1. A method for treating angina pectoris in a human, which method comprises:
- (a) placing on the skin of a human afflicted with angina pectoris a medical bandage comprising;
(1) a backing member that is substantially impermeable to the passage of a drug, one face of which forms the top of the bandage;
(2) a reservoir adjacent to the opposite face of the backing member, the reservoir comprising gelled silicone fluid, silicon dioxide, and a vasodilator having a group selected from the group consisting of ONO and ONO2 useful for treating angina pectoris;
(3) a rate controlling membrane adjacent and below the reservoir, which membrane is permeable to the passage of the vasodilator, controls its rate of release from the bandage and is in contact with the backing member to form a substantially fluid-tight medical bandage; and
,(4) a contact adhesive for holding the medical bandage on the skin; and
,(b) administering the vasodilator to the skin in a therapeutically effective amount for treating said angina pectoris.
