LIPITOR safety information
IMPORTANT SAFETY INFORMATION
LIPITOR® (atorvastatin calcium) tablets are contraindicated in patients with a known hypersensitivity to any component of this product; in patients with active liver disease or unexplained persistent elevations of hepatic transaminases; in women who are or may become pregnant or who are breastfeeding. Advise females of reproductive potential of the risk to a fetus, to use effective contraception during treatment, and to inform their healthcare provider of a known or suspected pregnancy.
Rare cases of rhabdomyolysis with acute renal failure secondary to myoglobinuria have been reported with LIPITOR® (atorvastatin calcium) tablets and other statins. Tell patients to promptly report muscle pain, tenderness, or weakness. Predisposing factors include advanced age (≥65), uncontrolled hypothyroidism, and renal impairment. Patients with a history of renal impairment merit closer monitoring. In cases of myopathy or rhabdomyolysis, therapy should be temporarily withheld or discontinued.
The concomitant use of higher doses of LIPITOR® (atorvastatin calcium) tablets with certain drugs such as cyclosporine and strong CYP3A4 inhibitors (eg, clarithromycin, itraconazole, and HIV protease inhibitors) increases the risk of myopathy/rhabdomyolysis. Lower doses of LIPITOR should be considered. Physicians should carefully monitor patients for signs or symptoms of myopathy early during therapy and when titrating the dose of either drug.
It is recommended that liver function tests be performed prior to the initiation of therapy and repeated as clinically indicated thereafter.
Increases in HbA1c and fasting serum glucose levels have been reported with HMG-CoA reductase inhibitors, including LIPITOR® (atorvastatin calcium) tablets.
In a post hoc analysis of the SPARCL study in patients 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 (atorvastatin calcium) tablets group compared with placebo (2.3% vs 1.4%). Some baseline characteristics, including hemorrhagic and lacunar stroke on study entry, were associated with a higher incidence of hemorrhagic stroke in the LIPITOR group.
The most commonly reported adverse reactions with LIPITOR® (atorvastatin calcium) tablets in
Clinically Proven LDL-C Reductions
LIPITOR® (atorvastatin calcium) tablets provide LDL-C reductions of 39% to 60% across the full dose range1
LIPITOR® (atorvastatin calcium) tablets are contraindicated in patients with a known hypersensitivity to any component of this product; in patients with active liver disease or unexplained persistent elevations of hepatic transaminases; in women who are or may become pregnant or who are nursing.
Do your simvastatin patients need more help reaching their LDL-C goals?
The FDA recommends that patients who do not meet their LDL-C goal on simvastatin 40 mg be placed on alternative LDL-C-lowering treatments.3
CURVES (N=534) was an 8-week, randomized, open-label, parallel-group study that compared milligram-equivalent doses of LIPITOR® (atorvastatin calcium) tablets with simvastatin, pravastatin, lovastatin, and fluvastatin in patients with LDL-C ≥160 mg/dL and TG ≤400 mg/dL. Baseline LDL-C values were similar and patient demographics evenly distributed across treatment groups. Patients were randomized to LIPITOR 10 mg (n=73), 20 mg (n=51), 40 mg (n=61), or 80 mg (n=10); simvastatin 10 mg (n=70), 20 mg (n=49), or 40 mg (n=61); pravastatin 10 mg (n=14), 20 mg (n=41), or 40 mg (n=25); or lovastatin 20 mg (n=16), 40 mg (n=16), or 80 mg (n=11). LIPITOR 10 mg, 20 mg, and 40 mg produced greater reductions in LDL-C (38%, 46%, and 51%, respectively; P≤.01) compared with equivalent doses of simvastatin, pravastatin, lovastatin, and fluvastatin. LIPITOR 10 mg produced LDL-C reductions comparable with or greater than simvastatin 10 mg, 20 mg, and 40 mg (28%, 35%, and 41%, respectively); pravastatin 10 mg, 20 mg, and 40 mg (19%, 24%, and 34%, respectively); lovastatin 20 mg and 40 mg (29% and 31%, respectively); and fluvastatin 20 mg and 40 mg (17% and 23%, respectively).2
