毒理性
前瞻性研究表明,一部分服用胆碱镁三水杨酸盐的患者至少会经历暂时的血清转氨酶升高。即使继续用药,这些情况也可能解决,尤其是如果减少了剂量。在高剂量下,可能会出现显著的转氨酶升高(>3倍升高),其模式类似于阿司匹林诱导的肝毒性。至少有一例临床上明显的肝损伤并伴有黄疸的报道,发病时间在开始服用三水杨酸盐后一周内,其特点是酶升高模式混合,并且病程可能严重。发热、皮疹和嗜酸性粒细胞增多并未发生,自身抗体也未出现。三水杨酸盐可能能够诱发易感儿童或青少年的Reye综合症,并且像阿司匹林一样,应避免在这一年龄组中使用。
Prospective studies show that a proportion of patients taking choline magnesium trisalicylate experience at least transient serum aminotransferase elevations. These may resolve even with drug continuation, particularly if the dose is reduced. Marked aminotransferase elevations (>3 fold elevated) can occur with high doses in patterns that resemble aspirin induced hepatotoxicity. At least one instance of clinically apparent liver injury with jaundice has been reported with onset within a week of starting trisalicylate and characterized by a mixed pattern of enzyme elevations and potentially severe course. Fever, rash and eosinophilia did not occur and autoantibodies were not present. Trisalicylate is probably capable of inducing Reye syndrome in a susceptible child or adolescent and, like aspirin, should be avoided in those age groups.
