对羟基苯甲酸酯在一些药物中用作抗菌赋形剂。对羟基苯甲酸酯可能会对生殖产生不利影响。确定含有对羟基苯甲酸酯的药物是否会导致尿对羟基苯甲酸酯浓度升高。生育诊所的个人在评估/治疗期间提供了多个尿液样本,并报告了 24 小时使用药物和个人护理产品 (PCP) 的情况。重复测量模型比较了“暴露”和“未暴露”含对羟基苯甲酸酯药物的样品之间经比重调整后的尿对羟基苯甲酸甲酯、丙酯和丁酯浓度。 11 名参与者提供了 12 个暴露样本和 45 个未暴露样本,其中对羟基苯甲酸酯浓度没有差异。在调整五氯苯酚的使用后,七小时内使用与平均尼泊金甲酯 (P=0.11) 和丙酯 (P=0.10) 浓度分别增加 8.7 倍和 7.5 倍相关。然而,在移除一名有影响力的个体后,这些关联性分别下降至 1.3 倍(P=0.76)和 2.6 倍(P=0.34)。含有对羟基苯甲酸酯的药物在使用后数小时内会导致尿液中对羟基苯甲酸酯的浓度升高。
Parabens are used as antimicrobial excipients in some pharmaceuticals. Parabens may adversely affect reproduction. Determine whether paraben-containing medication contributes to high urinary paraben concentrations. Individuals at a fertility clinic provided multiple urine samples during evaluation/treatment and reported 24-hour use of medications and personal care products (PCP). Repeated measures models compared specific gravity-adjusted urinary methyl, propyl, and butyl paraben concentrations between samples “exposed” and “unexposed” to paraben-containing medication. Eleven participants contributed 12 exposed and 45 unexposed samples, among which paraben concentrations did not differ. Use within seven hours was associated with 8.7-fold and 7.5-fold increases in mean methyl (P=0.11) and propyl (P=0.10) paraben concentrations, respectively, after adjusting for PCP use. However, these associations decreased to 1.3-fold (P=0.76) and 2.6-fold (P=0.34), respectively, after removal of one influential individual. Paraben-containing medications contributed to higher urinary paraben concentrations within hours of use.
