How does a high fat diet impact lipitor's efficacy?

How does high fat intake change Lipitor absorption?

High-fat meals can reduce the rate of atorvastatin absorption from Lipitor tablets. Studies show peak plasma levels occur later and sometimes lower when taken with food, especially fatty food. This does not reduce the overall amount of drug absorbed over time.

When should you take Lipitor with meals?

The prescribing information states that Lipitor can be taken with or without food. No dose adjustment is needed based on food intake. Patients who experience stomach upset may prefer taking it in the evening with a light meal.

What changes if you eat a persistently high-fat diet?

A long-term high-fat diet does not alter the total amount of atorvastatin absorbed. It mainly affects the speed of absorption. The cholesterol-lowering effect remains consistent once steady-state levels are reached.

Why are companies challenging this patent?

The original atorvastatin patent expired in 2011. Since then, several manufacturers have challenged secondary patents covering specific formulations and polymorphs. Challenges continue on crystal forms and calcium salt versions of the drug.

When does Lipitor exclusivity expire?
