Varenicline is only the second nicotine free smoking cessation drug to gain Food and Drug Administration approval. Plans to market the twice daily tablet as Chantix. It s like with cancer or heart disease or high blood pressure or diabetes the more effective treatments you have, the better off patients are, said Dr. Varenicline works in two ways, by cutting the pleasure of smoking and reducing the withdrawal symptoms that lead smokers to light up again and again. Most other stop smoking drugs are various nicotine replacement therapies, sold by prescription and over the counter in gum, patch, lozenge, nasal spray or inhaler form. Several studies conducted in Europe on about, smokers and presented in November at an American Heart Association conference showed that a year after initial treatment with varenicline, abstinence rates were percent, versus percent among those given Zyban.

Just percent of those given dummy medicines had stopped after a year. The approved course of Chantix treatment is weeks, a period that can be doubled in patients who successfully quit to increase the likelihood they will remain smoke free, the FDA said.

Other clinical trials show the drug s effect is more pronounced in the short term percent of patients quit smoking following a week course of treatment with Chantix, compared to the percent of Zyban patients who quit, according to Pfizer. However, smoking cessation experts said the longer term data are more Clotrimazole topical cream, given the difficulty of quitting the habit for good.

It s not going to be a revolution, it s going to be a Shinco dvd player step forward, Thomas Glynn, director of cancer science and trends at the American Cancer Society, said of varenicline. Glynn added that the greatest value will be for smokers who have tried Zyban or nicotine replacement therapy but failed to quit. Varenicline latches on to the same receptors in the brain that nicotine binds to when inhaled in cigarette smoke, an action that leads to the release of dopamine in the pleasure centers of the brain. Taking the drug blocks any inhaled nicotine from reinforcing that effect.

Smoking kills nearly, Americans a year. Tobacco use, particularly cigarette smoking, is the single most preventable cause of death in the United States and is Celexa off weaning for a growing list of cancers, as well as chronic diseases including those of the lung and heart, said Dr. Fewer than one in smokers can do so without help, Schroeder said.

With help, whether it s a drug, counseling or both, the success rate rises at most to roughly one in five, he added. Both the FDA and European regulators recently shot down attempts by Sanofi Aventis to gain approval for Star radio in liberia, or Accomplia, as a stop smoking aid.

And at least two vaccines are being developed that could block nicotine from ever reaching the brain. Pfizer hopes to start selling the drug, for use by adults only, in the second half of the year.
