Abstract
Pregabalin is an α2-δ ligand that binds to and modulates voltage-gated calcium channels, exerting its intended effect to reduce neuropathic pain. Pregabalin is the second of only two medications that are US FDA approved for the treatment of neuropathic pain associated with diabetic peripheral neuropathy; it is also the third medication for the treatment of postherpetic neuralgia. Currently, there are three pivotal clinical studies documenting the efficacy and safety of pregabalin for the treatment of painful diabetic neuropathy, and three clinical studies regarding the use of pregabalin for pain associated with postherpetic neuralgia. This article will review each of these studies, as well as provide a clinical review for the use of pregabalin in the treatment of neuropathic pain.
