Pregabalin is a new anticonvulsant therapy which holds promise as a safe and effective adjunct drug for seizure control in epileptic dogs that respond poorly to standard drugs such as phenobarbital or potassium bromide[1].

It is use primarily for idiopathic epilepsy but also has a role in modulating neuropathic pain[2].

It is considered a next generation gabapentin which acts to reduce calcium influx and release of glutamate, an excitatory neurotransmitter[3].

At doses of 3 - 4 mg/kg orally every 8 - 12 hours it appears to have few side effects and is effective in idiopathic epilepsy[4]. Sedation is the most common side effect.
