The first source, Drug Patent Watch [1], provides information about the drug itself, but does not mention anything about tapering schedules.

The second source, a study published in the Journal of Clinical Pharmacology [2], discusses the pharmacokinetics of atorvastatin (the active ingredient in Lipitor) and its metabolites. The study does not provide any information about tapering schedules.

The third source, Reuters [3], discusses the Federal Reserve's plan to reduce its bond-buying program, known as tapering. This is unrelated to Lipitor and does not provide any information about tapering schedules for the medication.
