According to [1] the medication guide for Lipitor (Atorvastatin Calcium) provided by the manufacturer, Pfizer, and the National Institutes of Health, the typical dosage and administration of Lipitor for best results depends on the individual patient's need and condition.

The standard recommended dosage for most adults to lower cholesterol levels is 10-80 mg per day [1]. For patients with severe hyperlipidemia or who require a more significant reduction in cholesterol levels, higher doses of 80-120 mg per day may be prescribed.

It's essential to note that the dosage and administration of Lipitor should be individualized and determined by a healthcare professional. They will assess the patient's specific needs, medical history, and other factors to determine the most effective dosage and treatment frequency.

Typically, Lipitor is taken once daily in the evening, with or without food [1]. However, it's crucial to follow the specific dosing instructions provided by the healthcare professional and to take the medication as prescribed.

In some cases, the healthcare professional may need to adjust the dosage or administration frequency based on the patient's response to the treatment. It's essential to work closely with a healthcare professional to ensure the optimal dosage and treatment plan for achieving the best results.
