Background:
Smoking reduces HDL-C and its subfractions, and smoking cessation leads to normalization of these lipoproteins. Nicotine replacement therapy is an important weapon employed by those attempting to quit smoking. This study examined the effects of the transdermal nicotine patch ("patch") on lipoproteins.
Methods:
Ten male and 17 female smokers refrained from smoking for 77 days. The patch was utilized during the first 35 days and then removed for the remaining 42 days. Seven male and 9 female nonsmokers were controls.
Results:
HDL-C, HDL(2)-C, and HDL(3)-C levels were significantly lower in smokers when compared with controls. These differences were sustained during the initial 35 days when using the patch. Over the following 42 days, however, these lipoproteins normalized to values similar to those of control subjects. Females who quit smoking gained 2.1 kg after the patch was removed.
Conclusions:
It was concluded that nicotine as administered by the transdermal nicotine patch inhibits normalization of HDL-C, HDL(2)-C, and HDL(3)-C in those who have quit smoking. Removal of the patch results in normalization of these lipoproteins. The patch appeared to prevent weight gain among female subjects.

01:23Drugs 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 sympathetic or...

Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.
