Lipitor (atorvastatin) is a medication used to lower cholesterol levels in the body. According to the sources provided, the timing of Lipitor intake does not seem to matter significantly.

The drug patent watch website [1] does not provide any information on the timing of Lipitor intake. However, the Mayo Clinic [2] suggests that Lipitor can be taken with or without food, and at any time of the day. It is important to take Lipitor regularly, at the same time each day, to maintain consistent levels of the medication in the body.

GoodRx [3] also confirms that Lipitor can be taken at any time of the day, but suggests that it may be more convenient to take it at night, as the body naturally produces more cholesterol at night. However, this recommendation is not based on any clinical evidence and is not a requirement for the medication to be effective.

In conclusion, based on the sources provided, it appears that the timing of Lipitor intake is not a significant factor in its effectiveness. It can be taken at any time of the day, with or without food, as long as it is taken regularly at the same time each day. However, patients should always follow the instructions of their healthcare provider regarding the proper use of Lipitor and any other medications they are taking.
