Hopantenic acid (homopantothenic acid) is a central nervous system drug. Formulated as the calcium salt, it is used in the Russian Federation for a variety of neurological, psychological and psychiatric conditions and sold as Pantogam (Russian: Пантогам).

Chemistry

Hopantenic acid is a homolog of pantothenic acid. While pantothenic acid is the amide of D-pantoate and β-alanine, hopantenic acid is the amide of D-pantoate and γ-aminobutyric acid (GABA). This change leads to an additional CH₂ in the molecule.
