Adverse effects of hypertensive agents
A systematic review 1 including 28 RCTs with a total of 3073 subjects assessing calcium channel blockers (CCB) versus beta blockers or diuretics was abstracted in DARE. There was no difference in the total incidence of serious adverse effects. Headache and oedema occurred significantly more frequently in CCB. The risk difference between CCBs and diuretics was 7.36% (95% CI 1.90 to 12.81%) for headache and 6.57% (95% CI 1.29% to 11.84%) for oedema. Flushing occurred 8.75% more frequently with CCBs compared with beta blockers (95% CI 4.00% to 13.94%). Tachycardia and oedema occurred in the CCB group slightly more frequently than beta blockers (difference not statistically significant).
Comment: A well performed systematic review.
