Gabapentin is a prescription medication widely used for the treatment of nerve-related pain and certain seizure disorders. It belongs to the anticonvulsant class of drugs but is often prescribed for conditions beyond seizures, due to its ability to calm overactive nerve signaling in the nervous system. Gabapentin works by modulating calcium channels in nerve cells, reducing excessive electrical activity that can cause pain or seizures. This mechanism makes it particularly effective for neuropathic pain, which is pain caused by nerve damage, and for preventing certain types of seizures.
