Gabapentin, sold under the brand name Neurontin among others, is an anticonvulsant medication used to treat partial seizures, neuropathic pain, hot flashes, and restless legs syndrome.[5][6] It is recommended as one of a number of first-line medications for the treatment of neuropathic pain caused by diabetic neuropathy, postherpetic neuralgia, and central neuropathic pain.[8] About 15% of people with diabetic neuropathy or postherpetic neuralgia have a measurable benefit.[9] Gabapentin is taken by mouth.[5]
Common side effects include sleepiness and dizziness.[5] Serious side effects include an increased risk of suicide, aggressive behavior, and drug reactions.[5] It is unclear if it is safe during pregnancy or breastfeeding.[10] Lower doses are recommended in those low kidney function.[5] Gabapentin is a gabapentinoid.[11] It has a molecular structure similar to that of the neurotransmitter γ-aminobutyric acid (GABA) and acts by inhibiting certain calcium channels.[12][11][13]
Gabapentin was first approved for use in 1993.[14][15] It has been available as a generic medication in the United States since 2004.[5] The wholesale price in the developing world as of 2015[update] was about US$10.80 per month;[16] in the United States, it was US$100 to US$200.[17] In 2017, it was the eleventh most commonly prescribed medication in the United States, with more than 46 million prescriptions.[18][19] During the 1990s, Parke-Davis, a subsidiary of Pfizer, began using a number of illegal techniques to encourage physicians in the United States to use gabapentin for unapproved uses.[20] They have paid out millions of dollars to settle lawsuits regarding these activities.[21]
