Chantix significantly increases cardiovascular risks, according to another new study

Last month, the Food and Drug Administration warned of newly discovered cardiovascular risks associated with Pfizer’s popular smoking-cessation drug Chantix. But it turns out those risks, which include higher occurrence of heart attack and other adverse cardiovascular events in Chantix users with heart disease, pale in comparison to the findings of a larger study that found many of the same risks exist in Chantix patients with no heart disease.

Pfizer might fund study of Chantix and reduced risk of heart attack

CNN reports that Pfizer is thinking about launching a clinical test to determine if Chantix can help prevent smokers from having heart attacks.

Pfizer and other drug companies fund medical courses

The Milwaukee Journal Sentinel recently published a comprehensive report that exposes a very questionable relationship between the University of Wisconsin-Madison college of medicine and the drug industry. Using the University of Wisconsin-Madison as an example, the report describes how pharmaceutical companies have infiltrated the nation’s universities by funding physician education courses.

Will those long Chantix commercials disappear again?

In September, we learned that those long Chantix ads featuring the tortoise and the hare were reappearing on TV after Pfizer yanked them from the airwaves for several months. The drug maker pulled the ads when it became evident that a link existed between Chantix, , and suicide. Unfortunately, the new ads were even longer than the original by 30 seconds — for a total of 90 seconds — to accommodate all the new warnings.
