Lay summary

Chronic pain causes substantial suffering and disability worldwide. Several studies have shown that two-fifths of the UK population live with pain that has lasted for three months or longer. The National Institute for Health and Care Excellence (NICE) recommends that clinicians consider several other medicines classes before considering opioids for patients with chronic non-cancer pain. Recent research has highlighted the increase in gabapentinoid (gabapentin and pregabalin) use in pain management.

Technical summary

In the UK, gabapentin was licensed as an adjunct antiepileptic therapy for partial seizures and treating focal seizures in 1993. In 2000, gabapentin gained its approval as an analgesic for managing neuropathic pain and postherpetic neuralgia. Pregabalin was licensed in 2004 for treating neuropathy, postherpetic neuralgia, as an add-on drug to treat resistant partial epilepsy and generalised anxiety disorder.
