Authors' conclusion

This meta-analysis of short-term randomized clinical trials found that adverse drug effects that led to discontinuation of BP-lowering therapy varied by drug class and regimen, with several combination therapies being better tolerated than monotherapies.

Study context

Population
Participants in short-term double-blind RCTs of ACE inhibitors, ARBs, β-blockers, calcium channel blockers (CCBs), thiazide/thiazide-like diuretics or combinations (mean age 54.6 years; 44% female; mean baseline blood pressure (BP) 158/100 mm Hg)
Participants
159,362 participants · 716 trials
Comparison
BP-lowering drug classes and combinations vs placebo
Outcome
Treatment discontinuation due to AEs
