Effect of agmatine on electrically and chemically induced seizures in mice.

Agmatine, an amine and organic cation, is formed by the decarboxylation of L-arginine by arginine decarboxylase. It binds to alpha(2)-adrenergic and imidazoline receptors. It blocks N-methyl-D-aspartate (NMDA) subtype of glutamate receptors and inhibits nitric oxide (NO) synthase.
