Infusions of 50 mg of sulbactam per kg per day and 400 mg of ampicillin per kg per day in divided doses to infants and children with bacterial meningitis produced levels in cerebrospinal fluid approximately one-third those in serum. Concentrations in cerebrospinal fluid of 5.5 micrograms of sulbactam per ml and 16.0 micrograms of ampicillin per ml declined within a few days of therapy to 1.9 microgram of sulbactam per ml and 5.2 micrograms of ampicillin per ml.
对于患有细菌性脑膜炎的婴幼儿和儿童,每日每千克体重静脉输注50毫克舒巴坦和400毫克氨苄西林(分剂量给药)后,脑脊液中的药物浓度约为血清中的三分之一。治疗几天后,脑脊液中舒巴坦浓度从每毫升5.5微克降至每毫升1.9微克,氨苄西林浓度从每毫升16.0微克降至每毫升5.2微克。
