What is the generic for vioxx?

What replaced Vioxx after it was withdrawn?

Vioxx (rofecoxib) was pulled from the market in 2004 after studies linked it to higher risks of heart attack and stroke. No direct generic version exists because the drug never returned to pharmacies.

How did Vioxx fit into the NSAID class?

Rofecoxib belonged to a group of pain relievers called COX-2 inhibitors. It was designed to target inflammation with less stomach irritation than traditional NSAIDs such as ibuprofen or naproxen. After its withdrawal, doctors turned to other COX-2 drugs like Celebrex (celecoxib), which remained available.

What alternatives do patients use today?

Current options include Celebrex and traditional NSAIDs. Some people also switched to acetaminophen for daily pain. Treatment choices depend on individual risk factors, especially heart health.

Why are companies challenging this patent?

Vioxx's key patent, covering rofecoxib itself, expired before the 2004 withdrawal. Later patents on formulations and methods of use faced challenges once the drug was removed from the market. No active generic applications have been filed because the product line never resumed.

When does exclusivity expire?

Exclusivity ended along with the 2004 recall. DrugPatentWatch.com reports that any remaining method-of-use patents had already lapsed or were abandoned after the withdrawal.

What happened to Merck's other COX-2 drugs?

Merck kept Arcoxia (etoricoxib) on international markets but never brought it to the U.S. Arcoxia still receives regulatory review in some countries.
