  • Look Inside


 A 66-year-old man with cerebral infarction, previous myocardial infarction and peripheral vascular disease was admitted to our hospital due to uncontrollable hypertension. He was diagnosed as a case of renovascular hypertension because of the 99% stenosis of his right renal artery and elevation of plasma rennin activity. Although systolic blood pressure was reduced 30mmHg after percutaneous transluminal renal angioplasty(PTRA), morning hypertension still remained. A morning administration of telmisartan(20mg) decreased the patient's blood pressure adequately during daytime, but worsened morning hypertension developed. However, an evening administration improved it. An increase in the dosage of telmisartan was not permitted because of a 30% increase in serum creatinine level. It was suggested that evening administration of telmisartan was effective in cases where the patient's condition allowed only small dose usage, such as in this case of residual hypertension after PTRA.
