Hydrochlorothiazide is taken by mouth and may be combined with other blood pressure medications as a single pill to increase effectiveness. [4] Hydrochlorothiazide is a thiazide medication which inhibits reabsorption of sodium and chloride ions from the distal convoluted tubules of the kidneys, causing a natriuresis.
Regardless of the cause, someone may have very high hypertension without any initial symptoms. Uncontrolled hypertension will eventually cause damage to the heart, kidneys and eyes. Lifestyle changes, including reducing dietary salt, increasing exercise and losing weight can help to reduce blood pressure. [9]
Antihypertensive therapy seeks to prevent the complications of high blood pressure, such as stroke, heart failure, kidney failure and myocardial infarction. Evidence suggests that reduction of the blood pressure by 5 mmHg can decrease the risk of stroke by 34% and of ischaemic heart disease by 21%, and can reduce the likelihood of dementia ...
A secondary effect of loop diuretics is to increase the production of prostaglandins, which results in vasodilation and increased blood supply to the kidney. [ 8 ] [ 9 ] Prostaglandin-mediated vasodilation of preglomerular afferent arterioles increases the glomerular filtration rate (GFR) and facilitates diuresis.
[2] [3] Other serious side effects may include high blood potassium. [2] [3] Use in pregnancy and breastfeeding is not generally recommended. [2] [3] Use in those with significant kidney problems is not recommended. [2] [3] It decreases blood pressure mainly by hydrochlorothiazide while triamterene decreases the amount of potassium lost.

Lisinopril/hydrochlorothiazide, sold under the brand name Zestoretic among others, is a fixed-dose combination medication used for the treatment of high blood pressure (hypertension). [2] It contains lisinopril , an ACE inhibitor , and hydrochlorothiazide , a diuretic .
Olmesartan/hydrochlorothiazide, sold under the brand name Benicar HCT among others, is a fixed-dose combination medication used to treat high blood pressure. [ 1 ] [ 2 ] It is a combination of olmesartan medoxomil , an angiotensin II receptor blocker and hydrochlorothiazide , a diuretic . [ 2 ]
Osmotic diuretics work by expanding extracellular fluid and plasma volume, therefore increasing blood flow to the kidney. This washes out the cortical medullary gradient in the kidney. This stops the loop of Henle from concentrating urine, which usually uses the high osmotic and solute gradient to transport solutes and water.
