Iloprost is a prostacyclin (PGI2) analog that binds with high affinity to IP, EP1 and EP3 receptors (Ki values are 11, 11, 56, 284, 619, 1035, 1870 and 6487 nM for IP, EP1, EP3, EP4, FP, DP, EP2 and TP receptors respectively). Iloprost inhibits platelet aggregation induced by collagen, thrombin and ADP (IC50 values are 0.24, 0.71 and 1.07 nM respectively).

| Body Surface Area (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
| Km factor | 3 | 6 | 12 | 8 | 5 | 20 |
| 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.
