| Popis: | The aim of this study was to observe the effect of an 8-week treatment with amlodipine, alone or in combination with hormone replacement therapy (HRT), on blood pressure (BP), serum osteocalcin, bone-specific alkaline phosphatase (B-ALP) and urine deoxypiridinoline in postmenopausal osteoporotic women with mild-to-moderate arterial hypertension. Both conventional clinical BP measurements and ambulatory blood pressure monitoring (ABPM) were used. Twenty hypertensive menopausal women with osteoporosis were randomly divided in two groups according to the treatment regimens: amlodipine and amlodipine + HRT. Neither treatment regimen significantly changed bone formation or bone resorption markers. There were no significant differences in levels of serum and urinary calcium and phosphorous or serum cholesterol and low-density lipoprotein (LDL)-cholesterol after treatment with amlodipine alone or in combination with HRT. Triglycerides were significantly decreased and high-density lipoprotein (HDL)-cholesterol was significantly increased after amlodipine treatment. Both treatment regimens significantly decreased conventionally measured BP to a similar extent. Amlodipine given alone lowered the midline estimating statistic of rhythm (MESOR; mean 24-level) of systolic BP and induced phase advances of the circadian rhythms of systolic, diastolic and mean BP. When combined with HRT, amlodipine lowered the MESOR and reduced the amplitude of systolic BP without any phase change. In conclusion, amlodipine is effective in reducing BP in postmenopausal women. The maintenance of a normal circadian BP pattern is also influenced by supplementation with 17beta-estradiol. The 8-week treatment with amlodipine alone and in combination with HRT is not associated with a marked influence on bone metabolism. |
