MENLO PARK, Calif. — A drug maker is suing the Food and Drug Administration to force the agency to give a special designation to one of its drugs.
Depomed announced that it had filed suit against the FDA in federal district court for the District of Columbia seeking an order that would require the agency to grant the drug Gralise (gabapentin) orphan drug exclusivity for the management of post-herpetic neuralgia. The disease, also known as PHN, is a condition causing prolonged pain in people who have had shingles, a complication of chickenpox.
