    • A method for determining and demonstrating the role of vasodilator chemical agents in the development and practice of transdermal drug delivery systems. Vasodilator chemicals applied topically dilate the blood vessels in the skin tissue, which have been shown to facilitate or inhibit systemic or skin tissue deposition of drug substances. The level of stimulation and/or inhibition has been found to be dependent on the concentration and the identity of the specific vasodilator chemical(s) used as well as the drug molecule(s) to be delivered. This work teaches the need to consider specific formulation requirements when dealing with vasodilator chemicals for the creation of successful delivery vehicles in the transdermal drug delivery system. These requirements for very low concentrations of vasodilators were an unexpected and a surprise finding, in contrast to the concentrations of the vasodilators typically used to elicit an increase in skin blood flow.
    • 一种确定和证明血管扩张剂化学药剂在透皮给药系统开发和实践中的作用的方法。 施用的血管扩张剂化学品局部地扩张皮肤组织中的血管,已经显示出促进或抑制药物物质的全身或皮肤组织沉积。 已经发现刺激和/或抑制水平取决于所使用的特定血管扩张剂化学物质的浓度和特征以及待递送的药物分子。 这项工作教导了在处理血管扩张剂化学品以在透皮药物递送系统中创造成功的递送载体时,需要考虑具体的配方要求。 对于非常低浓度的血管扩张剂的这些要求是意想不到的和惊奇的发现,与通常用于引起皮肤血流增加的血管扩张剂的浓度相反。
