Atorvastatin hemicalcium (CI-981) is an orally active inhibitor of HMG-CoA reductase used as a cholesterol-lowering medication that blocks the production of cholesterol. Atorvastatin hemicalcium inhibits human SV-SMC proliferation and invasion with IC50s of 0.39 μM and 2.39 μM, respectively.

| Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
| Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
