在使用磷酸二酯酶(PDE)-5抑制剂后,非ARTERIT性前部缺血性视神经病变(NAION)引起的视力丧失已有报道。1-9那些认为因果关系的人引用了原因(服用药物)和所谓的效果(NAION)之间的时间关系(半小时到36小时);提出的降低血压减少视神经血液供应的机制;先前报告的视觉症状(例如一过性蓝视觉)是这些药物的副作用;以及罕见的再挑战案例。为了回应最近媒体对NAION和西地那非(伟哥)可能相关的一系列报道,食品和药物管理局(FDA)已经批准了这些药物(包括西地那非、[vardena关]Levitra和[他达拉非]Cialis)的新标签,将NAON的信息包括在内。根据FDA的网站,截至2005年5月18日,已有43例使用PDE-5抑制剂后的ION被报告给FDA的不良事件报告系统。在这43例中,38例为西地那非,4例为他达拉非,1例为伐地那非。大多数人(43人中的25人)被推定患有NAION。43例中有36例视力丧失,其中26例为“持续性或永久性”视力丧失。在19例西地那非、4例他达拉非和1例伐地那非病例中发现了时间关系。据报道,5例西地那非和1例他达拉非患者出现了复发的眼部症状。
VISUAL LOSS FROM NONARTERITIC ANTERIOR ISCH-emic optic neuropathy (NAION) has been reported after the use of phosphodiesterase (PDE)-5 inhibitors. 1–9 Those that argue a causal association cite a temporal relationship (half an hour to 36 hours) between the cause (taking the drug) and purported effect (NAION); a suggested mechanism of lowered blood pressure reducing the blood supply to the optic nerve; prior reports of visual symptoms (for example transient blue vision) as side effects of these drugs; and rare rechallenge cases. In response to a recent flurry of lay press coverage about the possible association of NAION and sildenafil (Viagra), the Food and Drug Administration (FDA) has approved new labeling for these drugs (including sildenafil,[vardenafil] Levitra, and [tadalafil] Cialis) to include information on NAION.According to the FDA Web site, 10 as of May 18, 2005, 43 cases of ION after the use of PDE-5 inhibitors had been reported to the FDA’s Adverse Event Reporting System. Of these 43 cases, 38 were sildenafil, four were tadalafil, and one was vardenafil. Most (25 of 43) were presumed to have had NAION. Thirty-six of the 43 cases had visual loss, and 26 of these 36 had “continuing or permanent” loss. A temporal relationship was proposed in 19 sildenafil cases, four tadalafil cases, and the one vardenafil case. Recurrent ocular symptoms were reported in five sildenafil cases and one tadalafil case.
