FDA Grants Ivax Final Approval for Generic Neurontin

The FDA recently granted Ivax final approval for gabapentin tablets in 600- and 800-mg dosage strengths.

Gabapentin is the generic version of Pfizer's seizure medication, Neurontin.

U.S. sales for Neurontin in 600- and 800-mg tablets were $1.1 billion in 2004, according to IMS Health data. Ivax is presently litigating whether its gabapentin products infringe a patent held by Pfizer. A trial in the U.S. District Court of New Jersey has not yet been scheduled.
