Overview of Hydrochlorothiazide

Hydrochlorothiazide is a medication commonly used to treat high blood pressure and fluid retention (edema) in the body. It belongs to a class of drugs known as diuretics, which work by increasing the amount of urine produced by the kidneys, thereby reducing the amount of fluid in the body. This helps to lower blood pressure and alleviate swelling caused by conditions such as congestive heart failure, kidney disorders, and liver disease.

How Does Hydrochlorothiazide Work?

Hydrochlorothiazide works by inhibiting the reabsorption of sodium and chloride ions in the kidney tubules. This increases the excretion of these ions in the urine, along with water. By promoting the excretion of salt and water, hydrochlorothiazide helps to reduce the volume of blood circulating through the body. This, in turn, lowers the workload on the heart and decreases blood pressure.

In addition to its diuretic effects, hydrochlorothiazide also has mild vasodilatory properties, meaning it can help to widen blood vessels and improve blood flow. This further contributes to its antihypertensive (blood pressure-lowering) effects.
