Approved drug PDB Ligand
retigabine is an approved drug (FDA and EMA (2011))
Compound class: Synthetic organic
Comment: Retigabine is unique among antiepileptic drugs in that it functions by activating selected voltage-gated potassium channels in the brain (i.e. Kv7 family channels) [3] [4].

Summary of Clinical Use Click here for help
Retigabine was approved to treat intractable partial-onset epileptic seizures. Use of retigabine was discontinued in 2017 due to serious side-effects including urinary retention, blue skin, and retinal discoloration. The poor selectivity of retigabine among Kv7.2-Kv7.5 channels, and issues around its metabolic degradation products are considered to contribute to these adverse events. Channel activators with improved selectivity for Kv7.2/Kv7.3 are being developed and investigated [2].
Mechanism Of Action and Pharmacodynamic Effects Click here for help
Retigabine acts as a neuronal voltage activated potassium channel opener but may also affect inhibitory GABA neurotransmission by the GABAA receptor. See the DrugBank link for further details.
