According to the sources provided, it is not recommended to split Lipitor (atorvastatin) doses throughout the day. Lipitor is a medication used to lower cholesterol levels in the blood, and it should be taken as directed by a healthcare provider. The drug is available in different strengths, and the recommended dose is usually once a day, with or without food [3].

The drug label for Lipitor advises that the tablet should be swallowed whole and not crushed, chewed, or divided [3]. Pill splitting is a practice where patients cut pills in half or quarters to save money on medication costs. However, pill splitting is not recommended for all medications, and it can be dangerous if not done correctly. According to GoodRx, Lipitor is not recommended for pill splitting because the tablets are film-coated and scored, which means they are not designed to be divided [2].

Furthermore, the drug patent watch website confirms that the patent for Lipitor expired in 2011, and there are now generic versions of the drug available on the market. However, this does not change the fact that the medication should be taken as directed by a healthcare provider [1].

In summary, splitting Lipitor doses throughout the day is not recommended. Patients should take the medication as directed by their healthcare provider, usually once a day, with or without food. Lipitor tablets should be swallowed whole and not divided, according to the drug label. Pill splitting is not recommended for Lipitor because the tablets are not designed to be divided. Patients should consult with their healthcare provider or pharmacist if they have any questions or concerns about their medication regimen.
