Cyclazodone is a centrally acting stimulant drug developed by American Cyanamid Company in the 1960s. The drug is related to other drugs such as pemoline and thozalinone. It displayed a favorable therapeutic index and margin of safety in comparison to most other pemoline derivatives. The patents concluded that cyclazodone possessed properties efficacious in reducing fatigue and as a potential anorectic. Structural congeners of pemoline have been described as "excitants with unique properties distinguishing them from the sympathomimetic amines" whilst displaying less stimulatory activity and toxicity compared to amphetamine.
