To determine if control of seizures and survival are still possible without pretreatment or immediate pharmacologic intervention , we studied the anticonvulsant efficacy of the GluK1 ( GluR5 ) / alpha - amino - 3 - hydroxy - 5 - methyl - 4 - isoxazolepropionic acid ( AMPA ) receptor antagonist ( 3S , 4aR , 6R , 8aR ) - 6 - [ 2 - ( 1 ( 2 ) H - tetrazole - 5 - yl ) ethyl ] decahydroisoquinoline - 3 - carboxylic acid ( LY293558 ) in rats that did not receive any treatment until 20 minutes after exposure to the nerve agent soman .
 alpha - amino - 3 - hydroxy - 5 - methyl - 4 - isoxazolepropionic acid, AMPA, ( 3S , 4aR , 6R , 8aR ) - 6 - [ 2 - ( 1 ( 2 ) H - tetrazole - 5 - yl ) ethyl ] decahydroisoquinoline - 3 - carboxylic acid, LY293558
