[The assessment of renal function during the therapy of arterial hypertension with azilsartan medoxomil in patients with obesity or overweight and concomitant metabolic disorders].

AIM: To assess the influence of the therapy of arterial hypertension with azilsartan medoxomil on the renal function in overweight or obese patients with concomitant metabolic disorders. MATERIALS AND METHODS: An international multicenter observational nonintervention prospective study included 1945 patients, taking azilsartan medoxomil in accordance with approved prescribing information. The observation period reached 6 months. RESULTS: In patients with an initial glomerular filtration rate (GFR)60 ml/min/1.73 m2 or 60 ml/min/1.73 m2 mean change in systolic blood pressure after 6 months of therapy reached -32.511.1 and -30.413.6 mmHg, correspondingly, while the change in diastolic blood pressure was -13.78.8 and -14.29.4 mmHg, respectively. No decrease in renal function was observed. Moreover, in patients with an initial GFR60 ml/min/1.73 m2 GFR increased significantly (p0.001). CONCLUSION: Azilsartan medoxomil, prescribed as monotherapy or in free combinations, provided an effective control of blood pressure in patients with arterial hypertension with both normal or moderately reduced and initially significantly reduced renal function. High efficacy and acceptability of the drug was associated with a beneficial effect on renal function, which allows to consider azilsartan medoxomil as the drug of choice for the treatment of hypertension in patients with concomitant metabolic disorders.

[Choice of an Optimal Blocker of the Renin-Angiotensin-Aldosterone System in Patients With Concomitant Arterial Hypertension and Chronic Obstructive Pulmonary Disease].

OBJECTIVE: to compare hypotensive and pleiotropic effects of angiotensin II receptor blocker (ARB) azilsartan medoxomil (AM) and angiotensin converting enzyme inhibitor (ACEI) fosinopril in patients with concomitant arterial hypertension (AH) and chronic obstructive pulmonary disease (COPD). MATERIALS AND METHODS: We included in this open study 49 patients with concomitant stage I-II AH and COPD. Initially all patients received hydrochlorothiazide (12.5 mg/day) and various ACEI but target blood pressure levels were not achieved, and these ACEI were withdrawn. By method of closed envelopes, the patients were divided into 2 groups. Patients of group 1 were given ARB АМ, of group 2 - ACEI fosinopril. Methods of investigation were repetitive 24­hour ambulatory blood pressure monitoring (ABPM), spirometry, measurement of mean pulmonary artery pressure (mPAP), study of endothelial function by instrumental and laboratory methods. RESULTS: After 4 weeks of treatment with AM target BP level (.

AT1 receptor blocker azilsartan medoxomil normalizes plasma miR-146a and miR-342-3p in a murine heart failure model.

Our study measured circulating microRNA (miRNA) levels in the plasma of calsequestrin (CSQ)-tg mouse, a severe heart failure model, and evaluated whether treatment with angiotensin II type 1 receptor blocker, azilsartan medoxomil (AZL-M) influenced their levels using miRNA array analysis. MiR-146a, miR-149, miR-150, and miR-342-3p were reproducibly reduced in the plasma of CSQ-tg mice. Among them, miR-146a and miR-342-3p were significantly restored by AZL-M, which were associated with improvement of survival rate and reduction of congestion. These results suggest that miRNA, especially miR-146a and miR-342-3p, could be used as potential biomarkers for evaluating the efficacy of anti-heart failure drugs.

[Antihypertensive Efficacy of Fixed Combination Azilsartan Medoxomil / Chlorthalidone in Patients With Uncontrolled Arterial Hypertension].

AIM: To study effects of a fixed azilsartan medoxomil/chlorthalidone combination (Edarbi Clo) on clinical, ambulatory and central blood pressure (BP) in patients with uncontrolled arterial hypertension (AH)). MATERIALS AND METHODS: Patients (n=25) with uncontrolled AH were given fixed azilsartan medoxomil/chlorthalidone combination (40 / 12.5 mg / day) for 4 weeks. After 4 weeks, in patients who did not achieve target BP levels the dose was increased up to 40 / 25 mg / day. Duration of the study was 12 weeks. RESULTS: After 12 weeks of treatment 88 % of patients achieved target clinical BP (.

Single-dose pharmacokinetics and safety of azilsartan medoxomil in children and adolescents with hypertension as compared to healthy adults.

PURPOSE: This open-label, multicenter, single-dose study characterized the pharmacokinetics and short-term safety of azilsartan medoxomil (AZL-M) in hypertensive pediatric subjects (12-16 years [cohort 1a; n = 9]; 6-11 years [cohort 2; n = 8]; 4-5 years [cohort 3; n = 3]). METHODS: Model-based simulations were performed to guide dosing, especially in 1-5-year olds, who were difficult to enroll. AZL-M was dosed according to body weight (20-60-mg tablet, cohorts 1a and 2; 0.66 mg/kg granule suspension, cohort 3). In cohort 1, gender-matched healthy adults (cohort 1b; n = 9) received AZL-M 80 mg. RESULTS: Exposure to AZL (active moiety of AZL-M), measured by dose-/body weight-normalized C max and AUC0-∞, was ∼15-30 % lower in pediatric subjects versus adults. In simulations, exposure with 0.66 mg/kg AZL-M in pediatric subjects weighing 8-25 kg approximated to AZL-M 40 mg (typical starting dose) in adults. The simulations suggest that 25-50-kg subjects require half the adult dose (10-40 mg), whereas 50-100-kg subjects can use the same dosing as adults. Adverse events were mild in intensity, apart from one moderate event (migraine). CONCLUSIONS: This dosing strategy should be safe in pediatric patients, as AZL exposure would not exceed that seen in adults with the highest approved AZL-M dose (80 mg).

[Hronotherapy Aspects of Efficiency Azilsartan Medoxomil in Combination Therapy in Patients With Hypertension and Metabolic Syndrome].

OBJECTIVE: Determination of the effectiveness and safety of different dosing regimens during the day (in the morning or at bedtime) combination therapy including azilsartan medoxomil in patients with essential hypertension and metabolic syndrome (MS). DESIGN AND METHODS: The study included 60 patients with uncontrolled hypertension and MS (age median - 59 (54-65) years). Patients were randomized in two groups: group 1 (n=30) received azilsartan medoxomil 40 mg/day, and indapamide retard 1,5 mg/day in the morning; group 2 (n=30)- azilsartan medoxomoil 40 mg at bedtime and indapamide retard 1,5 mg in the morning. All patients at baseline, and after 4 and 12weeks assessed levels of office blood pressure (BP), heart rate (HR); at baseline and after 12 weeks was conducted ambulatory BPmonitoring (ABPM). Evaluated the main indicators of circadian blood pressure profile, as well as the central aortic pressure (CAP) and the rigidity of the vascular wall: systolic, diastolic, and mean arterial pressure in the aorta, aortic augmentation index, pulse wave velocity in the aorta, the augmentation index. Study results were processed using the program Statistica 6.1 by methods nonparametric statistics. RESULTS: Regardless of the regimen used azilsartan destination as part of combination therapy after 4 weeks showed a significant (p<0.05) reduction in SBP and DBP. After 12 weeks of observation target blood pressure was recorded 27 (90%) patients of group 1 and 29 (96.7%)- group2. As a result of ABPM after 12 weeks of treatment in both groups showed a statistically significant (p<0.05) improvement in all parameters investigated. However, positive changes such indicators as an index time of hypertension in the day and night hours, SBP, DBP, and BP variability during the night, the morning rise of systolic as well as the speed of morning rise in SBP and DBP were more pronounced in the appointment azilsartan medoxomil at bedtime compared to morning reception. The use of both treatment regimens provided significant (p<0.05) increase frequency registration profile dippear and reduction - non-dipper. Importantly, irrespective of the time of taking the drugs in both groups occurred significant (p <0.05), and a comparable improvement in rigidity and CAP vascular wall. CONCLUSION: When combined with essential hypertension and MS azilsartana use of combination drug therapy provided achievement of the target values of blood pressure in the majority of patients, a significant improvement in the main indicators of ABPM, CAP, and the rigidity of the vascular wall, as well as the normalization of daily profile of blood pressure in the majority of patients, regardless of dosing regimen during the day. However, the combination of indapamide retard morning - azilsartan medoxomil at bedtime accompanied by a significantly greater positive changes most ABPM parameters, especially at night.

[Azilsartan Medoxomil Capabilities in Arterial Hypertension and Obesity].

Arterial hypertension (AH) is one of the most common cardiovascular disease. Angiotensin II (AT II), the hormone of renin-angiotensin-aldosterone system, realizes its negative effects through AT 1 receptors - application point of angiotensin receptor blockers (ARB). Due to different dissociation AT 1 receptors properties some ARBs are more effective than others. Multiply multicenter randomized and observational studies approve the effectiveness and safety of azilsartan medoxomil in patients with AH 1-2 grade. Several preclinical studies have shown the additional properties of azilsartan, including increase of insulin sensitivity, cardio- and nephron protection in obesity. In our clinical case we showed the positive influence of azilsartan medoxomil on clinic and ambulatory blood pressure, 24-hour aortic stiffness parameters, longitudinal left ventricular strain in patient with AH and obesity.

Efficacy and safety of azilsartan medoxomil in the treatment of hypertension: a systematic review and meta-analysis.

Background: Angiotensin II receptor blockers (ARBs) are utilized for the management of hypertension and diabetes. Previous meta-analyses suggested that azilsartan medoxomil (AZL-M) improved blood pressure (BP) reduction, but there were no safety findings or suggestions for patients with hypertension or diabetes. Methods: We performed an efficacy and safety meta-analysis of randomized controlled trials (RCTs) evaluating AZL-M therapy for reducing BP in patients with hypertension. Patients with hypertension complicated by diabetes were analyzed. The relevant literature was searched in English and Chinese databases for RCTs involving AZL-M in hypertension. Efficacy variables included the change from baseline in the 24-h mean systolic/diastolic BP measured by ambulatory BP monitoring, the change from baseline in clinic systolic/diastolic BP, and responder rates. Safety variables included total adverse events (AEs), serious AEs, AEs leading to discontinuation, and AEs related to the study drug. The raw data from the included studies were utilized to calculate the odds ratio (OR) for dichotomous data and the mean difference (MD) for continuous data, accompanied by 95% confidence intervals (CIs). Statistical analysis was performed using R software. Results: A total of 11 RCTs met the inclusion criteria, representing 7,608 patients, 5 of whom had diabetes. Pooled analysis suggested a reduction in BP among patients randomized to 40 mg of AZL-M vs. control therapy [24-h ambulatory blood pressure monitoring (ABPM) mean systolic blood pressure (SBP) (MD: -2.85 mmHg), clinic SBP (MD: -3.48 mmHg), and clinic diastolic blood pressure (DBP) (MD: -1.96 mmHg)] and for 80 mg of AZL-M vs. control therapy [24-h ABPM mean SBP (MD: -3.59 mmHg), 24-h ABPM mean DBP (MD: -2.62 mmHg), clinic SBP (MD: -4.42 mmHg), clinic DBP (MD: -3.09 mmHg), and responder rate (OR: 1.46)]. There was no difference in the reduction of risks, except for dizziness (OR: 1.56) in the 80-mg AZL-M group or urinary tract infection (OR: 1.82) in the 40-mg AZL-M group. Analysis of patients with diabetes revealed that AZL-M can provide superior management, while safety and tolerability were similar to those of control therapy. Conclusions: AZL-M appears to reduce BP to a greater extent than dose-control therapy and does not increase the risk of adverse events in patients with hypertension and diabetes compared with placebo.

Exploring the Effectiveness and Safety of Azilsartan-Medoxomil/Chlorthalidone Versus Olmesartan-Medoxomil/Hydrochlorothiazide in Hypertensive Patients: A Meta-Analysis.

This study aims to assess the effectiveness and safety of azilsartan-medoxomil/chlorthalidone (AZI-M/CT) compared to olmesartan-medoxomil/hydrochlorothiazide (OLM/HCTZ) in patients with hypertension. Systematic searches were conducted on PubMed, Google Scholar, and ClinicalTrials.gov, starting from their establishment until March 15, 2023. The purpose of these searches was to locate original reports that compare the effectiveness of AZI-M/CT and OLM/HCTZ in treating hypertension. Data on various characteristics at the beginning and end of the studies were gathered. The analyses were carried out using Review Manager 5.4.1 (The Nordic Cochrane Center, The Cochrane Collaboration, 2014, Odense, Denmark) and STATA 16.0 software (Stata Corp. LP, College Station, TX, USA). Risk ratios (RRs) and weighted mean differences (WMDs) with 95% confidence intervals (CIs) were calculated as part of the study. A total of 3,146 individuals from four separate investigations were included in the study, with 1,931 individuals receiving AZI-M/CT and 1,215 individuals receiving OLM/HCTZ. The combined analysis revealed that the average diastolic blood pressure (DBP) was significantly lower in the AZI-M/CT group compared to the OLM/HCTZ group (WMD -2.64 [-2.78, -2.51]; P = 0.00001; I2 = 1%). However, there were no significant differences in mean systolic blood pressure (SBP; WMD -2.95 [-6.64, 0.73]; P = 0). Furthermore, the AZI-M/CT group had a notably higher incidence of major adverse events (RR 1.58 [1.20, 2.08]; P = 0.001; I2 = 11%) and any treatment-emergent adverse events (RR 1.11 [1.03, 1.20]; P = 0.007; I2 = 51%). However, there was no significant difference in the mortality risk between the two groups (RR 0.74 [0.14, 3.91]; P = 0.72; I2 = 0%). Based on the results of our meta-analysis, AZI-M/CT is more effective than OLM/HCTZ at reducing blood pressure in elderly hypertensive patients. However, because of the small sample size, favorable results must be carefully reevaluated, and more studies are needed.

Central Composite Design Implemented Azilsartan Medoxomil Loaded Nanoemulsion to Improve Its Aqueous Solubility and Intestinal Permeability: In Vitro and Ex Vivo Evaluation.

The present research attempted to design and develop a nanoemulsion formulation of azilsartan medoxomil to improve its aqueous solubility and intestinal permeability. Based on the solubility profile, ethyl oleate, tween 80, and Transcutol P were selected as the oil phase, surfactant, and co-surfactant, respectively. Central composite design (CCD) suggested an optimized azilsartan medoxomil- nanoemulsion formulation (optimized AZL-NE formulation) with 1.25% oil, 15.73% Smix, and 90 s ultrasonication time; it was found to have the droplet size, percentage transmittance, and % cumulative drug release (%CDR) of 71.5 nm, 93.46 ± 1.13%, and 90.14 ± 0.94%, respectively. Furthermore, it exhibited a 0.141 polydispersity index, 34.05 mV zeta potential, a 1.413 ± 0.03 refractive index, 6.68 ± 0.22 pH, 28.17 ± 0.52 cps viscosity, and a 96.98 ± 0.94% percentage drug content. Transmission electron microscopy (TEM) assessed the nano-sized spherical shape, and a differential scanning calorimeter (DSC) assessed the solubilization of the drug in the optimized formulation. The %CDR was 1.71 times higher and the % cumulative drug permeation was 2.1 times higher for the optimized AZL-NE formulation than for the drug suspension through an intestinal segment of a rat, which was also supported by confocal laser scanning microscopy (CLSM) studies. Thus, the nanoemulsion formulation of azilsartan medoxomil ensured the enhancement of the drug availability in the body.

An international multicenter observational non-interventional prospective study of the efficacy of azilsartan medoxomil in overweight or obese patients with arterial hypertension (CONSTANT).

BACKGROUND: Control of arterial hypertension in obese or overweight patients is complicated since obesity directly contributes to increased blood pressure, requiring new, highly effective antihypertensive drugs. This study evaluates the efficacy of azilsartan medoxomil in real clinical practice. METHODS: An international multicenter observational non-interventional prospective study of azilsartan medoxomil was conducted in 64 clinical centers in the Russian Federation and 5 centers in the Republic of Kazakhstan. This study included 1945 obese or overweight patients with arterial hypertension. Azilsartan medoxomil was prescribed in accordance with the approved instruction for use. The decision to prescribe the drug, dose adjustment and monitoring target BP achievement belonged to the attending physicians according to their routine clinical practice. The observation period took about 6 months. RESULTS: The average duration of taking the medicine was 26.1 ± 4 weeks. By the fourth visit, the use of azilsartan medoxomil either in a monotherapy regimen or in free combinations resulted in a pronounced decrease in systolic and diastolic blood pressure by 30.5 ± 13.4 and 14 ± 9.4 mmHg, respectively (p < .001 compared to baseline value). A positive response to therapy was observed in 92.6% of cases (95% CI: 91.3-93.7%). Target blood pressure was achieved by 86.4% of cases (95% CI: 84.8-87.9%). During the study period 43 adverse events were recorded, the most common of which were arterial hypotension and dizziness. CONCLUSIONS: Over the study time of 1945 patients, significant changes in blood pressure levels over time were noted, and a high frequency of response to the azilsartan therapy was observed. Adverse events related to the study drug were of mild or moderate intensity and did not require discontinuation of therapy. Thus, azilsartan medoxomil demonstrated a good safety profile and provided effective blood pressure control for overweight or obese patients with hypertension in real clinical practice.

Single-pill Combination Therapy of Azilsartan Medoxomil/Chlorthalidone for Treatment of Hypertension: A Systematic Review.

PURPOSE: The goal of this study was to review recent clinical studies of azilsartan medoxomil (AZL-M) and chlorthalidone (CLD), a combined angiotensin receptor blocker and thiazide-like diuretic, and its role in recently published guidelines. This review explores the role of AZL-M/CLD in treating patients with hypertension. METHODS: A systematic review of literature published from 1990 to 2018 was performed by using the following key words: Edarbyclor, azilsartan, chlorthalidone, pharmacokinetic, and hypertension. Available English-language data from reviews, abstracts, presentations, and clinical trials regarding the use of AZL-M/CLD therapy specifically detailing effects of lowering blood pressure (BP) and outcomes on cardiovascular disease in humans and rats were reviewed. FINDINGS: One study compared a single-pill combination of AZL-M/CLD with co-administration of AZL-M and hydrochlorothiazide and found a greater reduction in clinic systolic BP with AZL-M/CLD (-35.1 mm Hg vs -29.5 mm Hg) than for AZL-M and hydrochlorothiazide. Another study of 153 patients with chronic kidney disease who received AZL-M/CLD or other single-pill combination agents found that AZL-M/CLD was more effective in lowering BP, achieving superior adherence. According to new guidelines, an increase in the prevalence of resistant hypertension can occur as a result of trying to lower target BP. IMPLICATIONS: A powerful and effective medication that can increase patient compliance is essential to reduce the incidence of resistant hypertension. AZL-M/CLD is a powerful and safe antihypertensive medication that has been thoroughly studied in patients with hypertension.

Efficacy and Safety of Azilsartan Medoxomil and Telmisartan in Hypertensive Patients: A Randomized, Assessor-Blinded Study.

BACKGROUND: Few studies have compared the safety and efficacy of azilsartan medoxomil (AZL-M) and telmisartan in hypertensive patients, especially using ambulatory blood pressure monitoring (ABPM). OBJECTIVE: The objective of this study was to compare the efficacy and safety profile of AZL-M and telmisartan in hypertensive patients using ABPM and clinic blood pressure (BP) monitoring. MATERIALS AND METHODS: This prospective, randomized, open-label, blinded endpoint, parallel-arm study included 700 patients, aged 18-70 years, with clinic and 24-h mean ambulatory systolic BP (SBP) of 150-180 mmHg and 130-170 mmHg, respectively. They were randomized equally into two groups: Group A received AZL-M 40 mg and Group T received telmisartan 40 mg; the dose was force titrated to 80 mg after 2 weeks if the response rate was not achieved. BP (clinical and ambulatory) was measured after 12 weeks and compared with baseline measurements. RESULTS: AZL-M significantly reduced the 24-h mean ambulatory SBP (Group A: 112.74 ± 7.58 mmHg; Group T: 113.96 ± 8.52 mmHg; P < 0.0001) and diastolic BP (Group A: 71.39 ± 5.89 mmHg; Group T: 67.29 ± 6.79 mmHg; P < 0.0001) compared with telmisartan at week 12. The clinic SBP significantly decreased in Group A at weeks 4 (-30.69± -0.33 mmHg) and 12 (-39.69± -1.09 mmHg) (for both, P = 0.0001). Dose titration was done in 99 and 128 patients from Group A and Group T, respectively (P = 0.012). Headache was the most common adverse drug reaction (Group A: 21; Group T: 27) and fatigue the least. CONCLUSION: This study found that AZL-M has greater antihypertensive efficacy than telmisartan, with comparable side effects. In addition, ABPM was shown to be a feasible method for such studies.

Azilsartan medoxomil.

Azilsartan is used for treatment of the high blood pressure (hypertension). Reducing high blood pressure enables avoid strokes, heart attacks and problems of kidneys. Azilsartan comes under the name angiotensin receptor blocker (ARBs) as a class of drugs. It acts by relaxing blood vessels to make it easier for blood to flow. Azilsartan Medoxomil's a comprehensive profile containing the description, formulae, Elemental Analysis, Uses and application. Furthermore, methods and schemes are outlined for the preparation of the drug substance. The physical properties of the medication include constant of ionization, solubility, X-ray powder diffraction pattern, differential scanning calorimetry, thermal conduct and spectroscopic studies are investigated. The methods employed in bulk medicines and/or in pharmaceutical formulations to analyze the drug substance include spectrophotometric, electrochemical and the chromatographic methods. Other studies on this drug substance include drug stability, Pharmaceutical Applications, Mechanism of Action, Pharmacodynamics, and a Dosing Information are reviewed. At the end of this profile, there are more than sixty references were listed.

Strategies for stabilizing formulation and QbD assisted development of robust stability indicating method of azilsartan medoxomil/chlorthalidone.

Reasons for formulation instability were investigated either encountered during production or analytical processes of azilsartan medoxomil (AZM)/chlorthalidone hydrochloride (CLT) tablets. Through the identification of the most feasible degradation pathways, several strategies were proposed to enhance the stability of AZM/CLT formulation. Furthermore, a robust HPLC-UV method was developed and validated for the determination of AZM, CLT in the presence of their possible degradation products. For chromatographic method development, typical quality by design (QbD) approach was implemented. In order to optimize fourteen chromatographic responses, we have used a central composite design with four factors (pH, temperature, flow rate, and acetonitrile %). However, the developed method provides a design space, but optimum parameters were Inertsil C8 column (150 x 4.6 mm, 5 µm), mobile phase composed of 0.025 M phosphate buffer pH 2.7 and acetonitrile (52.5: 47.5%), with flow rate of 1.5 mL.min-1 and detection wavelength 225 nm at 33 °C. The method was then validated according to ICH guidelines and applied to quantitate AZM and CLT in the pharmaceutical formulation. To the best of our knowledge, this manuscript is the first attempt to discuss such instability issues, to propose strategies that enhance the stability of AZM/CLT tablet formulation, to develop robust stability-indicating method taking into consideration the realistic degradation products in addition to minor ones.

A randomized trial of the efficacy and safety of azilsartan medoxomil combined with chlorthalidone.

INTRODUCTION: We measured the effects of azilsartan medoxomil co-administered with chlorthalidone 25 mg in stage 2 hypertension. METHODS: Azilsartan medoxomil 40 or 80 mg plus chlorthalidone were compared with placebo plus chlorthalidone once daily in a randomized, double-blind, 6-week trial. The primary endpoint was change from baseline in 24-hour mean systolic blood pressure by ambulatory blood pressure monitoring. RESULTS: Patients ( N=551; mean age 59 years; 51.7% men) were randomly assigned to placebo plus chlorthalidone ( n=184), azilsartan medoxomil 40 mg plus chlorthalidone ( n=185), or azilsartan medoxomil 80 mg plus chlorthalidone ( n=182). Baseline systolic blood pressures were similar among groups. After 6 weeks, least squares mean (standard error) reductions with azilsartan medoxomil 40 mg and 80 mg plus chlorthalidone were similar in magnitude (-31.7 (1.0) and -31.3 (1.0) mmHg, respectively), but greater than chlorthalidone alone (-15.9 (1.0) mmHg). Hypotension and serum creatinine elevations were more frequent with azilsartan medoxomil plus chlorthalidone than chlorthalidone alone (reversed with drug discontinuation). Notably, plasma potassium reduction of 0.43 meq/L with chlorthalidone was attenuated to 0.13 and 0.05 meq/L by azilsartan medoxomil 40 mg and 80 mg, respectively. CONCLUSION: Azilsartan medoxomil 40 mg or 80 mg plus chlorthalidone 25 mg was significantly more efficacious than chlorthalidone alone in reducing blood pressure and was well tolerated.

Azilsartan and Chlorthalidone-new Powerful Fixed dose Antihypertensive Combination.

Arterial hypertension is a disease that still affects a major part of the population worldwide, and leads to fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions. From the CDC statistical analysis, as regarding to United States, 1 of every 3 adults has high blood pressure, and οnly about half (54%) of them have it under control. Furthermore, all that leads to a nation cost about $46 billion each year. Efforts to find new ways to regulate arterial hypertension are therefore imperative. In our days, a lot of references have been made to the use of a new therapeutic combination, that of azilsartan - an innovative ARB, in combination with chlorthalidone. Ιn fact, it is a combination now prescribed in a number of countries. A significant number of trials shows both azilsartan vs popular antihypertensive drugs, as well as chlorthalidone vs chlorothiazide, to present a better antihypertensive effect. This effect is even greater when the two substances are combined. In this article, we will try to present the latest findings concerning the efficacy, safety and clinical utility of this combination, as well as its adverse events, in comparison with other widely used therapeutic options.

Efficacy and safety of azilsartan medoxomil, an angiotensin receptor blocker, in Korean patients with essential hypertension.

BACKGROUND: This was a phase 3, randomized, double-blind, placebo-controlled study. METHODS: Adult Korean patients with essential hypertension and a baseline mean sitting clinic systolic blood pressure (scSBP) ≥150 and ≤180 mmHg were randomized to 6-week treatment with placebo (n = 65), azilsartan medoxomil (AZL-M) 40 mg (n = 132), or AZL-M 80 mg (n = 131). The primary endpoint was the change from baseline to week 6 in trough scSBP. RESULTS: The least-squares mean (standard error) change from baseline in trough scSBP in the placebo, AZL-M 40-mg, and 80-mg groups at week 6 were - 8.8 (2.00), - 22.1 (1.41), and - 23.7 (1.40) mmHg, respectively (p < 0.001 for AZL-M 40 and 80 mg vs placebo). No clinically meaningful heterogeneity in efficacy was observed between subgroups (age, sex, diabetes status) and the overall population. Treatments were well tolerated and adverse events were similar between groups. CONCLUSIONS: Results of this study confirm a positive benefit-risk profile of AZL-M for essential hypertension in Korean adults. TRIAL REGISTRATION: Clinicaltrial.gov; identifier number: NCT02203916.

Single-Center Evaluation of the Pharmacokinetics and Safety of the Angiotensin II Receptor Antagonist Azilsartan Medoxomil in Mild to Moderate Hepatic Impairment.

Azilsartan medoxomil (AZL-M) is a potent angiotensin II receptor blocker that decreases blood pressure in a dose-dependent manner. It is a prodrug that is not detected in blood after its oral administration because of its rapid hydrolysis to the active moiety, azilsartan (AZL). AZL undergoes further metabolism to the major metabolite, M-II, and minor metabolites. The objective of this study was to determine the effect of mild to moderate hepatic impairment on the pharmacokinetics of AZL and its major metabolite. This was a single-center, open-label, phase 1 parallel-group study that examined the single-dose (day 1) and multiple-dose (days 4-8) - 40 mg - pharmacokinetics of AZL and M-II in 16 subjects with mild and moderate hepatic impairment by Child-Pugh classification (n = 8 per group) and subjects (n = 16) matched based on age, sex, race, weight, and smoking status. Mild or moderate hepatic impairment did not cause clinically meaningful increases in exposure to AZL and M-II. Mild or moderate hepatic impairment had no clinically meaningful effect on the plasma protein binding of AZL and M-II. Single and multiple doses of AZL-M 40 mg were well tolerated in all subject groups. Based on the pharmacokinetic and tolerability findings, no dose adjustment of AZL-M is required for subjects with mild and moderate hepatic impairment.

Azilsartan as a Potent Antihypertensive Drug with Possible Pleiotropic Cardiometabolic Effects: A Review Study.

BACKGROUND: Hypertension related cardiovascular (CV) complications could be amplified by the presence of metabolic co-morbidities. Azilsartan medoxomil (AZL-M) is the eighth approved member of angiotensin II receptor blockers (ARBs), a drug class of high priority in the management of hypertensive subjects with diabetes mellitus type II (DMII). METHODS: Under this prism, we performed a systematic review of the literature for all relevant articles in order to evaluate the efficacy, safety, and possible clinical role of AZL-M in hypertensive diabetic patients. RESULTS: AZL-M was found to be more effective in terms of reducing indices of blood pressure over alternative ARBs or angiotensin-converting enzyme (ACE) inhibitors with minimal side effects. Preclinical studies have established pleiotropic effects for AZL-M beyond its primary antihypertensive role through differential gene expression, up-regulation of membrane receptors and favorable effect on selective intracellular biochemical and pro-atherosclerotic pathways. CONCLUSION: Indirect but accumulating evidence from recent literature supports the efficacy and safety of AZL-M among diabetic patients. However, no clinical data exist to date that evince a beneficial role of AZL-M in patients with metabolic disorders on top of its antihypertensive effect. Further clinical studies are warranted to assess the pleiotropic cardiometabolic benefits of AZL-M that are derived from preclinical research.
