How Hypercholesterolemia Medications Work

Hypercholesterolemia is a medical condition characterized by elevated levels of low-density lipoprotein (LDL) cholesterol in the blood. This can increase the risk of cardiovascular disease, including heart attacks and strokes.

Gold Standard: Statins (HMG-CoA Reductase Inhibitors)

Statins are considered the gold standard for treating hypercholesterolemia due to their efficacy in reducing LDL cholesterol levels. They work by inhibiting the enzyme HMG-CoA reductase, which is responsible for producing cholesterol in the liver.

• How Statins Work:

• Inhibit HMG-CoA reductase, reducing cholesterol production in the liver

• Decrease LDL cholesterol levels by up to 50%

• Also reduce triglyceride levels and increase high-density lipoprotein (HDL) cholesterol levels

Alternatives to Statins:

For patients who cannot tolerate statins or require additional treatment options, alternative medications are available. These include:

• Bile Acid Sequestrants:

• Bind to bile acids in the gut, reducing their reabsorption and increasing cholesterol excretion

• Fibrates:

• Increase lipolysis and reduce triglyceride levels

• PCSK9 Inhibitors:

• Block the PCSK9 enzyme, which regulates LDL receptor recycling in the liver
