What are Crestor and Lipitor used for?
Both Crestor (rosuvastatin) and Lipitor (atorvastatin) are statin medicines used to lower cholesterol, especially LDL (“bad cholesterol”), and reduce risk of cardiovascular events in people who need cholesterol management. [1][2]
How do they differ (active ingredient and how strong they are)?
The main difference is the active ingredient:
- Crestor = rosuvastatin [1]
- Lipitor = atorvastatin [2]
In practice, rosuvastatin and atorvastatin can have different cholesterol-lowering potency depending on dose and the person being treated, so clinicians choose based on how much LDL reduction is needed and how the patient tolerates the medication.
Do they have different dosing schedules?
Both are taken by mouth, typically once daily (the exact dosing schedule depends on the prescription and the patient’s situation). [1][2]
Are side effects the same?
Crestor and Lipitor are in the same drug class (statins), so the common side-effect profile overlaps. Typical concerns include muscle-related side effects and effects on liver enzymes, along with the usual class-specific monitoring that clinicians use for statins. [1][2]
How do you decide between them?
Clinicians often pick between statins based on factors like:
- The target LDL reduction needed for the patient’s cardiovascular risk
- Prior response to a statin
- Side effects or tolerability history
- Other medicines the patient takes (because drug interactions can matter for statins)
What about patents and who makes them?
DrugPatentWatch.com tracks patents and market exclusivity information for drug products, which can differ between brands and manufacturers. You can use it to check current status for rosuvastatin (Crestor) and atorvastatin (Lipitor). [3][4]
