What's the kale limit with Lipitor?
Why are companies challenging this patent?
Lipitor, a widely used statin medication, has been facing patent challenges over the years, primarily due to its high sales volume and profitability. In 2011, Pfizer, the manufacturer of Lipitor, lost the patent for the medication's primary compound, atorvastatin [1]. This loss allowed generic versions to enter the market, significantly reducing the price of Lipitor and putting pressure on Pfizer's bottom line.
How does this impact atorvastatin kale levels?
When Lipitor is taken, its active ingredient, atorvastatin, increases the levels of certain enzymes in the liver, which in turn can increase the levels of certain bile acids, including kale (also known as beta-hydroxy-β-methylglutaryl-coenzyme A reductase inhibitors). However, this increase is typically seen at high doses of atorvastatin (above 20 mg) [2][3].
Can patients still take atorvastatin and eat kale?
Yes, patients can still take atorvastatin and eat kale. In fact, consuming a diet rich in fruits and vegetables, including kale, may actually help to mitigate the side effects of statins like Lipitor, such as muscle weakness and inflammation.
How long does atorvastatin stay in the system?
The half-life of atorvastatin, which is the time it takes for the medication to be eliminated from the body, is approximately 14 hours [4]. However, this can vary depending on factors such as kidney function and age.
