indapamide--perindopril-drug-combination and Essential-Hypertension

More than 50 % of hypertensive patients have lipid disorders, and one-third of hypertensive patients have impaired glucose metabolism. Owing to the high prevalence of metabolic risk factors and/or comorbidities, antihypertensives with favorable or neutral metabolic effects are preferred. Based on the available evidence, diuretics and β-blockers are heterogeneous regarding their metabolic effects.. The aim of ACES (Antihypertensive Combinations' Long Term Efficacy Comparing Study) was to compare the efficacy and metabolic effects of a carvedilol/indapamide free combination, a fixed-dose combination of perindopril/amlodipine, and a fixed combination of perindopril/indapamide in everyday practice.. This study was a 6-month, multi-center, prospective, observational, non-interventional, open-label clinical study. The data of 9124 outpatients (4898 female, 4226 male; mean age 61.7 ± 11.7 years) with mild, moderate, or severe essential (primary) hypertension with one or more metabolic risk factors were subjected to statistical analysis. At visits one (day 1), three (month 3), and four (month 6), the following metabolic parameters were monitored: fasting blood glucose, glycosylated hemoglobin, estimated glomerular filtration rate, total cholesterol, high-density lipoprotein-cholesterol, low-density lipoprotein-cholesterol, triglycerides, and serum potassium, sodium, creatinine, and uric acid levels. A total of 3888 patients took perindopril/amlodipine, while 2992 took perindopril/indapamide, and 2244 took a combination of carvedilol/indapamide. Statistical analysis was carried out using the one-paired t test and the Chi square test; the two-sided level of significance was set at 0.05.. The observed changes in the main metabolic parameters were favorable and similar in all therapeutic groups: fasting blood glucose decreased by 5.5-5.5-5.5 %, total cholesterol by 9.0-10.2-9.9 %, and triglycerides by 12.7-15.4-13.8 % (respectively in perindopril/amlodipine, perindopril/indapamide and carvedilol/indapamide groups).. Based on our findings, we conclude that the metabolic profile of indapamide is very similar to the metabolically neutral and well-documented metabolic profiles of the calcium-channel blocker amlodipine and the vasodilator β-blocker carvedilol and that all the combinations studied had similar beneficial effects on the main metabolic parameters. The favorable changes of metabolic parameters are because of the discontinuation of active substances (e.g., conventional thiazides, second-generation β-blockers) used in the previous therapy, which were associated with unfavorable metabolic effects, and to the increase in the ratio of administered lipid-lowering drugs and oral antidiabetic drugs.

The relationship between blood pressure (BP) and cerebral blood flow (CBF) is not fully understood. This study evaluated the impact of a perindopril arginine/indapamide (Pa/I) single-pill combination (SPC) on CBF in middle-aged patients.. A total of 22 treatment-naïve patients with essential hypertension and at least one hypertension-mediated organ damage and 41 healthy controls were enrolled. At baseline, all participants underwent brain magnetic resonance imaging (MRI); patients with hypertension underwent an additional MRI at end of follow-up. Arterial spin labeling (ASL) was used to calculate CBF in the frontal lobe cortical plate. Patients with hypertension received once-daily Pa/I 5 mg/1.25 mg SPC, which could be increased to Pa/I 10 mg/2.5 mg at 2 weeks if necessary. Patients with hypertension underwent 24-h ambulatory BP monitoring (ABPM) at baseline and end of follow-up.. Mean baseline BP values were 146.2/93.1 and 119.1/76.1 mmHg in the hypertension and control groups, respectively. Patients with hypertension had significantly (p < 0.001) lower CBF in the cortical plate of both left (36.2 ± 8.3 vs. 45.3 ± 3.5 ml/100 g/min) and right (37.9 ± 7.9 vs. 45.8 ± 3.2 ml/100 g/min) frontal lobes compared to normotensive controls. At the end of follow-up, there was a statistically significant (p < 0.001) increase in CBF in the cortical plate of both left (from 36.2 ± 8.3 to 47.5 ± 9.8 ml/100 g/min) and right frontal lobes (from 37.9 ± 7.9 to 47.4 ± 10.1 ml/100 g/min) compared to baseline. No significant difference was found between end of follow-up CBF levels in frontal lobes of patients with hypertension and those of healthy controls at baseline. Office BP decreased by 24.2/15.5 mmHg and 24-h ABPM from 145.5/95.3 to 120.8/79.3 mmHg.. In middle-aged, treatment-naïve patients with hypertension, Pa/I SPC was associated with increased CBF in the cortical plate of the frontal lobes, which achieved levels of normotensive controls. The increase in CBF had no clear association with observed BP changes.. ISRCTN67799751.
