Intended Use: For the treatment of partial onset seizures and neuropathic pain (pain from nerve damage) associated with diabetes and shingles.
Profile of User: An individual with any of the above conditions. The drug is also being used off-label by people with multiple sclerosis who suffer from neuropathic pain as well as by people with fibromyalgia and general anxiety disorder.
What It Is: A structural derivative of the neurotransmitter GABA (though it does not bind to GABA receptors).
How It Works: Although the mechanism of action is unknown, the drug is thought to modulate voltage-gated calcium channels in the central nervous system. Pregabalin binds to alpha2-delta sites, which are auxiliary subunits of voltage-gated calcium channels. Prolonged use of pregabalin increases the rate of GABA transport.
History: • Lyrica is a successor drug to Neurontin (gabapentin), another anti-seizure drug that was put on the market by Pfizer in 1983. What seems to be the main difference between the two is that Lyrica is more potent and has fewer side effects. • Following six double-blind placebo-controlled trials, the FDA approves Lyrica on December 31, 2004 for the treatment of neuropathic pain associated with diabetes and shingles. • Following three double-blind placebo-controlled trials, the FDA approves Lyrica on June 10, 2005 for the treatment of partial onset seizures. • September 19, 2005 Canada approves Lyrica for the treatment of neuropathic pain associated with diabetes and shingles. According to my pharmacist, he also currently dispenses it for seizures, depression, and neuropathic pain associated with MS. Because I got a free sample from the MS clinic, I wonder if Pfizer is seeking approval for the use of Lyrica for MS neuropathic pain.
Benefits: Reduction of seizures by 51% and a significant (though subjective) reduction of neuropathic pain.
Administration: Lyrica is taken orally up to three times a day with a maximum of 600 mg per day.
Cost: Lyrica costs approximately $111 a month in Canada. Pharmacare does not cover it and private coverage varies. For my month supply that I just bought, I paid $28.00 and my private insurance, Green Shield, paid the rest.
