The new study, published in the Canadian Medical Association Journal, included the results of 14 random, blinded clinical trials that monitored cardiovascular health in more than 8,000 patients taking either Chantix or a placebo. Collectively, the trials found that 52 smokers in the Chantix groups suffered a heart attack, stroke, or other serious cardiovascular event while just 27 smokers taking placebo experienced the same cardiovascular problems. According to the New York Times, the “weighted, relative difference” between the two groups was 72 percent.

In the real world, the findings of these two latest Chantix studies mean that “doctors could expect to get one extra cardiac event associated with Chantix for every 28 smokers they treated with the drug,” the New York Times reported.

“We have known for many years that Chantix is one of the most harmful prescription drugs on the U.S. market, based on the number of serious adverse effects reported to the F.D.A.,” said Dr. Curt D. Furberg, a Wake Forest professor of medicine and senior author of the new report. “It causes loss of consciousness, visual disturbances, suicides, violence, depression and worsening of diabetes. To this list we now can add serious cardiovascular events.”

Dr. Furberg said that there were safer ways for smokers to quit and called for Chantix to be removed from the market.

“It piles up,” Dr. Furberg told the New York Times. “I don’t see how the F.D.A. can leave Chantix on the market.”

The study’s lead author, Dr. Sonal Singh, an assistant professor of medicine at Johns Hopkins University, said that since Chantix gained market approval in 2006, both Pfizer and the FDA have ignored signs that it might be linked to increased cardiovascular risks.

“The F.D.A. should have already put it on their warning label,” Dr. Singh said. “The risk is substantial, the risk is present in smokers without heart disease, and Pfizer knew about this for five years.”

“This would have raised a red flag for us if the flag hadn’t already been flying,” Dr. Celia Winchell, a leader in the FDA’s Center for Drug Evaluation and Research told the New York Times. However, short of a recall, the new findings are likely to have little impact on the FDA’s treatment of Chanitx because the drug already carries the agency’s strongest black-box warnings.

Since its debut, Chantix has been prescribed to 13 million people. Last year, the drug earned Pfizer $775 million in sales.

The FDA said that a randomized, double-blind, placebo-controlled clinical trial of 700 smokers were given Chantix or a placebo. All of the participating smokers had been previously diagnosed with heart disease. Although results found the risks to be relatively small, after 12 weeks more than twice as many Chantix patients suffered heart-related problems than the placebo patients. Seven out of 353 Chantix patients had a nonfatal heart attack, versus 3 out of 350 of the placebo patients.

Other adverse events reported to be more frequent in the Chantix group included angina pectoris, nonfatal myocardial infarction, need for coronary revascularization, and new diagnosis of peripheral vascular disease or admission for a procedure for the treatment of peripheral vascular disease.

The FDA advises that patients taking Chantix should check with their doctor if they have new or worsening symptoms of heart disease, such as difficulty breathing, chest pain or pain while walking.

Shortly after Chantix first became available in the U.S. in 2006, patients began reporting negative side effects to the FDA, most notably for suicidal thoughts and actions. In 2009, the FDA required Chantix to carry a black box warning, the agency’s strongest warning, because of persistent complaints about depression, violent mood swings, vivid dreams and nightmares, and suicidal behaviors.

WhyQuit reports that in surveys and scientific studies, more people were found to have successfully quit smoking long term using the cold turkey method than nicotine replacement therapies (NRT). NRT delivers smokeless nicotine to the user through chewing gum, lozenges, patches, and nasal sprays. NRT manufacturers typically tout their products as effective ways to ease nicotine withdrawal symptoms, which, in theory at least, should help smokers to quit. However, the vast majority of NRT users either resume smoking or become as addicted to expensive nicotine gum, patches, and lozenges.

Although no studies have compared cold turkey to Chantix, researchers have studied Chantix against NRT. While one study showed that Chantix appeared to be more effective than NicoDerm CQ in the short term, after a year, the success rate was statistically the same for both Chantix and NRT users. According to WhyQuit, the study forced Pfizer researchers to report that there were “no significant differences” between Chantix and NRT, but Pfizer’s ads do not mention the statistic.

If cold turkey is more effective than Chantix, and NRT is about the same, “why assume Chantix’s long list of serious use risks in exchange for little or no benefit?” WhyQuit asks.

The organization says that without support, “Chantix is probably worthless.” While counseling and support have proven their ability to drastically boost the chances of quitting permanently, Chantix has never been tested as a stand-alone smoking cessation aid. The drug is packaged with a support plan that includes a toll-free number and a web site to which consumers may turn for extra support. Pfizer hasn’t said what percent of Chantix users take advantage of the support program, but if the support seekers were subtracted from the total number of successful Chantix quitters, then the success rate would likely plummet.

Also, if Chantix were as helpful as Pfizer claims, then smoking rate in America ought to be descending. Since Chantix first appeared on the market, however, the adult smoking rate actually increased by one percent.

A third point of contention WhyQuit makes concerns the placebo studies that researchers conducted to gauge the effectiveness of Chantix. “Use of placebo controls in drug addiction studies is license to steal,” WhyQuit says, asserting that test subjects who experience severe withdrawal symptoms certainly know that they’ve been given a placebo rather than a drug that is supposed to mitigate those symptoms. Such studies allow Pfizer to exaggerate the efficacy of Chantix.

Fourthly, WhyQuit calls Pfizer out on its ads displaying people who claim, “I honestly love smoking,” saying that the ads mess with the drug-addicted brains of smokers. Pfizer adds appeal to Chantix by telling consumers that they may continue to smoke through the first week of treatment.

“It isn’t that we loved smoking but that we didn’t like what happened when we didn’t smoke,” WhyQuit claims.

“Drug addiction is about living a lie,” WhyQuit says. A dopamine reward pathway that convinces the addict that “nicotine use defines who they are, gives them their edge, helps them cope and that life without smoked nicotine would be horrible. Pfizer knows this and is now playing upon it.”

Finally, WhyQuit asserts that “what Pfizer will never teach smokers is that cold turkey accounts for far more long-term success stories each year than all other quitting methods combined.” After 3 days of nicotine abstinence, physical withdrawal symptoms dissipate and the brain works to heal its receptors. Counseling and support help cold turkey quitters with the emotional and psychological aspects of quitting smoking.

Such a finding would steer attention away from the host of negative side effects that Chantix is known to have. Moodiness, erratic or unpredictable behavior, depression, blackouts, memory loss, confusion, and suicidal thoughts and actions are some of the psychiatric side effects reported by many Chantix users. Non-psychiatric reactions such as sleeplessness and nausea are just as prevalent.

Soon after news of Chantix’s dark side emerged, the drug seemed to enter a tailspin. Pfizer yanked its commercials from the airwaves, numbers from the Institute of Safe Medicine Practices and the FDA revealed it to be one of the most dangerous drugs on the market, and sales and revenues plummeted.

Now that sales have steadied, the time is right for Pfizer to give its lackluster blockbuster a boost. According to CNN, “a study that demonstrates Chantix helps prevent heart attacks could mitigate the safety issues and revive sales, though there is the risk that a negative result would further damage sales.”

According to the CNN report, the study would examine whether Chantix reduces “the risk of subsequent heart attacks in smokers who have already had one.”

However, people who stop smoking, whether they use Chantix or some other smoking-cessation aid, will have already reduced their risk of heart attack simply by quitting smoking, so such studies would seem redundant.

But there you have it. If suicidal tendencies were considered a positive benefit of Chantix, you can bet Pfizer would be spending millions on finding more about that link.

According to the CNN report, Pfizer will decide whether to fund such a study by the end of the year.

For many people, however, (including me), the Chantix experience isn’t one of wild extremes. It’s more like a strange trip through life with a brain that feels somehow different from the brain you had before. You feel normal and behave normally most of the time, but occasionally you find yourself saying or doing something that is not you, and the realization that accompanies this uncharacteristic behavior leaves you feeling disembodied and maybe even a little crazy.

New York magazine recently published an excellent article by a guy who recounts his own journey through a landscape made murky by Chantix. If you are one of the people who are seriously considering taking Chantix but trepidatiously wonder what it will be like for you, read Derek De Koff’s story, which echoes the experiences of so many people in blogland.

De Koff writes, “After a few weeks on Chantix, I had managed to stop smoking altogether—but it didn’t feel like a triumphant turn of events. I’d become rather reclusive, avoiding calls from friends, and basically just shuttling back and forth between my office and my apartment. I began to dread six o’clock; it meant I had to walk through the streets again. The subway was now out of the question; it made me too nervous. I stopped going to the gym, too.

“I wondered whether Chantix was zapping my brain’s pleasure-delivery system to such a degree that not only did I find no reward in cigarettes, but I also found no reward in socializing, exercising, writing, or any of my usual self-stimulating tricks. I’d pace the floor, sit on the bed, channel surf, pace some more, try to read, but the room had a stale, sinking feeling.”

So many people have such enormous expectations of Chantix, but the basic truth is that it may work for you (at least in the short term) and it may not work for you at all. If you decide to use it, monitor your behavior closely. I’m one of the people who took Chantix unsuccessfully. Ultimately it was the power to control my own thoughts that worked for me, bolstered by the fact that I had spent hundreds of dollars on a drug that did nothing but make me feel weird, half crazy, and “out of it” most of the time.

Heralded by many doctors and other experts as the most promising smoking cessation aid yet developed, for the unique way in which it blocked nicotine from reaching key receptors in the brain, Chantix was set to take over the stop-smoking world. The prevailing attitude seemed to be “it’s high tech, therefore it’s better.”

But is Chantix better? A study comparing the effectiveness of Chantix to NicoDerm CQ reveals that in the short term, yes, Chantix is better. In the long term, however, the same study indicates there is no difference. The study randomly administered either 12 weeks of Chantix or 10 weeks of the NicoDerm patch to 746 participants and followed their progress for a year. Chantix showed a higher rate of success over NicoDerm during the last 4 weeks of treatment. After a year, however, the rates of success were statistically the same.

While browsing the web for the latest news about Chantix, I come across a lot of emails, blog posts, and reader comments written by people who are taking Chantix or are considering taking it. It occurred to me today that this blog could serve as a forum for discussing smoking cessation methods and comparing them to Chantix. As a former user of Chantix, I actually have more than the FDA-recommended 12-week experience with the drug, but that’s another story and I’ll save it for another post!

“Those in the VA who failed to properly notify America’s veterans that their medication could produce fatal side effects must resign their positions,” Lisicki said. “If not, then the VA secretary must take decisive action to terminate their employment.”

Lisicki issued the off-with-their-heads statement in response to reports (link) that the VA may have acted irresponsibly in its study of Chantix using veterans with Post Traumatic Stress Disorder (PTSD).

The VA originally said that 940 veterans with PTSD were enrolled in the study, but only 143 of them were receiving Chantix. (link) However, The Washington Times revealed the number of PTSD veterans receiving Chantix was actually 68 percent higher than the VA originally acknowledged: 241, as opposed to 143.

Of the 241 test subjects, there were 114 reported adverse effects, including 22 psychiatric events.

The VA also prescribed Chantix to some 32,000 other veterans. From that group, 27 were admitted to VA hospitals for apparent psychiatric disorders. Among those, 11 had attempted suicide, 9 had suicidal thoughts, six suffered from hallucinations, and 1 attempted homicide.

Last month, ABC News and The Washington Times revealed (link) the VA’s failure to notify the study’s veterans about the potential psychiatric hazards of Chantix until three months after the FDA’s initial warnings.

Secretary of Veterans Affairs James B. Peake, M.D. insists that the VA has nothing but the veterans’ best interests in mind in determining courses of treatment. After the joint ABC News / Washington Times broke, allegations emerged implying that big pharmaceutical companies and universities may be funding and compromising VA research and care. Dr. Peake called the allegations “ridiculous.”

Still, Dr. Peake has ordered four internal investigations of the Chantix study and the VA’s general operations, ostensibly to safeguard against repeating similar blunders in the future.

To Lisicki and many veterans, the VA’s neglect in informing PTSD veterans about the dangers of Chantix, followed by the administration’s unapologetic attitude, is inexcusable.

“Professional ethics and common sense just dictate that clinicians would stop their patients from taking the drug just to err on the side of safety for the veterans and their families,” Lisicki said.

If the VA tests Chantix on veterans with PTSD, then how would it be able to determine if the emotional and behavioral problems are caused by the drug or the psychological trauma? Wouldn’t being able to differentiate between two possible causes determine the best course of treatment?

Aren’t our veterans worthy of an administration that treats them with genuine care and, perhaps above all, compassion?

SOURCE: Chantix Recall › More veterans enrolled in Chantix study than originally revealed

Chantix is known to create or worsen several neuropsychiatric conditions including suicidal thought and actions.

All of the 940 veterans in the VA study had been diagnosed with Post Traumatic Stress Disorder (PTSD). 143 of those veterans were selected to receive Chantix. Those veterans were given the drug and $30 monthly payments.

The FDA published its first Chantix warning on Nov. 20, 2007, with subsequent warnings from the FDA and the manufacturer Pfizer. Three months passed, however, before the VA notified all relevant doctors and staff involved in the study, and even then, there was no mention of suicide.

James Peake, Veterans Affairs Secretary, said that the 940 veterans in the study would receive a personal warning letter from him. Another 31,000 additional veterans would receive the same warning, he told The Washington Times.

Peake also disclosed that 26 of the study’s PTSD veterans experienced adverse events, including three reports of contemplated suicide.

The drug’s propensity to ignite suicidal thoughts and actions, especially in patients with heightened emotional and mental volatility, was the central concern of those calling for an end to the VA study.

While the VA does not intend to stop the study prematurely, it has said that it will end the study if necessary. New subjects are not being enrolled in the study.

That snowball appears to be gaining speed and momentum. At least five congressman have queried the VA over the Chantix tests, and now a number of veteran’s groups are adding their voice to the chorus of anger.

The VA study proceeded without interruption even after FDA warnings surfaced announcing a strong link between Chantix, depression and suicide, and other adverse side effects. Since the story broke, the VA has been trying to brush aside concerns, claiming that it took reasonable action and notified all the appropriate people. However, based on all reports so far, the only people who weren’t notified were the veterans participating in the study.

Paul Rieckhoff, executive director of Iraq and Afghanistan Veterans of America, told ABC News that “it is
unacceptable for even one veteran to have been misled about the possible side effects of Chantix.”

The VA had previously dismissed claims that it acted irresponsibly, saying that the actions of one soldier weren’t enough to justify discontinuing a study that had potential value for many more veterans.

That one soldier is James Elliot, a US Army sniper with PTSD. Mr. Elliot had a run in with police a couple months after he began taking Chantix.

“Are you going to shoot me? Shoot me,” Mr. Elliot told cops when they found him in the street packing a loaded gun.

After hearing that the VA neglected to warn him about the risks of Chantix, Mr. Elliot claimed that he felt like a “Lab rat, guinea pig, disposable hero.”

“Our nation’s veterans are not guinea pigs,” said Paul Rieckhoff.

Paul Sullivan, executive director of Veterans for Common Sense (VCS), expressed his disappointment in the VA. “The VA should have done a better job protecting the human rights of our veterans,” he said.

“While VCS supports research to assist veterans, VA must bear a heavy burden of responsibility with these experiments on veterans diagnosed with PTSD,” said Sullivan, who wants the study to be suspended immediately.

Yesterday, Senators John Cornyn (R-TX) and Barack Obama (D-IL) rebuked the VA and demanded an investigation. Both the White House and VA officials dismissed the criticism, with White House deputy press secretary Tony Fratto calling the story an example of “irresponsible reporting.”

Today, however, more congressman are voicing their anger over the study, demanding answers, and calling for action.

Congressmen Bob Filner (D-CA), who is Chairman of the House Committee on Veteran Affairs, together with Rep. Ed Markey (D-MA), and Rep. Paul Hodes (D-NH) sent a letter to the Secretary of Veteran’s Affairs. In it, they voiced their alarm over the reported allegations and demanded copies of paperwork involved in the studies.

“Allowing, even encouraging, military veterans who have already made enormous sacrifices for our country to participate in drug studies that may cause serious, long-lasting health effects is tantamount to breaking our national promise to honor and support our veterans,” said Rep. Markey today.

The Congressmen sate in their letter, “When you’re taking advantage of a very vulnerable population, people who have served the country, and the agency that’s responsible for their welfare isn’t putting their welfare first, that’s a pretty serious breach of ethics.”
