Urinary excretion of zinc in patients with essential arterial hypertension

: We report the finding of an increase in urinary zinc excretion in patients suffering from essential arterial hypertension; we find no clear explanation for this phenomenon. However, it merits a more thorough study, such as a comparison of zinc metabolism as altered by the hypertensive process. Also, urinary zinc excretion before and after (6 months) Captopril administration is reported.
