Epilepsy Adjunctive therapy of focal seizures with and without secondary generalization. Recommendations summarized from NICE (2012) Seizure types—on referral to tertiary care (focal seizures), contraindicated (generalized tonic- clonic seizures, tonic/ atonic seizures, absence seizures, myoclonic seizures). Epilepsy types—on referral to tertiary care (benign epilepsy with centrotemporal spikes, panayiotopoulos syndrome, late- onset childhood occipital epilepsy), contraindicated (absence syndromes, idiopathic generalized epilepsy, juvenile myoclonic epilepsy, Dravet syndrome, Lennox– Gastaut syndrome). Psychiatry Generalized anxiety disorder. Neurology Peripheral and central neuropathic pain.
Pregabalin is an anticonvulsant drug used for neuropathic pain, as an adjunct therapy for partial seizures, and in generalized anxiety disorder. It was designed as a more potent successor to gabapentin. Pregabalin is marketed by Pfizer under the trade nam

Pregabalin (Lyrica), an analog of GABA that is related to gabapentin, has been extensively studied in the treatment of GAD, fibromyalgia, neuropathic pain, and partial complex seizures.It appears to act even more selectively on the a2-δ subunit of calcium channels found in brain than does gabapentin. Pregabalin received FDA approval in late 2004 for use in treating neuropathic pain and epilepsy. In 2008, it became the first drug approved for the treatment of fibromyalgia.Even though prcgabalin reccived approval for the treatment of GAD in the European Union in 2006, the FDA has not approvedpregabalin for GAD in the United States as of this writing.With the consistent efficacy in clinical trials and the known safety of pregabalin in clinical expericnce, it is not completely clear what has held up approval of prcgabalin for GAD.There was reported concern of the risk-benefit ratio for the drug,given the hepatotoxicity seen in micc, but this has not proven to be a problem postrelease in humans. Pregabalin is categorized as an anticonvulsant and analgesic. The drug is under re-review currently by the FDA. Pregabalin has a potential for abuse and misuse. Pregabalin is regulated as a Schedule V compound in the United States.
