Hypotension with angiotensin receptor blockers

Angiotensin receptor blockers show similar tolerability to ACE inhibitors with regard to hypotension and hyperkalemia, but they do not induce cough since ARBs do not cause an accumulation of bradykinin. Angiotensin receptor blockers can be considered in patients with ACE inhibitor-induced angioedema, but they should be initiated cautiously, as crossreactivity has been reported. Many of the other considerations for the use of ARBs are similar to those of ACE inhibitors,... 

Besides hypotension, the most frequent adverse reaction to an ACE inhibitor is cough, which may occur in up to 30% of patients. Patients with ACE inhibitor cough and either clinical signs of heart failure or LVEE less than 40% may be prescribed an angiotensin-receptor blocker (ARB). Both candesartan and valsartan have improved outcomes in clinical trials in patients with heart failure. Other less common but more serious adverse effects of ACE inhibitors include acute renal failure, hyperkalemia, and angioedema. Although some data have suggested that aspirin use may decrease the benefits from ACE inhibitor treatment, a systematic review of more than 20,000 patients demonstrated that ACE inhibitors improve outcome irrespective of treatment with aspirin. ...
