A comparison of the efficacy and safety of irbesartan/HCTZ combination therapy with irbesartan and HCTZ monotherapy in the treatment of moderate hypertension

This prospective, double-blind, parallel-group study randomized patients with moderate hypertension (seated systolic blood pressure (SeSBP) 160-179 mm Hg when seated diastolic blood pressure (SeDBP) <110 mm Hg; or SeDBP 100-109 mm Hg when SeSBP <180 mm Hg) 3:1:1 to treatment with irbesartan 300 mg/hydrochlorothiazide (HCTZ) 25 mg combination therapy (n=328), irbesartan 300 mg monotherapy (n=106) or HCTZ monotherapy 25 mg (n=104). Treatment was initiated at half dose, with forced titration to full dose after two weeks followed by ten further weeks' treatment. The primary efficacy variable was the mean reduction in SeSBP from baseline to week 8. Baseline characteristics were similar between groups, with mean baseline blood pressure approximately 162/98 mm Hg; the mean age was 55 years. At week 8 there was a reduction in SeSBP of 27.1 mm Hg with irbesartan/HCTZ, compared with 22.1 mm Hg with irbesartan monotherapy (P=0.0016) and 15.7 mm Hg with HCTZ (P<0.0001). Both the rate of decline and the total degree of decline achieved were greatest with irbesartan/HCTZ and least with HCTZ. A significantly greater percentage of patients reached a treatment goal of SeSBP <140 mm Hg and SeDBP <90 mm Hg by week 8 with irbesartan/HCTZ (53.4%), compared with irbesartan (40.6%; P=0.0254) and HCTZ (20.2%; P<0.0001) alone. Treatment was well tolerated in all three-treatment groups with a slight increase in adverse events in the combination therapy group. In conclusion, irbesartan/HCTZ (300/25 mg) is well tolerated and achieves rapid and sustained reductions in both systolic blood pressure and diastolic blood pressure in patients with moderate hypertension.     

Assessing duration of antihypertensive effects with whole-day blood pressure monitoring

The whole-day blood pressure response to once-daily and twice-daily administration of a combination of captopril and hydrochlorothiazide was measured in a study of elderly patients (aged 59 to 78 years) with mild to moderate hypertension. Whole-day automated ambulatory blood pressure profiles were obtained at baseline, after 8 weeks of therapy with a combination of 25 mg of captopril and 15 mg of hydrochlorothiazide twice daily, and again after 8 weeks of once-daily therapy with 50 mg of captopril and 25 mg of hydrochlorothiazide. Average systolic and diastolic whole-day blood pressures significantly decreased from baseline during both twice-daily treatment (mean +/- SEM change, 18 [+/- 3]/10 [+/- 2] mm Hg) and once-daily treatment (11 [+/- 2]/9 [+/- 1] mm Hg). While the decrease in systolic blood pressure during once-daily therapy was less than that during twice-daily therapy for the group as a whole, 16 of 19 patients achieved normal systolic (less than 140 mm Hg) and diastolic (less than 90 mm Hg) blood pressures throughout the day during the once-daily regimen. During once-daily therapy, the blood pressure reductions were sustained throughout the 24-hour period, and were not attenuated during the final 2 to 4 hours before the next dose. A subgroup of 5 patients were identified who appeared unresponsive to both twice-daily and once-daily antihypertensive treatment. Despite hypertensive office-measured blood pressures at entry to the study, 4 of these 5 patients actually had normotensive whole-day blood pressure averages at baseline (mean, 131 [+/- 7]/81 [+/- 4] mm Hg). Thus, whole-day ambulatory blood pressure monitoring is a valuable tool for testing treatment responses. It demonstrated that once-daily treatment with low doses of captopril and hydrochlorothiazide was as effective as twice-daily administration in decreasing diastolic pressures throughout the day, but was slightly less effective in decreasing systolic pressures. Additionally, the monitoring identified apparently normotensive patients in whom treatment may not be indicated.     

Safety and Tolerability of Fixed-Dose Irbesartan/Hydrochlorothiazide for Rapid Control of Severe Hypertension

This prospective, double-blind, multicenter trial compared the safety and tolerability of irbesartan/hydrochlorothiazide (HCTZ) fixed-dose combination therapy with irbesartan monotherapy in patients with severe hypertension (seated diastolic blood pressure (SeDBP) ≥110 mm Hg, mean BP 172/113 mm Hg at baseline). Patients were randomized 2:1 to 7 weeks' irbesartan/HCTZ 150/12.5 mg to 300/25 mg (n = 468) or irbesartan 150 mg to 300 mg (n = 227). The incidence of treatment-related adverse events (AEs) was similar with combination and monotherapy (11.3% and 10.1%), and most AEs were mild-to-moderate. The combined incidence of prespecified AEs was lower with irbesartan/HCTZ than with irbesartan (8.8% vs. 11.5%). There were no treatment-related serious AEs or deaths. At week 5, more patients achieved SeDBP < 90 mm Hg compared to irbesartan (47% vs. 33%; P = 0.0005). Despite more rapid and aggressive BP lowering, initial fixed-dose irbesartan/HCTZ demonstrated a comparable AE profile to irbesartan monotherapy in patients with severe hypertension.     

The antihypertensive efficacy of the combination of irbesartan and hydrochlorothiazide assessed by 24-hour ambulatory blood pressure monitoring. Irbesartan Multicenter Study Group

In a multicenter, double-blind, randomized trial, 178 patients with ambulatory diastolic blood pressure (BP) > or =85 mm Hg and seated diastolic BP (SeDBP) 95-110 mm Hg received either once-daily irbesartan 75 mg/hydrochlorothiazide (HCTZ) 12.5 mg, irbesartan 150 mg/HCTZ 12.5 mg, or placebo for 8 weeks to assess reductions in 24-hour ambulatory BP and office BP. Safety and tolerability of all treatment regimens were also evaluated. BP results and therapeutic response (trough SeDBP normalized to <90 mm Hg) were expressed as change from baseline to Week 8. Mean reductions in 24-hour ambulatory BP and office seated BP for irbesartan/HCTZ combinations were significantly greater compared with placebo (all, p<0.01). More patients were normalized with irbesartan/HCTZ (65%-69%) than placebo (24%, p<0.01). The frequency of adverse events was similar in all groups. Irbesartan/HCTZ given once-daily appears to be a well-tolerated, safe, and effective antihypertensive treatment.     

A candesartan cilexetil/hydrochlorothiazide combination tablet provides effective blood pressure control in hypertensive patients inadequately controlled on monotherapy

In this double-blind, placebo-controlled, randomised, parallel-group study, a combination tablet of candesartan cilexetil/hydrochlorothiazide (HCTZ), 16/12.5 mg once daily, reduced sitting diastolic blood pressure (DBP) significantly more (p = 0.037) than candesartan cilexetil/placebo, 16 mg once daily, in patients with mild to moderate primary hypertension (n = 328) who had not reached target blood pressure with candesartan cilexetil, 16 mg once daily. At the end of the 8-week double-blind treatment period, the adjusted mean reductions in sitting DBP, 24 h post dose, were 7.5 mm Hg in the candesartan cilexetil/HCTZ treatment group and 5.5 mm Hg in the candesartan cilexetil/placebo treatment group, corresponding to an adjusted mean difference between treatments of 2.0 mm Hg in favour of candesartan cilexetil/HCTZ (95% CI 0.1-3.8 mm Hg, p = 0.037). The adjusted mean reductions in sitting systolic blood pressure, 24 h post dose, were 12.0 mm Hg and 7.5 mm Hg, respectively, corresponding to an adjusted mean difference between treatments of 4.5 mm Hg (95% CI 1.1-8.0, p = 0.01). Consistent with the placebo-like tolerability of candesartan cilexetil reported in other studies, both treatments were very well tolerated, with a similar pattern and low frequency of adverse events in both treatment groups.     

Initial Combination Therapy With Irbesartan/Hydrochlorothiazide for Hypertension: An Analysis of the Relationship Between Baseline Blood Pressure and the Need for Combination Therapy

Hypertension treatment guidelines recommend initiating 2-drug therapy whenever blood pressure (BP) is ≥20 mm Hg systolic or ≥10 mm Hg diastolic above goal. This post hoc pooled analysis of 2 multicenter, randomized, double-blind, active-controlled forced-titration studies in 1235 patients with moderate and severe hypertension examined how baseline BP levels relate to the need for combination therapy by comparing the antihypertensive efficacy and tolerability of once-daily fixed-dose irbesartan/hydrochlorothiazide (HCTZ) 300/25 mg compared with irbesartan 300-mg or HCTZ 25-mg monotherapies. In study 1, patients with severe hypertension (seated diastolic BP [SeDBP] ≥110 mm Hg) were treated for 7 weeks with irbesartan or irbesartan/HCTZ combination therapy, with forced-titration after week 1. In study 2, patients with moderate hypertension (seated systolic BP [SeSBP] 160–180 mm Hg or SeDBP 100–110 mm Hg) were treated for 12 weeks with irbesartan/HCTZ, irbesartan monotherapy, or HCTZ monotherapy, with forced-titration after week 2. The relationship between baseline BP and the likelihood of achieving BP goals (SeSBP <140 mm Hg or SeDBP <90 mm Hg; SeSBP <130 mm Hg or SeDBP <80 mm Hg) as well as the antihypertensive response was evaluated at week 7/8. The need for combination therapy increased with increasing baseline BP and lower BP goals across the range of BP levels studied, with a comparable adverse effect profile to monotherapy. These results suggest that the likelihood of achieving an early BP goal for a given BP severity should be considered when choosing initial combination therapy vs monotherapy.     

Efficacy and safety of irbesartan/HCTZ combination therapy as initial treatment for rapid control of severe hypertension

Severe hypertension is difficult to control. This prospective, randomized, double-blind, active-controlled, multicenter trial compared efficacy and safety of once-daily irbesartan/hydrochlorothiazide (HCTZ) combination therapy with irbesartan monotherapy in severe hypertension. Patients who were untreated or uncontrolled on monotherapy (seated diastolic blood pressure [BP] ≥110 mm Hg) received fixed-dose irbesartan 150 mg/HCTZ 12.5 mg combination therapy for 7 weeks, force-titrated to irbesartan 300 mg/HCTZ 25 mg at week 1 (n=468); or irbesartan 150 mg monotherapy, force-titrated to 300 mg at week 1 (n=269). Significantly more patients on combination therapy achieved seated diastolic BP <90 mm Hg at week 5 (primary end point) compared with monotherapy recipients (47.2% vs 33.2%; P= .0005). Likewise, significantly more patients attained goals per the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC 7) (<140/90 mm Hg) at week 5 (34.6% vs 19.2%, respectively; P< .0001), while the mean difference between combination and monotherapy in seated diastolic BP and seated systolic BP was 4.7 mm Hg and 9.7 mm Hg ( P< .0001). Greater and more rapid BP reduction with irbesartan/HCTZ was achieved without additional side effects.     

The efficacy and safety of low- and high-dose fixed combinations of irbesartan/hydrochlorothiazide in patients with uncontrolled systolic blood pressure on monotherapy: the INCLUSIVE trial

This multicenter, prospective, open-label, single-arm study determined the efficacy and safety of irbesartan/hydrochlorothiazide (HCTZ) fixed combinations in patients (n=1005), aged 18 years and older, with uncontrolled systolic blood pressure (SBP) of 140-159 mm Hg (130-159 mm Hg for type 2 diabetes mellitus) after at least 4 weeks of antihypertensive monotherapy. Treatment was sequential: placebo (4-5 weeks), HCTZ 12.5 mg (2 weeks), irbesartan/HCTZ 150/12.5 mg (8 weeks), and irbesartan/HCTZ 300/25 mg (8 weeks). Enrolled patients (n=844) were aged 57.3+/-11.2 years; 52% were women, 23% were African American, and 14% were Hispanic. Thirty percent had type 2 diabetes mellitus, 46% had metabolic syndrome, and baseline blood pressure was 154.0+/-10.3/91.3+/-8.8 mm Hg. The mean change in SBP from placebo end to the primary end point, Week 18 (intent-to-treat population, n=736) was -21.5+/-14.3 mm Hg (p<0.001). The mean change in diastolic blood pressure (DBP) was -10.4+/-8.7 mm Hg (p<0.001). The mean Week 18 SBP/DBP was 132.9+/-13.8/81.1+/-9.7 mm Hg. Overall, 77% (95% confidence interval, 74%-80%) of patients achieved SBP goal (<140 mm Hg; <130 mm Hg for type 2 diabetes mellitus); 83% (95% confidence interval, 80%-86%) achieved DBP goal (<90 mm Hg; <80 mm Hg for type 2 diabetes mellitus); and 69% (95% confidence interval, 66%-72%) achieved dual SBP/DBP goal. Treatments were well tolerated. This irbesartan/HCTZ treatment regimen achieved SBP goals in more than 75% of patients uncontrolled on monotherapy.     

Direct Renin inhibition with aliskiren in obese patients with arterial hypertension

Current guidelines from the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure recommend first-line treatment with a thiazide diuretic but do not provide specific guidance for obese patients. The renin system is activated in obesity-associated arterial hypertension. Therefore, we tested the hypothesis that the oral direct renin inhibitor aliskiren could provide additive blood pressure lowering in obese patients with hypertension (body mass index >or=30 kg/m(2); mean sitting diastolic blood pressure: 95 to 109 mm Hg) who had not responded to 4 weeks of treatment with hydrochlorothiazide (HCTZ) 25 mg. After a 2- to 4-week washout, 560 patients received single-blind HCTZ (25 mg) for 4 weeks; 489 nonresponders were randomly assigned to double-blind aliskiren (150 mg), irbesartan (150 mg), amlodipine (5 mg), or placebo for 4 weeks added to HCTZ (25 mg), followed by 8 weeks on double the initial doses of aliskiren, irbesartan, or amlodipine. After 8 weeks of double-blind treatment (4 weeks on the higher dose), aliskiren/HCTZ lowered blood pressure by 15.8/11.9 mm Hg, significantly more (P<0.0001) than placebo/HCTZ (8.6/7.9 mm Hg). Aliskiren/HCTZ provided blood pressure reductions similar to those with irbesartan/HCTZ and amlodipine/HCTZ (15.4/11.3 and 13.6/10.3 mm Hg, respectively), with similar tolerability to placebo/HCTZ. Adverse event rates were highest with amlodipine/HCTZ because of a higher incidence of peripheral edema (11.1% versus 0.8% to 1.6% in other groups). In conclusion, combination treatment with aliskiren is a highly effective and well-tolerated therapeutic option for obese patients with hypertension who fail to achieve blood pressure control with first-line thiazide diuretic treatment.
