See the DrugPatentWatch profile for lipitor

Based on the information available, Lipitor (atorvastatin) is primarily used to lower cholesterol levels in the blood, not to directly affect blood pressure [1]. However, it can have an indirect effect on blood pressure by reducing the risk of heart disease and stroke [1].

The timeframe for noticing Lipitor's effects on cholesterol levels varies from person to person, but it typically takes about two to four weeks to see a significant reduction in LDL (bad) cholesterol levels [1][2].

As for its potential impact on blood pressure, it's important to note that Lipitor is not a first-line treatment for high blood pressure [1]. If a patient is taking Lipitor and sees a decrease in their blood pressure, it's likely due to the drug's beneficial effects on cardiovascular health rather than a direct effect on blood pressure [1].

In conclusion, while Lipitor is not primarily used to treat high blood pressure, it can have an indirect effect on blood pressure by reducing the risk of heart disease and stroke. The timeframe for noticing Lipitor's effects on cholesterol levels is typically two to four weeks, but the impact on blood pressure may not be immediately noticeable and could take several weeks or months to become apparent.
