Mechanism of Action: This is a combination of two drugs used to treat high blood pressure. Olmesartan is an ARB that widens blood vessels, while Hydrochlorothiazide is a thiazide diuretic that increases the excretion of salt and water by the kidneys. The dual action provides a more powerful blood pressure-lowering effect than either drug alone.

Indications: It is used to treat hypertension (high blood pressure), especially in patients who are not adequately controlled by a single medication.
