title: Pharmacokinetics of a single dose of phenytoin in man measured by radioimmunoassay.
abstract: 1. Serum concentrations of phenytoin were studied by radioimmunoassay in five normal volunteers following a single oral dose of phenytoin sodium (100 mg). 2. Two distinct peaks were found at 2.5-3.5 and 10-12 h after ingestion. Maximum serum concentrations ranged from 1.56 mug/ml. The mean plasma half-life of the drug under these conditions was 9.81 +/- 0.66 (s.e. mean) hours.
