Low birth weight preterm infants with suspected infection were administered gentamicin intramuscularly every 18 h (2.5 mg/kg) or 24 h (3.0 mg/kg). For both dosage regimens plasma gentamicin levels were monitored during a dosage interval on three separate occasions over a 10 day period. Both regimens gave satisfactory plasma concentrations and there was no important statistically significant difference between the two. The body clearance of gentamicin correlated with gestational age (r=0.76, p<0.01). The results indicate either regimen may be useful in the clinical situation but from a practical standpoint administration every 24 h may be easier to comply with then every 18 h.
