摘要
Methods for changing the delivery of an active ingredient to the vasculature of an animal by iontophoresis have the steps of adding a vasoactivator to a formulation with an active ingredient, coiontophoresing the vasoactivator and the active ingredient into the skin of an animal and establishing a concentration of the vasoactivator in the skin near the upper capillary loops thereof so that the blood flow is changed therethrough. The vasoactivator effectively changes the blood flow in the upper capillary loops of the vasculature in the skin of an animal. If the vasoactivator is a vasodilator, the blood flow is increased and when the vasoactivator is a vasoconstrictor, the blood flow is decreased. An iontophoretic delivery apparatus for use with a formulation for controlling iontophoretic transdermal administration of an active ingredient into the blood stream of the vasculature of an animal has a donor reservoir and an indifferent reservoir with an electric field therebetween for the flow of ions thereacross. The formulation is associated with the donor reservoir for coiontophoresis along the electric field to the indifferent reservoir. The vasoactivator in the formulation changes the blood flow in the upper capillary loops controlling the introduction of the active ingredient into the blood stream of the animal. A composition for coiontophoretic delivery has a solution of an active ingredient and a vasoactivator in a polar liquid.
