How often did Lipitor (atorvastatin) raise liver enzymes in clinical studies?
In the information provided here, there isn’t any data on how frequently liver enzymes rose on Lipitor, so the exact rate can’t be stated.
What “liver enzymes rise” usually refers to with Lipitor
With statins, “liver enzymes rise” typically means increases in alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST), which are markers of liver inflammation or injury. The frequency varies by study design and how “clinically meaningful” elevations are defined (for example, mild vs. marked elevations).
What to check to find the exact frequency
To answer with a specific percentage, you’d normally look in Lipitor’s prescribing information for:
- The trial adverse-event tables (ALT/AST increases by frequency)
- Definitions like “elevations >3x ULN” (upper limit of normal) or discontinuation rates due to liver enzyme increases
If you share a label section, I can extract the number
If you paste the relevant part of the Lipitor label (or tell me which document/version you’re using), I can identify the exact reported frequency and the ALT/AST threshold used.
