What is the route of administration for atorvastatin?

Atorvastatin is administered orally, making this the correct choice. As a statin, it is primarily used to lower cholesterol levels in the blood to help prevent cardiovascular diseases. The oral route allows it to be absorbed through the gastrointestinal tract, leading to systemic circulation where it can exert its effects on lipid metabolism. This route is convenient and widely accepted for medications that need to be taken on a regular basis, aligning well with the chronic condition management that atorvastatin addresses.

Other routes, such as intravenous or subcutaneous, are typically reserved for medications that require rapid onset or specific therapeutic mechanisms, while topical administration is suited for local effects on the skin or mucous membranes. However, atorvastatin's desired effects are systemic rather than local, reinforcing why the oral route is the most appropriate method for its administration.
