Aceglutamide (brand name Neuramina), or aceglutamide aluminum (brand name Glumal), also known as acetylglutamine, is a psychostimulant, nootropic, and antiulcer agent that is marketed in Spain and Japan. It is an acetylated form of the amino acid L-glutamine, the precursor of glutamate in the body and brain. Aceglutamide functions as a prodrug to glutamine with improved potency and stability.
