Description

Rosuvastatin is an inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase, the rate-limiting enzyme that converts 3-hydroxy-3-methylglutaryl coenzyme A to mevalonate, a precursor of cholesterol.

Indications

Rosuvastatin is indicated for- primary hypercholesterolaemia (type IIa including heterozygous familial hypercholesterolaemia), mixed dyslipidaemia (type IIb), or homozygousfamilial hypercholesterolaemia in patients who have not responded adequately to diet and other appropriate measures.

Dosage & Administration

Dose range: 5-40 mg once daily. Initially 5-10 mg once daily increased if necessary at intervals of at least 4 weeks to 20 mg once daily. Daily dose can be increased after further 4 weeks to 40 mg only in severe hypercholesterolaemia with high cardiovascular risk and under specialist supervision. Elderly initially 5 mg once daily.
HoFH: Starting dose 20 mg.
In pediatric patients 10 to 17 years of age with HeFH, the usual dose range is 5-20 mg/day; doses greater than 20 mg have not been studied in this patient population.
Use 40 mg dose only for patients not reaching LDL-C goal with 20 mg
Rosuvastatin can be taken with or without food, at any time of day.

Side Effects

Rosuvastatin is generally well tolerated. The adverse events seen with Rosuvastatin are generally mild and transient. Most commonly occurring side-effects are headache, myalgia, asthenia, constipation, dizziness, nausea, abdominal pain. Uncommonly pruritus, rash and urticaria may occur. Myopathy (including myositis), hypersensitivity reactions (including angioedema), rhabdomyolysis, pancreatitis etc are the rarely occurring side-effects of Rosuvastatin.

Precautions

Skeletal muscle effects (e.g., myopathy and rhabdomyolysis): Risks increase with use of 40 mg dose, advanced age (>65 year), hypothyroidism, renal impairment, and combination use with cyclosporine, lopinavir/ritonavir, atazanavir/ritonavir, or certain other lipid-lowering drugs. Patients should be advised to promptly report unexplained muscle pain, tenderness, or weakness. Rosuvastatin can be discontinued if signs or symptoms appear.
Liver enzyme abnormalities and monitoring: Persistent elevations in hepatic transaminases can occur. Liver enzymes should be monitored before and during treatment.

Use in Pregnancy & Lactation

Rosuvastatin 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, therapy should be discontinued and the patient apprised of the potential hazard to the fetus. Because of the potential for adverse reactions in nursing infants, women taking Rosuvastatin should not breast-feed.

Drug Interaction

Remarkable drug interactions of Rosuvastatin are-
Cyclosporine: Combination increases Rosuvastatin exposure. Rosuvastatin dose should be limited to 5 mg once daily.
Gemfibrosil: Combination should be avoided. If used together, Rosuvastatin dose should be limited to 10 mg once daily.
Lopinavir/Ritonavir or atazanavir/ritonavir: Combination increases Rosuvastatin exposure. Rosuvastatin dose should be to 10 mg once daily.
Coumarin anticoagulants: Combination prolongs international normalized ratio (INR). Stable INR should be achieved prior to starting Rosuvastatin. INR should be monitored frequently until stable upon initiation or alteration of Rosuvastatin therapy.
Concomitant lipid-lowering therapies: Use with fibrates and niacin products may increase the risk of skeletal muscle effects.

Use in special population
Age and sex: There was no clinically relevant effect of age or sex on the pharmacokinetics of Rosuvastatin in adults.
Race: Pharmacokinetic studies show an increase in exposure in Asian subjects compared with Caucasians.
Pregnancy and lactation: The safety of rosuvastatin during pregnancy and whilst breast feeding has not been established.
Severe renal impairment (not on hemodialysis): Starting dose is 5 mg, not to exceed 10 mg

Over Dose

There is no specific treatment in the event of overdose. In the event of overdose, the patient should be treated symptomatically and supportive measures instituted as required. Haemodialysis is unlikely to be of benefit.
