The effect of acetyldexphenmetrazine and dexphenmetrazine on the susceptibility to audiogenic seizures in mice.

The antiepileptic effect of dexphenmetrazine (DP) and acetyldexphenmetrazine (ADP) was tested on audiogenic seizures in a 100% susceptible strain of mice. DP had no antiepileptic effect, however, it markedly suppressed the postparoxysmal motor inhibition. ADP had a distinct anticonvulsive effect--it suppressed the convulsive component of the seizure, leaving its running component unaffected. The results are compared with the effect of both drugs on electrographic epileptic phenomena in the turtle brain (Servít and Strejcková 1976).

The effect of dexphenmetrazine and acetyldexphenmetrazine upon epileptic electrographic activities in the brain of the turtle.

The effect of acetyldexphenmetrazine (ADP) and dexphenmetrazine (DP) on normal and epileptic electrographic activities in the cortical and thalamic structures of the turtle brain were studied in curarized and artificially ventilated animals. Both drugs almost exclusively influenced cortical activities. The effect of low doses of ADP and DP was similar--they desynchronized cortical activity and suppressed the activity of a cortical penicillin focus. They also elevated the cortical response to optic stimuli. Higher doses of ADP continued to suppress both normal and epileptic cortical activities. Higher doses of DP had a two phase effect with enhancement of epileptic activity in the first phase. Continuous trains of theta activity appeared after low doses of ADP and very often after both low and high doses of DP. The findings are discussed in terms of comparative physiology of the brain.
