Abstract
The level of norepinephrine in neuronal synapses is regulated in order to treat depression by administering a neutral amino acid composition to a human wherein an increased brain level of norepinephrine is effected when the composition contains increased amounts of tyrosine and/or phenylalanine. Increased or decreased brain levels of serotonin are obtained when the amino acid composition contains increased or decreased amounts of tryptophan. The neutral amino acid composition can be administered alone or concomitantly with a drug which increases or decreases noradrenergic neurotransmission.
Claims2
