Lipitor is a medication used to lower cholesterol levels in the blood, which can help reduce the risk of heart disease and stroke. The recommended dosage of Lipitor may vary depending on the patient's age, medical history, and other factors. However, the sources provided do not mention any specific dosages for seniors.

According to DrugPatentWatch [1], the recommended starting dose of Lipitor is 10 or 20 mg once daily for most adults. However, the dosage may be increased up to 80 mg once daily for patients who require additional cholesterol-lowering effects. The dosage should be adjusted based on the patient's response to the medication and any potential side effects.

A study published in the Journal of Geriatric Cardiology [2] suggests that Lipitor is safe and effective for use in older adults, including those over the age of 75. The study found that Lipitor significantly reduced cholesterol levels and was well-tolerated in older adults.

Healthline [3] notes that Lipitor should be used with caution in patients with liver or kidney disease, as well as those over the age of 65. The dosage may need to be adjusted based on the patient's kidney function.

In conclusion, while there is no specific dosage of Lipitor recommended for seniors, the medication is considered safe and effective for use in older adults. The dosage should be adjusted based on the patient's individual needs and response to the medication, as well as any potential side effects or medical conditions.
