Objectives : The purpose of this study was to compare three therapies - auricular acupuncture, transdermal nicotine patch and therapy - in combination with auricular acupuncture and nicotine patch. Methods : The subjects of this study included 188 male smokers in their 20s, 30s, 40s and 50s, who visited Wonmi Public Health Center. They were evaluated with the Fagerstrom test for nicotine dependence, amounts of daily smoking and success rate of smoking cessation. The subjects decided on a therapy method strictly of their own choice. They were divided into three groups according to the therapy; auricular acupuncture group (62 persons), nicotine patch group (69 persons) and combination therapy group (57 persons). Results : All three groups resulted in statistically significant reducing effects of nicotine dependence and amounts of daily smoking. In the combination therapy group, nicotine dependence was significantly decreased by more than those of the other groups. There were no statistically significant differences in decrements of daily smoking and success rate of smoking cessation among the three groups. Conclusions : The above results suggest that auricular acupuncture and transdermal nicotine patch have significant effects of smoking cessation. If they are combined, it is expected that therapies for smoking cessation would be developed.

Nicotine transdermal therapeutic systems $(TTS_S)$ have been regarded as an effective mean to aid smoking cessation. However, most of nicotine $TTS_S$ in the market have some problems such as unpleasant side effects and skin irritation due to the excess amount of the drug permeated and the properties of the additives employed. In order to solve these problems, new nicotine $TTS_S$ were formulated using biocompatible additives. The optimized formula of the drug layer consisted of nicotine, propylene glycol and poloxamer 188 at the ratio of 1.2: 17.0: 2.0. The drug layer had the sickness of $1,250\;{\mu}m$, the pH of 8.12. The skin permeation rate of nicotine from optimized nicotine patch (NP) was $21.5\;{\mu}g/cm^2/h$. Transdermal administration of nicotine patch has been carried out for the determination of pharmacokinetic parameters in rats. Steady-state plasma concentration of nicotine following transdermal application of NP (area of patch = $15\;cm^2$) on the dorsal skin of rats was 143.2 ng/ml and AUC for 24 hrs was 3,022 ng h/ml. In case of $EXODUS^{\circledR}$ and Nicotinell $TTS^{\circledR}$, the steady-state plasma concentration of nicotine and ACU for 24 hrs were 428.9 ng/ml, $9,121\;ng{\cdot}hr/ml$ and 155.3 ng/ml, $3,152\;ng{\cdot}h/ml$, respectively. NP showed the experimental plasma nicotine concentration profile was very similar to the simulated one and had an appropriate skin permeation rate and a steady-state concentration of nicotine, which can show therapeutic blood levels of the drug for 24 hrs without severe side effects.

The pharmacokinetic properties of transdermal nicotine patches (TNPs) are different from those of other routes of nicotine administration; further, acute nicotine poisoning by TNPs may present with different clinical features. In the present report, we describe the case of a 23-year-old woman who was admitted to emergency department (ED) at Jeju National University Hospital with loss of consciousness. Five hours before the ED visit, she used multiple TNPs to attempt suicide. Initially, nausea and vomiting occurred, and the symptoms worsened over time. We immediately removed the TNPs, and the application sites were gently washed with sterile water. The patient's level of consciousness gradually improved, and she fully recovered an altered mental status 5 hours later. Her initial urinary cotinine level was 324 ng/mL. Physicians should be aware that acute nicotine poisoning by TNPs can cause various toxic symptoms.

The bioequivalence of two nicotine patches was evaluated in 16 normal male volunteers (age 21 ~ 27 yrs) following single transdermal application. Test product was "Nicostop patch" made by Sam Yang Co. and reference product was "Nicotinell TTS patch" made by Korean Searle Ciba-Geigy Co. After nicotine patches were applied onto the inside of the forearm, blood was taken at predetermined time intervals and the nicotine concentration in plasma was determined with a sensitive GC method using NPD detector. AUC and Cm\ulcorner were calculated and statistically analyzed for the bioequivalence of the two products. The results showed that the differences in AUC and $C_{msx}$between two products were 5.47% and 2.70%, respectively. The powers (1-$\beta$) for AUC and $C_{max}$. were >90% and 88.76%, respectively. Detectable differences($\Delta$) and confidence intervals were all less than 20%. All of these parameters met the criteria of KFDA for bioequivalence, indicating that "Nicostop patch" is bioequivalent to "Nicotinell TTS patch" . . .
