Single-pill Fixed-dose Combination Research Articles

An Expert Opinion on the Role of the Rosuvastatin/Amlodipine Single Pill Fixed Dose Combination in Cardiovascular Prevention.

Current cardiovascular disease prevention strategies are based on the management of cardiovascular risk as a continuum, redefining the therapeutic goals for each individual based on the estimated global risk profile. Given the frequent clustering of the principal cardiovascular risk factors, such as hypertension, diabetes and dyslipidaemia, in the same individual, patients are required to take multiple drugs to achieve therapeutic targets. The adoption of single pill fixed dose combinations may contribute to achieve better control of blood pressure and cholesterol compared to the separate administration of the individual drugs, mostly due to better adherence related to therapeutic simplicities. This paper reports the outcomes of an Expert multidisciplinary Roundtable. In particular, the rational and potential clinical use of the single pill fixed dose combination "Rosuvastatin-Amlodipine" for the management of concomitant hypertension/hypercholesterolemia in different clinical fields are discussed. This Expert Opinion also illustrates the importance of an early and effective management of total cardiovascular risk, highlights the substantial benefits of combining blood pressure and lipid-lowering treatments in a single-pill fixed dose combination and attempts to identify and overcome the barriers to the implementation in clinical practice of the fixed dose combinations with dual targets. This Expert Panel identifies and proposes the categories of patients who may benefit the most from this fixed dose combination.

Long-term clinical outcomes of oral antidiabetic drugs as fixed-dose combinations: A nationwide retrospective cohort study.

To compare treatment patterns and clinical outcomes of single-pill fixed-dose combination (FDC) and two-pill combination (TPC) therapies using real-world data. We conducted a nationwide retrospective cohort study using South Korea's healthcare database (2002-2015). We identified two cohorts of incident patients with type 2 diabetes who initiated FDC or TPC therapy within 4 months of their first prescription for metformin or sulphonylurea. We examined persistence and adherence patterns and the clinical outcome of a composite endpoint of death or hospitalization for acute myocardial infarction, heart failure or stroke and compared the differences in treatment patterns and clinical outcomes using Cox models. Of 5143 and 10 973 patients who initiated FDC and TPC therapy, respectively, we identified 5143 patient pairs after propensity score matching. The FDC group exhibited greater median time to treatment discontinuation (163 vs. 146 days), and proportion of days covered at 12 months (mean 0.60 vs. 0.57, P < .0001) and at 24 months (0.53 vs. 0.51, P=.014) than the TPC group. The FDC group, compared with the TPC group, had reduced risks of the composite clinical outcome (hazard ratio 0.86, 95% confidence intervals 0.77-0.97) and hospitalization for stroke (0.80, 0.67-0.96). FDC therapy may provide favourable cardiovascular benefits, especially reducing the risk of hospitalization for stroke, and has better medication adherence among patients with type 2 diabetes.

Hypokalaemia associated with hydrochlorothiazide used in the treatment of hypertension in NHANES 1999-2018.

Hydrochlorothiazide is the most common thiazide diuretic used for hypertension in the US. Yet, hypokalaemia is a well-recognised adverse effect. To evaluate the prevalence and factors associated with hypokalaemia (serum potassium < 3.5 mmol/L) among hydrochlorothiazide users, we included US adults aged ≥20 years in the 1999-2018 National Health and Nutrition Examination Survey. Participants were categorised according to the use of hydrochlorothiazide and other antihypertensive agents. Factors associated with hypokalaemia, including demographics and prescription patterns (monotherapy vs single-pill fixed-dose combination vs polytherapy) were studied using multivariable logistic regression. Hypokalaemia was present in 12.6% of the hydrochlorothiazide users, equivalent to ~2.0 million US adults. Women (adjusted OR, 2.22; 95% CI, 1.74-2.83), non-Hispanic blacks (adjusted OR, 1.65; 95% CI, 1.31-2.08), underweight (adjusted OR, 4.33; 95% CI, 1.34-13.95), and participants taking hydrochlorothiazide for five years or more (adjusted OR, 1.47; 95% CI, 1.06-2.04) had a higher risk of hypokalaemia. Compared to monotherapy, fixed-dose combination therapy (adjusted OR, 0.32; 95% CI, 0.21-0.48) was associated with the lowest risk. Among those taking potassium supplements, hypokalaemia was found in 27.2% of participants on monotherapy and 17.9% on polytherapy. The prevalence of hypokalaemia among hydrochlorothiazide users was considerable, even among participants who also took potassium supplements. Women, ethnic minorities, underweight, monotherapy, and participants with long-term therapy are more likely to have hypokalaemia. Regular monitoring of potassium and combination with potassium-sparing drugs are needed.

Single-pill fixed-dose drug combinations to reduce blood pressure: the right pill for the right patient.

Arterial hypertension is one of the major causes of cardiovascular morbidity and mortality worldwide. Effective and sustained reduction in blood pressure is essential to reduce individual cardiovascular risk. In daily clinical practice, single-pill fixed-dose combinations of different drug classes are important therapeutic resources that could improve both treatment adherence and cardiovascular risk management by targeting distinct pathophysiological mechanisms. The aim of this practical narrative review is to help physicians choosing the right single-pill fixed-dose combination for the right patient in the daily clinical practice, based on the individual clinical phenotype and cardiovascular risk profile.

Assessment of a strategy combining ambulatory blood pressure, adherence monitoring and a standardised triple therapy in resistant hypertension

Purpose Poor adherence to drug therapy and inadequate drug regimens are two frequent factors responsible for the poor blood pressure (BP) control observed in patients with apparent resistant hypertension. We evaluated the efficacy of an antihypertensive management strategy combining a standardised therapy with three long acting drugs and electronic monitoring of drug adherence in patients with apparent resistant hypertension. Materials and Methods In this multicentric observational study, adult patients with residual hypertension on 24 h ambulatory BP monitoring (ABMP) despite the use of three or more antihypertensive drugs could be included. Olmesartan/amlodipine (40/10 mg, single pill fixed-dose combination) and chlorthalidone (25 mg) were prescribed for 3 months in two separated electronic pills boxes (EPB). The primary outcome was 24 h ambulatory systolic BP (SBP) control at 3 months, defined as mean SBP <130 mmHg. Results We enrolled 48 patients (36.0% women) of whom 35 had complete EPB data. After 3 months, 52.1% of patients had 24 h SBP <130 mmHg. 24 h SBP decreased by respectively −9.1 ± 15.5 mmHg, −22.8 ± 30.6 mmHg and −27.7 ± 16.6 mmHg from the tertile with the lowest adherence to the tertile with the highest adherence to the single pill combination (p = 0.024). A similar trend was observed with tertiles of adherence to chlorthalidone. Adherence superior to 90% was associated with 24 h systolic and diastolic blood pressure control in multiple logistic regression analysis (odds ratio = 14.1 (95% confidence interval 1.1–173.3, p = 0.039). Conclusions A simplified standardised antihypertensive therapy combined with electronic monitoring of adherence normalises SBP in about half of patients with apparent resistant hypertension. Such combined management strategy enables identifying patients who need complementary investigations and those who rather need a long-term support of their adherence.

Prescribing Patterns of Antihypertensives for Treatment-Naïve Patients in South Korea: From Korean NHISS Claim Data.

Background Several factors influence the choice of antihypertensive drugs. To facilitate the rational use of drugs it is important to assess their prescription patterns over time. This study aims to evaluate doctors' prescribing patterns of antihypertensive drugs for drug-naïve patients in South Korea. Methods The claims data of the Korean National Health Insurance Research Database from 1 January 2011 to 31 December 2015 were analyzed. The data virtually cover the entire South Korean population. Antihypertensive drugs were further subdivided into angiotensin receptor blockers (ARBs), angiotensin-converting enzyme inhibitors (ACEis), calcium channel blockers (CCBs), beta-blockers (BBs), and thiazide diuretics. The prescription pattern of antihypertensive drugs and associated factors were assessed according to the patients' characteristics, including associated comorbidities. Results A total of 2,919,162 subjects had started taking antihypertension medications during the study period. ARB was the most frequently prescribed drug (51.6%) followed by CCB (45.0%), BB (18.5%), diuretics (17.0%), and ACEi (11.7%). Most patients were prescribed with monotherapy (66.7%) rather than combination therapy (33.3%), and CCB was the most frequently prescribed monotherapy drug (25.7%). For combination therapy, ARB + CCB was the most frequently prescribed combination, and the prescription frequency was found to be increasing. In patients prescribed with combination therapy, most had been prescribed single-pill fixed-dose combination. Conclusion We identified the physicians' prescription patterns of antihypertensive drugs for treatment-naïve patients. The findings of this study can lead to a rational, evidence-based, and cost-effective improvement of prescription patterns in newly diagnosed hypertensive patients.

European guidelines for the management of arterial hypertension 2018-what has changed?

In November 2017, the latest American guidelines for the management of arterial hypertension were published. With these guidelines lowering the threshold for hypertension to 130/80 mm Hg, the latest European guidelines were expected with excitement. This article gives an overview on the European Society of Cardiology (ESC) and European Society of Hypertension (ESH) 2018 guidelines for the management of arterial hypertension, thereby identifying the most relevant changes in comparison to previous guidelines. The latest 2018 ESC/ESH guidelines adhere to the previous definition of hypertension, in which ablood pressure of 140/90 mm Hg is considered as threshold for diagnosis. In contrast, there was achange in blood pressure treatment target from below 140/90 to between 120-129/70-79 mm Hg in patients < 65years if well tolerated. Among patients ≥ 65years, asystolic blood pressure between 130 and 139 mm Hg is recommended, whereas adiastolic blood pressure between 70 and 79 mm Hg should be targeted. Additionally the guidelines recommend the use of fixed dose combinations as first choice instead of monotherapy to improve adherence. Interventional treatment strategies should only be applied in carefully selected patients at experienced centers and are not recommended outside of clinical studies and registers. Furthermore, the chapters regarding initiation of blood pressure-lowering therapy and clinical evaluation as well as management of hypertension emergencies have been outlined. The latest European guidelines for the management of hypertension include several changes. One of the most important aspects is that-in contrast to the American guidelines-the threshold for diagnosis remains at 140/90 mm Hg, whereas treatment target range has been lowered by roughly 10 mm Hg and single pill fixed dose combinations are recommended.

Fixed-dose combination antihypertensive medications, adherence, and clinical outcomes: A population-based retrospective cohort study.

BackgroundThe majority of people with hypertension require more than one medication to achieve blood pressure control. Many patients are prescribed multipill antihypertensive regimens rather than single-pill fixed-dose combination (FDC) treatment. Although FDC use may improve medication adherence, the impact on patient outcomes is unclear. We compared clinical outcomes and medication adherence with FDC therapy versus multipill combination therapy in a real-world setting using linked clinical and administrative databases.Methods and findingsWe conducted a population-based retrospective cohort study of 13,350 individuals 66 years and older in Ontario, Canada with up to 5 years of follow-up. We included individuals who were newly initiated on one angiotensin-converting enzyme inhibitor (ACEI) or angiotensin II-receptor blocker (ARB) plus one thiazide diuretic. High-dimensional propensity score matching was used to compare individuals receiving FDC versus multipill therapy. The primary outcome was a composite of death or hospitalization for acute myocardial infarction (AMI), heart failure, or stroke. We conducted 2 analyses to examine the association between adherence and patient outcomes. First, we performed an on-treatment analysis to determine whether outcomes differed between groups while patients were on treatment, censoring patients when they first discontinued treatment, defined as not receiving medications within 150% of the previous days’ supply. Second, we conducted an intention-to-treat analysis that followed individuals allowing for breaks in treatment to quantify the difference in drug adherence between groups and assess its impact on clinical outcomes. As expected, there was no significant difference in the primary outcome between groups in the on-treatment analysis (HR 1.06, 95% CI 0.86–1.31, P = 0.60). In the intention-to-treat analysis, the proportion of total follow-up days covered with medications was significantly greater in the FDC group (70%; IQR 19–98) than in the multipill group (42%, IQR 11–91, P < 0.01), and the primary outcome was less frequent in FDC recipients (3.4 versus 3.9 events per 100 person-years; HR 0.89, 95% CI 0.81–0.97, P < 0.01). The main limitations of this study were the lack of data regarding cause of death and blood pressure measurements and the possibility of residual confounding.ConclusionsAmong older adults initiating combination antihypertensive treatment, FDC therapy was associated with a significantly lower risk of composite clinical outcomes, which may be related to better medication adherence.

Single-Pill Triple Fixed Dose Combination Therapy with Single Component Drug Monitoring in Treatment-Resistant Hypertension: A Pilot Study.

Single-pill fixed dose combination (FDC) therapies are widely used in the treatment of arterial hypertension. This pilot study aimed to evaluate the effects of a FDC therapy combined with therapeutic drug monitoring (TDM) on blood pressure (BP) in patients with treatment resistant hypertension. The study population included patients with suspected treatment-resistant hypertension during treatment with at least 3 antihypertensive drugs. We evaluated the effect of switching all patients to a regime including a single-pill triple FDC containing olmesartan, amlodipine and hydrochlorothiazide. Adherence was evaluated by measuring serum concentrations of amlodipine in a single-blinded fashion. We enrolled 13 patients (mean age 57.2±9.1 years, 8 males) with resistant hypertension (office systolic and diastolic BP 158.3±17.3 and 94.8±11.1 mmHg); mean use of antihypertensive drugs was 3.8±1.1. Medication intake of FDC was confirmed in all patients at 18 weeks. Systolic and diastolic office BP were significantly lower (-22.8 and -13.6 mmHg) after 18 weeks of treatment with triple FDC (135.5±20.1 and 81.2±6.3 mmHg, p<0.01, respectively); mean use of antihypertensive drugs was 3.8±0.9. In 9 patients with 24-h ambulatory BP monitoring (ABPM) both at baseline and after 18 weeks, 24-h mean arterial pressure decreased (-9.3 mmHg, p=0.055). Overall, 9 (69%) patients achieved BP control in office BP and 4 (31%) in 24-h ABPM. Our results support the use of single-pill triple FDC therapy in combination with TDM for the management of patients with suspected treatment-resistant hypertension and further testing in clinical studies.

Triple Combination Therapies Based on Olmesartan: A Personalized Therapeutic Approach to Improve Blood Pressure Control.

Recent epidemiological surveys have demonstrated that effective and sustained blood pressure (BP) control is achieved in a relatively small proportion of treated hypertensive patients. Indeed, treatment of hypertension represents a key strategy for preventing coronary artery disease, stroke, congestive heart failure and cardiovascular death. Several interventions have been proposed by international guidelines for ameliorating hypertension management and control, mostly including integrated and multi-dimensional pharmacological and non-pharmacological strategies. In particular, numerous evidence demonstrated that a more extensive use of combination therapy may represent a valid therapeutic option for treating hypertensive patients at different risk profile. This strategy has been definitely strengthened by the availability of single pill fixed-dose combinations. Among potential combination therapies, those based on the association of renin-angiotensin system antagonists, thiazide diuretics and calcium channel blockers are very effective in lowering BP levels and well tolerated. We will provide here an overview of clinical evidence supporting the use of triple combination therapy, with a focus on that based on olmesartan medoxomil, a thiazide diuretic (hydrochlorothiazide) and a calcium channel blocker (amlodipine besylate), which is available in multiple dosages. Finally, in view of the recognised importance of single-pill combination therapy for treating hypertension, we will examine the potential benefits of dual (fixed) combination therapy based on olmesartan medoxomil with either thiazide diuretic hydrochlorothiazide or calcium channel blocker amlodipine in terms of efficacy, safety and tolerability profile.

The effects of increasing calcium channel blocker dose vs. adding a diuretic to treatment regimens for patients with uncontrolled hypertension.

In patients with insufficient blood pressure (BP) control, despite using a combination regimen containing an angiotensin receptor blocker and a calcium channel blocker (CCB), whether a greater dose of CCB or adding a diuretic is more effective at lowering BP remains unclear. We conducted a multicenter randomized clinical trial to compare the efficacy of switching from the daily administration of a single-pill fixed-dose combination of irbesartan (100 mg) and amlodipine (5 mg) to irbesartan (100 mg) with an increased dose of amlodipine (10 mg) (HD group, n=62) or irbesartan (100 mg) and amlodipine (5 mg) with 1 mg of indapamide (D group, n=63) in patients with poorly controlled hypertension. BP measured at home was monitored by a physician using a telemonitoring system. Between the HD and D groups, no significant differences were observed in morning home BP changes (mean reduction of systolic/diastolic BP, 1.7/0.9 mmHg; 95% confidence intervals, -2.4 to 5.7/-1.4 to 3.2; P=0.19/0.37), achievement rate of target BP (45.2% vs. 42.9%, P=0.80), BP variability independent of the mean (P⩾0.74), other variability indices (P⩾0.55) and time to stabilization, which was calculated using a fitted analysis (13.1 days vs. 11.4 days, P=0.99). Although a significant increase in serum uric acid was observed in the D group (P<0.0001), neither clinically relevant abnormal laboratory test results nor critical BP changes were observed throughout the trial period. Both antihypertensive drug combination strategies were effective treatment options. Further investigation is required to determine the appropriate use of both therapies based on the various pathologies associated with hypertension.

Current Situation of Medication Adherence in Hypertension.

Despite increased awareness, poor adherence to treatments for chronic diseases remains a global problem. Adherence issues are common in patients taking antihypertensive therapy and associated with increased risks of coronary and cerebrovascular events. Whilst there has been a gradual trend toward improved control of hypertension, the number of patients with blood pressure values above goal has remained constant. This has both personal and economic consequences. Medication adherence is a multifaceted issue and consists of three components: initiation, implementation, and persistence. A combination of methods is recommended to measure adherence, with electronic monitoring and drug measurement being the most accurate. Pill burden, resulting from free combinations of blood pressure lowering treatments, makes the daily routine of medication taking complex, which can be a barrier to optimal adherence. Single-pill fixed-dose combinations simplify the habit of medication taking and improve medication adherence. Re-packing of medication is also being utilized as a method of improving adherence. This paper presents the outcomes of discussions by a European group of experts on the current situation of medication adherence in hypertension.

Blood Pressure Control: A Marathon or a Sprint?

This symposium discussed several recent initiatives used around the world to improve the management of hypertensive patients and achieve better blood pressure (BP) control. The key objectives of the symposium were to review the current position with regards to BP control in Europe, to discuss the initiatives used in Italy, France, and Canada to improve hypertension management and their outcomes, and to assess how single-pill fixed-dose combinations of antihypertensive drugs have improved adherence. Some of the key barriers to BP control were discussed and measures to overcome these presented, so that further improvements in hypertension management can be achieved going forward. Prof Anthony Heagerty opened the meeting by discussing the key causes of suboptimal BP control and the results of the SPRINT study. Prof Massimo Volpe presented the initiative to achieve 70% BP control and assessed its success to date in Italy. Prof Jean-Jacques Mourad discussed the results of the PAssAGE 2014 study and French League Against Hypertension Survey (FLAHS) in 2015, following the initiative to achieve 70% BP control in France by the end of 2015. Prof Raj Padwal presented the Canadian hypertension Education Program (CHEP) and the improvements in the management of hypertensive patients in Canada. Finally, Dr Julian Segura bought the meeting to a close by discussing how fixed-dose combinations have improved adherence in clinical practice.

Fixed-dose combination therapy of nebivolol and valsartan for the treatment of hypertension

ABSTRACTRecent large clinical trials have refuted earlier suggestions from the Joint National Committee 8 committee that less aggressive targets for blood pressure control were all that could be justified in most hypertensive patients. It now does appear that in fact “lower is better,” with blood pressure targets < 120/80 mm Hg appropriate for many hypertensive patients. Two drug combinations are often indicated as initial therapy if a 20/10 mm Hg or greater blood pressure reduction is necessary to reach target. Combinations consisting of β-blockers and renin-angiotensin-aldosterone system inhibitors have previously been deemed “less effective,” based on partially overlapping mechanisms of action and limited clinical trial evidence. Nebivolol is a vasodilating β1-selective blocker and β3- adrenoceptor agonist; β3-adrenoceptor activation increases nitric oxide concentrations and thus explains the vasodilatory effect. A recent 8-week randomized trial (N=4,161) in individuals with stage 1-2 hypertension demonstrated that single-pill fixed dose combinations (FDC) of nebivolol and valsartan, an angiotensin II subtype 1 receptor blocker, were more effective in reducing blood pressure than the corresponding monotherapies, with comparable tolerability. In addition, an ABPM-biomarkers substudy from that trial (n=805) demonstrated that the FDC prevented a valsartan-induced increase in plasma renin activity, and that the nebivolol/valsartan 20/320 mg/day dose reduced plasma aldosterone concentration significantly more than valsartan 320 mg/day. This article will describe the properties of nebivolol that make it unique and separate it from other β-blockers, and will further support the pharmacological advantages of this particular combination.

Efficacy and Safety of a Single-Pill Fixed-Dose Combination of Azilsartan and Amlodipine.

BackgroundGuidelines for the management of hypertension recommend the use of drugs with different mechanisms of action in antihypertensive regimens that include single-pill fixed-dose combinations of medications. There is some controversy regarding which single-pill fixed-dose combinations of angiotensin II type 1 receptor blockers (ARBs) and calcium channel blockers (CCBs) are effective at reducing blood pressure (BP).MethodsForty hypertensive patients who were receiving a single-pill fixed-dose combination of valsartan 80 mg/day and amlodipine 5 mg/day or irbesartan 100 mg/day and amlodipine 5 mg/day were enrolled. They were randomly divided into two treatment groups, a group that changed to a single-pill fixed-dose combination of azilsartan 20 mg/day and amlodipine 5 mg/day (changeover group) and a group that continued to receive valsartan 80 mg/day and amlodipine 5 mg/day or irbesartan 100 mg/day and amlodipine 5 mg/day (control group), and treated for 16 weeks.ResultsThere were no significant differences in systolic blood pressure (SBP), diastolic blood pressure (DBP) or pulse rate (PR) at 16 weeks between the control and changeover groups. In addition, there were no significant changes in biochemical parameters throughout the study period in both groups.ConclusionThe ability of a single-pill fixed-dose combination of azilsartan and amlodipine to reduce BP may be comparable to that of a combination of valsartan and amlodipine or irbesartan and amlodipine.

Management of Blood Pressure Control: At the Cutting Edge

Prof Williams opened the symposium by discussing the current state of blood pressure (BP) control in Europe and the key barriers to improving BP control rates. Prof Weiss presented the ‘Low BP in Vienna’ initiative that has been initiated in Austria in order to improve BP control. Prof Mourad discussed the ongoing campaign to improve BP control rates in France, and Prof Volpe presented a case study of an elderly patient with hypertension and chronic kidney disease (CKD). Prof Parati concluded the symposium by commenting on the improvements in technology with respect to BP control. The meeting objectives were to review the current achievement of BP goals in Europe since 2008; to evaluate the 70% BP goal initiatives in France and Italy; to use practical examples to assess the use of single-pill fixed-dose combinations (FDCs); and to assess the impact of technological advances on BP control.

Comparative effect of fixed-dose combination tablets of candesartan cilexetil/amlodipine versus olmesartan medoxomil/azelnidipine on laboratory parameters in patients with hypertension: a retrospective cohort study

We conducted a retrospective cohort study to evaluate and compare the long-term effects of two single-pill fixed-dose combinations (FDCs), candesartan/amlodipine and olmesartan/azelnidipine, on laboratory parameters in patients in routine clinical practice. We identified an equal number of new users (n = 182) of a candesartan/amlodipine (8/5 mg/day) FDC tablet (CAN/AML users) and a propensity-score matched cohort (n = 182) receiving an olmesartan/azelnidipine (20/16 mg/day) FDC tablet (OLM/AZ users). Generalized estimating equations were used to estimate and compare the effects of the drugs on serum levels of creatinine, estimated glomerular filtration rate (eGFR), blood urea nitrogen (BUN), uric acid, sodium, potassium, aspartate aminotransferase, and alanine aminotransferase levels up to 12 months after the start of study drug administration. There was a significant increase of serum creatinine level and a significant decrease of eGFR from the baseline period to during the exposure period in both CAN/AML and OLM/AZ users, and a significant increase of BUN level in CAN/AML users. However, there were no significant differences in the mean changes of laboratory parameters between CAN/AML and OLM/AZ users. Our findings suggested that the effects of CAN/AML and OLM/AZ on laboratory parameters, including an unfavorable effect on renal function, were similar at least during 1 year of administration.

Efficacy and safety of two single-pill fixed-dose combinations of angiotensin II receptor blockers/calcium channel blockers in hypertensive patients (EXAMINER study)

Background: There is some controversy regarding which single-pill fixed-dose combinations of angiotensin II type 1 receptor blockers (ARBs) and calcium channel blockers (CCBs) are effective at reducing blood pressure (BP). Methods: Sixty hypertensive patients who received a single-pill fixed-dose combination of valsartan 80 mg/day and amlodipine 5 mg/day were enrolled (UMIN Registration 000013460). They were randomly divided into two treatment groups [single-pill fixed-dose combination therapy with valsartan 80 mg/day and amlodipine 5 mg/day (Val/Am group), or irbesartan 100 mg/day and amlodipine 5 mg/day (Irb/Am group)] and treated for 16 weeks. If the patient did not reach the target office BP at 8 weeks, they received double doses of amlodipine (10 mg/day). Results: In the Irb/Am group, systolic BP (SBP) and diastolic BP (DBP) were significantly decreased at 16 weeks. There were no significant changes in SBP or DBP in the Val/Am group. In the Irb/Am group, serum uric acid (UA) was significantly decreased at 8 weeks and patients who had hyperuricemia showed significantly decreased serum UA at 16 weeks. In addition, the levels of triglycerides (TG) were significantly decreased at 16 weeks in the Irb/Am group. Conclusion: A single-pill fixed-dose combination therapy with irbesartan 100 mg/day and amlodipine 5 mg/day was superior to the combination of valsartan 80 mg/day and amlodipine 5 mg/day with respect to significant decreases in BP, serum UA and TG in patients with hypertension.

Achieving Goal Blood Pressure.

Both monotherapy and combination therapy options are appropriate for antihypertensive therapy according to the 2013 European Society of Hypertension (ESH)/European Society of Cardiology (ESC) guidelines. Most patients require more than one agent to achieve blood pressure (BP) control, and adding a second agent is more effective than doubling the dose of existing therapy. The addition of a third agent may be required to achieve adequate BP reductions in some patients. Single-pill fixed-dose combinations (FDCs) allow multiple-drug regimens to be delivered without any negative impact on patient compliance or persistence with therapy. FDCs also have documented beneficial clinical effects and use of FDCs containing two or three agents is recommended by the 2013 ESH/ESC guidelines.

Hypertension Care: It’s Time to Act

The satellite symposium was held in two separate sessions – the first a traditional symposium format, and the second as an interactive panel discussion in which the faculty answered questions from the delegates. The symposium objectives included consideration of the impact of suboptimal blood pressure (BP) control on the high levels of cardiovascular (CV) events in Europe; evaluation of the importance of patient adherence in improving management of BP; consideration of the management of treatment-resistant patients; discussion of a new initiative to drive improved management of hypertension; and how angiotensin receptor blocker (ARB)-based treatments and single-pill combinations may be used to treat hypertensive patients. Professor Burnier discussed the difficulties associated with achieving good BP control in the primary care setting and highlighted the utility of single-pill fixed-dose combinations (FDCs) for improving adherence and BP normalisation. Professor Ruilope discussed the clinical work-up and management of patients with treatment-resistant hypertension, while Professors Schmieder and Weiss outlined some initiatives taking place that aim to improve BP control rates. Finally, Professor Volpe described an ARB-based treatment platform which shows how patients can be effectively treated with single-pill combination therapy.
