毒理性
阿斯曲罗南具有与其他β-内酰胺类抗生素相似的全身毒性,但目前尚不清楚它是否可以像青霉素或头孢菌素一样引起肝脏损伤。在高剂量、静脉注射阿斯曲罗南治疗期间(10%至38%),无症状的血清转氨酶升高是常见的。酶异常通常是轻至中度的、无症状的、自限性的,不需要停药。与其它比较抗生素相比,阿斯曲罗南治疗期间酶升高的发生率略高。由于没有报告单个病例,因此可以认为由阿斯曲罗南引起的明显肝损伤和黄疸的情况极为罕见。因此,关于损伤的潜伏期或模式没有数据。有报道称在开始使用阿斯曲罗南后3到5天内出现明显的转氨酶升高的情况,但这些病例没有黄疸,且在停药后迅速恢复。
Aztreonam has systemic toxicities that are similar to those of other beta lactam antibiotics, but it is unclear whether it can cause hepatic injury similar to that of the penicillins or cephalosporins. Asymptomatic serum aminotransferase elevations are common during high dose, intravenous aztreonam therapy (10% to 38%). The enzyme abnormalities are usually mild-to-moderate, asymptomatic, self-limited and not requiring drug discontinuation. Enzyme elevations occur slightly more commonly during aztreonam therapy than with other comparative antibiotics. Cases of frank liver injury and jaundice attributable to aztreonam must be extremely rare as no individual cases have been reported. For this reason, there is no data regarding the latency or pattern of the injury. Instances of marked aminotransferase elevations within 3 to 5 days of starting aztreonam have been reported, but these cases were without jaundice and resolved rapidly once the drug was stopped.
