Abstract: This invention relates to a transdermal patch in the form of a layer complex, comprising a backing layer, a drug-reservoir layer comprising pharmacologically active ingredients and pharmaceutically acceptable adjuvants, and a release liner covering the drug-reservoir layer, characterized in that the drug-reservoir layer comprises isosorbide dinitrate and Bisoprolol at a ratio of 1:3 to 3:1 by weight, as the pharmacologically active ingredients. Animal tests show that said patch can reduce the elevation of T wave of cardiogram, the increase of the level of myocardial enzyme in blood serum, and the extension of the range of myocardial infarction caused by ligating the coronary artery in animals. Results show that said patch exhibits a considerable synergistic effect in the treatment of cardiovascular diseases and has good preventive and therapeutic effects on several adverse events on heart.

Abstract: There is provided a method for treating the surface of metals such as nickel based or high alloy steels, austenitic and ferritic stainless steels, copper and aluminum alloys to increase their corrosion resistance by modification of the metal surfaces to inhibit cathodic corrosion processes. In a single step treatment process the metals are immersed into a heated aqueous composition containing a rare earth salt substantially free of any halide compound. Increased corrosion resistance is obtained using nitrates of yttrium, gadolinium, cerium, europium, terbium, samarium, neodymium, praseodymium, lanthanum, holmium, ytterbium, dysprosium, and erbium nitrates. The rare earth salt is present in the range from about 2% by weight to saturation of the solution. The composition includes a pH-modifying substance such as nitric acid to adjust the pH in the range 0.5 to about 6.5 to attack the surface to remove oxides facilitating deposition of the rare earth.
