Simvastatin 20mg Tablet Uses
Simvastatin 20mg tablet is prescribed to:
- Lower high levels of LDL cholesterol and triglycerides in the blood.
- Increase HDL cholesterol levels to support cardiovascular health.
- Reduce the risk of heart attack, stroke, and other cardiovascular complications in patients with high cholesterol or existing heart disease.

How Does Simvastatin 20mg Tablet Work
Simvastatin works by inhibiting HMG-CoA reductase, an enzyme involved in cholesterol production in the liver. By reducing cholesterol synthesis, Simvastatin lowers LDL and triglyceride levels while promoting HDL cholesterol. This helps prevent plaque buildup in arteries, improving overall heart and vascular health.

Simvastatin 20mg Dosage
Simvastatin 20mg is usually prescribed to lower cholesterol and triglyceride levels, helping to reduce the risk of heart disease and stroke. The typical starting dose for adults with high cholesterol is 10mg to 20mg once daily, taken in the evening. Patients at higher cardiovascular risk may require up to 40mg per day, but higher doses are generally avoided due to increased side effects. For children aged 10-17 with familial hypercholesterolemia, the usual dose starts at 10mg daily, with a maximum of 40mg per day under medical supervision. The tablet should be taken once daily, preferably in the evening, with or without food. It should be swallowed whole with water, and missed doses should not be doubled.

Mechanism of Action of Simvastatin 20mg
Simvastatin 20mg belongs to a class of drugs called statins (HMG-CoA reductase inhibitors). It works by blocking the enzyme HMG-CoA reductase, which is responsible for producing cholesterol in the liver. By inhibiting this enzyme, Simvastatin reduces the production of low-density lipoprotein (LDL) cholesterol, commonly known as “bad cholesterol,” while increasing high-density lipoprotein (HDL) cholesterol or “good cholesterol.”
Additionally, Simvastatin helps lower triglyceride levels, reducing the overall risk of heart disease, stroke, and other cardiovascular conditions. Its effects lead to a decrease in plaque buildup in arteries, improving blood flow and lowering the risk of complications related to high cholesterol. The medication takes a few weeks to show full effects, and long-term use is recommended for sustained cholesterol management.

- Avoid excessive alcohol consumption, as it may increase the risk of liver damage.
