Wonder drug for smokers?
Sofia Kosmetatos / The Detroit News
Jo Ann Ritch nursed a smoking habit for 45 years before quitting last
month. She kicked her two-pack-a-day addiction five days after she
started taking Chantix, Pfizer's new prescription medicine to help
smokers quit.
"I was totally amazed," Ritch, 61, of St. Clair Shores said
of the power of Chantix to cut her cigarette cravings.
She's since been spreading the word to her smoking friends and co-workers.
The "wonder drug," as Ritch calls it, offers new hope for
thousands of longtime smokers who have struggled to break free from
one of the strongest addictions known to medicine.
With more cities and counties banning smoking in public places, more
private businesses implementing smoke-free campuses, more employers
charging smokers extra for health insurance and with the price of
cigarettes climbing, the pressure is on for smokers to give up their
cigarettes.
And Chantix, which went on the market last summer after approval by
the Food and Drug Administration in May, appears to give many of them
more of a fighting chance to succeed.
Existing anti-smoking aides -- such as the nicotine patch and gum,
and even an antidepressant sold as Zyban -- have been helping smokers
quit for years, but research indicates Chantix works better.
The drug's early success among Metro Detroit smokers also suggests
it's a winner, local doctors and coordinators of stop-smoking programs
said. They say while Chantix won't work for everyone, it could be
the answer for many smokers, especially those who have tried to quit.
"We're very excited about having this medication," said
Dr. Ayman Soubani, a pulmonologist who practices at the Karmanos Cancer
Institute and DMC Harper University Hospital in Detroit.
"For the first time in a long time, (we have) a new medication
that is promising."
Pill among slew of options
For years, the only aids to help smokers quit were those that aimed
at replacing the nicotine in cigarettes, such as the patch, gum or
lozenges. Those options are widely available over the counter and
also come in prescription-only inhalers and nasal sprays.
In 1997, the FDA approved another type of aid -- the antidepressant
bupropion, already sold as Wellbutrin but rebranded as Zyban. It works
not only by replacing nicotine, but also by altering the brain's chemistry
in a way that helps some people stop smoking.
Then last year, the FDA approved varenicline, sold in the United States
under the brand name Chantix. It works by targeting specific receptors
in the brain that, when exposed to the nicotine in cigarette smoke,
trigger the brain's release of dopamine, a chemical that causes feelings
of pleasure. Those good feelings are one reason smokers have a tough
time quitting.
Chantix works in two ways: It blocks nicotine from stimulating these
receptors, so cigarettes don't deliver the same pleasure, and stimulates
the release of lower levels of dopamine to help decrease nicotine
cravings and withdrawal. It's usually taken for 12 weeks.
Study: Chantix more effective
With hardcore smokers, "just using any kind of product would
double your chances of quitting," said Linda Thomas, manager
of the University of Michigan Health System's Tobacco Consultation
Service.
But studies suggest that Chantix is more effective than going at it
alone or with Zyban. A study published in the Journal of the American
Medical Association in July showed that after 12 weeks of treatment,
44 percent of people taking Chantix quit, versus 29.5 percent of those
taking Zyban and 17.7 percent of those taking placebos.
"Those are awesome numbers," Thomas said.
A year later, 21.4 percent of participants who took Chantix were still
not smoking, compared to 16.1 percent for those who took Zyban and
8.4 percent for those who took a placebo.
Around town, smokers eager to quit are asking their doctors about
Chantix. And many are finding success.
"This is working for people who've tried all the other stuff,"
Thomas said.
Rosemary Marino, 47, a smoker since she was 13, had tried several
times to quit. She almost made it with the patch, but finally succeeded
on Chantix. The former one-pack-a-day smoker from Harper Woods has
been smoke-free since Feb. 12.
"I feel great," she said.
"If you do want to quit, this is the way to go."
Alex Reich, a paramedic from Waterford, smoked for 15 years and has
tried to quit numerous times using the patch, gum and Zyban. His insurance
didn't cover Chantix, but Reich didn't mind shelling out more than
$120 a month for it.
"I was paying $300 a month for cigarettes anyway," he said.
Unlike with previous attempts, Reich said he can't recall exactly
when he stopped smoking while using Chantix. "I just did,"
he said.
Drug comes with side effects
Chantix users are supposed to start taking the drug seven days before
they quit. The dose ramps up in the first week, and then again in
the second for the duration of the 12-week treatment.
The drug's most common side effect is nausea, which is why Delia Penny
of White Lake stopped taking it after a few days. "It wasn't
worth it to me," said Penny, 59. She gave Chantix a second shot,
but stopped taking it again after experiencing the same side effect.
Among the other possible side effects are increased appetite, a tired
feeling and headaches.
Doctors say the aids to help smokers quit vary, just as their reasons
for smoking. For people with oral fixations, gum may be the answer.
For others who like the feeling of cigarettes in their hands, an inhaler
might do the trick.
The cost of treatment also could play a role in what method smokers
try. Many insurance plans don't cover Chantix, though more are starting
to. Most insurers also don't cover over-the-counter smoking cessation
aides.
Blue Cross Blue Shield of Michigan, the state's largest insurer, covers
Chantix through its prescription plan. The Blue Cross HMO, Blue Care
Network, also covers Chantix, although to get the cheapest co-pay,
those customers must be enrolled in a smoking cessation program that
comes with phone support from nurses.
Support that helps smokers modify their behavior can increase success
rates, which is why Pfizer also offers its own network, called GETQUIT,
free of charge for people taking Chantix.
Chantix is no magic pill
Ultimately, for smokers to quit successfully, they have to really
want it, no matter what aid they choose, experts agree.
"If you don't have that motivation
nothing is going to
work," said Dorothy Molitor, coordinator of the smoking intervention
program at Henry Ford Health System.
"There is no magic pill," said Dr. Mark Richter, a family
physician in White Lake.
But, "this will be another tool -- a very strong tool -- that
we have in their hands when we talk to our patients and offer them
options to stop smoking," Soubani said.
