Ocinaplon is an anxiolytic drug in the pyrazolopyrimidine family of drugs. Other pyrazolopyrimidine drugs include zaleplon and indiplon.

Ocinaplon has a similar pharmacological profile to the benzodiazepine family of drugs, but with mainly anxiolytic properties and relatively little sedative or amnestic effect.[1]

Mechanism of action

The mechanism of action by which ocinaplon produces its anxiolytic effects is by modulating GABAA receptors,[2] although ocinaplon is more subtype-selective than most benzodiazepines.[3]

Availability

Ocinaplon has not yet been marketed and as of 2007 is currently in clinical trials.[4]
