This one has potential, unlike Pfizer’s inhaled-insulin dog Exubera:

The U.S. Food and Drug Administration said on Thursday it approved Pfizer’s Chantix tablet to help cigarette smokers stop smoking.

The active ingredient in Chantix, varenicline tartrate, acts at sites in the brain affected by nicotine, the FDA said.

The drug may help smokers trying to kick the habit by providing some nicotine effects to ease the withdrawal symptoms, and by blocking the effects of nicotine from cigarettes if they resume smoking, the agency said.

Data shows that the quit rate with varenicline was 23 percent through 52 weeks, versus 9 percent with placebo.
