the excretion of 3-methoxy-4-hydroxyphenylglycol ( mhpg ) , the urinary metabolite which may best reflect brain norepinephrine , was measured in eight depressed patients on a longitudinal basis during the administration of placebo , d- and 1-amphetamine ( 30 mg/day ) , lithium carbonate ( 0.9 - 2.1 g/day ) , and d- and 1-amphetamine together with lithium . d-amphetamine significantly decreased mhpg excretion .
