title: Plasma phenytoin levels produced by various phenytoin preparations.
abstract: A cross-over study was conducted to compare the plasma phenytoin levels produced by different phenytoin preparations available in Australia. The preparations were found not to be equivalent, a liquid suspension product producing higher levels compared with capsule and tablet formulations. The clinical significance and possible explantation are discussed.
