Calcium channel blocker- (CCB-) associated peripheral edema does not resolve without CCB discontinuation or dose reduction. However, renin-angiotensin system (RAS) inhibitors have been reported to be effective for CCB-associated edema. We report a case of vasospastic angina with refractory CCB-associated edema. A 78-year-old man had refractory edema induced by a CCB. It was successfully treated with tolvaptan, an active vasopressin V2 receptor antagonist. The aim of this case report is to understand the mechanism and treatment of CCB-associated peripheral edema and how tolvaptan affects peripheral edema.
钙通道阻滞剂(CCB)相关的外周性水肿若不停用CCB或降低剂量则不会消退。然而,有报道称肾素-血管紧张素系统(RAS)抑制剂对CCB相关的水肿有效。我们报告一例患有难治性CCB相关水肿的血管痉挛性心绞痛病例。一名78岁男性因CCB诱发难治性水肿。使用活性血管加压素V2受体拮抗剂托伐普坦成功治愈。本病例报告的目的是了解CCB相关外周性水肿的机制和治疗方法,以及托伐普坦如何影响外周性水肿。
