How long has gabapentin been on the market?

How long has gabapentin been available to patients?

Gabapentin has been on the market since the early 1990s. The drug was first approved by the U.S. Food and Drug Administration in 1993, which places its market availability at roughly 30+ years as of today.

Does the timeline refer to the first approval or generic entry?

Most “on the market” timelines refer to the first regulatory approval (not when generics launched). For gabapentin, that means the original FDA approval in 1993, followed by later generic availability as exclusivity and patents expired (which is why many people first experience gabapentin as a generic rather than under the original brand).

Where can I verify key dates (approval, exclusivity, patents)?
