Gabapentin is primarily used to treat which condition?

Gabapentin is primarily used to treat partial seizures, which is a type of seizure that begins in a specific area of the brain and can cause a variety of symptoms, depending on the area affected. Gabapentin works by stabilizing electrical activity in the brain and is effective in reducing the frequency and severity of these seizure episodes.

This medication is also used for other conditions, such as neuropathic pain, but its main indication in the context of your question is for partial seizures. The drug has been widely researched and is approved by regulatory agencies specifically for this use, making it a cornerstone in the management of epilepsy, particularly in patients who experience focal seizures.

Other options mentioned, such as high cholesterol, insomnia, or gastroesophageal reflux disease, are not indications for gabapentin. Treatments for these conditions involve other classes of medications or lifestyle changes that are more appropriate to their specific pathology.
