Rosuvastatin Calcium

Rosuvastatin Calcium is a prescription medication in the class of drugs called HMG-CoA reductase inhibitors (statins). This medication is used to lower triglyceride and cholesterol levels in the blood. By reducing low-density lipoprotein (LDL) cholesterol and increasing HDL (high-density lipoprotein) cholesterol, Rosuvastatin helps reduce the risk of cardiovascular events.

Rosuvastatin Calcium (Crestor) is a statin FDA-approved for the following medical uses:

Primary Hyperlipidemia (including Heterozygous Familial Hypercholesterolemia):

• Used as an adjunct to diet to reduce elevated total cholesterol, LDL cholesterol (bad cholesterol), triglycerides, and apolipoprotein B, and to increase HDL cholesterol (good cholesterol) in adults and pediatric patients (ages 8 to 17 years).

Homozygous Familial Hypercholesterolemia (HoFH):

• Used to reduce LDL cholesterol and total cholesterol levels in adults with this inherited condition, either alone or together with other lipid-lowering treatments.

Hypertriglyceridemia:

• Indicated as an adjunct to diet to lower elevated triglyceride levels in adults.

Primary Dysbetalipoproteinemia (Type III Hyperlipoproteinemia):

• Used in adults who do not respond adequately to diet alone to improve abnormal cholesterol levels.

Atherosclerosis (Slowing Disease Progression):

• Used to slow the progression of atherosclerosis as part of a cholesterol-lowering treatment plan in adults with coronary heart disease.

Primary Prevention of Cardiovascular Events:

• Used to reduce the risk of heart attack (myocardial infarction), stroke, and arterial revascularization procedures in adults without established coronary heart disease but with multiple cardiovascular risk factors.

Rosuvastatin Calcium works by inhibiting HMG-CoA reductase, an enzyme in the liver responsible for producing cholesterol. This enzyme plays a key role in the conversion of HMG-CoA to mevalonate, an early & rate-limiting step in cholesterol synthesis. By blocking this enzyme, Rosuvastatin:

• Reduces the production of (LDL) low-density lipoprotein (“bad” cholesterol)
• Decreases total cholesterol and triglyceride levels
• Increases high-density lipoprotein (HDL) cholesterol (“good” cholesterol)
• Enhances the liver’s uptake and breakdown of LDL from the bloodstream

Lowering LDL cholesterol helps reduce the buildup of fatty deposits (plaques) in the arteries, thereby decreasing the risk of heart attack and other cardiovascular complications.

Your Rosuvastatin Calcium dose depends on your condition, cholesterol levels, and other health factors. Always follow your doctor-prescribed dosage regimen.

Rosuvastatin Calcium Dosage for Adults

Rosuvastatin Calcium Dosage for Pediatric Patients

You must follow these administration guidelines for effective use of Rosuvastatin Calcium tablets:

• This tablet can be taken with or without food.
• Swallow the Rosuvastatin Calcium tablet with water.
• Try to take this medication at the same time every day for consistent blood levels.
• Do not crush or chew the tablets.
• Continue taking the medication even if you feel well, as high cholesterol often has no symptoms.
• Follow your doctor’s recommendations regarding diet, exercise, and lifestyle changes while using this medication.

Always follow the prescribing information for Rosuvastatin Calcium (Crestor) and consult your healthcare provider if you miss a dose or have questions about your treatment.

Skeletal Muscle Effects (Myopathy and Rhabdomyolysis)

• Rosuvastatin may cause muscle pain, tenderness, or weakness. In rare cases, it may lead to rhabdomyolysis, a serious condition that might result in kidney failure. Risk is higher with:
  • Higher doses (especially 40 mg)
  • Advanced age (≥65 years)
  • Renal impairment
  • Hypothyroidism
  • Concomitant use of interacting drugs (e.g., cyclosporine, gemfibrozil)
• Patients should report unexplained muscle pain, weakness, or dark urine immediately.

Liver Enzyme Abnormalities

• Persistent elevations in liver enzymes (ALT/AST) have been reported. Liver function tests should be performed before starting your treatment and when clinically indicated thereafter.

Proteinuria and Hematuria

• Dipstick-positive protein and blood in urine have been observed, particularly at higher doses. These effects are usually transient and not associated with worsening kidney function.

Risk in Pregnancy

• Rosuvastatin may cause harm to the fetus. Discontinue Rosuvastatin once pregnancy is recognized, unless the benefits of treatment outweigh the potential risks in a patient at very high risk of cardiovascular events.

Here are some important precautions you should consider when taking Rosuvastatin Calcium:

• Use caution in patients who consume substantial amounts of alcohol or who have a history of liver disease.
• Monitor patients with risk factors for muscle toxicity.
• Patients with severe renal impairment require lower starting doses.
• Asian patients may have increased drug exposure and may require dose adjustments.
• Rosuvastatin may slightly increase blood sugar levels in some patients.

Do not use Rosuvastatin Calcium if you:

• Have active liver disease, particularly unexplained persistent elevations in liver enzymes.
• Are pregnant.
• Are breastfeeding.
• Have a known hypersensitivity to Rosuvastatin or any component of the formulation.

Taking more than the prescribed dose of Rosuvastatin Calcium may increase the risk of serious side effects, particularly muscle toxicity and liver enzyme abnormalities.

Possible Symptoms of Rosuvastatin Overdose

• Muscle pain, tenderness, or weakness
• Dark-colored urine (possible sign of rhabdomyolysis)
• Severe fatigue
• Nausea or vomiting
• Abdominal pain
• Elevated liver enzymes (may not cause immediate symptoms)

There is no specific antidote for Rosuvastatin overdose. Treatment is supportive and based on symptoms. If you think you have taken too much Rosuvastatin Calcium, seek immediate medical attention or contact your local poison control center.

Here are the recommended storage conditions for Rosuvastatin Calcium tablets to keep the medication safe:

• These tablets should be kept away from moisture and direct light.
• Always keep the tablets in their original container with the lid tightly closed.
• Ensure it is out of reach of children and pets.
• Do not use the Rosuvastatin tablets after the expiration date.
