Cannot give to someone with asthma: always check hr, bp. Block beta 1 more than 2- work primarily on heart. Nonselective: effect beta 1 and beta 2. Prevents the production of angiotensin ii from angiotensin i. Angiotensin 2 is one of the most potent vasoconstrictors. Drug of choice with diuretics with pts who have chronic chf. Pts can develop orthostatic htn, dry cough, angioedema (medical emergency) Ace is found in the lungs which is why there is a dry cough. Inhibit ca from crossing cardiac and smooth muscle cells.
