PROBLEM TO BE SOLVED: To provide a novel arteriosclerosis drug that controls infiltration of macrophage into an artery and is thereby capable of controlling thickening and fibrosis of aortic tunica media. SOLUTION: The arteriosclerosis drug includes nitroso nifedipine and a nitroso nifedipine derivative such as nitroso-nisoldipine nitroso-nimodipine nitroso-nicardipine and nitroso-nitrendipine nitroso nifedipine as active ingredients. The drug can control infiltration of macrophage into an arte...
