Crestor Safe and Effective When Used According to Prescribing Information

Conclusions from a review published in Circulation today regarding CRESTOR are misleading, and unfortunately create
unnecessary alarm for patients who need this medication to lower their cholesterol.


Conclusions from the Circulation review, based on adverse event reporting system (AERS) data gathered through September 2004,
stand in direct contrast to an FDA document issued on March 14, 2005, in response to a citizen's petition.


A copy of the FDA's document can be found at: fda/cder/drug/infopage/rosuvastatin/crestor_CP.pdf


The FDA has access to the most complete data set and according to their conclusion, "[o]ur review of all of the available
evidence (including preclinical data, pre-marketing clinical studies, Phase 4 clinical studies, and post-marketing adverse
event reports) indicates that CRESTOR does not pose a risk of muscle toxicity greater than the other approved statins, and
that with respect to renal toxicity, there is no convincing evidence that CRESTOR poses a risk of serious renal injury."



The Circulation report attempts to draw conclusions that simply can not be drawn from adverse event reporting data. The
FDA's own disclaimer on the front page of the AERS states, "the information contained in these [adverse event] reports has
not been scientifically or otherwise verified as to a cause and effect relationship and cannot be used to estimate the
incidence of adverse drug reactions."


It is important to note that the results of this study represent the conclusions of the authors only and do not represent the
official position of the AHA.


CRESTOR has been prescribed almost 22 million times for more than 4.7 million patients. AstraZeneca stands fully behind the
safety and effectiveness of CRESTOR when the product is used according to the prescribing information.


About CRESTOR


CRESTOR (rosuvastatin
calcium) is a once-daily prescription medication for use as an adjunct to diet in the treatment of various lipid
disorders including primary hypercholesterolemia, mixed dyslipidemia and isolated hypertriglyceridemia. It is a member of
the statin (HMG-CoA reductase inhibitors) class of drug therapy. CRESTOR has not been determined to prevent heart disease,
heart attacks, or strokes. For patients with hypercholesterolemia and mixed dyslipidemia, the usual recommended starting dose
of CRESTOR is 10 mg. Initiation of therapy with 5 mg once daily should be considered for patients requiring less aggressive
LDL-C reductions or who have predisposing factors for myopathy. For patients with marked hypercholesterolemia (LDL-C >190
mg/dL) and aggressive lipid targets, a 20-mg starting dose may be considered. AstraZeneca licensed worldwide rights to
CRESTOR from the Japanese pharmaceutical company Shionogi & Co., Ltd.















Important Safety Information


CRESTOR is contraindicated in patients with active liver disease or unexplained persistent elevations of serum transaminases,
in women who are pregnant or may become pregnant, and in nursing mothers. It is recommended that liver function tests be
performed before and at 12 weeks following both the initiation of therapy and any elevation of dose, and periodically (e.g.,
semiannually) thereafter. Rare cases of rhabdomyolysis with acute renal failure secondary to myoglobinuria have been reported
with CRESTOR and with other drugs in this class. The 40-mg dose of CRESTOR is reserved for those patients who have not
achieved LDL-C goal at 20 mg. CRESTOR should be prescribed with caution in patients with predisposing factors for myopathy,
such as renal impairment. Patients should be advised to promptly report unexplained muscle pain, tenderness, or weakness,
particularly if accompanied by malaise or fever.


CRESTOR is generally well-tolerated. Adverse reactions have usually been mild and transient. The most frequent adverse
events thought to be related to CRESTOR were myalgia (3.3%), constipation (1.4%), asthenia (1.3%), abdominal pain (1.3%) and
nausea (1.3%).
