Pharmacokinetics of oxatomide in preterm infants.

The pharmacokinetics and tolerability of oxatomide oral suspension were investigated in preterm infants to evaluate the feasibility of planning a further study to assess its antiinflammatory effects and its effectiveness in preventing chronic lung disease (CLD). Following the administration of oxatomide 1 mg/kg, the peak plasma concentration (Cmax), the elimination half-life (t1/2), the volume of distribution (Vd), and the area under the curve (AUC) 0-36 h were measured and the following results were obtained: 42.2 +/- 15 ng/ml at 2 h after oxatomide administration, 41.4 +/- 2.0 h, 37.4 +/- 4.2 l/kg, and 468 +/- 52 ng/ml/h, respectively. Our study, therefore, demonstrated that a dose of 1 mg/kg/day oxatomide was effective in reaching therapeutic plasma levels in preterm infants without inducing adverse effects.
