Which of the following is a common fixed-dose combination of thiazides?

The correct answer is a commonly used combination that includes a thiazide diuretic. Hydrochlorothiazide is a thiazide diuretic that lowers blood pressure by reducing fluid volume and the workload on the heart. When combined with Lisinopril, an ACE inhibitor, the synergy of these two medications can provide better blood pressure control and offer renal protective benefits, particularly in patients with diabetes.

In contrast, the pairing of Triamterene + Dyazide features a thiazide diuretic (Hydrochlorothiazide) with a potassium-sparing diuretic (Triamterene) rather than a fixed-dose combination of two thiazides. This combination is effective as well but does not purely represent the context of fixed-dose combinations of thiazide medications themselves.

Amiloride and Moduretic, along with Spironolactone and Furosemide, do not represent fixed-dose combinations of thiazide diuretics. Instead, they focus on different classes and mechanisms of diuretics. Therefore, the option that stands out for being a common fixed-dose combination involving a thiazide is Hydrochlorothiazide + Lisinopril, as it not only incorporates a th
