Nicotine patches are transdermal patches used to treat smoking or tobacco addiction as nicotine replacement therapy. They have been available since 1992 when the FDA approved four transdermal patches of nicotine, two of which have been sold without a prescription since 1996. The patch, in theory, should supplement the urge to smoke a cigar because, by focusing on the skin (usually on the arm, shoulder, or buttock), it releases a nicotine dose less than that of a cigarette, but releasing the endorphins that would be released with the dose of tobacco that would consume the person, removing the urge to smoke.
Regarding its efficacy, there is still no conclusive data but researchers have found that they are more effective than placebo and nicotine gum, and that the effect is greater if used with behavioral methods and nicotine antagonist drugs such as mecamylamine and naltrexone as well as the bupropion antidepressant. Nicotine patches should not be used during pregnancy because nicotine may help trigger newborn-related cognitive defects and fetal exposure to nicotine could be responsible.
