Effect of MW and dose on the balance between renal and non-renal elimination of UFH and LMWH: amount of ¹²⁵I-UFH (circles) and ¹²⁵I-nadroparin (squares) cleared from the blood according to the dose delivered. The solid lines show the total elimination. The curves have been decomposed by drawing a parallel to its linear part: the stippled lines (a) represent the non-saturable mechanism of disappearance and the dotted lines (b) represent the saturable mechanism of disappearance for the two test articles (nadroparin and UFH).
