Study Notes
Nicotine Distribution
- Nicotine reaches the brain within 8 seconds.
- Nicotine levels in the central nervous system (CNS) rise rapidly and then decline quickly due to redistribution to other tissues.
- Nicotine achieves a volume of distribution of approximately 1 L/kg
- Nicotine readily crosses the placenta and is also transmitted in small concentrations in breast milk.
Nicotine Metabolism
- Nicotine is primarily metabolized by the CYP450 system in the liver (80-90%).
- It is also metabolized to a lesser extent in the kidneys and lungs.
Respiratory compromise
- Respiratory compromise is a potential complication of nicotine poisoning.
Emesis in Nicotine Poisoning
- Inducing emesis (vomiting) is not recommended in cases of nicotine poisoning, as it may trigger seizures or respiratory depression.
Nicotine Dependence Treatment
- Nicotine dependence treatment, also known as smoking cessation therapy, aims to reduce the urge to consume nicotine and its associated health risks.
- Medications and behavioral support can be used to help individuals quit smoking.
Medication Options
- Nicotine Replacement Therapy (NRT) is a common treatment option for nicotine dependence.
- NRT is available in various forms: skin patches, nasal sprays, inhalers, chewing gum, and lozenges.
Behavioral Support
- Behavioral support can range from written information and advice to group therapy or individual counseling (in person, via phone, or online).
- Self-help materials are more effective than no support at all, but individual counseling is generally the most effective form of behavioral support.
