1 The biliary excretion of erythromycin has been studied following parenteral administration in 23 patients. 2 Mean bile levels of the drug were approximately ten times higher than corresponding serum concentrations 1 h after i.v. (erythromycin lactobionate) and i.m. (erythromycin ethylsuccinate) injection. 3 Thus, unlike many antimicrobial agents, these compounds are well concentrated in the bile.
对23例患者进行肠外给药后,研究了红霉素的胆汁排泄情况。
静脉注射(乳糖酸红霉素)和肌内注射(琥乙红霉素)1小时后,药物的平均胆汁水平比相应的血清浓度高约10倍。
因此,与许多抗菌药物不同,这些化合物在胆汁中浓度很高。
