Calculated (hypothetical) pharmacokinetic model depicting plasma levels of indomethacin during first postnatal week in an extremely low birth weight infant exposed to different prophylactic dosing regimens. (Using the weight of the infant as 500 g, indomethacin plasma levels were calculated applying following equations (Supplementary text): (1) Plasma concentration initial = dose(mg)/volume of distribution (L). (2) Volume of distribution of indomethacin = 0.28 × weight (kg) + 0.0041 × postnatal age in days (Weist et al. [15]). (3) Plasma concentration subsequent = plasma concentration initial × e−kt, k = 0.69/half-life, t = subsequent time in hours; indomethacin half-life = 94 h (Smith et al. [12]).
