Crestor
COMPOSITION
Each tablet contains 5 mg, 10mg or 20mg of rosuvastatin as
rosuvastatin calcium.
PHARMACEUTICAL FORM
Film-coated tablet.
Round, yellow coloured (5mg); Round, pink coloured (10mg and
20mg).
THERAPEUTIC INDICATIONS
CRESTOR (rosuvastatin calcium) is indicated as an adjunct to diet,
at least equivalent to the Adult Treatment Panel III (ATP III TLC diet),
for the reduction of elevated total cholesterol, LDL-cholesterol, ApoB,
the total cholesterol: HDL-cholesterol ratio and triglycerides and for
increasing HDL-C, in hyperlipidemic and dyslipidemic conditions, when
response to diet and exercise alone has been inadequate including :
Primary hypercholesterolaemia (Type IIa including heterozygous
familial hypercholesterolaemia and severe non-familial
hypercholesterolaemia)
Combined (mixed) dyslipidemia (Type IIb)
Homozygous familial hypercholesterolaemia where CRESTOR is used
either alone or as an adjunct to diet and other lipid lowering treatment
such as apheresis.
CRESTOR is indicated as adjunctive therapy to diet to slow the
progression of atherosclerosis in adult patients as part of a treatment
strategy to lower Total-C and LDL-C to target levels.
POSOLOGY AND METHOD OF ADMINISTRATION
Patients should be placed on a standard cholesterol-lowering diet (at
least equivalent to the Adult Treatment Panel III (ATP III TLC diet)) before
receiving CRESTOR (rosuvastatin calcium), and should continue on
this diet during treatment with CRESTOR. If appropriate, a program of
weight control and physical exercise should be implemented.
Prior to initiating therapy with CRESTOR, secondary causes for
elevations in plasma lipid levels should be excluded. A lipid profile
should also be performed.
The usual recommended starting dose of CRESTOR is 10 mg once
daily. However, initiation of therapy with 5 mg once daily should be
considered for patients requiring less aggressive LDL-C reductions.
The choice of starting dose should take into account the individual
patients' cholesterol level and future cardiovascular risk as well as the
potential risk for adverse reactions. CRESTOR may be taken in the
morning or evening, with or without food. The majority of patients are
controlled at the 10mg dose. However, if necessary, dose adjustments
to the next dose level can be made after 4-week intervals. The maximum
response is usually achieved within 2-4 weeks and is maintained during
chronic therapy. Increasing the dose to 40 mg should be reserved for
patients with severe hypercholesterolaemia at high cardiovascular risk
(in particular those with familial hypercholesterolaemia), who do not
achieve their treatment goal on 20 mg and should only be initiated
under specialist supervision (see Special Warnings and Precautions
for Use). The physician who elects to use CRESTOR at a dose higher
than 20 mg should periodically re-evaluate the long term risk/benefit of
CRESTOR for the individual patient. CRESTOR should be prescribed
with caution in patients with pre-disposing factors for myopathy /
rhabdomyolysis (see Special Warnings and Precautions for Use).
The dosage of CRESTOR should be individualised according to
baseline LDL-C, total-C/HDL-C ratio and/or TG levels, the recommended
target lipid values (see Recommendations for the Management and
Treatment of Dyslipidemia [Canada] summarised below in Table 1)
and/or the Third Report of the U.S. National Cholesterol Education
Program [NCEP Adult Treatment Panel III]) and the patient response.
The majority (80%) of patients treated with rosuvastatin 10 mg achieved
their NCEP ATP III treatment target for LDL-C levels; fewer subjects
(68%) achieved target on the 5 mg dose. The difference between
rosuvastatin 5 mg and 10 mg was greatest for high risk subjects (40
versus 61%, respectively), i.e. for subjects who have a lower LDL-C
target.
Lipid levels should be monitored periodically and, if necessary, the
dose of CRESTOR adjusted based on target lipid levels recommended
by guidelines.

The following reductions in total cholesterol, LDL-C, TG, Total-C/HDL
and increases in HDL-C have been observed in a dose-response
study, and may serve as a guide to treatment of patients with mild to
moderate hypercholesterolaemia:

Dosage in patients with renal insufficiency
The usual dose range applies in patients with mild to moderate renal
impairment.
The use of CRESTOR in patients with severe renal impairment is
contraindicated.
Dosage in patients with hepatic insufficiency
There was no increase in systemic exposure to rosuvastatin in subjects
with Child-Pugh scores of 7 or below. However, increased systemic
exposure has been observed in subjects with Child-Pugh scores of
8 and 9. In these patients an assessment of renal function should be
considered. There is no experience in subjects with Child-Pugh scores
above 9. CRESTOR is contraindicated in patients with active liver
disease.
Use in the elderly
Of the 10,275 patients in clinical studies with rosuvastatin, 3,159 (31%)
were 65 years and older, and 698 (6.8%) were 75 years and older.
The overall frequency of adverse events and types of adverse events
were similar in patients above and below 65 years of age. The efficacy
of rosuvastatin in the geriatric population (≥
65 years of age) was
comparable to the efficacy observed in the non-elderly.
Use in children
The safety and effectiveness in children have not been established.
Treatment experience with rosuvastatin in a children population is
limited to 8 patients with homozygous FH. None of these patients was
below 8 years of age.
Dosage on Asian Patients
Initiation of CRESTOR therapy with 5 mg once daily should be
considered for Asian patients. The potential for increased systemic
exposures relative to Caucasians is relevant when considering
escalation of dose in cases where hypercholesterolaemia is not
adequately controlled at doses of 5, 10 or 20 mg once daily (see
Special warnings and special precautions for use and Pharmacokinetic
properties).
Concomitant therapy
The effect of CRESTOR on LDL-C and total-C may be enhanced when
used in combination with a bile acid binding resin. If CRESTOR is used
in combination with gemfibrozil, the dose of CRESTOR should be
limited to 10mg once daily.
