尼古丁袋 (NP) 通过口腔吸收输送尼古丁,为吸烟提供一种潜在的减少危害的替代方案. 然而,4毫克的NP提供了与香烟相似的总尼古丁暴露,引发了对依赖的担忧,特别是在青少年营销方面.
科学领域:
- 药理学和毒理学 药理学和毒理学
- 尼古丁产品 研究 研究 尼古丁产品
- 公共卫生 公共卫生
背景情况:
- 尼古丁袋 (NP) 正成为一种新的尼古丁输送系统.
- 它们被推销为可燃烟草产品的不那么有害的替代品.
- 与传统烟草相比,关于它们的药理动力学概况的数据有限.
研究的目的:
- 审查和综合有关尼古丁袋的药理动力学现有证据.
- 为了比较NP的尼古丁吸收与传统的烟草产品,如香烟和湿鼻烟.
- 评估NP可能导致尼古丁依赖的潜力.
主要方法:
- 在主要数据库 (Medline,Embase,CENTRAL,Scopus) 进行了系统的文献搜索.
- 包括的研究评估了成年人的药理动力学参数 (总暴露量,峰值度,峰值时间).
- 对随机对照试验和交叉试验的数据进行了元分析.
主要成果:
- 与香烟相比,NP的尼古丁总暴露量因强度而异:较低为1.5-2mg,相似为3.5-4mg,较高为≥8mg.
- 一项元分析表明,4mg的NP提供了91.7%的香烟尼古丁暴露.
- 与香烟相比,NP的尼古丁度峰值较低,并以后实现.
结论:
- 尽管口腔吸收,4mg的NP提供了与香烟相比的总尼古丁暴露,尽管吸收速度较慢,峰值度较低.
- 药物动力学特征,加上吸引人的口味和营销,表明尼古丁依赖的风险,特别是在年轻的娱乐用户中.
- 需要进一步的研究才能充分了解NP作为减少危害的工具的长期有效性和安全性.

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...
