Pantogam (hopantenic acid) is a nootropic drug currently used In Russia to treat chronic fatigue and various neurological diseases. The drug has neuroprotective, anxiolytic and anticonvulsant properties.

Pantogam works by activating GABA-A, GABA-B, and dopamine D2 receptors and is shown to stimulate the synthesis of acetylcholine.

Pantogam Active is a racemic modification of Pantogam. Hopantenic acid has two active Enantiomers, and Pantogam active has a different racemic composition with a higher content of L-enantiomer.
