Ripazepam (CI 683 or pyrazapon) is a pyrazolodiazepine that has anxiolytic effects. It is related to certain benzodiazepines such as zolazepam. In animal studies, it showed anxiolytic effects without sedative or depressant effects. In rats, it did not elicit a tumorigenic potential. Although ripazepam was found significantly superior to placebo and was well tolerated in neurotic patients, it has never been marketed for clinical use.
