Retigabine is a first-in-class K+ channel (KCNQ) opener. KCNQ channels are reported to be expressed predominantly in neurons and are critical determinants of cellular excitability, as shown by the occurrence of human genetic mutations in KCNQ channels which underlie inheritable disorders including the syndrome of benign familial neonatal convulsions.
In vitro: Retigabine was found to combine a novel mode of actions, which were namely potassium channel opening (KCNQ2, KCNQ3 as well as KCNQ4 channels). Retigabine also showed activities with some potentiation of gamma amino butyric acid (GABA)-evoked currents at its higher concentrations [1].
In vivo: Animal models of epileptic seizures showed that retigabine treatment was effective at an oral dose as low as 0.01 mg/kg. Studies performed in mice also indicated that combining retigabine with another anticonvulsant agent leads to an additive effect [1].
Clinical trial: A clinical interaction study showed that there was no pharmacokinetic interaction between phenobarbitone and retigabine in healthy subjects. Thus, no dosage adjustment is likely to be necessary when phenobarbitone and retigabine are coadministered to patients [1].
