Moduretic (Amiloride Hydrochloride / Hydrochlorothiazide) - Summary



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.

Published Studies Related to Moduretic (Amiloride / Hydrochlorothiazide)

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)

Amiloride Hydrochlorothiazide as Treatment of Acute Inflammation of the Optic Nerve [Recruiting]
Following acute inflammation of the optic nerve region, as commonly seen in multiple sclerosis patients, the optic nerve often undergoes atrophy, thus representing permanent damage. Data from animal studies suggest that amiloride may prevent this process. The aim of this study is to assess a potential neuroprotective effect of amiloride in acute autoimmune inflammation of the optic nerve region.

Pharmacologic Treatment of Congenital Nephrogenic Diabetes Insipidus [Completed]
The purpose of this research study is to determine if two investigational medications will be more effective in decreasing urine output than the currently available and routinely used medications in patients with congenital nephrogenic diabetes insipidus (NDI).
