Lipitor (atorvastatin) is a medication used to lower cholesterol levels in the body. The dosage of Lipitor that a person should take depends on various factors, such as their age, medical history, and cholesterol levels. The recommended starting dose of Lipitor is typically 10-20 mg per day, which can be increased to 40-80 mg per day if needed [2].

According to Drug Patent Watch [1], the maximum recommended dose of Lipitor is 80 mg per day. However, the actual dosage that a person needs may vary based on their individual circumstances. It is important to consult with a healthcare provider to determine the appropriate dosage for each person.

A study published in the Journal of Clinical Lipidology [3] found that reducing the dosage of atorvastatin from 40 mg to 20 mg per day was associated with a significant reduction in low-density lipoprotein (LDL) cholesterol levels. However, further reductions in dosage did not result in additional significant reductions in LDL cholesterol levels. This suggests that reducing the dosage of Lipitor may be effective in some cases, but the extent of the reduction may depend on the individual.

In conclusion, the recommended dosage of Lipitor typically ranges from 10-80 mg per day, with the maximum recommended dose being 80 mg per day. However, the actual dosage that a person needs may vary based on their individual circumstances. A reduction in dosage may be effective in some cases, but the extent of the reduction may depend on the individual. It is important to consult with a healthcare provider to determine the appropriate dosage for each person [1][2][3].
