ACC-9653, a prodrug of phenytoin synthesized to be water soluble, is converted to phenytoin by phosphatases. In this study, 43 patients received ACC-9653 IV or IM. Side effects were transient and minor. The conversion half-lives of ACC-9653 after intravenous and intramuscular administration averaged 8.4 and 32.7 minutes, respectively. Peak phenytoin concentrations occurred 42 minutes after IV and 151 minutes after IM administration.
