title: Elimination kinetics of isoniazid in the newborn infant.
abstract: The elimination of isoniazid was followed in 2 newborn infants who had received the drug transplacentally, and in 1 of the mothers. The half-time for serum elimination for mother No. 1, babies No. 1 and 2 were calculated as 3.0, 7.8 and 19.8 h, respectively. Near equality existed between maternal and newborn serum isoniazid concentrations. Additional studies are required to determine the acetylation capacity of newborns.
