In spite of the fact that smoking is the main cause of obstetric morbidity and mortality, 20% of North American women smoke during pregnancy. In Spain, this figure is as high as 30% to 35%. Treating smoking addiction in these patients should be the first and most important therapeutic measure undertaken by health professionals responsible for the care of pregnant women. All experts recommend the use of nicotine replacement therapy when more conservative treatments have failed. This article reviews the indications and contraindications for nicotine replacement therapy during pregnancy as well as other issues relating to the safety of this type of treatment.

Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating sympathetic or...
