  • MetabollsmMetabolised by hydroxylation to 4-hydroxyethinamate, which exists as stereoisomers, and conjugated with glucuronic acid.
  • Half life2 h
  • ExcretionAbout 40% of a dose is excreted in the urine in 24 h as trans-4-hydroxyethinamate or its glucuronide conjugate; only a small amount is excreted unchanged in the urine; 3- and 2-hydroxyethinamate have also been detected in urine.

  • CleranceN/A
  • ToxicitySymptoms of overdose include shortness of breath or slow or troubled breathing, slow heartbeat, severe weakness, chronic confusion, slurred speech, and staggering.. The estimated minimum lethal dose is 15 g but recovery has occurred after ingestion of as much as 28 g. Prolonged use of ethinamate may lead to dependence of the barbiturate–alcohol type. Blood concentrations greater than 100 mg/L have been associated with fatalities.
