Research Papers that Mention the Interaction
“We have recently reported the ability of L-tyrosine (L-TYR) to potentiate the anorectic activity of various mixed-acting sympathomimetics including phenylpropanolamine (PPA), l-ephedrine (EPH) and d-amphetamine (AMP).”
L-tyrosine fails to potentiate several peripheral actions of the sympathomimetics“Increases in motor activity following low doses of amphetamine (0.75-1.5 mg/kg) in casein control mice were antagonized by dietary L-tyrosine, but a higher dose of d-amphetamine (3 mg/kg) interacted with the addition of L-tyrosine producing an increase in motor activity.”
“ L-TYR (200 mg/kg) significantly potentiated the anorectic activity of phenylpropanolamine, (-)-ephedrine and (+)-amphetamine by 48, 50 and 37%, respectively.”
“This was correlated with an attenuation in the ability of (+)-amphetamine to stimulate [3H]dopamine formation from [3H]tyrosine in rat striatal slices of these nicotine-treated animals.”
