We conducted a 2-sample pharmacokinetic study of oseltamivir in 12 premature infants. Oseltamivir 1 mg/kg/dose twice daily in infants <38 weeks postmenstrual age (n=8) resulted in oseltamivir carboxylate exposure comparable to previously published pediatric data, which helps prospectively validate this regimen. Oseltamivir 3 mg/kg/dose once daily in premature infants >38 weeks postmenstrual age (born prematurely but chronologically past term, n=4) resulted in similar oseltamivir and oseltamivir carboxylate exposure. Although these results suggest persistence of immature renal function in this subgroup, further pharmacokinetic/pharmacodynamic description is required to confirm the appropriateness of this regimen.
我们对 12 名早产儿进行了奥司他韦的两样本药代动力学研究。对于<38 周龄的婴儿(n=8),每日两次给予奥司他韦 1mg/kg 剂量,其奥司他韦羧酸的暴露量与先前发表的儿科数据相当,这有助于前瞻性验证该方案。对于>38 周龄的早产儿(虽然早产,但已过预产期,n=4),每日一次给予奥司他韦 3mg/kg 剂量,奥司他韦和奥司他韦羧酸的暴露量相似。尽管这些结果表明该亚组的肾功能不成熟持续存在,但需要进一步的药代动力学/药效学描述来确认该方案的适当性。
