Attenuation of the kaluretic properties of furosemide by triamterene (Dyrenium) in healthy volunteers. [2005.02]
OBJECTIVE: To examine if concomitant administration of furosemide, a loop diuretic, with the potassium- and magnesium-sparing diuretic triamterene would decrease loss of potassium and magnesium while improving diuresis... CONCLUSION: Triamterene, when used in combination with the loop diuretic, furosemide, preserves intracellular potassium and magnesium while enhancing the natriuretic effect of furosemide.
Effect of quinapril and triamterene/hydrochlorothiazide on cardiac and vascular end-organ damage in isolated systolic hypertension. [1998.02]
We compared, in a prospective double-blind randomized study, the effect of the angiotensin-converting enzyme inhibitor quinapril (QUI) with that of triamterene/hydrochlorothiazide (THCT) treatment on cardiovascular end-organ damage in subjects with untreated isolated systolic hypertension (ISH)... Results of LV diastolic function and peripheral vascular resistance were less clear but appear to show less favorable changes in the THCT subjects treatment group.
Pharmacokinetics and pharmacodynamics of triamterene and hydrochlorothiazide and their combination in healthy volunteers. [1997.10]
Although triamterene has been in clinical use for over 30 years, the linearity of triamterene kinetics was not systematically tested. Moreover, although triamterene is mostly applied concomitantly with thiazide-type diuretics the interaction of triamterene (TA) with hydrochlorothiazide (HCT) is subject to a controversial discussion.
Felodipine or hydrochlorothiazide/triamterene for treatment of hypertension in the elderly: effects on blood pressure, hypertensive heart disease, metabolic and hormonal parameters. [1996.05]
The aim of the study was to compare the antihypertensive efficacy of either felodipine or the diuretic combination hydrochlorothiazide/triamterene in a group (n = 65) of elderly (> or = 70 years) hypertensives (office blood pressure > or = 160/95 mmHg) with special regard to ambulatory blood pressure monitoring, hypertensive heart disease and metabolic parameters...
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...
Clinical Trials Related to Dyrenium (Triamterene)
Hemodialysis Without Anticoagulation in Intensive Care Unit [Recruiting]
The purpose of this study is to determine the safety and operative efficacy of intermittent
hemodialysis without anticoagulation with saline flushes or Nephral 400ST in patients at high
risk of bleeding
Diuretics, Hypertension, and Arrhythmias Clinical Trial [Completed]
To determine whether hypertensive patients with ECG abnormalities and receiving
hydrochlorothiazide diuretics were at increased risk of sudden death.
Renin-Guided Therapeutics in the Management of Untreated, Uncontrolled, or Complicated Hypertension [Completed]
Plasma renin values determine whether volume or vasoconstrictor (renin) factors predominate
in elevating blood pressure and are useful in selecting effective antihypertensive
therapy. 2,3
The researchers hypothesize that:
1. Plasma renin-guided therapeutics will improve systolic and diastolic blood pressure
control in patients with untreated hypertension as well as in patients with treatment
refractory or resistant hypertension that are managed by Clinical Hypertension
Specialists.
2. Renin-guided therapeutics will reduce the number of medications required to maintain
blood pressure control to <140/90 mmHg in hypertensive patients receiving 3 or more
medications, while under the care of a Clinical Hypertension Specialist.
3. Renin-guided therapeutics selection will reduce the total cost of antihypertensive care
provided by Clinical Hypertension Specialists.
Chronic Hemodialysis Without Systemic Heparinization : a Randomized Study [Recruiting]
Conventional hemodialysis requires transient systemic anticoagulation to prevent blot
clotting after contact with the extracorporeal circuit. However, low molecular weight heparin
(LMWH) or unfractioned heparin are contra-indicated in dialysis patients at risk for
hemorrhagic complications. In this setting, several procedures theoretically allow dialysis
without systemic heparinization, but randomized studies to compare them are lacking. The
gold standard is the use of iterative rises of the extra corporeal circuit with isotonic
saline (« rises »). Two emerging procedures are increasingly used : continuous pre-dilution
of the arterial line (« pre-dilution ») and the use of a specific dialysis membrane (NEPHRAL
400 ST) coated with heparin immediately before use (« heparin adsorption »).
