Pregabalin is structurally similar to gamma-aminobutyric acid (GABA) - an inhibitory neurotransmitter. It may be used to manage neuropathic pain, postherpetic neuralgia, and fibromyalgia among other conditions. Although as per the FDA Label the mechanism of action has not been definitively defined, there is evidence that pregabalin exerts its effects by binding to the α2δ subunit of voltage-dependent calcium channels. Pregabalin is marketed by Pfizer under the trade name Lyrica and Lyrica Cr (extended release). It may have dependence liability if misused but the risk appears to be highest in patients with current or past substance use disorders.
Pregabalin is indicated for the management of neuropathic pain associated with diabetic peripheral neuropathy, postherpetic neuralgia, fibromyalgia, neuropathic pain associated with spinal cord injury, and as adjunctive therapy for the treatment of partial-onset seizures in patients 1 month of age and older.
