title: [Phenytoin kinetics in toxic serum levels].
abstract: After discontinuing Phenytoin, the elimination kinetics was determined in 12 patients with toxic serum levels of more than 30 micrograms/ml. The half-lives of the elimination were between 72 and 122 h (97 h). The Michaelis constant amounted to 16,3 +/- 5,6 micrograms/ml and per day and the maximum rate of metabolism 9,9 +/- 1,1 microgram/ml and per day. The elimination half-lives was dependent on the concentration: the higher the serum concentration the longer the half-live. A method applicable in general practice for determining the course of the serum level with initial values of more than 30 micrograms/ml was described.
