Thiazide diuretics for high blood pressure

Solutions for high blood pressure often include diuretics

Thiazide diuretics are the most commonly used medications for high blood pressure because they inhibit the reabsorption of sodium in the kidney, which is known as the distal tubule.

Although this section normally removes only 5 percent of the original sodium, the amount of water reduces the volume of blood sufficiently to lower blood pressure.

Loop diuretics, on the other hand, have a greater impact on the levels of sodium, and typically absorb about 25 percent of the sodium.

Because these drugs are much more effective in reducing blood pressure, this type of diuretics also has far more side-effects, including lethargy, muscle cramps, weakness and dizziness.

Potassium-sparing diuretics help with an excessive loss of potassium, but they are also less effective in reducing the sodium and water content of the blood.

Widespread diuretics

Many different diuretics are available to treat hypertension or high blood pressure, some of the following are commonly prescribed:


Hydrochlorothiazide, also known as HCTZ



Effectiveness of diuretics

Most patients with primary hypertension, which account for about 90 to 95 percent of all cases, respond favourably to treatment with a diuretic.

To increase the effectiveness of these drugs, most doctors recommend the implementation of certain lifestyle changes.

The increase in physical activity along with weight loss, smoking cessation, and a reduced sodium intake can help to increase the effectiveness of these drugs to lower blood pressure more effectively.
