The U.S. Food and Drug Administration issued an alert today on the safe and correct use of Tussionex Pennkinetic Extended-Release Suspension in response to numerous reports of adverse events--including death--associated with the misuse and inappropriate use of this potent cough medication.

Tussionex is a prescription cough medicine containing hydrocodone, a narcotic ingredient, and the antihistamine chlorpheniramine. The product is approved for use in adults and children over the age of six years old, and should be given no more frequently than every 12 hours (“extended-release”).

“There is a real and serious risk for overdosing if this medication is not used according to the labeling,” said Curtis Rosebraugh, M.D., M.P.H., acting director of the FDA's Office of Drug Evaluation II. “Today’s action is an example of the FDA working with drug manufacturers throughout a product’s lifecycle to keep health care professionals and patients informed of new safety data.”

Adverse event reports associated with Tussionex have included life-threatening side effects and deaths in patients, including children. These reports reveal physicians and other health professionals are sometimes prescribing, and patients are sometimes taking, more than the recommended dose or taking the medication more frequently than every 12 hours. The reports also show that Tussionex is sometimes prescribed or given to children less than 6 years old, for whom this medication is not approved.

Highlights of the FDA’s recommendations to health care professionals include:

Tussionex should not be used (is contraindicated) in patients less than 6 years old. FDA has received reports of death in children less than 6 years of age who have been prescribed Tussionex.

Consult the prescribing information to determine the correct dose and dosing frequency of Tussionex. Tussionex is an extended-release formulation that should not be prescribed at an interval less than 12 hours.

Discuss with the patient the amount of and frequency of Tussionex to be given. Instruct patients not to take, and parents not to administer Tussionex more frequently than every 12 hours.
Highlights of the FDA’s recommendations to patients include:

One of the two ingredients in this long-acting cough product is hydrocodone, a narcotic. Too much hydrocodone can cause life-threatening breathing problems and death. Call your doctor right away if you have taken this medicine and have trouble breathing, slow heartbeat, severe sleepiness or cold, clammy skin.

For Tussionex, use a medicine syringe or other device designed to measure liquid medications. A household teaspoon or tablespoon should not be used because the spoons vary in size and you may receive too much or too little of the medicine. Ask your doctor or pharmacist if you are unsure how to measure the medicine.

If the cough is not controlled despite taking the prescribed dose at the recommended interval, talk to your doctor.
The manufacturer of Tussionex Pennkinetic Extended-Release Suspension (UCB Inc, Smyrna, Ga.) has agreed to update the labeling, including information that Tussionex should not be prescribed to or used in children less than 6 years of age, as well as the need for accurate dosing.

This alert does not impact short-acting cough products containing hydrocodone that can be given every 4 to 6 hours. However, the FDA is reviewing safety information on these other hydrocodone containing cough products and will provide updates as new information becomes available.

The lives of 22,000 patients could have been saved if U.S. regulators had been quicker to remove a Bayer AG drug used to stem bleeding during open heart surgery, according to a medical researcher interviewed by CBS Television's 60 Minutes program.

The drug Trasylol was withdrawn in November at the request of the FDA after an observational study linked the medicine to kidney failure requiring dialysis and increased death of those patients.

It had been given to as many as a third of all heart bypass patients in the United States at the height of its use over a period of many years, according to the report.

Dr. Dennis Mangano, the study's researcher, said during the program that 22,000 lives could have been saved if Trasylol had been taken off the market when he first published his study in January 2006, according to a CBS News report on its Web site ahead of a broadcast slated for next Sunday.

He said in the broadcast that Bayer failed to disclose to the FDA during an FDA advisory panel meeting in September 2006 -- at which Mangano's negative findings were discussed -- that the German drugmaker had conducted its own research which confirmed the same dangers established by his study.

The chairman of the FDA advisory panel, Dr. William Hiatt, told 60 Minutes he would have voted to remove Trasylol from the market had he been informed about Bayer's study, according to the CBS report.

Bayer spokeswoman Meredith Fischer said she could not comment about the broadcast until it is aired, including allegations that the drugmaker had failed to protect patients.

She said Bayer is facing a number of product-liability lawsuits filed by patients who had taken the medicine or their families, but said she not know how many lawsuits were filed.

The New England Journal of Medicine reports about the recent drug Trasylol.

September 30 is becoming a day of infamy for drug safety. On that date in 2004, Merck announced that rofecoxib (Vioxx) doubled the risk of myocardial infarction and stroke, and the company withdrew the drug from the market after 5 years of use in more than 20 million patients. On September 30, 2006, a front-page article in the New York Times reported that the Food and Drug Administration (FDA) had issued a warning that the antifibrinolytic drug aprotinin, widely used to reduce perioperative bleeding in patients undergoing cardiac surgery, could cause renal failure, congestive heart failure, stroke, and death.

Some experts had been concerned about aprotinin (Trasylol) ever since its approval in 1993.1 As Hiatt explains in his Perspective article in this issue of the Journal (pages 2171–2173), one of two epidemiologic studies reported early this year provided support for this concern. In an observational study involving 4374 patients who underwent coronary revascularization,2 Mangano et al. found that patients who were given aprotinin had an incidence of postoperative renal failure requiring dialysis that was more than twice that among patients who received different agents. Among patients undergoing uncomplicated coronary-artery surgery, those given aprotinin had a 55% increase in the incidence of myocardial infarction or heart failure and a 181% increase in the incidence of stroke or encephalopathy. The authors advised against further use of the drug, since safer, cheaper alternatives are available.

After the study was published, the FDA moved to convene an advisory committee to reassess the drug's safety and assembled the relevant data. The committee met on September 21, reviewed the available evidence, and concluded that there was no need for additional warnings on the drug's official labeling.

What put aprotinin on the front page on September 30, however, was the revelation that its manufacturer, Bayer, had hired a private contract research organization to perform its own large observational study of postoperative complications in patients given the drug. The analysis, completed in time for the FDA meeting, reached conclusions similar to those of Mangano et al. It, too, adjusted for a wide variety of clinical characteristics and showed that patients who received aprotinin had higher mortality rates and substantially more renal damage than those given other treatments. But neither Bayer nor its contractor had provided the report to the FDA or even acknowledged its existence before the meeting.

The U.S. Food and Drug Administration (FDA) today approved revised labeling for Trasylol (aprotinin injection) to strengthen its safety warnings and to limit its approved usage to specific situations. Trasylol is given to patients before heart surgery to reduce bleeding and the need for blood transfusions. Trasylol is marketed by Bayer Pharmaceuticals Corporation, Leverkusen, Germany.

"The purpose of the label change is to inform physicians and patients about the risks associated with Trasylol and to ensure they understand the new warnings and use the product as directed by the label," said Steven Galson, M.D., MPH, Director of FDA's Center for Drug Evaluation and Research.

The new labeling specifies that Trasylol should only be given to patients who are at an increased risk for blood loss and blood transfusion in the setting of coronary bypass graft surgery (a procedure used to improve blood flow to the heart) when patients undergo cardiopulmonary bypass (a procedure that allows a machine to take over the heart's functions when it is stopped during surgery). The changes also include a warning that Trasylol increases the possible risk for kidney damage, and suggest ways to manage and reduce the patient's risk for hypersensitivity (exaggerated immune) reactions.

The labeling changes follow an FDA-conducted review of safety information that FDA became aware of after the product was introduced to the market. FDA began this safety review of Trasylol in January 2006. The review was triggered by the results of two published research studies. One study reported an increase in the possibility of kidney failure, heart attack and stroke in patients treated with Trasylol compared to those treated with other drugs. The other study reported an increase in the possibility of kidney damage compared to other drugs, but did not show an increased risk of heart attack or stroke. On February 8, 2006, FDA issued a Public Health Advisory regarding these new findings with Trasylol. On September 21, 2006, FDA held a public meeting of the Cardiovascular and Renal Drugs Advisory Committee to discuss the safety and overall risk-benefit profile for Trasylol. At that meeting, the committee discussed the findings from the two published observational studies, a Bayer worldwide safety review, and the FDA review of its own post-marketing database, and made recommendations for labeling changes. The labeling changes for Trasylol are based upon the recommendations of that advisory committee.

FDA announced on September 29, 2006, that Bayer informed the agency of an additional safety study on September 27, 2006. The preliminary results from that study suggest that in addition to serous kidney damage, Trasylol may increase the chance for death, congestive heart failure (a weakening of the heart), and strokes. The FDA review of this additional Trasylol safety information is continuing and it may result in other actions, including additional changes to the labeling.
