Despite the benefits of blood pressure (BP) reduction, approximately 70% of hypertensive adults worldwide are uncontrolled [Hajjar I et al. \u003Cem\u003EJAMA\u003C\/em\u003E 2003]. In the US, 50% of patients who receive antihypertensive therapy do not achieve BP goals [Hajjar I et al. \u003Cem\u003EJAMA\u003C\/em\u003E 2003].

Pharmacological treatment typically begins with monotherapy, followed by sequential monotherapy or by combination therapy in patients who do not reach BP goals. More than half of hypertensive patients will require combination therapy to lower their BP below 140\/90 mm Hg. Ideally, antihypertensive agents that are used in combination therapy should be selected to maximize potential synergistic effects on BP, maintain acceptable tolerability, and minimize adverse effects.\u003C\/p\u003E\n         \u003Cp id=\u0022p-4\u0022\u003EAccording to the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC 7), most patients with hypertension will require two or more antihypertensive agents [Chobanian AV et al. \u003Cem\u003EJAMA\u003C\/em\u003E 2003]. A second drug from a different class should be added when a single drug in adequate doses is insufficient to achieve BP goals (\u003Ca id=\u0022xref-fig-1-1\u0022 class=\u0022xref-fig\u0022 href=\u0022#F1\u0022\u003EFigure 1\u003C\/a\u003E). When BP is more than 20\/10 mm Hg above goal, initial treatment with combination therapy should be considered. Combination therapy is also recommended by other major guidelines on hypertension treatment. The Consensus Statement of the Hypertension in African Americans Working Group of the International Society on Hypertension in Blacks (ISHIB) recommends first-line combination antihypertensive therapy for patients with a systolic BP that is 15 mm Hg or more above target or a diastolic BP that 10 mm Hg or more above target [Douglas JG et al. \u003Cem\u003EArch Intern Med\u003C\/em\u003E 2003].\u003C\/p\u003E\n         \u003Cdiv id=\u0022F1\u0022 class=\u0022fig pos-float  odd\u0022\u003E\u003Cdiv class=\u0022highwire-figure\u0022\u003E\u003Cdiv class=\u0022fig-inline-img-wrapper\u0022\u003E\u003Cdiv class=\u0022fig-inline-img\u0022\u003E\u003Ca href=\u0022http:\/\/d282kpwvnogo5m.cloudfront.net\/content\/spmdc\/10\/7\/6\/F1.large.jpg?width=800\u0026amp;height=600\u0026amp;carousel=1\u0022 title=\u0022JNC 7 Algorithm for the Treatment of Hypertension.\u0022 class=\u0022fragment-images colorbox-load\u0022 rel=\u0022gallery-fragment-images-2034068089\u0022 data-figure-caption=\u0022JNC 7 Algorithm for the Treatment of Hypertension.\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003E\u003Cimg class=\u0022fragment-image\u0022 alt=\u0022Figure 1.\u0022 src=\u0022http:\/\/d282kpwvnogo5m.cloudfront.net\/content\/spmdc\/10\/7\/6\/F1.medium.gif\u0022\/\u003E\u003C\/a\u003E\u003C\/div\u003E\u003C\/div\u003E\u003Cul class=\u0022highwire-figure-links inline\u0022\u003E\u003Cli class=\u00220 first\u0022\u003E\u003Ca href=\u0022http:\/\/d282kpwvnogo5m.cloudfront.net\/content\/spmdc\/10\/7\/6\/F1.large.jpg?download=true\u0022 class=\u0022highwire-figure-link highwire-figure-link-download\u0022 title=\u0022Download Figure 1.\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003EDownload figure\u003C\/a\u003E\u003C\/li\u003E\u003Cli class=\u00221\u0022\u003E\u003Ca href=\u0022http:\/\/d282kpwvnogo5m.cloudfront.net\/content\/spmdc\/10\/7\/6\/F1.large.jpg\u0022 class=\u0022highwire-figure-link highwire-figure-link-newtab\u0022 target=\u0022_blank\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003EOpen in new tab\u003C\/a\u003E\u003C\/li\u003E\u003Cli class=\u00222 last\u0022\u003E\u003Ca href=\u0022\/highwire\/powerpoint\/11493\u0022 class=\u0022highwire-figure-link highwire-figure-link-ppt\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003EDownload powerpoint\u003C\/a\u003E\u003C\/li\u003E\u003C\/ul\u003E\u003C\/div\u003E\u003Cdiv class=\u0022fig-caption attrib\u0022\u003E\u003Cspan class=\u0022fig-label\u0022\u003EFigure 1.\u003C\/span\u003E \n               \u003Cp id=\u0022p-5\u0022 class=\u0022first-child\u0022\u003EJNC 7 Algorithm for the Treatment of Hypertension.\u003C\/p\u003E\n            \u003Cq class=\u0022attrib\u0022 id=\u0022attrib-1\u0022\u003EReproduced with permission from the National Heart, Lung, and Blood Institute.\u003C\/q\u003E\u003Cdiv class=\u0022sb-div caption-clear\u0022\u003E\u003C\/div\u003E\u003C\/div\u003E\u003C\/div\u003E\n      \u003C\/div\u003E\u003Cdiv class=\u0022section\u0022 id=\u0022sec-2\u0022\u003E\n         \u003Ch2 class=\u0022\u0022\u003EEmerging Role of Combination Antihypertensive Therapy\u003C\/h2\u003E\n         \u003Cp id=\u0022p-6\u0022\u003ECombination therapy is one of the most important tools in the management of uncontrolled BP. When appropriately selected, fixed-dose combination therapies can significantly increase patient compliance, reduce side effects, and improve BP control. In a meta-analysis of 354 randomized, double-blind, placebo-controlled trials that enrolled a total of 56,000 patients with uncontrolled BP, Law and colleagues demonstrated important features of combination antihypertensive therapy [Law MR et al. \u003Cem\u003EBMJ\u003C\/em\u003E 2003]. Patients were treated with thiazide-type diuretics, \u03b2-blockers, angiotensin-converting enzyme (ACE) inhibitors, angiotensin II receptor blockers (ARBs), and\/or calcium channel blockers, given alone or as part of combination therapy.\u003C\/p\u003E\n         \u003Cp id=\u0022p-7\u0022\u003EWhen given alone at standard doses, all five classes of antihypertensive medications yielded similar reductions in systolic (mean, 9.1 mm Hg) and diastolic (mean, 5.5 mm Hg) BP. At half-standard doses, the antihypertensive medications still provided pronounced reductions in systolic and diastolic BP (7.1 mm Hg and 4.1 mm Hg, respectively). When given in combination, the BP-lowering effects of different drugs classes were additive, but adverse events were not. Moreover, with the exception of ACE inhibitor-associated cough, all treatment-related adverse events appeared to be dose-related.\u003C\/p\u003E\n         \u003Cp id=\u0022p-8\u0022\u003EThe study authors concluded that the use of combination low-dose antihypertensive therapy significantly improved treated efficacy while reducing the risk of adverse events. For a hypothetical patient aged 60 to 69 years with a baseline BP of 150\/90 mm Hg, combination therapy with 2 or 3 low-dose antihypertensive agents would be preferable to treatment with 1 or 2 agents at standard dose. In this example, combination low-dose therapy could reduce BP by approximately 20\/11 mm Hg, thereby reducing the lifetime risk of stroke by 63% and the risk of ischemic heart events by 46% [Law MR et al. \u003Cem\u003EBMJ\u003C\/em\u003E 2003].\u003C\/p\u003E\n      \u003C\/div\u003E\u003Cdiv class=\u0022section\u0022 id=\u0022sec-3\u0022\u003E\n         \u003Ch2 class=\u0022\u0022\u003EARB-Based Combination Antihypertensive Therapy\u003C\/h2\u003E\n         \u003Cp id=\u0022p-9\u0022\u003EIn patients with hypertension, ARBs appear to have many benefits beyond BP reduction. ARBs reduce the risk of CV and cerebrovascular events. In patients with comorbid type 2 diabetes, ARBs slow the progression of renal damage and delay the onset of diabetic nephropathy. ARBs have also been shown to improve outcomes in patients with heart failure and following an acute MI. Given this range of potential benefits, there is considerable interest in incorporating ARBs into combination antihypertensive regimens.\u003C\/p\u003E\n         \u003Cp id=\u0022p-10\u0022\u003ESeveral recent trials have focused on evaluating the efficacy and safety of ARB-based combination regimens. The INCLUSIVE trial enrolled 1005 patients whose hypertension was uncontrolled despite treatment with a single antihypertensive agent. In this difficult-to-treat patient population, treatment with the fixed-dose combination of irbesartan and hydrochlorothiazide (HCTZ) reduced systolic and diastolic BP by 20.5 mm Hg and 10.4 mm Hg, respectively (p\u0026lt;0.001). After 18 weeks of therapy, 77% of patients reached the systolic BP goal of \u0026lt;140 mm Hg (\u0026lt;130 mm Hg in patients with diabetes), and 83% of patients reached the diastolic BP goal of \u0026lt;90 mm Hg (\u0026lt;80 mm Hg in those with diabetes) [Neutel JM et al. \u003Cem\u003EJ Clin Hypertens\u003C\/em\u003E 2005].\u003C\/p\u003E\n         \u003Cp id=\u0022p-11\u0022\u003EThe RAPiHD trial demonstrated the early therapeutic benefits of first-line combination irbesartan\/HCTZ therapy in patients with severe hypertension. In this patient population, nearly half (47%) of patients medicated with this combination reached the diastolic BP goal of \u0026lt;90 mm Hg after 5 weeks of treatment. The mean reduction in systolic and diastolic BP following 5 weeks of treatment with irbesartan\/HCTZ was 30.8 mm Hg and 24.0 mm Hg, respectively.

Each VAL\/HCTZ combination was associated with significantly greater reductions in BP compared with placebo or with either agent given as monotherapy (p\u0026lt;0.001 for all). The mean reduction in mean sitting diastolic and systolic BP with VAL\/HCTZ 320\/25 mg compared with VAL\/HCTZ 160\/12.5 mg (p\u0026lt;0.002). The combination regimen was also well tolerated, with fewer episodes of hypokalemia than HCTZ alone [Pool JL et al. \u003Cem\u003EClin Ther\u003C\/em\u003E 2007]. In the VELOCITY trial, adverse event rates with first-line valsartan\/HCTZ combination therapy were similar to those with valsartan monotherapy [Jamerson K et al. \u003Cem\u003EJ Clin Hypertens\u003C\/em\u003E 2007].\u003C\/p\u003E\n      \u003C\/div\u003E\u003Cdiv class=\u0022section\u0022 id=\u0022sec-4\u0022\u003E\n         \u003Ch2 class=\u0022\u0022\u003EAdditional Benefits of Combination Therapy\u003C\/h2\u003E\n         \u003Cp id=\u0022p-15\u0022\u003EPatients with more complex antihypertensive regimens, including a higher pill burden, are less likely to adhere to therapy.

Most patients will require combination antihypertension therapy to achieve treatment targets. The initial or earlier use of combination therapy may allow patients to achieve the clinical benefits of BP reduction more quickly, with fewer adverse events and a greater likelihood of adherence, compared with single-agent treatment.\u003C\/p\u003E\n      \u003C\/div\u003E\u003Cul class=\u0022copyright-statement\u0022\u003E\u003Cli class=\u0022fn\u0022 id=\u0022copyright-statement-1\u0022\u003E\u00a9 2010 MD Conference Express\u003C\/li\u003E\u003C\/ul\u003E\u003Cspan class=\u0022highwire-journal-article-marker-end\u0022\u003E\u003C\/span\u003E\u003C\/div\u003E\u003Cspan id=\u0022related-urls\u0022\u003E\u003C\/span\u003E\u003C\/div\u003E\u003Ca href=\u0022http:\/\/mdc.sagepub.com\/content\/10\/7\/6.abstract\u0022 class=\u0022hw-link hw-link-article-abstract\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003EView Summary\u003C\/a\u003E\u003C\/div\u003E  \u003C\/div\u003E\n\n  \n  \u003C\/div\u003E\n\u003C\/div\u003E\n  \u003C\/div\u003E\n\u003C\/div\u003E\n\u003C\/div\u003E\u003Cscript type=\u0022text\/javascript\u0022 src=\u0022http:\/\/mdc.sagepub.com\/sites\/all\/modules\/highwire\/highwire\/plugins\/highwire_markup_process\/js\/highwire_figures.js?nzmpk5\u0022\u003E\u003C\/script\u003E\n\u003Cscript type=\u0022text\/javascript\u0022 src=\u0022http:\/\/mdc.sagepub.com\/sites\/all\/modules\/highwire\/highwire\/plugins\/highwire_markup_process\/js\/highwire_openurl.js?nzmpk5\u0022\u003E\u003C\/script\u003E\n\u003C\/body\u003E\u003C\/html\u003E"}
