Iomazenil (also known as Ro16-0154, benzodine) is a partial inverse agonist of central-type benzodiazepine receptors (BZR) which binds specifically to BZR with high affinity and a potential treatment for alcohol abuse. The compound was introduced in 1989 by pharmaceutical company Hoffmann-La Roche as an Iodine-123-labelled SPECT tracer for imaging benzodiazepine receptors (GABAA receptors) in the brain.
