    • A composition for topical application to a part of the body comprises a vasodilator, for example glyceryl trinitrate, as active ingredient dissolved in a blend of volatile and non-volatile solvents of different solvating capacities for the vasodilator. The vasoldator is present in the composition at a concentration at or slightly below saturation, whereby evaporation of the volatile solvent in use will maintain the vasodilator at saturated or super-saturated concentrations in the residue, whereby the vasodilator will become saturated or supersaturated in the solvent remaining and, as the active ingredient passes through the skin and is absorbed in the bloodstream, and thus becomes depleted in the residual composition, continuing evaporation of volatile solvent will maintain the active ingredient substantially at saturation or supersaturation level in the residual composition throughout the major part of the absorption phase, thereby maximising absorption levels but at a moderate dosage level.
    • 用于局部施用于身体的一部分的组合物包含血管扩张剂,例如三水硝酸甘油酯,作为溶解在用于血管扩张剂的不同溶剂化能力的挥发性和非挥发性溶剂的共混物中的活性成分。 挥发物以组合物浓度存在于或稍低于饱和度,由此在使用中挥发性溶剂的蒸发将使血管扩张剂在残留物中保持饱和或超饱和浓度,由此血管扩张剂将在溶剂中变得饱和或过饱和 剩余的,并且由于活性成分通过皮肤并被吸收在血液中,并且因此变得耗尽残留组合物,挥发性溶剂的持续蒸发将使整个主要的残留组合物中的活性成分基本维持在饱和或过饱和水平 吸收阶段的一部分,从而使吸收水平最大化,但处于适度的剂量水平。
