1 The effect of pregnancy on the binding of phenytoin and phenobarbitone to serum proteins was studied in normal women and in drug treated epileptic women. 2 The binding of both drugs was reduced during pregnancy. The reduction correlated positively with the gestational age and negatively with the serum albumin concentration. 3 In spite of the increase in unbound fraction, both the total and free serum concentrations of phenytoin were decreased in late pregnancy.
