Indication
For the relief of nicotine withdrawal symptoms and as an aid to smoking cessation

Pharmacology
Nicotine, the primary alkaloid in tobacco products binds stereo-selectively to nicotinic-cholinergic receptors on autonomic ganglia, the adrenal medulla, neuromuscular junctions and in the brain. Nicotine exerts two effects, a stimulant effect exerted at the locus ceruleus and a reward effect in the limbic system. Itranvenous administration of nicotine causes release of acetylcholine, norepinephrine, dopamine, serotonine, vasopressin, beta-endorphin and ACTH. Nicotine is a highly addictive substance. Nicotine also induces peripheral vasoconstriction, tachycardia and elevated blood pressure. Nicotine inhalers and patches are used to treat smoking withdrawl syndrome. Nicotine is classified as a stimulant of autonomic ganglia.

Mechanism Of Action
Nicotine binds to the nicotinic acetylcholine receptor. Stimulation of nicotinic receptors leads to a variety of cholinergic and adrenergic effects; tachycardia or bradycardia mediated by either stimulation or interference with sympathetic or parasympathetic pathways, stimulation of receptors in the carotic and aortic bodies, release of epinephrine from the adrenal medulla, and stimulation of the chemoreceptor-trigger zone.

Absorption
Absorption of nicotine through the buccal mucosa is relatively slow and the high and rapid rise followed by the decline in nicotine arterial plasma concentrations seen with cigarette smoking are not achieved with the inhaler. About 10% of absorbed nicotine is excreted unchanged in urine.

Interactions
Interactions for Nicotine:

Physiological changes resulting from smoking cessation, with or without nicotine replacement, may alter the pharmacokinetics of certain concomitant medications, such as tricyclic antidepressants and theophylline. Doses of these and perhaps other medications may need to be adjusted in patients who successfully quit smoking.
