Hydrodiuril (Hydrochlorothiazide) - Summary



HydroDIURIL (Hydrochlorothiazide) is a diuretic and antihypertensive.

HydroDIURIL is indicated as adjunctive therapy in edema associated with congestive heart failure, hepatic cirrhosis, and corticosteroid and estrogen therapy.

HydroDIURIL has also been found useful in edema due to various forms of renal dysfunction such as nephrotic syndrome, acute glomerulonephritis, and chronic renal failure.

HydroDIURIL is indicated in the management of hypertension either as the sole therapeutic agent or to enhance the effectiveness of other antihypertensive drugs in the more severe forms of hypertension.

Use in Pregnancy. Routine use of diuretics during normal pregnancy is inappropriate and exposes mother and fetus to unnecessary hazard. Diuretics do not prevent development of toxemia of pregnancy and there is no satisfactory evidence that they are useful in the treatment of toxemia.

Edema during pregnancy may arise from pathologic causes or from the physiologic and mechanical consequences of pregnancy. Thiazides are indicated in pregnancy when edema is due to pathologic causes, just as they are in the absence of pregnancy (see PRECAUTIONS, Pregnancy). Dependent edema in pregnancy, resulting from restriction of venous return by the gravid uterus, is properly treated through elevation of the lower extremities and use of support stockings. Use of diuretics to lower intravascular volume in this instance is illogical and unnecessary. During normal pregnancy there is hypervolemia which is not harmful to the fetus or the mother in the absence of cardiovascular disease. However, it may be associated with edema, rarely generalized edema. If such edema causes discomfort, increased recumbency will often provide relief. Rarely this edema may cause extreme discomfort which is not relieved by rest. In these instances, a short course of diuretic therapy may provide relief and be appropriate.

Effects of sodium restriction and hydrochlorothiazide on RAAS blockade efficacy in diabetic nephropathy: a randomised clinical trial. [2014]
blockade on residual albuminuria in patients with type 2 diabetic nephropathy... INTERPRETATION: We conclude that sodium restriction is an effective

Long-Term Safety and Tolerability of the Oral Direct Renin Inhibitor Aliskiren with Optional Add-On Hydrochlorothiazide in Patients with Hypertension: A Randomized, Open-Label, Parallel-Group, Multicentre, Dose-Escalation Study with an Extension Phase. [2011.10.13]
BACKGROUND: Most patients with hypertension will require combination therapy with at least two agents from different antihypertensive classes to achieve blood pressure (BP) control. Thiazide diuretics, such as hydrochlorothiazide (HCTZ), are widely used in combination therapy. The volume reduction with these agents stimulates the renin-angiotensin system (RAS), making RAS inhibitors such as the direct renin inhibitor aliskiren a logical choice for combination therapy with HCTZ. OBJECTIVE: The aim of this study was to investigate the long-term safety, tolerability and efficacy of the direct renin inhibitor aliskiren, with or without addition of the diuretic HCTZ... CONCLUSION: In patients with hypertension, long-term treatment with aliskiren, with or without add-on HCTZ, is well tolerated and provides effective BP lowering that is sustained over 12 months. TRIAL REGISTRATION: ClinicalTrials.gov Identifier NCT00219037.

Chronotherapy with valsartan/hydrochlorothiazide combination in essential hypertension: improved sleep-time blood pressure control with bedtime dosing. [2011.08]
Administration of angiotensin receptor blockers at bedtime results in greater reduction of nighttime blood pressure than dosing upon awakening, independent of the terminal half-life of each individual medication. To obtain blood pressure (BP) target goals most patients require treatment with more than one hypertension medication...

Effect of valsartan, hydrochlorothiazide, and their combination on 24-h ambulatory blood pressure response in elderly patients with systolic hypertension: a ValVET substudy. [2011.08]
BACKGROUND: Stage 2 hypertension often requires combination antihypertensive therapy. Ambulatory blood pressure monitoring (ABPM) is a useful tool for studying antihypertensive drugs and their combinations. OBJECTIVE: This multicenter, double-blind, parallel-group, prompted-titration study of patients of at least 70 years of age with systolic hypertension compared the efficacy of valsartan, hydrochlorothiazide, and their combination on ambulatory blood pressure (ABP) reduction... CONCLUSION: In elderly hypertensives, starting combination therapy with valsartan/hydrochlorothiazide provides more effective 24-h blood pressure control than the monotherapy components, with few therapy-related side-effects.

A comparison of the efficacy and safety of irbesartan/hydrochlorothiazide combination therapy with irbesartan monotherapy in the treatment of moderate or severe hypertension in diabetic and obese hypertensive patients: a post-hoc analysis review. [2011.07]
Hypertension is difficult to treat in patients with type 2 diabetes mellitus (T2DM) or obesity. Combination therapies are often required to effectively lower blood pressure (BP) and attain BP goals... In patients with moderate or severe hypertension and with a BMI >/= 30 kg/m(2), initial treatment with irbesartan/HCTZ combination therapy was more effective than irbesartan monotherapy.

Clinical Trials Related to Hydrodiuril (Hydrochlorothiazide)

Aliskiren vs Hydrochlorothiazide in Hypertensive Type II Diabetic Patients on Resistance Arteries [Withdrawn]
This study will be performed only at the Jewish General Hospital. It will investigate the effect of treatment with aliskiren, an inhibitor of renin, a substance produced by the kidney that constricts arteries and raises blood pressure, on the blood vessels, specifically the arteries, of subjects who have diabetes and elevated blood pressure (hypertension). To investigate blood vessels, different techniques will be used. For large arteries, these will be studied by non invasive methods using detection of the pulse wave or using ultrasound over the skin of the neck, the wrist and the groin. To study small vessels, the investigators will perform a biopsy on the buttock, under local anesthesia, and obtain a small sample of tissue from under the skin, from which the vessels will be dissected. The investigators have performed many hundreds of these small biopsies over the past 20 years for similar studies without any complications. The biopsies are very well tolerated. From this research the investigators will thus be able to learn what the structure and function of these vessels is in these patients, in comparison to a normal healthy group. The hypertensive diabetic subjects will then be assigned by chance (randomized trial) to treatment with the renin inhibitor aliskiren or a comparator, the diuretic hydrochlorothiazide. Aliskiren is a relatively new drug used to treat hypertension that is very well tolerated and is now being evaluated in numerous trials in hypertensive diabetic individuals. The diuretic is a well-know agent used to treat high blood pressure now for many years, and which is very well tolerated. Physicians, nurses and scientists involved in the study will be unaware of who is receiving which drug, as will be the patients (this is the meaning of double-blind trial). However, if there is any problem, the secret code will be broken and the individual withdrawn from the study. Subjects will be treated for a year, and the study procedures (non invasive and the biopsy) repeated at 6 months and after one year of treatment. During the study, blood samples will be drawn and urine collected at certain intervals to ensure safety of the treatment. Once tissues are obtained they will be studied in the laboratory. The study of the vessels will allow treatment us to determine how the treatment with the renin inhibitor aliskiren affects the structure and function as well as cellular and molecular aspects of arteries of hypertensive diabetic persons. The investigators expect these studies to provide us knowledge on mechanisms and perhaps new targets for future therapies of cardiovascular disease and hypertension.

Study to Evaluate the Efficacy and Safety of Combined Administration of TAK-536CCB and Hydrochlorothiazide in Patients With Grade I or II Essential Hypertension. [Completed]
The objective of this study is to compare the efficacy and safety of combined administration of TAK-536CCB (Fix-dose combination of Azilsartan and Amlodipine) and Hydrochlorothiazide (HCTZ) with those of TAK-536CCB in patients with Grade I or II essential hypertension.
