The patches arc characterized in that isosorbide nitrate is added as the active ingredient to tacky plasters containing as the essential ingredients styrene-isoprene-styrene block copolymers, rosin resins, liquid rubbers, antioxidants and oleic acid. More particularly, 15 to 25 %(w/w) of isosorbide nitrate is added to plasters containing 15 to 35 % of styrene-isoprene-styrene block copolymers, 35 to 55 % of rosin resins, 5 to 20 % of liquid rubbers, 0.1 to 2 % of antioxidants and 0.1 to 5 % of oleic acid.</p> |
