Propylparaben
(
PPB
) induces cardioprotection after ischemia-reperfusion injury by inhibiting voltage-dependent Na
+
channels. The present study focuses on investigating whether the i.p. application of 178mg/kg
PPB
after pilocarpine-induced
status epilepticus
(SE) reduces the acute and long-term consequences of seizure activity. Initially, we investigated the effects of a single administration of
PPB
after SE. Our results revealed that compared to rats receiving diazepam (DZP) plus vehicle after 2h of SE, animals receiving a single dose of
PPB
1h after DZP injection presented 126% (p<0.001) lower extracellular levels of glutamate in the hippocampus. This effect was associated with an increased potency of low-frequency oscillations (0.1-13Hz bands, p<0.001), a reduced potency of 30-250Hz bands (p<0.001) and less neuronal damage in the hippocampus. The second experiment examined whether the subchronic administration of
PPB
during the post-SE period is able to prevent the long-term consequences of seizure activity. In comparison to animals that were treated subchronically with vehicle after SE, rats administered with
PPB
for 5 days presented lower hippocampal excitability and interictal glutamate release, astrogliosis, and neuroprotection in the dentate gyrus. Our data indicate that
PPB
, when applied after SE, can be used as a therapeutic strategy to reduce the consequences of seizure activity.
