Abstract
Zinc absorption from the alimentary tract, as revealed by serum zinc concentration, was studied in a group of 10 patients (age 37.7±5.1 yr) with moderate and severe untreated primary arterial hypertension before and after a 30-d treatment with perindopril 4 mg/d. Blood pressure was 177.33±16.24/111.33±15.26 mm Hg before and 143.41±17.34/91.29±12.54 mm Hg after treatment (p<0.05/p<0.05). Nine persons (age 37±6.2 yr) with normal blood pressure (121.33±9.9/78±5.23 mm Hg) were the control group. Blood samples were taken from the ulnar vein at 8.00 am (0 h), before taking zinc orally (one tablet of Zincas (zinc aspartate), containing 5 mg Zn2+) and at 1, 3, and 6 h after the dose. Serum zinc concentration in control and hypertensive group (before treatment) were initially 15.47±6.26 versus 15.99±5.65 (NS), 19.37±6.40 versus 20.83±4.48 (NS) after 1 h, 17.91±4.76 versus 31.32±10.49 (p<0.003) after 3 h, and 15.32±5.47 versus 17.87±6.56 (NS) after 6 h. Maximal increase of Zn was 4.77±2.10 versus 17.53±4.13, respectively (p<0.001). In the hypertensive group, serum Zn before and after perindopril treatment was initially 15.98±5.65 versus 14.81±3.11 (NS), 20.83±4.48 versus 18.17±2.50 (NS) after 1 h, 31.32±10.49 versus 22.94±5.80 (NS) after 3 h, 17.53±4.13 (p<0.001) after 6 h. Maximal increase of Zn before treatment was 17.53±4.13 versus 9.17±4.67 (p<0.017) after treatment. The following conclusions were reached: (1) In patients with primary arterial hypertension, an increased zinc absorption from alimentary tract was found; (2) A 30-d perindopril treatment 4 mg/d orally decreased zinc absorption in these patients.
