3-Methoxy-4-hydroxyphenylethyleneglycol sulfate
3-Methoxy-4-hydroxyphenylethyleneglycol sulfate (MHPG-SO4) is the major metabolite of noradrenaline in serum. Chronic schizophrenics have lower serum levels than healthy individuals. Treatment of both groups with 7 daily 3-mg doses of haloperidol caused similar decreases in MHPG-SO4 concentration (PMID: 7343757). In human urine, MHPG-SO4 constitutes 44\\% of the total 3-methoxy-4-hydroxyphenylethylene glycol (PMID: 7379456). 3-methoxy-4-hydroxyphenylethyleneglycol sulfate (MHPG-SO4) is the major metabolite of noradrenaline in serum. Chronic schizophrenics have lower serum levels than healthy individuals. Treatment of both groups with 7 daily 3-mg doses of Haloperidol caused similar decreases in MHPG-SO4 concentration.
