What is Dyazide?

Dyazide (generic name: hydrochlorothiazide and triamterene) is an oral medication indicated to treat hypertension or edema among patients who develop hypokalemia or hydrochlorothiazide alone. This medication can also be used to manage patients who require a thiazide diuretic and for those whose development of hypokalemia cannot be risked. Additionally, it could be used as an adjunct to antihypertensive agents, like beta-blockers.

This is available in Dyazide 37.5 mg triamterene / 25 mg hydrochlorothiazide capsule forms.

Mechanism of Action

This medication is a combination of natriuretic and antidiuretic, and both components complement the actions of each other. It works by blocking the process of sodium reabsorption and chloride ions which increases the quantity of sodium traveling across the distal tubule and the volume of water excreted. The additional sodium is exchanged for potassium and hydrogen ions which decreases the glomerular filtration rate. This medication can also reduce renal plasma flow.
