Losigamone is an investigational drug for the treatment of epilepsy. It has been studied as an add-on treatment for partial seizures.[1] Phase III clinical trials were conducted around the year 2000.[2]

Mechanism of action

The mechanism of action is not known. Data regarding the interaction of losigamone with GABA receptors are inconsistent: it increases GABA-induced chloride influx in spinal cord neuron cultures, but has no significant influence on GABAergic inhibitory postsynaptic potentials in hippocampal slices.[2] Interaction with potassium[2] and sodium channels[3] has been proposed.
