Atorvastatin calcium, a widely prescribed statin medication, plays a crucial role in managing lipid levels and reducing the risk of cardiovascular disease. It works by inhibiting the enzyme HMG-CoA reductase, which is responsible for cholesterol synthesis in the liver. This inhibition leads to a decrease in low-density lipoprotein (LDL) cholesterol, often referred to as “bad cholesterol,” while potentially increasing high-density lipoprotein (HDL) cholesterol, known as “good cholesterol.”
Atorvastatin calcium is commonly prescribed for patients with high cholesterol, particularly those with a history of heart disease or at high risk for cardiovascular events. Its effectiveness in lowering cholesterol levels has been well-established through numerous clinical trials, making it a cornerstone of lipid management strategies.
Dosage and Administration
Atorvastatin calcium is typically administered orally, and the dosage is determined based on the individual’s condition and response to treatment. The recommended starting dose for most patients is 10 mg once daily. However, the dosage may be adjusted based on the patient’s response and tolerance.
Dosage Range
The typical dosage range for atorvastatin calcium is 10 to 80 mg once daily.
| Dosage Range | Indication |
|---|---|
| 10-40 mg once daily | Hypercholesterolemia, primary prevention of cardiovascular disease |
