Pivagabine
Pivagabine, also known as N-pivaloyl-γ-aminobutyric acid or N-pivaloyl-GABA, is an antidepressant and anxiolytic drug which was introduced in Italy in 1997 for the treatment of depressive and maladaptive syndromes. But it was discontinued in Italy. Originally believed to function as a prodrug to GABA, pivagabine is now believed to act somehow via modulation of corticotropin-releasing factor.
