What are ACE-I? How do they work? When do you use them? What do you have to look out for?
They inhibit the ACE enzyme which converts angioI to angioII. Angio II vasoconstricts. SO if you prevent the ACE enzyme, there is no vasoconstriction.
Use them with HTN patients that have DM, CKD and as an add on to those that had MI or some heart problem already.
Look out for hyperkalemia, people with renal problems.
