The effect of physical exercise on plasma nicotine concentrations was studied in eight healthy subjects treated with a nicotine patch releasing 14 mg 24 h-1. After 11 h of patch application, plasma nicotine concentrations were measured before and after 20 min of moderate bicycle exercise, or 20 min of rest. Mean plasma nicotine concentration increased from 9.8 to 11.0 ng ml-1 (P = 0.015) during physical exercise, and fell non-significantly from 10.5 to 10.2 ng ml-1 during rest. The increase in plasma nicotine concentration during exercise is similar to that observed for transdermal nitroglycerin, and may be related to an exercise-induced increase in blood flow in the patch area.
在8名使用24小时释放14毫克尼古丁贴片的健康受试者中,研究了体育锻炼对血浆尼古丁浓度的影响。在贴片使用11小时后,在进行20分钟适度自行车运动或20分钟休息前后测量血浆尼古丁浓度。体育锻炼期间,平均血浆尼古丁浓度从9.8纳克/毫升增加到11.0纳克/毫升(P = 0.015),休息期间从10.5纳克/毫升降至10.2纳克/毫升,下降不显著。运动期间血浆尼古丁浓度的增加与经皮硝酸甘油观察到的情况相似,可能与运动引起的贴片区域血流增加有关。
