Tobacco Smoking, Nicotine, and Nicotine and Non-Nicotine Replacement Therapies
Heart Disease, 2001Tobacco smoking is associated with an increased risk for the development of coronary and pulmonary vascular diseases and smoking cessation will greatly reduce this risk. Nicotine replacement and nonnicotine modalities have been used alone and in combination to help in smoking cessation.

Chronopharmacokinetics of nicotine*
Clinical Pharmacology & Therapeutics, 1996For high-clearance drugs such as nicotine, hemodynamic changes throughout the day may be expected to influence the rate of metabolism.To assess the effects of meals and diurnal rhythms on nicotine clearance, an intravenous infusion of nicotine bitartrate was administered for 48 hours to 11 subjects.

Cochrane Database of Systematic Reviews, 2004
The proportion of people with schizophrenia who smoke is very high, and as a rule, they tend to be heavier smokers when compared to the general population and those with other psychiatric disorders. Nicotine, the psychoactive component in tobacco, is thought to produce psychological effects that help to alleviate psychotic symptoms.To examine the ...

NICOTINE POISONING WITH A SALT OF NICOTINE
Journal of the American Medical Association, 1939The reported instances of fatal nicotine poisoning according to Webster 1 and to Beeman and Hunter 2 are relatively infrequent. The nicotine insecticides are the usual preparations of nicotine used for suicidal purposes. To our knowledge there have been no reports of poisoning with a dry salt of nicotine.

British Journal of Addiction, 1989
SummaryIn recent years progress in basic neuropsychopharmacology and clinical addiction research have allowed the conclusion that tobacco smoking essentially represents an addiction to nicotine. Parallel to this work, experimental research in biochemistry, physiology and pharmacology has provided detailed descriptions of the structure and function of ...

Review: Nicotinic receptors and stages of nicotine dependence
Journal of Psychopharmacology, 2009Smoking is one of the leading causes of preventable death, where nicotine has been identified as the primary addictive constituent of tobacco. Consequently, there have been extensive investigations into the neuroadaptations that occur as nicotine dependence develops, where numerous neurological systems have been implicated. The focus of this review was

Thermal transfer to nicotine in the gas phase from neat nicotine, from various nicotine carboxylic acid salts, and from endogenous nicotine in Burley, Bright, and Oriental tobacco samples has been examined by thermogravimetric/differential thermal analysis/mass spectroscopy and evolved gas analysis.

Abstract A sensitive and specific radioimmunoassay of nicotine was developed using antisera raised against 6-(p-aminobenzamido) nicotine coupled to bovine serum albumin. Inhibition studies with various nicotine analogues revealed that the antisera are highly specific for both the N-methylpyrrolidine ring and the pyridine ring of nicotine, and ...
