Arthritis Drug Causes Recurrent Ulcers

December 27, 2002

The blockbuster arthritis drug Celebrex doesn't protect the stomach from dangerous bleeding ulcers as well as thought, a new study suggests.

Celebrex and two similar new anti-inflammatory drugs are heavily advertised as being safer for arthritis patients based on earlier research that found they caused fewer ulcers and other gastrointestinal complications than older anti-inflammatory medicines. Together, the three new drugs have annual sales exceeding $6 billion.

But their safety has been called into question recently. The new study, which focused on arthritis patients at high risk of recurrent ulcers, escalates the controversy involving Celebrex, showing nearly 10% each year would develop another bleeding ulcer.

  • The study found the same thing for an older anti-inflammatory drug combined with ulcer medicine Prilosec, which doctors often give arthritis patients to protect their stomachs.
  • In addition, neither treatment protected as many patients from dangerous kidney complications as past studies showed, the researchers said.
  • The Hong Kong researchers and some other experts said the results, while showing the treatments work the same, indicate more study is needed on preventing bleeding stomach ulcers in vulnerable older people who for years ease joint pain with nonsteroidal anti-inflammatory drugs, or NSAIDs.

"I think patients and doctors need to be aware ... there is a risk of gastrointestinal bleeding and there is a risk of renal toxicity," so high-risk patients should be monitored closely by their doctor, said Dr. John H. Klippel, medical director of the Arthritis Foundation.
