Based on the information provided, I was unable to find a specific timeframe for how quickly Lipitor (atorvastatin) lowers resting heart rate. Lipitor is a type of drug known as a statin, which is primarily used to lower cholesterol levels in the blood [1].

However, some studies have suggested that statins may have a modest effect on heart rate. A review of several clinical trials found that statins reduced heart rate by about 1 beat per minute, on average [2]. It is important to note that this effect is not immediate and may take several weeks or even months to become apparent [3].

It's also worth mentioning that Lipitor is not typically prescribed specifically to lower resting heart rate. If you have concerns about your heart rate, you should speak with your healthcare provider. They can recommend appropriate treatments and lifestyle changes based on your individual needs and medical history.

In summary, while Lipitor may have a modest effect on heart rate, it is not a primary indication for this drug. The effect on heart rate may take several weeks or months to become apparent. If you have concerns about your heart rate, you should speak with your healthcare provider.
