Pharmacological Index |

Smoking Cessation Aid |

|
|
Use |
|
Treatment to aid smoking cessation for the relief of nicotine withdrawal
symptoms |

|
|
Pregnancy Risk
Factor |
|
D (transdermal); X (chewing gum) |

|
|
Contraindications |
|
Hypersensitivity or allergy to nicotine or any components of the system the
patient will be using; immediately post-MI; life-threatening arrhythmias; severe
or worsening angina; active temporomandibular joint disease (gum only);
pregnancy |

|
|
Warnings/Precautions |
|
The risk versus the benefits must be weighed for each of these groups:
patients with CAD, serious cardiac arrhythmias, vasospastic disease. Use caution
in patients with hyperthyroidism, pheochromocytoma, or insulin-dependent
diabetes. Safety and efficacy have not been established in pediatric patients.
Cautious use of topical nicotine in patients with certain skin diseases.
Hypersensitivity to the topical products can occur. Dental problems may be
worsened by chewing the gum. Urge patients to stop smoking completely when
initiating therapy. |

Adverse
Reactions |
|
Chewing gum:
>10%:
Cardiovascular: Tachycardia

belching, increased appetite

Overdosage/Toxicology |
|
Symptoms of overdose include nausea, vomiting, abdominal pain, mental
confusion, diarrhea, salivation, tachycardia, respiratory and cardiovascular
collapse
Treatment after decontamination is symptomatic and supportive; remove patch,
rinse area with water and dry, do not use soap as this may increase absorption.

|
Drug
Interactions |
|
CYP2B6 and 2A6 enzyme substrate; CYP1A2 enzyme inducer
Cimetidine increases nicotine concentrations; therefore, may decrease amount
of gum or patches needed.
Bupropion: Monitor for treatment-emergent hypertension in patients treated
with the combination of nicotine patch and bupropion. |

Stability |
|
Store inhaler cartridge at room temperature not to exceed
30°C (86°F); protect cartridges from
light |

Mechanism of
Action |
|
Nicotine is one of two naturally-occurring alkaloids which exhibit their
primary effects via autonomic ganglia stimulation. The other alkaloid is
lobeline which has many actions similar to those of nicotine but is less potent.
Nicotine is a potent ganglionic and central nervous system stimulant, the
actions of which are mediated via nicotine-specific receptors. Biphasic actions
are observed depending upon the dose administered. The main effect of nicotine
in small doses is stimulation of all autonomic ganglia; with larger doses,
initial stimulation is followed by blockade of transmission. Biphasic effects
are also evident in the adrenal medulla; discharge of catecholamines occurs with
small doses, whereas prevention of catecholamines release is seen with higher
doses as a response to splanchnic nerve stimulation. Stimulation of the central
nervous system (CNS) is characterized by tremors and respiratory excitation.
However, convulsions may occur with higher doses, along with respiratory failure
secondary to both central paralysis and peripheral blockade to respiratory
muscles. |

|
|
Pharmacodynamics/Kinetics |
|
Intranasal nicotine may more closely approximate the time course of plasma
nicotine levels observed after cigarette smoking than other dosage forms
Absorption: Transdermal: Slow
Metabolism: In the liver, primarily to cotinine, which is
1/5
as active.
Half-life, elimination: 4 hours
Time to peak serum concentration: Transdermal: 8-9 hours
Elimination: Via the kidneys; renal clearance is pH-dependent
|

|
|
Usual Dosage |
|
Gum: Chew 1 piece of gum when urge to smoke, up to 30 pieces/day; most
patients require 10-12 pieces of gum/day
Transdermal patch (patients should be advised to completely stop smoking upon
initiation of therapy): Apply new patch every 24 hours to nonhairy, clean, dry
skin on the upper body or upper outer arm; each patch should be applied to a
different site
Initial starting dose: 21 mg/day for 4-8 weeks for most patients
First weaning dose: 14 mg/day for 2-4 weeks
Second weaning dose: 7 mg/day for 2-4 weeks
Initial starting dose for patients <100 pounds, smoke <10
cigarettes/day, have a history of cardiovascular disease: 14 mg/day for 4-8
weeks followed by 7 mg/day for 2-4 weeks
In patients who are receiving >600 mg/day of cimetidine: Decrease to the
next lower patch size
Benefits of use of nicotine transdermal patches beyond 3 months have not been
demonstrated
Spray: 1-2 sprays/hour; do not exceed more than 5 doses (10 sprays) per hour;
each dose (2 sprays) contains 1 mg of nicotine. Warning: A dose of 40 mg
can cause fatalities. |

Patient
Information |
|
Use exactly as directed; do not use more often than prescribed. Stop smoking
completely during therapy.
Transdermal patch: Follow directions in package for dosing schedule and use.
Do not cut patches. Apply to clean, dry skin in different site each day. Do not
touch eyes; wash hands after application. You may experience dizziness or
lightheadedness; use caution driving or when engaging in tasks requiring
alertness until response to drug is known. For nausea, vomiting or GI upset,
small frequent meals, chewing gum, frequent oral care may help. Report
persistent vomiting, diarrhea, chills, sweating, chest pain or palpitations, or
burning or redness at application site.
Spray: Follow directions in package. Blow nose gently before use. Use 1-2
sprays/hour; do not exceed 5 doses (10 sprays) per hour. Excessive use can
result in severe (even life-threatening) reactions. You may experience temporary
stinging or burning after spray.
Pregnancy/breast-feeding precautions: Inform prescriber if you are
pregnant. Do not get pregnant during or for 1 month following therapy. Consult
prescriber for instruction on appropriate barrier contraceptive measures. This
drug may cause severe fetal defects. Do not breast-feed. |

Nursing
Implications |
|
Patients should be instructed to chew slowly to avoid jaw ache and to
maximize benefit; patches cannot be cut; use of an aerosol corticosteroid may
diminish local irritation under patches |
