Ten volunteers carried a 10 mg 24 h -1 transdermal glyceryl trinitrate (GTN) patch for 24 h before moderate exercise. Plasma GTN-concentration increased significantly (P less than 0.05) by 19% to peak value at 15 min. Two hours after patch renewal repeat exercise increased GTN concentration by 56% (P less than 0.001). The two nitrate-concentration curves differed significantly (P less than 0.0001). Thus, change of patch augmented nitrate availability during exercise.
十名志愿者在进行适度运动前24小时佩戴10毫克/24小时的经皮硝酸甘油(GTN)贴片。血浆GTN浓度在15分钟时显著增加(P<0.05),增幅达19%,达到峰值。更换贴片两小时后,重复运动使GTN浓度增加了56%(P<0.001)。两条硝酸盐浓度曲线差异显著(P<0.0001)。因此,更换贴片增加了运动期间硝酸盐的可用性。
