Nicotine is widely used in pharmaceutical industries, especially for smoking cessation in the form of transdermal patches. Nicotine gel in the patches has limitations from nicotine instability and high volatility. Thus, a nicotine preservation technique is needed. In this study, a nicotine encapsulation process using methyl-β-cyclodextrin (MβCD) is investigated and compared with β-cyclodextrin (βCD) to evaluate the preservation and skin permeation of nicotine. The M06-2X/6-31G(d,p) density functional theory calculations indicate a 1:1 host–guest molar ratio for the inclusion complex of nicotine with βCD and MβCD, which have been validated by experimental studies. The encapsulation efficiencies of βCD and MβCD to encapsulate nicotine are 59.96% and 63.76%, respectively. The preservation study of the inclusion complexes compared to pure nicotine shows a stability improvement of nicotine after being encapsulated. After 21 days, the percentages of the nicotine/βCD and nicotine/MβCD inclusion complexes that remain are 89.32% and 76.22%, while only 65.56% of pure nicotine remains. Besides the one-hour skin permeation tests, the amounts of nicotine permeated through pig skin from the nicotine/βCD and nicotine/MβCD inclusion complex gels are 14 and 10 times as much as the pure nicotine gel, respectively. Therefore, the encapsulation of nicotine with βCD and MβCD can be used to enhance the stability and skin permeation application of nicotine-containing products. View Full-Text
