How does the enalapril component of enalapril maleate + hydrochlorothiazide lower blood pressure?

In Innozide (enalapril maleate + hydrochlorothiazide), enalapril becomes enalaprilat, which inhibits ACE and reduces angiotensin II formation and aldosterone secretion; blood-pressure lowering is believed to occur primarily through suppression of the renin–angiotensin–aldosterone system, although enalapril also works in low-renin hypertension.
