Indications

• Rostab is indicated for:
• Patients with primary hyperlipidemia and mixed dyslipidemia as an adjunct to diet to reduce elevated total-C, LDL-C, ApoB, non HDL-C and TG levels and to increase HDL-C.

Pharmacology

• Rosuvastatin is a selective and competitive inhibitor of HMG-CoA reductase, the rate-limiting enzyme that converts 3-hydroxy-3-methyl glutaryl coenzyme A to mevalonate, a precursor of cholesterol. Rosuvastatin produces its lipid-modifying effects in two ways. First, it increases the number of hepatic LDL receptors on the cell surface to enhance uptake and catabolism of LDL. Second, Rosuvastatin inhibits hepatic synthesis of VLDL, which reduces the total number of VLDL and LDL particles.

Dosage & Administration

• Heterozygous Familial Hypercholesterolemia in Pediatric Patients (10 to 17 years of age): The usual dose range of Rosuvastatin is 5-20 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. Adjustments should be made at intervals of 4 weeks or more.

• Very High Cholesterol and High Risk of Ml or Stroke: 40 mg once daily.

• Homozygous Familial Hypercholesterolemia: The recommended starting dose of Rosuvastatin is 20 mg once daily. Response to therapy should be estimated from preapheresis LDL-C levels.

• Dosage in Asian Patients: Initiation of Rosuvastatin therapy with 5 mg once daily should be considered for Asian patients

• Use with Cyclosporine, Lopinavir/Ritonavir or Atazanavir/Ritonavir: In patients taking Cyclosporine, the dose of Rosuvastatin should be limited to 5 mg once daily. In patients taking a combination of Lopinavir and Ritonavir or Atazanavir and Ritonavir, the dose of Rosuvastatin should be limited to 10 mg once daily.

• Concomitant Lipid-Lowering Therapy: The risk of skeletal muscle effects may be enhanced when Rosuvastatin is used in combination with Niacin or Fenofibrate; a reduction in Rosuvastatin dosage should be considered in this setting. Combination therapy with Gemfibrozil should be avoided because of an increase in Rosuvastatin exposure with concomitant use; if Rosuvastatin is used in combination with Gemfibrozil, the dose of Rosuvastatin should be limited to 10 mg once daily.

• Dosage in Patients with Severe Renal Impairment: For patients with severe renal impairment (ClCr<30 mL/min/1.73 m²) not on hemodialysis, dosing of Rosuvastatin should be started at 5 mg once daily and not exceed 10 mg once daily.

Interaction

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

Contraindications

• Rosuvastatin is contraindicated if-
• Known hypersensitivity to product components
• Liver disease, which may include unexplained persistent elevations in hepatic transaminase levels
• Pregnant women and women who may become pregnant
• Nursing mothers

Side Effects

• Rostab is generally well tolerated. The most frequent adverse events thought to be related to Rostab were headache, myalgia, constipation, asthenia, abdominal pain and nausea.

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 immediately. It is not known whether Rosuvastatin is excreted in human milk, but a small amount of another drug in this class does pass into breast milk.

Precautions & Warnings

• Rostab should be prescribed with caution in patients with predisposing factors for myopathy (e.g., age >65 years, inadequately treated hypothyroidism, renal impairment). The risk of myopathy during treatment with Rostab may be increased with concurrent administration of some other lipid-lowering therapies (Fibrates or Niacin), Gemfibrozil, Cyclosporine, Lopinavir/Ritonavir, or Atazanavir/Ritonavir. Rostab therapy should be discontinued if markedly elevated creatinine kinase levels occur or myopathy is diagnosed or suspected. Rostab therapy should also be temporarily withheld in any patient with an acute, serious condition suggestive of myopathy or predisposing to the development of renal failure secondary to rhabdomyolysis (e.g., sepsis, hypotension, dehydration, major surgery, trauma, severe metabolic, endocrine, and electrolyte disorders, or uncontrolled seizures). It is recommended that liver enzyme 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.

Overdose Effects

• 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. Hemodialysis does not significantly enhance clearance of Rostab.

Therapeutic Class

• Other Anti-anginal & Anti-ischaemic drugs, Statins

Storage Conditions

• Keep below 30oC temperature, protected from light & moisture. Keep out of the reach of children.
