In brief: Names say it all

Angiotensin converting enzyme(ace) inhibitor vs angiotensin receptor blocker(arb).
The names really say it all. Angiotensin which raises blood pressure needs to be activated to work. Aces prevent that activition. Arbs directly block the activity of angiotensin. Both have similar effects but there is more evidence for heart protection with aces than arbs but slightly more side effects with aces.
