Popis: In experiments on 52 freely moving Wistar male rats, 200-220 g in weight, on the model of focal penicillin-induced epileptic activity (EpA) in brain cortex the efficacy of combined application of drugs influencing different mechanisms of epileptogenesis: sodium valproate enhancing GABA-ergic processes, and the calcium antagonist ryodipine (1,4-dihydropyridine) have been studied. It was shown that valproate and ryodipine when used in combination at relatively small doses (150 and 0.8 mg/kg l.p., respectively) produced a more marked antiepileptic effect than each of these drugs given alone. These and previously reported results of studies on the model of generalized pentylenetetrazol-induced EpA, suggest that complex pathogenic therapy (CPT) as a combination of the antiepileptic drugs acting on the corresponding basic pathogenic mechanisms of respective form of epilepsy is reasonable to be used. CPT allows to obtain a better curative effect with a lower dose of each drug used and to reduce the risk of side effects of the drugs applied at large doses in case of monotherapy.
