Optical Activity ( + / - )

Pemoline is a central nervous system stimulant. Pemoline is structurally dissimilar to the amphetamines and methylphenidate. Pemoline is generally considered dopaminergic, but its precise method of action hasn't yet been definitively determined. The interaction of pemoline with other drugs has not been studied in humans. The following are adverse reactions in decreasing order of severity within each category associated with pemoline: hepatic dysfunction, aplastic anemia, convulsive seizures, hallucinations, insomnia, anorexia and weight loss.

Originator

Curator's Comment: Pemoline was first synthesized in 1913 but its activity was not discovered until the 1930s.
