Mechanism of action

The mechanism of action of hydrochlorothiazide involves its ability to inhibit the reabsorption of sodium and chloride ions in the distal convoluted tubules of the kidneys. This leads to increased excretion of water and electrolytes, including sodium, chloride, and potassium. By increasing the excretion of water, hydrochlorothiazide helps reduce the volume of fluid in the blood vessels, which in turn reduces blood pressure.

Inhibition of sodium and chloride reabsorption

Hydrochlorothiazide works by blocking a specific transporter protein called the sodium-chloride symporter in the cells lining the distal convoluted tubules. This transporter is responsible for reabsorbing sodium and chloride ions from the urine back into the bloodstream. By inhibiting this transporter, hydrochlorothiazide prevents the reabsorption of sodium and chloride ions and promotes their excretion in the urine.

Increased urine output

As a result of the inhibited reabsorption of sodium and chloride, hydrochlorothiazide increases the osmolarity of the urine. This osmotic effect draws water into the urine, leading to increased urine output. By increasing urine output, hydrochlorothiazide helps eliminate excess fluid from the body and reduce fluid overload.

Overall, the mechanism of action of hydrochlorothiazide involves blocking the reabsorption of sodium and chloride ions, promoting their excretion in the urine, and increasing the excretion of water. This helps reduce blood volume and ultimately lowers blood pressure.
