Metformin, the most widely used medication for diabetes, has also been shown to help treat dementia and some cancers. New research shows smoking cessation may be added to that list. The research team found that after giving mice metformin the animals displayed reduced symptoms when going through nicotine withdrawal. Metformin, the most widely used medication for diabetes, has also been shown to help treat dementia and some cancers. New research from the Perelman School of Medicine at the University of Pennsylvania and Johns Hopkins Medicine shows smoking cessation may be added to that list. the research team found that after giving mice metformin the animals displayed reduced symptoms when going through nicotine withdrawal. "Although we are just beginning to characterize this new role for metformin, our study suggests that the protein it acts on could be a new target for smoking cessation treatment," said senior author Julie Blendy, Ph D, a professor of Systems Pharmacology and Translational Therapeutics at Penn. , investigators say metformin, an inexpensive drug commonly used to treat patients with type 2 diabetes, appears to block symptoms of nicotine withdrawal in rodents. D., of the Johns Hopkins University School of Medicine's Division of Endocrinology, Diabetes and Metabolism, along with researchers at the University of Pennsylvania, found that laboratory mice that had been exposed to a two-week regimen of nicotine displayed no withdrawal symptoms when given the diabetes drug metformin. Food and Drug Administration to help people break their addiction to nicotine, but smoking cessation rates remain low -- at about 15 percent -- even though some studies say up to 70 percent of smokers want to quit. Cigarette smoking is the leading cause of preventable illness and death in the United States, implicated in more than 500,000 deaths each year, according to public health officials. Therapies now available are nicotine replacement, an antidepressant and a medication aimed at reducing the cravings for and pleasurable effects of cigarettes, none of which directly treats nicotine withdrawal symptoms, according to Kim. Based on previous studies that identified how nicotine affects brain chemistry, Kim and his colleagues hypothesized that metformin might eliminate anxiety, irritability and other withdrawal symptoms. For the new study, the research team focused on activating an enzyme known as AMP-activated protein kinase, or AMPK, which -- among other roles -- stimulates the breakdown of glucose for energy. Kim and his colleagues discovered that the AMPK pathway is activated in mammals following chronic nicotine use, but is repressed during nicotine withdrawal. They set out to find whether AMPK, stimulated by metformin, could lessen or even eliminate the symptoms of nicotine withdrawal. "This is the first-ever study to examine AMPK's relation to nicotine dependence," says Kim.
"Type 2 diabetes drug could be used to treat nicotine withdrawal for people trying to quit smoking," reports the Mail Online. This follows a study, carried out in mice, that explored whether the diabetes drug metformin could ease nicotine withdrawal symptoms. Prior research has shown nicotine activates a particular chemical pathway (AMP-activated protein kinase, or AMPK) in an area of the brain that controls memory and emotions. Cutting out nicotine stops the activation of this enzyme, and this is thought to contribute to the nicotine withdrawal symptoms – such as anxiety, irritability and loss of concentration – most smokers experience when trying to quit. As metformin has been shown to activate AMPK, the researchers wondered if this could compensate for the sudden withdrawal of nicotine. They found that when mice exposed to nicotine were injected with metformin before nicotine withdrawal, it reduced their anxiety, as measured by the amount they ate and the number of marbles they buried. However, humans are not mice, and these early findings can't be applied to us. .pass_color_to_child_links a.u-margin-left--xs.u-margin-right--sm.u-padding-left--xs.u-padding-right--xs.u-relative.u-absolute.u-absolute--center.u-width--100.u-flex-inline.u-flex-align-self--center.u-flex-justify--between.u-serif-font-main--regular.js-wf-loaded .u-serif-font-main--regular.amp-page .u-serif-font-main--regular.u-border-radius--ellipse.u-hover-bg--black-transparent.u-hover-bg--black-transparent:hover.
