Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

Mechanism of Action

Targets/IC₅₀/Ki	Sodium channel
In vitro	Rufinamide is extensively metabolised by non-CYP450 systems with a half-life of 8-12 hours. Its mechanism of action is thought to be inhibition of sodium-dependent action potentials in neurons, with possible membrane-stabilising effects. This compound hydrolysis is mediated primarily by human carboxylesterase (hCE) 1 and is nonsaturable up to 500 μM.
In vivo	Rufinamide given orally at 20 mg/kg every 12 h in healthy dogs should result in a plasma concentration and half-life sufficient to achieve the therapeutic level extrapolated from humans without short-term adverse effects in adult dogs. This compound alleviates injury-induced mechanical allodynia for 4 hours. It reduces peak current and stabilizes the inactivated state of voltage-gated sodium channel Nav1.7, with similar effects in dorsal root ganglion neurons in the Spared Nerve Injury neuropathic pain model in mice. This chemical suppresses pentylenetetrazol-induced seizures in mice (ED(50) 45.8 mg/kg) but not rats, and is active against MES-induced tonic seizures in mice (ED(50) 23.9 mg/kg) and rats (ED(50) 6.1 mg/kg). It suppresses pentylenetetrazol-, bicuculline-, and picrotoxin-induced clonus in mice (ED(50) 54.0, 50.5, and 76.3 mg/kg, respectively). This compound is partially effective in the mouse strychnine test.
