The brand name for gabapentin is Neurontin [1].
What is Neurontin prescribed for?
Neurontin is prescribed to treat seizure disorders, including partial seizures in adults and children. It is also used to manage postherpetic neuralgia, a type of nerve pain that can occur after shingles [1].
What other conditions is gabapentin used for off-label?
While Neurontin is FDA-approved for specific indications, gabapentin is frequently used off-label for various other conditions. These can include restless legs syndrome, anxiety disorders, hot flashes, and neuropathic pain beyond postherpetic neuralgia, such as diabetic neuropathy [2].
How does gabapentin work?
The exact mechanism by which gabapentin exerts its anti-seizure and analgesic effects is not fully understood [3]. However, it is known to bind to auxiliary subunits of voltage-gated calcium channels. This binding may modulate calcium currents in nerve terminals, leading to a decrease in the release of certain excitatory neurotransmitters in the central nervous system [3].
