Lipitor vs. Vytorin
See how Lipitor and Vytorin compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Lipitor is a standalone statin, while Vytorin combines a statin with a cholesterol absorption inhibitor for added LDL lowering.
Both drugs are taken once daily as oral tablets, but Vytorin's simvastatin component carries stricter dose-related myopathy warnings.
Lipitor has been available generically since 2011, while Vytorin remains a brand-only fixed-dose combination.
Lipitor vs. Vytorin Drug Summary
Lipitor
Lipitor (atorvastatin) is an HMG-CoA reductase inhibitor, or statin, used to lower LDL cholesterol and reduce cardiovascular risk in adults and certain children. It is taken as a single oral tablet once daily, with doses ranging from 10 mg to 80 mg. It has been available generically since 2011.
Vytorin
Vytorin combines ezetimibe, a cholesterol absorption inhibitor, with simvastatin, a statin, in one tablet to lower LDL cholesterol more than either drug alone. It is taken once daily, with combined doses ranging from 10/10 mg to 10/80 mg. It remains available only as a brand-name combination product.

Lipitor vs. Vytorin Indications
Lipitor
Lipitor is FDA-approved to lower LDL cholesterol and triglycerides in adults and children age 10 and older with dyslipidemia. It also reduces the risk of heart attack, stroke, and certain heart procedures in adults with multiple cardiovascular risk factors, including those with type 2 diabetes. It is approved for both heterozygous and homozygous familial hypercholesterolemia.
Lowers LDL cholesterol and triglycerides in adults and children 10+
Reduces heart attack and stroke risk in high-risk adults
Reduces cardiovascular risk in adults with type 2 diabetes
Treats homozygous and heterozygous familial hypercholesterolemia
Vytorin
Vytorin is FDA-approved to lower LDL cholesterol, total cholesterol, triglycerides, and Apo B in adults with primary hyperlipidemia, while also raising HDL. It is approved for homozygous familial hypercholesterolemia and homozygous sitosterolemia. In the IMPROVE-IT trial, it reduced major cardiovascular events compared with simvastatin alone in patients after a heart attack or unstable angina.
Lowers LDL, total cholesterol, triglycerides, and Apo B
Raises HDL cholesterol in adults with hyperlipidemia
Treats homozygous familial hypercholesterolemia
Treats homozygous sitosterolemia
Lipitor vs. Vytorin Pros and Cons
Lipitor
Lipitor is a well-studied, single-ingredient statin with decades of safety data and no boxed warning. As a generic, it is widely covered by insurance and available at low out-of-pocket cost. Because it works through one mechanism, dosing decisions are more straightforward than with combination therapy.
Pros
More than two decades of real-world safety data
No boxed warning, unlike some other lipid therapies
Single-ingredient dosing is simpler to adjust
Approved for use in children as young as 10
Cons
Works through only one cholesterol-lowering pathway
Higher doses carry increased myopathy risk
Not approved for sitosterolemia or Apo B lowering claims
May need higher doses for maximal LDL reduction
Vytorin
Vytorin combines two cholesterol-lowering mechanisms in one tablet, which can produce greater LDL reduction than a statin alone, especially in patients who don't reach goal on a statin by itself. It carries additional restrictions, including contraindication with strong CYP3A4 inhibitors and a capped simvastatin dose due to myopathy risk. As a brand-only combination, it is not available as a generic fixed-dose product.
Pros
Combines two mechanisms for greater LDL lowering
Backed by the IMPROVE-IT cardiovascular outcomes trial
Also approved for homozygous sitosterolemia
Single tablet combines two drug classes
Cons
Not available as a generic fixed-dose combination
Contraindicated with strong CYP3A4 inhibitors
80 mg simvastatin dose restricted due to myopathy risk
Higher risk of hypersensitivity reactions like angioedema
