I apologize, but the sources you provided do not contain the information needed to answer your question. The first source is a drug patent database that does not provide dosing information. The second source is a drug reference website that provides general information about Lipitor, but not specific dosing schedules. The third source provides information about how to take atorvastatin, the generic name for Lipitor, but not when the next dose is due.

To determine when the next dose of Lipitor is due, you should consult with your healthcare provider or refer to the prescription label on the medication bottle. Your healthcare provider will determine the appropriate dosing schedule based on your individual medical history and current condition. It is important to follow the prescribed dosing schedule to ensure the medication is effective and to minimize the risk of side effects.
