men (approximately 20% higher for Cmax and 10%
lower for AUC); however, there is no clinically significant difference in LDL-C
reduction with LIPITOR between men and women.
Hemodialysis: While studies have not been
conducted in patients with end-stage renal disease, hemodialysis is not expected
to significantly enhance clearance of LIPITOR since the drug is extensively
bound to plasma proteins.
Hepatic Impairment: In patients with
chronic alcoholic liver disease, plasma concentrations of LIPITOR are markedly
increased. Cmax and AUC are each 4-fold greater in patients with Childs-Pugh A
disease. Cmax and AUC are approximately 16-fold and 11-fold increased,
respectively, in patients with Childs-Pugh B disease [see Contraindications (4.1)].

Atorvastatin
*Data given as x-fold change represent a simple ratio between
co-administration and atorvastatin alone (i.e., 1-fold = no change). Data given
as % change represent % difference relative to atorvastatin alone (i.e., 0% = no

reported with excessive grapefruit consumption (≥ 750 mL – 1.2 liters per
day).§Single sample taken 8–16 h post dose.¶Due to the dual interaction mechanism of rifampin, simultaneous
co-administration of atorvastatin with rifampin is recommended, as delayed
administration of atorvastatin after administration of rifampin has been
associated with a significant reduction in atorvastatin plasma concentrations.

Co-administered Drugs
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION
In a 2-year carcinogenicity study in rats at dose levels of 10,
30, and 100 mg/kg/day, 2 rare tumors were found in muscle in high-dose females:
in one, there was a rhabdomyosarcoma and, in another, there was a fibrosarcoma.
This dose represents a plasma AUC (0–24) value of approximately 16 times the
mean human plasma drug exposure after an 80 mg oral dose.
A 2-year carcinogenicity study in mice given 100, 200, or 400 mg/kg/day
resulted in a significant increase in liver adenomas in high-dose males and
liver carcinomas in high-dose females. These findings occurred at plasma AUC
(0–24) values of approximately 6 times the mean human plasma drug exposure after
an 80 mg oral dose.
In vitro, atorvastatin was not mutagenic or
clastogenic in the following tests with and without metabolic activation: the
Ames test with Salmonella typhimurium and Escherichia coli, the HGPRT forward mutation assay in
Chinese hamster lung cells, and the chromosomal aberration assay in Chinese
hamster lung cells. Atorvastatin was negative in the in vivo
mouse micronucleus test.
Studies in rats performed at doses up to 175 mg/kg (15 times the human
exposure) produced no changes in fertility. There was aplasia and aspermia in
the epididymis of 2 of 10 rats treated with 100 mg/kg/day of atorvastatin for 3
months (16 times the human AUC at the 80 mg dose); testis weights were
significantly lower at 30 and 100 mg/kg and epididymal weight was lower at 100
mg/kg. Male rats given 100 mg/kg/day for 11 weeks prior to mating had decreased
sperm motility, spermatid head concentration, and increased abnormal sperm.
Atorvastatin caused no adverse effects on semen parameters, or reproductive
organ histopathology in dogs given doses of 10, 40, or 120 mg/kg for two
years.

14.1 Prevention of Cardiovascular Disease
SPL UNCLASSIFIED SECTION
In the Anglo-Scandinavian Cardiac Outcomes Trial (ASCOT), the
effect of LIPITOR on fatal and non-fatal coronary heart disease was assessed in
10,305 hypertensive patients 40–80 years of age (mean of 63 years), without a
previous myocardial infarction and with TC levels <251 mg/dL (6.5 mmol/L).
Additionally, all patients had at least 3 of the following cardiovascular risk
factors: male gender (81.1%), age >55 years (84.5%), smoking (33.2%),
diabetes (24.3%), history of CHD in a first-degree relative (26%), TC:HDL >6
(14.3%), peripheral vascular disease (5.1%), left ventricular hypertrophy
(14.4%), prior cerebrovascular event (9.8%), specific ECG abnormality (14.3%),
proteinuria/albuminuria (62.4%). In this double-blind, placebo-controlled study,
patients were treated with anti-hypertensive therapy (Goal BP <140/90 mm Hg
for non-diabetic patients; <130/80 mm Hg for diabetic patients) and allocated
to either LIPITOR 10 mg daily (n=5168) or placebo (n=5137), using a covariate
adaptive method which took into account the distribution of nine baseline
characteristics of patients already enrolled and minimized the imbalance of
those characteristics across the groups. Patients were followed for a median
duration of 3.3 years.
The effect of 10 mg/day of LIPITOR on lipid levels was similar to that seen
in previous clinical trials.
LIPITOR significantly reduced the rate of coronary events [either fatal
coronary heart disease (46 events in the placebo group vs. 40 events in the
LIPITOR group) or non-fatal MI (108 events in the placebo group vs. 60 events in
the LIPITOR group)] with a relative risk reduction of 36% [(based on incidences
of 1.9% for LIPITOR vs. 3.0% for placebo), p=0.0005 (see Figure 1)]. The risk reduction was consistent regardless of
age, smoking status, obesity, or presence of renal dysfunction. The effect of
LIPITOR was seen regardless of baseline LDL levels. Due to the small number of
events, results for women were inconclusive.
Figure 1: Effect of LIPITOR 10 mg/day on Cumulative
Incidence of Non-Fatal Myocardial Infarction or Coronary Heart Disease Death (in
ASCOT-LLA)
image of figure 1
LIPITOR also significantly decreased the relative risk for revascularization
procedures by 42%. Although the reduction of fatal and non-fatal strokes did not
reach a pre-defined significance level (p=0.01), a favorable trend was observed
with a 26% relative risk reduction (incidences of 1.7% for LIPITOR and 2.3% for
placebo). There was no significant difference between the treatment groups for
death due to cardiovascular causes (p=0.51) or noncardiovascular causes
(p=0.17).
In the Collaborative Atorvastatin Diabetes Study (CARDS), the effect of
LIPITOR on cardiovascular disease (CVD) endpoints was assessed in 2838 subjects
(94% white, 68% male), ages 40–75 with type 2 diabetes based on WHO criteria,
without prior history of cardiovascular disease and with LDL < 160 mg/dL and TG < 600 mg/dL. In addition to diabetes, subjects had 1 or more of the following
risk factors: current smoking (23%), hypertension (80%), retinopathy (30%), or
microalbuminuria (9%) or macroalbuminuria (3%). No subjects on hemodialysis were
enrolled in the study. In this multicenter, placebo-controlled, double-blind
clinical trial, subjects were randomly allocated to either LIPITOR 10 mg daily
(1429) or placebo (1411) in a 1:1 ratio and were followed for a median duration
of 3.9 years. The primary endpoint was the occurrence of any of the major
cardiovascular events: myocardial infarction, acute CHD death, unstable angina,
coronary revascularization, or stroke. The primary analysis was the time to
first occurrence of the primary endpoint.
Baseline characteristics of subjects were: mean age of 62 years, mean
HbA1c 7.7%; median LDL-C 120 mg/dL; median TC 207 mg/dL;
median TG 151 mg/dL; median HDL-C 52 mg/dL.
The effect of LIPITOR 10 mg/day on lipid levels was similar to that seen in
previous clinical trials.
LIPITOR significantly reduced the rate of major cardiovascular events
(primary endpoint events) (83 events in the LIPITOR group vs. 127 events in the
placebo group) with a relative risk reduction of 37%, HR 0.63, 95% CI (0.48,
0.83) (p=0.001) (see Figure 2). An effect of LIPITOR was
seen regardless of age, sex, or baseline lipid levels.
LIPITOR significantly reduced the risk of stroke by 48% (21 events in the
LIPITOR group vs. 39 events in the placebo group), HR 0.52, 95% CI (0.31, 0.89)
(p=0.016) and reduced the risk of MI by 42% (38 events in the LIPITOR group vs.
64 events in the placebo group), HR 0.58, 95.1% CI (0.39, 0.86) (p=0.007). There
was no significant difference between the treatment groups for angina,
revascularization procedures, and acute CHD death.
There were 61 deaths in the LIPITOR group vs. 82 deaths in the placebo group
(HR 0.73, p=0.059).

of Major Cardiovascular Event (myocardial infarction, acute CHD death, unstable
angina, coronary revascularization, or stroke) in CARDS
image of figure 2
In the Treating to New Targets Study (TNT), the effect of LIPITOR 80 mg/day
vs. LIPITOR 10 mg/day on the reduction in cardiovascular events was assessed in
10,001 subjects (94% white, 81% male, 38% >65 years) with clinically evident
coronary heart disease who had achieved a target LDL-C level <130 mg/dL after
completing an 8-week, open-label, run-in period with LIPITOR 10 mg/day. Subjects
were randomly assigned to either 10 mg/day or 80 mg/day of LIPITOR and followed
for a median duration of 4.9 years. The primary endpoint was the time-to-first
occurrence of any of the following major cardiovascular events (MCVE): death due
to CHD, non-fatal myocardial infarction, resuscitated cardiac arrest, and fatal
and non-fatal stroke. The mean LDL-C, TC, TG, non-HDL, and HDL cholesterol
levels at 12 weeks were 73, 145, 128, 98, and 47 mg/dL during treatment with 80
mg of LIPITOR and 99, 177, 152, 129, and 48 mg/dL during treatment with 10 mg of
LIPITOR.
Treatment with LIPITOR 80 mg/day significantly reduced the rate of MCVE (434
events in the 80 mg/day group vs. 548 events in the 10 mg/day group) with a
relative risk reduction of 22%, HR 0.78, 95% CI (0.69, 0.89), p=0.0002 (see Figure 3 and Table 5). The overall
risk reduction was consistent regardless of age (<65, >65) or gender.

*Atorvastatin 80 mg: atorvastatin 10 mg†Secondary endpoints not included in primary endpoint‡Component of other secondary endpoints
Of the events that comprised the primary efficacy endpoint, treatment with
LIPITOR 80 mg/day significantly reduced the rate of non-fatal, non-procedure
related MI and fatal and non-fatal stroke, but not CHD death or resuscitated
cardiac arrest (Table 5). Of the predefined secondary endpoints, treatment with
LIPITOR 80 mg/day significantly reduced the rate of coronary revascularization,
angina, and hospitalization for heart failure, but not peripheral vascular
disease. The reduction in the rate of CHF with hospitalization was only observed
in the 8% of patients with a prior history of CHF.
There was no significant difference between the treatment groups for
all-cause mortality (Table 5). The proportions of subjects who experienced
cardiovascular death, including the components of CHD death and fatal stroke,
were numerically smaller in the LIPITOR 80 mg group than in the LIPITOR 10 mg
treatment group. The proportions of subjects who experienced noncardiovascular
death were numerically larger in the LIPITOR 80 mg group than in the LIPITOR 10
mg treatment group.
In the Incremental Decrease in Endpoints Through Aggressive Lipid Lowering
Study (IDEAL), treatment with LIPITOR 80 mg/day was compared to treatment with
simvastatin 20–40 mg/day in 8,888 subjects up to 80 years of age with a history
of CHD to assess whether reduction in CV risk could be achieved. Patients were
mainly male (81%), white (99%) with an average age of 61.7 years, and an average
LDL-C of 121.5 mg/dL at randomization; 76% were on statin therapy. In this
prospective, randomized, open-label, blinded endpoint (PROBE) trial with no
run-in period, subjects were followed for a median duration of 4.8 years. The
mean LDL-C, TC, TG, HDL, and non-HDL cholesterol levels at Week 12 were 78, 145,
115, 45, and 100 mg/dL during treatment with 80 mg of LIPITOR and 105, 179, 142,
47, and 132 mg/dL during treatment with 20–40 mg of simvastatin.
There was no significant difference between the treatment groups for the
primary endpoint, the rate of first major coronary event (fatal CHD, non-fatal
MI, and resuscitated cardiac arrest): 411 (9.3%) in the LIPITOR 80 mg/day group
vs. 463 (10.4%) in the simvastatin 20–40 mg/day group, HR 0.89, 95% CI ( 0.78,
1.01), p=0.07.
There were no significant differences between the treatment groups for
all-cause mortality: 366 (8.2%) in the LIPITOR 80 mg/day group vs. 374 (8.4%) in
the simvastatin 20–40 mg/day group. The proportions of subjects who experienced
CV or non-CV death were similar for the LIPITOR 80 mg group and the simvastatin
20–40 mg group.
14.2 Hyperlipidemia (Heterozygous Familial and Nonfamilial) and Mixed Dyslipidemia (Fredrickson Types IIa and IIb)
SPL UNCLASSIFIED SECTION
LIPITOR reduces total-C, LDL-C, VLDL-C, apo B, and TG, and
increases HDL-C in patients with hyperlipidemia and mixed dyslipidemia.
Therapeutic response is seen within 2 weeks, and maximum response is usually
achieved within 4 weeks and maintained during chronic therapy.
LIPITOR is effective in a wide variety of patient populations with
hyperlipidemia, with and without hypertriglyceridemia, in men and women, and in
the elderly.
In two multicenter, placebo-controlled, dose-response studies in patients
with hyperlipidemia, LIPITOR given as a single dose over 6 weeks, significantly
reduced total-C, LDL-C, apo B, and TG. (Pooled results are provided in Table 6.)
TABLE 6. Dose Response in Patients With Primary Hyperlipidemia
(Adjusted Mean % Change From Baseline)*
In patients with Fredrickson Types IIa and IIb
hyperlipoproteinemia pooled from 24 controlled trials, the median (25th and 75th percentile) percent changes
from baseline in HDL-C for LIPITOR 10, 20, 40, and 80 mg were 6.4 (-1.4, 14),
8.7 (0, 17), 7.8 (0, 16), and 5.1 (-2.7, 15), respectively. Additionally,
analysis of the pooled data demonstrated consistent and significant decreases in
total-C, LDL-C, TG, total-C/HDL-C, and LDL-C/HDL-C.
In three multicenter, double-blind studies in patients with hyperlipidemia,
LIPITOR was compared to other statins. After randomization, patients were
treated for 16 weeks with either LIPITOR 10 mg per day or a fixed dose of the
comparative agent (Table 7).

The impact on clinical outcomes of the differences in lipid-altering effects
between treatments shown in Table 7 is not known. Table 7 does not contain data
comparing the effects of LIPITOR 10 mg and higher doses of lovastatin,
pravastatin, and simvastatin. The drugs compared in the studies summarized in
the table are not necessarily interchangeable.
14.3 Hypertriglyceridemia (Fredrickson Type IV)
SPL UNCLASSIFIED SECTION
The response to LIPITOR in 64 patients with isolated
hypertriglyceridemia treated across several clinical trials is shown in the
table below ( Table 8). For the LIPITOR-treated patients,

14.5 Homozygous Familial Hypercholoesterolemia
SPL UNCLASSIFIED SECTION
In a study without a concurrent control group, 29 patients ages 6
to 37 years with homozygous FH received maximum daily doses of 20 to 80 mg of
LIPITOR. The mean LDL-C reduction in this study was 18%. Twenty-five patients
with a reduction in LDL-C had a mean response of 20% (range of 7% to 53%, median
of 24%); the remaining 4 patients had 7% to 24% increases in LDL-C. Five of the
29 patients had absent LDL-receptor function. Of these, 2 patients also had a
portacaval shunt and had no significant reduction in LDL-C. The remaining 3
receptor-negative patients had a mean LDL-C reduction of 22%.
14.6 Heterozygous Familial Hypercholesterolemia in Pediatric Patients
SPL UNCLASSIFIED SECTION
In a double-blind, placebo-controlled study followed by an
open-label phase, 187 boys and postmenarchal girls 10–17 years of age (mean age
14.1 years) with heterozygous familial hypercholesterolemia (FH) or severe
hypercholesterolemia, were randomized to LIPITOR (n=140) or placebo (n=47) for
26 weeks and then all received LIPITOR for 26 weeks. Inclusion in the study
required 1) a baseline LDL-C level ≥ 190 mg/dL or 2) a baseline LDL-C level ≥
160 mg/dL and positive family history of FH or documented premature
cardiovascular disease in a first or second-degree relative. The mean baseline
LDL-C value was 218.6 mg/dL (range: 138.5–385.0 mg/dL) in the LIPITOR group
compared to 230.0 mg/dL (range: 160.0–324.5 mg/dL) in the placebo group. The
dosage of LIPITOR (once daily) was 10 mg for the first 4 weeks and uptitrated to
20 mg if the LDL-C level was > 130 mg/dL. The number of LIPITOR-treated
patients who required uptitration to 20 mg after Week 4 during the double-blind
phase was 80 (57.1%).
LIPITOR significantly decreased plasma levels of total-C, LDL-C,
triglycerides, and apolipoprotein B during the 26-week double-blind phase (see
Table 10).

the LIPITOR group compared to 228.5 mg/dL (range: 152.0–385.0 mg/dL) in the
placebo group during the 26-week double-blind phase.
The safety and efficacy of doses above 20 mg have not been studied in
controlled trials in children. The long-term efficacy of LIPITOR therapy in
childhood to reduce morbidity and mortality in adulthood has not been
established.

PATIENT INFORMATION
LIPITOR® atorvastatin calcium tablets
(LIP-ih-tore)
Read the Patient Information that comes with LIPITOR before you start taking
it and each time you get a refill. There may be new information. This leaflet
does not take the place of talking with your doctor about your condition or
treatment.
If you have any questions about LIPITOR, ask your doctor or pharmacist.
What is LIPITOR?
LIPITOR is a prescription medicine that lowers cholesterol in your blood. It
lowers the LDL-C ("bad" cholesterol) and triglycerides in your blood. It can
raise your HDL-C ("good" cholesterol) as well. LIPITOR is for adults and
children over 10 whose cholesterol does not come down enough with exercise and a
low-fat diet alone.
LIPITOR can lower the risk for heart attack, stroke, certain types of heart
surgery, and chest pain in patients who have heart disease or risk factors for
heart disease such as:
age, smoking, high blood pressure, low HDL-C, heart disease in the
family.
LIPITOR can lower the risk for heart attack or stroke in patients with
diabetes and risk factors such as:
eye problems, kidney problems, smoking, or high blood pressure.
LIPITOR starts to work in about 2 weeks.
What is Cholesterol?
Cholesterol and triglycerides are fats that are made in your body. They are
also found in foods. You need some cholesterol for good health, but too much is
not good for you. Cholesterol and triglycerides can clog your blood vessels. It
is especially important to lower your cholesterol if you have heart disease,
smoke, have diabetes or high blood pressure, are older, or if heart disease
starts early in your family.
