描述 | Ethosuximide, 2-ethyl-2-methylsuccinimide, has been used extensively for "petit mal" seizures. Commonly observed side effects of ethosuximide are dose dependent and involve the gastrointestinal tract and central nervous system. The spontaneous pacemaker oscillatory activity of thalamocortical circuitry involves low threshold T-type Ca2+ currents in the thalamus, and ethosuximide is presumed to reduce these low threshold T-type Ca2+ currents in thalamic neurons. Ethosuximide also decreases the persistent Na+ and Ca2+ -activated K+ currents in thalamic and layer V cortical pyramidal neurons[3]. Ethosuximide and valproic acid are more effective than lamotrigine in the treatment of childhood absence epilepsy. Ethosuximide is associated with fewer adverse attentional effects[4]. Concentrations of 2 μM or more of Ethosuximide not only are found to be less effective than 1 μM concentration of Ethosuximide, but also induce cell toxicity. The number and percentage of tubulin β-III immunopositive neurons were increased after 6 days treatment with ethosuximide. Ethosuximide may compensate damage caused by seizure attacks and possibly other neuronal loss disorders[5]. Ethosuximide given with drinking water (300 mg/kg/day) over 45 days slightly reduced proneness to audiogenic epilepsy and increased locomotor activity of the animals at the periphery of the open field[6]. |
