The anticonvulsant effect of carbamazepine (CBZ) was examined in 10-, 18- and 25-day-old Wistar albino rats into which bicuculline or pentylenetetrazol had been systemically injected to induce generalized epileptic manifestations typical for the specific age of the animals. The results showed that: a) in developing rats, CBZ appears to be more effective in the pentylenetetrazol than the bicuculline model of epilepsy; b) in both models of epilepsy the efficacy of CBZ increases with the age of the animals; and c) among the various epileptic manifestations, the tonic phase is the most sensitive to the anticonvulsant effect of CBZ. These conclusions are correlated with the different levels of cerebral maturation of the animals, and are discussed with reference to the mechanisms of action of CBZ and bicuculline or pentylenetetrazol.

D010433 Pentylenetetrazole A pharmaceutical agent that displays activity as a central nervous system and respiratory stimulant. It is considered a non-competitive GAMMA-AMINOBUTYRIC ACID antagonist. Pentylenetetrazole has been used experimentally to study seizure phenomenon and to identify pharmaceuticals that may control seizure susceptibility.

D002220 Carbamazepine A dibenzazepine that acts as a sodium channel blocker. It is used as an anticonvulsant for the treatment of grand mal and psychomotor or focal SEIZURES. It may also be used in the management of BIPOLAR DISORDER, and has analgesic properties.

D004827 Epilepsy A disorder characterized by recurrent episodes of paroxysmal brain dysfunction due to a sudden, disorderly, and excessive neuronal discharge. Epilepsy classification systems are generally based upon: (1) clinical features of the seizure episodes (e.g., motor seizure), (2) etiology (e.g., post-traumatic), (3) anatomic site of seizure origin (e.g., frontal lobe seizure), (4) tendency to spread to other structures in the brain, and (5) temporal patterns (e.g., nocturnal epilepsy).
