Serum and urine concentrations of ampicillin, amoxycillin, and flucloxacillin achieved after oral administration have been measured in 27 newborn infants. Compared with adults and children, newborn infants show a delay in achieving adequate blood concentrations, presumably due to delayed absorption. However most infants achieve therapeutic concentrations in the serum. Infected newborn infants should be given these antibiotics by intramuscular injection for the first dose, but thereafter oral therapy (25 mg/lg every 6 hours begun concomitantly) should be satisfactory. The better absorption of amoxycillin compared with ampicillin reported in adults has not been confirmed in the newborn infant.
对27名新生儿口服氨苄西林、阿莫西林和氟氯西林后的血清及尿液浓度进行了测定。与成人和儿童相比,新生儿达到足够血药浓度的时间有所延迟,推测是由于吸收延迟所致。然而,大多数婴儿血清中能达到治疗浓度。感染的新生儿首剂应通过肌肉注射给予这些抗生素,但之后口服治疗(每6小时25mg/kg,同时开始)应是令人满意的。在成人中报道的阿莫西林相比氨苄西林有更好的吸收情况,在新生儿中尚未得到证实。
