Pregabalin, marketed under the brand name Lyrica among others, is a medication used to treat epilepsy, neuropathic pain, fibromyalgia, generalized anxiety disorder, diabetic nerve pain, pain after shingles, spinal cord injury nerve pain, and partial onset seizures in adults (an add-on treatment) with epilepsy.

Generic legal battle[edit | edit source]

  • Mar 2012, Pfizer blocked Israel-based Teva Pharmaceutical Industries and other manufacturers from selling generic versions of Lyrica.[3]
  • July 2012, the U.S. Food and Drug Administration (FDA) approved a generic version of Lyrica. Pregabalin, the active ingredient, is the generic name.[4][5] Two weeks after being approved by the FDA, marketing was blocked.[6]
  • 2014, Pfizer Inc., the maker of Lyrica, successfully blocked the marketing of Pregabalin generics until December of 2018 arguing that the generics should not be marketed and made available until their patent ran out.[7] Warner-Lamber, (a subsidieary of Pfizer), "still holds a “second medical use” patent for the use of pregabalin in the treatment of peripheral and central neuropathic pain, which expires in July 2017. A second medical use patent is one that relates to a new medical use for a known compound."[8][9]
  • Nov 2018, Pfizer Receives Six Months Pediatric Exclusivity For Lyrica® (Pregabalin)[10]
Pfizer Inc. (NYSE: PFE) today announced that the U.S. Food and Drug Administration (FDA) has granted pediatric exclusivity for LYRICA®. This grant extends the period of U.S. market exclusivity for LYRICA by an additional six months, to June 30, 2019.[10]
  • July 22, 1019, FDA approves first generics of Lyrica[11]
On July 19, the U.S. Food and Drug Administration approved multiple applications for first generics of Lyrica (pregabalin) for the management of neuropathic pain associated with diabetic peripheral neuropathy, for the management of postherpetic neuralgia, as an adjunctive therapy for the treatment of partial onset seizures in patients 17 years of age and older, for the management of fibromyalgia, and for the management of neuropathic pain associated with spinal cord injury.[11]
