Zonisamide sodium salt is an antiepileptic compound. It is effective in various animal models of epilepsy and in humans with partial and systemic seizures. Zonisamide sodium also removes nitric oxide (NO).

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.
