This study examined the effect of gender and body weight on the pharmacokinetic properties of the Nicotine Transdermal System (NTS) (Nicoderm). This NTS was applied for 24 hours to 13 normal-sized men, 13 women, and 13 obese men, all of whom were smokers who had abstained from cigarettes for the previous 24 hours. Pharmacokinetic parameters were determined during a single application of the system. The mean nicotine maximal plasma concentration (Cmax) and area under the curve (AUC) values for women did not differ significantly from those for normal-sized men. Nicotine Cmax and AUC values, however, were significantly lower in obese compared with normal-sized men; nicotine AUC was strongly correlated to body weight and body mass index. Mean apparent nicotine elimination rate constant values were not significantly different between normal-sized and obese men, but the apparent elimination rate constant value was significantly higher in women. The possible clinical significance of the differences in nicotine AUC values with body weight is discussed.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D009538	Nicotine	Nicotine is highly toxic alkaloid. It is the prototypical agonist at nicotinic cholinergic receptors where it dramatically stimulates neurons and ultimately blocks synaptic transmission. Nicotine is also important medically because of its presence in tobacco smoke.	Nicotine Bitartrate,Nicotine Tartrate
D009765	Obesity	A status with BODY WEIGHT that is grossly above the recommended standards, usually due to accumulation of excess FATS in the body. The standards may vary with age, sex, genetic or cultural background. In the BODY MASS INDEX, a BMI greater than 30.0 kg/m2 is considered obese, and a BMI greater than 40.0 kg/m2 is considered morbidly obese (MORBID OBESITY).
D001835	Body Weight	The mass or quantity of heaviness of an individual. It is expressed by units of pounds or kilograms.	Body Weights,Weight, Body,Weights, Body
D003367	Cotinine	The N-glucuronide conjugate of cotinine is a major urinary metabolite of NICOTINE. It thus serves as a biomarker of exposure to tobacco SMOKING. It has CNS stimulating properties.	Scotine
