Pravadoline (WIN 48098) is an antiinflammatory and analgesic compound with an IC50 of 4.9 uM for inhibition of the synthesis of prostaglandins (PGs) in mouse brain. Pravadoline (WIN 48098) is related in structure to non-steroidal antinflammtory agents such as indometacin. Pravadoline (WIN 48098) was developed in the 1980s as a new antiinflammatory and prostaglandin synthesis inhibitor, acting through inhibition of the enzyme cyclooxygenase (COX).

Weight (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
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.
