Pravachol vs. Zetia

See how Pravachol and Zetia compare on approved uses, dosing, side effects, and cost.

Key Takeaways

  • Pravachol is a statin that blocks cholesterol production in the liver and has decades of data showing it lowers heart attack and stroke risk.

  • Zetia works differently, blocking cholesterol absorption in the gut, and is most often added to a statin like Pravachol for extra LDL lowering.

  • Both are once-daily oral tablets, but Pravachol offers two dose strengths for flexibility while Zetia comes in a single 10 mg dose.

Pravachol vs. Zetia Drug Summary

Pravachol

Pravachol (pravastatin) is a statin, or HMG-CoA reductase inhibitor, used to lower LDL cholesterol and reduce the risk of heart attack, stroke, and cardiovascular death. It is taken as one tablet by mouth once a day, usually in the evening, at a dose of 40 mg or 80 mg.

Zetia

Zetia (ezetimibe) is a cholesterol absorption inhibitor that lowers LDL cholesterol by blocking its uptake in the small intestine. It is taken as a single 10 mg tablet once a day, either on its own or combined with a statin for greater LDL reduction.

Pravachol vs. Zetia Indications

Pravachol

Pravachol is approved to lower LDL cholesterol and triglycerides in adults with high cholesterol. It also reduces the risk of heart attack, the need for artery-opening procedures, and cardiovascular death in people with or without existing heart disease.

  • Lowers LDL cholesterol and triglycerides in adults

  • Reduces risk of heart attack and cardiovascular death

  • Slows progression of coronary artery disease

  • Approved for children age 8 and older with familial high cholesterol

Zetia

Zetia is approved to lower LDL cholesterol in adults with high cholesterol, either alone or added to a statin. It is also used with fenofibrate for mixed high cholesterol and with a statin for certain inherited forms of very high cholesterol.

  • Lowers LDL cholesterol alone or added to a statin

  • Used with fenofibrate for mixed hyperlipidemia

  • Combined with a statin for homozygous familial hypercholesterolemia

  • Approved for children age 10 and older with heterozygous familial hypercholesterolemia

Pravachol vs. Zetia Pros and Cons

Pravachol

Pravachol has one of the longest safety track records of any statin, with large trials showing it cuts heart attacks and cardiovascular deaths. It is broadly available as a low-cost generic and covered by most insurance plans.

Pros

  • Decades of outcome data showing reduced heart attack and death risk

  • Fewer drug interactions than statins metabolized through CYP3A4

  • Two dose strengths allow adjustment based on LDL response

  • Widely covered generic with low copays

Cons

  • Muscle aches are a common reason patients stop taking it

  • Maximum LDL reduction is more modest than higher-intensity statins

  • Requires periodic liver enzyme monitoring

  • GI side effects like nausea and diarrhea are common

Zetia

Zetia works through a different pathway than statins, making it a useful add-on when a statin alone does not reach LDL goals. It is generally well tolerated on its own but carries added liver and muscle risks when combined with a statin.

Pros

  • Different mechanism adds LDL lowering on top of a statin

  • Option for patients who cannot tolerate statin side effects

  • Single 10 mg dose with no titration needed

  • Fewer muscle-related side effects when used alone

Cons

  • Modest LDL lowering when used by itself compared to statins

  • Not approved alone for homozygous familial hypercholesterolemia

  • Higher risk of liver enzyme elevation when paired with a statin

  • Less independent long-term heart attack outcome data than statins
