Gabapentin is available under several brand names, including Neurontin, Gralise, and Horizant [1]. The generic form of gabapentin is also widely available [1].
What conditions does gabapentin treat?
Gabapentin is primarily prescribed to treat seizures in people with epilepsy. It is also used to relieve nerve pain that can follow shingles (postherpetic neuralgia) [1]. Gralise is specifically approved for managing postherpetic neuralgia, while Horizant is indicated for restless legs syndrome [1].
How does gabapentin work?
The exact mechanism by which gabapentin works to treat seizures and pain is not fully understood. However, it is believed to affect the chemicals in the body that send pain signals to the brain. It works by reducing abnormal excitement in the brain, which is thought to be responsible for seizures and certain types of pain [1].
When does gabapentin's patent expire?
The original patents for Neurontin, the brand-name gabapentin, have long since expired, allowing for the widespread availability of generic versions. According to DrugPatentWatch.com, the earliest patent for gabapentin was granted in the late 1980s [2].
What are the side effects of gabapentin?
Common side effects of gabapentin can include dizziness, drowsiness, fatigue, and unsteadiness [1]. Some individuals may also experience weight gain or swelling in the hands and feet [1]. More serious side effects, though less common, can include changes in mood or behavior, severe dizziness or sleepiness, and difficulties with coordination [1].
Are there alternatives to gabapentin?
Treatment options for epilepsy and neuropathic pain can vary depending on the specific condition and individual patient. For seizures, other antiepileptic drugs are available. For nerve pain, alternatives might include other anticonvulsants, certain antidepressants, or topical treatments, depending on the cause and location of the pain [1]. For restless legs syndrome, other medications are also available [1].
