1 The pharmacokinetics and physiological effects of buprenorphine were studied in 12 newborn premature neonates (27 to 32 weeks gestational age) who were given a loading dose of 3.0 mug kg-1 of buprenorphine followed by an intravenous infusion of 0.72 mug kg-1 h-1 of buprenorphine. Plasma concentrations of buprenorphine were measured during the infusion, at steady-state and for 24 h after the cessation of the buprenorphine infusion.2 The mean steady-state plasma buprenorphine concentration (+/- s.d.) for an infusion rate of 0.72 mug kg-1 h-1 was 4.3 +/- 2.6 ng ml-1.3 Buprenorphine clearance was 0.23 +/- 0.07 l h-1 kg-1, the elimination half-life was 20 +/- 8 h and the volume of distribution was 6.2 +/- 2. 11 l kg-1.4 Small but significant falls were noted in systolic blood pressure at 6 h and heart rate at 1, 6 and 12 h after the administration of buprenorphine, but these did not appear to cause any clinical deterioration.5 Four of the 12 subjects studied required an increase in the infusion rate of buprenorphine to achieve adequate sedation.6 The results suggest that this dosing regimen of buprenorphine is safe but may not be as effective as other opioids in producing sedation and analgesia in premature newborns.
