曲霉菌素治疗与血清酶异常的低发生率有关,尽管将这些升高归因于曲霉菌素一直很困难。尽管使用了数十年,但没有令人信服的案例表明急性肝损伤与曲霉菌素治疗有关。虽然曲霉菌素通常不被吸收,但在胃肠道炎症和损伤的患者中,低浓度的曲霉菌素可能会进入血液循环。尽管如此,曲霉菌素被认为非常安全,不太可能引起肝损伤。
Nystatin therapy has been associated with a low rate of serum enzyme abnormalities, although it has been difficult to attribute these elevations to nystatin. Despite its use for several decades, there have been no convincing cases of acute hepatic injury linked to nystatin therapy. While nystatin is usually is not normally absorbed, low concentrations may enter the circulation in patients with inflammation and damage to the gastrointestinal tract. Nevertheless, nystatin is considered very safe and is unlikely to cause hepatic injury.

/流行病学研究/ 比较了在第一孕期间涉及先天性异常分娩和不涉及先天性异常分娩之前,咪康唑、克霉唑、制霉菌素、杀念菌素、氨基acrine化合物和甲硝唑的处方频率。自发性流产前的处方与第一孕期间分娩的处方以及合法流产前的处方进行了比较。观察到任何这些药物与总体出生缺陷频率或分析的具体出生缺陷(心血管缺陷、口裂和脊柱裂)之间没有统计学上的显著关联。在4264次自发性流产中有250次咪康唑暴露,与55,736次分娩第一孕期间的2236次暴露相比,估计相对风险为1.4(95%置信区间为1.2-1.5)。在自发性流产中有112次使用克霉唑治疗,与分娩中的1086次相比,相对风险为1.4(95%置信区间为1.1-1.6)。相比之下,大量制霉菌素和氨基acrine化合物的暴露并没有显示出这种关联,这表明自发性流产是由咪唑类药物咪康唑和克霉唑引起的,而不是由所治疗的条件引起的。因为许多关联是在没有先前假设的情况下进行的检查,并且数据不足以显示在比较自发性流产与合法流产暴露时克霉唑的风险升高,这些发现被视为进一步研究的信号,而不是本身具有决定性。
/EPIDEMIOLOGY STUDIES/ Prescription frequencies in the first trimester were compared for miconazole, clotrimazole, nystatin, candicidin, aminacrine compounds, and metronidazole before deliveries involving congenital anomalies versus those not linked to congenital anomalies. Prescriptions before spontaneous abortions were compared with those in the first trimester of deliveries and with those before legal abortions. No statistically significant association was observed with any of these agents for the overall frequency of birth defects or for specific birth defects analyzed (cardiovascular defects, oral clefts, and spina bifida). Two hundred fifty miconazole exposures among 4264 spontaneous abortions, compared with 2236 in the first trimester of 55,736 deliveries, provided an estimated relative risk of 1.4 (95% confidence limits 1.2-1.5). One hundred twelve treatments with clotrimazole among the spontaneous abortions, compared with 1086 among the deliveries, provided a relative risk of 1.4 (95% confidence limits 1.1-1.6). In contrast, large numbers of exposures to nystatin and aminacrine compounds did not show this association, suggesting that spontaneous abortions are caused by the imidazole agents miconazole and clotrimazole rather than the condition being treated. Because many associations were examined without previous hypotheses, and because the data were inadequate to show an elevated risk for clotrimazole when comparing spontaneous with legal abortion exposures, these findings are considered to be a signal for further studies rather than definitive in themselves.
