II. Indications
III. Physiology: Nicotine
- Nicotine is a plant alkaloid extracted from Tobacco, used as an addictive CNS stimulant, as well as an Insecticide
- Nicotine Activity
- See Nicotinic Acetylcholine Receptor
- Binds nicotinic AcetylcholineGanglionic receptors and at Neuromuscular Junctions (stimulatory at low dose, inhibitory at high dose)
- Stimulates Epinephrine release from the Adrenal Medulla, and CNS Neurotransmitter release (e.g. Acetylcholine, Dopamine, Norepinephrine)
- Results in peripheral Vasoconstriction, Tachycardia, and elevated Blood Pressure
- Chemoreceptors may also be stimulated causing Nausea and Vomiting
IV. Approach
- Eight week course is sufficient with little added benefit to longer use
- Nicotine Replacement may be used in combination
- Controller medication (long-acting): Nicotine Patch
- Rescue medication (short acting): Nicotin Gum, Nicotine Lozenge, Nicotine Inhaler
-
Tobacco and Nicotine Replacement overlap
- Best to quit simultaneously with starting Nicotine Replacement
- However, now considered safe (although not ideal) to taper Tobacco use while initiating Nicotine Replacement
- Simultaneous use was considered a risk for coronary events
- Now appears that smokers will self titrate their Nicotine levels
- When Tobacco is still being used, Nicotine Replacement is reduced to maintain a constant Nicotine level
V. Preparations: Long acting
-
Nicotine Patch (e.g. Nicoderm, Nicotrol, Habitrol)
- Best in white, non-obese with low Nicotine dependence
- Lerman (2004) Ann Intern Med 140:426-33 [PubMed]
VI. Preparations: Short-acting
-
Nicotine Gum (Nicorette)
- Delays weight gain compared with other options
- May be preferred in cessation of chewing Tobacco
- Consider using in combination with the patch
-
Nicotine Nasal Spray (Intranasal Nicotine)
- Best in obese heavy smokers and non-white patients
- Lerman (2004) Ann Intern Med 140:426-33 [PubMed]
- Nicotine Inhaler (Nicotrol Inhaler)
- Nicotine Lozenge
VII. Management: Adjunctive medications
- See Tobacco Cessation
-
Varenicline (Chantix)
- More effective than Bupropion in Tobacco Cessation
-
Bupropion
- Consider in comorbid Major Depression when not contraindicated (esp. Seizure Disorder)
- Use in combination with Nicotine Replacement and other measures
- Mecamylamine (Inversine, Vecamyl)
- Rarely used in U.S. for Tobacco Cessation
- Increases abstinence rates with Nicotine Replacement
- Rose (1994) Clin Pharmacol Ther 56:86-99 [PubMed]
IX. Precautions
- Avoid Electronic Cigarette (E-Cigarette)
- Other standard Nicotine Replacement forms are well studied, regulated and preferred over E-Cigs
- Inadequate safety available for e-cig devices
- Unknown safety of inhaled vapor (e.g. propylene glycol, lead, Arsenic, formaldehyde, Hydrogen cyanide)
- E-cigs are commonly continued indefinitely (and often with continued Tobacco Smoking in up to 50%)
- If used, plan a taper schedule and e-cig quit date (e.g. 3 months after starting)
- Avoid Hookah Pipe (Tobacco smoke drawn through water before inhalation)
- Water does not filter Tobacco-related toxins
- Hookah users tend to smoke for longer and have greater exposure
