MODURETIC (Amiloride HCl-Hydrochlorothiazide) combines the potassium-conserving action of amiloride HCl with the natriuretic action of hydrochlorothiazide.
MODURETIC is indicated in those patients with hypertension or with congestive heart failure who develop hypokalemia when thiazides or other kaliuretic diuretics are used alone, or in whom maintenance of normal serum potassium levels is considered to be clinically important, e.g., digitalized patients, or patients with significant cardiac arrhythmias.
The use of potassium-conserving agents is often unnecessary in patients receiving diuretics for uncomplicated essential hypertension when such patients have a normal diet.
MODURETIC may be used alone or as an adjunct to other antihypertensive drugs, such as methyldopa or beta blockers. Since MODURETIC enhances the action of these agents, dosage adjustments may be necessary to avoid an excessive fall in blood pressure and other unwanted side effects.
This fixed combination drug is not indicated for the initial therapy of edema or hypertension except in individuals in whom the development of hypokalemia cannot be risked.

Effectiveness of digitoxin versus trichlormethiazide/amiloride in congestive heart failure NYHA class II/III and sinus rhythm. [1999.05]
The effects of digitoxin and/or diuretic agents were investigated in patients with congestive heart failure (CHF) in sinus rhythm with respect to changes in hemodynamic parameters, cardiac dimensions, and bicycle ergometric exercise capacity. In a randomized, double-blind study 16 male patients with CHF NYHA class II and III received a placebo for 1 week (baseline) and then were randomly allocated, double blind, to take either digitoxin (digitalis group, DI: N = 8) or trichlormethiazide/amiloride (diuretic group, DG: N = 8) for 3 weeks (VP I)...
The influence of perindopril and the diuretic combination amiloride+hydrochlorothiazide on the vessel wall properties of large arteries in hypertensive patients. [1995.08]
OBJECTIVE: To compare the cardiovascular effects of 6 months of treatment with the angiotensin converting enzyme inhibitor perindopril and with the diuretic combination amiloride+hydrochlorothiazide, and to study possible persistence of observed treatment effects after discontinuation of antihypertensive therapy... CONCLUSION: The distensibility of the elastic common carotid artery was increased by perindopril, but not by amiloride+hydrochlorothiazide. Large-artery properties of the muscular arteries and systemic vascular resistance improved with both drugs, but in general the changes were more pronounced with perindopril than with amiloride+hydrochlorothiazide. The present results indicate a more pronounced effect of perindopril at both macro- and microcirculatory levels, which will consequently lead to a larger decrease in cardiac afterload. After discontinuation of therapy all parameters returned to baseline values within 7 weeks.
A study of plasma sodium levels in elderly people taking amiloride or triamterene in combination with hydrochlorothiazide. [1993.10]
This study was performed to compare the effect of one month's treatment with hydrochlorothiazide (25 mg) in combination with either amiloride (2.5 mg) or triamterene (50 mg) on plasma sodium levels in elderly people in institutional care. Fifty residents of NHS nursing or social service residential care established on diuretics for congestive cardiac failure and aged 64 years or over were recruited...
[Double blind comparative randomized study of the efficacy of celiprolol versus amiloride-hydrochlorothiazide in mild to moderate AHT] [1993.05]
We tried to assess the antihypertensive effectivity of a betablocker, celiprolol, in the control of mild to moderate essential arterial hypertension. A double-blind randomized comparative study was conducted between celiprolol and amiloride-hydrochlorothiazide in 40 patients with mild to moderate essential hypertension...
A comparison of the potassium and magnesium-sparing properties of amiloride and spironolactone in diuretic-treated normal subjects. [1993.04]
1. The relative potencies of amiloride (5 and 20 mg) and spironolactone (25 and 100 mg) for plasma and erythrocyte electrolytes were investigated in a double-blind, randomised, balanced, crossover study in 12 normal men treated concomitantly with hydrochlorothiazide 100 mg daily for 1 week...
Clinical Trials Related to Moduretic (Amiloride / Hydrochlorothiazide)
Efficacy of Irbesartan/Hydrochlorothiazide Versus Valsartan/Hydrochlorothiazide in Mild to Moderate Hypertension [Recruiting]
The primary objective is to compare the efficacy of irbesartan/hydrochlorothiazide 300/25mg
against valsartan/hydrochlorothiazide 160/25mg in reducing mean systolic blood pressure (SBP)
as measured by home blood pressure monitoring (HBPM) after 24 weeks compared with baseline.
The secondary objectives are:
- To compare the percentage of patients with normal blood pressure as measured by HBPM and
at the doctor's office at weeks 16 and 24
- To compare the differences in mean Diastolic Blood Pressure (DBP), mean morning and
evening SBP and DBP evaluated by HBPM at weeks 16 and 24
- To compare the difference in mean SBP evaluated by HBPM at week 16
- To compare the differences in mean SBP and DBP evaluated at the doctor's office at weeks
16 and 24
- To determine the incidence and severity of adverse events
Irbesartan/Hydrochlorothiazide and Irbesartan in the Treatment of Mild to Moderate Hypertension [Completed]
Study Objectives :
- To demonstrate the reduction in office Blood Pressure following a 8-week regimen of
irbesartan / hydrochlorothiazide using irbesartan as a reference.
- To demonstrate the reduction in office Blood Pressure after 4-week regimen of irbesartan
/ hydrochlorothiazide using irbesartan as a reference.
- To compare the response rate (defined as office Systolic Blood Pressure/Diastolic Blood
Pressure reduce more than 10mmHg from Week 0) of patients after 4-week and 8-week
regimen of irbesartan / hydrochlorothiazide versus irbesartan.

irbesartan/hydrochlorothiazide versus irbesartan
- To ascertain the safety and tolerability of irbesartan / hydrochlorothiazide versus

A Comparison of Telmisartan + Hydrochlorothiazide With Amlodipine + Hydrochlorothiazide in the Control of Blood Pressure in Older Patients With Predominantly Systolic Hypertension. (ATHOS Study) [Completed]
The primary objective of this clinical trial was to show that the combination of telmisartan
80 mg + hydrochlorothiazide (HCTZ) 12. 5 mg was not inferior to and was possibly superior to
amlodipine 10 mg + HCTZ 12. 5 mg in reducing the systolic blood pressure (SBP) in the last six
hours of the 24-hour dose period [as measured by 24-hour ambulatory blood pressure monitoring
( ABPM)] in elderly patients with predominantly systolic hypertension. The primary endpoint
was the change from baseline in SBP in the last six hours of the 24-hour dose period (as
measured by 24-hour ABPM) at the end-of-study visit.
Efficacy and Safety of Valsartan, Hydrochlorothiazide and Amlodipine Combination Therapy in Hypertension [Completed]
This study is designed to evaluate the efficacy and safety of the combination valsartan with
hydrochlorothiazide and amlodipine in hypertensive patients previously treated with valsartan
with hydrochlorothiazide and remaining uncontrolled. A naturalistic approach will be taken
comparing two different possible ways to achieve the higher dosage of the triple combination,
i. e. 160 mg of valsartan and 25 mg of hydrochlorothiazide with amlodipine 10 mg.
