Tablets are pink, round or oval (40 mg), biconvex, film-coated, and imprinted with "ZD4522" and tablet strength.

Effects on cholesterol levels
The effects of rosuvastatin on LDL cholesterol are dose-related. At the 10mg dose, the average LDL cholesterol reduction was found to be 46% in one trial. Increasing the dose from 10 mg to 40 mg gave a modest increase of an additional 9% absolute reduction in LDL levels (55% below baseline levels).
