Lipitor 40mg is a higher-strength version of the widely prescribed cholesterol-lowering medication. It contains atorvastatin, a statin that effectively reduces LDL cholesterol, triglycerides, and non-HDL cholesterol while increasing HDL cholesterol. This medication is essential for patients with familial hypercholesterolemia or those who have not responded adequately to lower doses. Lipitor 40mg is taken orally once daily and is often part of a comprehensive treatment plan that includes dietary changes and regular exercise.
