Overview:
Cylert, pemoline, is a CNS stimulant prescribed for ADHD in children 6 years and older.
Cylert is suspected of causing hepatotoxicity, so regular liver tests are performed on those treated with it. Since receiving FDA approval in 1975, it has been linked with 21 cases of liver failure, of which 13 resulted in liver replacement or death.
In 2005, the Food and Drug Administration (FDA) withdrew approval for pemoline due to pressure from several public advocacy groups. A more potent analogue of pemoline, 4-methylaminorex has appeared as a black market drug with abuse potential similar to methamphetamine.
In March 2005, Abbott Laboratories (Cylert® marketer) had discontinued the production of Cylert arguing economic reasons
