July 14, 2005 - Purdue Pharma has voluntarily taken its pain-relieving
Palladone capsules off the market, the drugmaker says in a news release.
The company took the action on July 13 following an FDA request to withdraw
Palladone because of safety concerns.
The FDA approved Palladone in September 2004. The drug was launched by
Purdue Pharma this February.
Palladone was approved for the management of persistent, moderate-to-severe
pain in patients requiring continuous, around-the-clock pain relief with a
high-potency opioid for an extended period of time, states a Purdue Pharma news
Patients taking Palladone should consult their doctors about alternative
treatments, states an FDA news release.FDA's Statement
An FDA news release states that "serious and potentially fatal adverse
reactions can occur when Palladone (hydromorphone hydrochloride) extended
release capsules are taken together with alcohol."
Hydromorphone is a narcotic analgesic; it relieves pain and is also a cough
According to the FDA news release, "Palladone is a once-a-day pain
management drug containing a very potent narcotic. New data gathered from a
company-sponsored study testing the potential effects of alcohol use shows that
when Palladone is taken with alcohol the extended release mechanism is harmed
which can lead to dose-dumping."
Dose-dumping, the FDA says, is the rapid release of the drug's active
ingredient into the bloodstream. The agency's news release says dose-dumping,
even with a low dose of Palladone (12 milligrams), could lead to "serious,
or even fatal, adverse events in some patients."
The FDA warns that the risk increases for higher doses of Palladone.
Symptoms of a hydromorphone overdose include slow breathing, seizures,
dizziness, weakness, loss of consciousness, confusion, coma, tiredness, cold
and clammy hands, and small pupils.
The FDA says Purdue Pharma has greed to suspend the sale of Palladone in the
U.S. until the company discusses safety issues with the agency.
"All powerful pain management drugs have serious risks if used
incorrectly, but the current formulation [extended release capsules] of
Palladone presents an unacceptably high level of patient risk," says Steven
Galson, MD, MPH, FDA acting director of the Center for Drug Evaluation and
Research, in the news release.
