Introduction
In general, hydrochlorothiazide tablets can lower blood pressure, but medication use must follow medical advice. When using hydrochlorothiazide tablets to reduce blood pressure, it is necessary to ensure the appropriateness of dosage and frequency. Overuse may cause hypokalemia and affect lipid, glucose, and uric acid metabolism. Patients with anuria, severe renal impairment, hyperuricemia, gout, hypercalcemia, or hyponatremia should use this medication with caution.
Generally speaking, hydrochlorothiazide tablets can lower blood pressure, but medication use must follow medical advice. The detailed explanation is as follows:
Hydrochlorothiazide tablets are a type of diuretic antihypertensive drug. They mainly inhibit the reabsorption of sodium chloride in the distal and proximal convoluted tubules of the kidney, increasing the excretion of urinary sodium, potassium, chloride, and other ions, thereby reducing extracellular fluid volume, lowering peripheral vascular resistance, and ultimately achieving blood pressure reduction. Its blood pressure-lowering effect is steady and long-lasting, particularly suitable for mild to moderate hypertension. It also shows good efficacy for isolated systolic hypertension, salt-sensitive hypertension, elderly hypertension, and hypertension accompanied by obesity, diabetes, or heart failure.
When using hydrochlorothiazide tablets to lower blood pressure, it is essential to ensure appropriate dosage and frequency. Overuse may cause hypokalemia and affect lipid, glucose, and uric acid metabolism. Patients with anuria, severe renal impairment, hyperuricemia, gout, hypercalcemia, or hyponatremia should use it with caution.
