A pill to help you quit smoking
Global pharmaceutical firm Pfizer has developed a pill that they claim can help you quit smoking.
The wonder pill ‘Chantix’, which has already been approved by a drug licensing body in US, is being considered by European regulators too and could be on sale in Britain soon, reported the online edition of Daily Mail.
The trials of Chantix, also known as varenicline tartrate, suggest it is more effective than Zyban, the current anti-smoking drug, it said.
Researchers randomly assigned 626 people to either Chantix at three different doses, to Zyban, or to a placebo. The participants, who were aged between 18 and 65, used their assigned study drug for a week before quitting cigarettes completely.
They took the pills for about seven weeks, then were followed for a year. At the end of four weeks, 48 percent of participants who took Chantix twice daily successfully broke their habit compared with 33 percent on Zyban and 17 percent of people given a dummy drug.
At the end of 12 weeks, the confirmed continuous quit rates were 38.8 percent for the highest dose of varenicline, 19.8 percent for zyban, and 10.6 percent for a placebo.
Craving was significantly reduced at all weekly time points for those taking the highest dose of varenicline compared with a placebo. Zyban also reduced craving, but to a lesser extent.
Researcher Mitchell Nides said: “In this study Chantix taken twice daily effectively helped subjects quit smoking, with a response rate three times higher than those for a placebo.”
The research showed the pill had some side effects, including nausea, but spacing out the doses
