Aliskiren, an enzyme necessary for the conversion of angiotensinogen into angiotensin I, is a direct inhibitor of renin. It reduces the activity of plasma renin, thereby inhibiting the production of angiotensin II and aldosterone. In distal tubules, hydrochlorothiazide prevents sodium reabsorption, causing increased excretion of sodium and water, including potassium and hydrogen ions.
