Telmisartan hydrochlorothiazide is an anti-hypertension medicine that is a combination of two drugs– telmisartan, an angiotensin receptor, and hydrochlorothiazide, a thiazide diuretic. This drug is used to treat high blood pressure.

Telmisartan accomplishes its functions by blocking the vasoconstricting effects of angiotensin II by binding to receptors. Hydrochlorothiazide exerts its effects on the distal tubules of the kidney to increase the secretion of water, sodium and chloride ions. It decreases the reabsorption of electrolytes from the kidney tubules.

Telmisartan hydrochlorothiazide is used in the treatment of the following:
