A Massive List of Other Drugs in the Same Class as Gabapentin

Looking for other drugs in the same class as Gabapentin? We’ve compiled a large list of Gabapentin alternatives.

Gabapentin is classified as an anticonvulsant. It’s used for pain management, epilepsy, restless leg syndrome and hot flashes. In general, anticonvulsants “work” by increasing the inhibitory activity of the neurotransmitter GABA, or decrease the activity of the excitatory neurotransmitter glutamate.

Gabapentin is a GABA analogue – it’s chemical structure is a modified version of the neurotransmitter GABA. This means that Gabapentin behaves similarly to GABA in the brain. Gabapentin tends to decrease anxiety, pain perception and promote a relaxed mental state.

What Other Drugs Are in the Same Class as Gabapentin?

The follow table is a list of Gabapentin alternatives – all of which are anticonvulsants. Most of them are approved for epilepsy, but are used off-label for other purposes. For example, valproic acid is used both for epilepsy but also as a mood stabilizer.
