DRUG FOR TREATING VASCULAR DISEASE OR DRUG FOR CONTROLLING CELL PROLIFERATION COMPRISING RIFAMYCIN DERIVATIVE AS THE ACTIVE INGREDIENT

摘要

It is intended to provide a drug for treating a vascular disease or a drug for controlling cell proliferation to be used for preventing and treating a vascular disease such as restenosis after percutaneous angioplasty. This problem can be solved by a drug for treating a vascular disease or a drug for controlling cell proliferation comprising as the active ingredient a Rifamycin derivative which strongly inhibits the proliferation of vascular smooth muscle compared with vascular endothelial cells. Such preparations, etc. comprising the Rifamycin derivative as the active ingredient are useful in preventing or treating vascular diseases (for example, arteriosclerosis, aneurysm, false aneurysm, arterial dissection, an inflammatory arterial disease, a non-inflammatory arterial disease, hemodialysis shunt, restenosis and reobstruction after percutaneous angioplasty).
