Amiloride enhances the anticonvulsant action of various antiepileptic drugs in the mouse maximal electroshock seizure model.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Accumulating evidence indicates that amiloride (a potassium-sparing diuretic) exerts the anticonvulsant action in various in vivo and in vitro experiments. Therefore, the objective of this study was to assess the influence of amiloride on the protective action of numerous conventional and second-generation antiepileptic drugs [AEDs: carbamazepine (CBZ), lamotrigine (LTG), oxcarbazepine (OXC), phenobarbital (PB), topiramate (TPM), and valproate (VPA)] against maximal electroshock (MES)-induced seizures in mice. Results indicate that amiloride [up to 100 mg/kg, intraperitoneally (i.p.), at 30, 60, and 120 min before the test] neither altered the threshold for electroconvulsions, nor protected the animals against MES-induced seizures in mice. Moreover, amiloride (75 and 100 mg/kg, i.p., 120 min prior to the test) significantly enhanced the anticonvulsant effects of all studied AEDs, except for LTG, by reducing their ED(50) values in the MES test. In contrast, amiloride at 50 mg/kg (i.p.) had no significant effect on the antielectroshock action of the tested AEDs in mice. Estimation of total brain AED concentrations revealed that amiloride (75 mg/kg) significantly increased total brain concentrations of CBZ, OXC, and PB, but not those of LTG, TPM, and VPA in mice. In conclusion, one can ascertain that the potentiation of the antiseizure action of TPM and VPA by amiloride in the MES test and lack of any pharmacokinetic interactions between drugs, make the combinations of amiloride with TPM and VPA of pivotal importance for epileptic patients.
