Rimoldi SF et al. J Clin Hypertens (Greenwich). 2015;17(3):193-199. Efficacy and safety of calcium channel blocker/diuretics combination therapy in hypertensive patients: a meta-analysis
Methods Four studies (ELSA, VALUE, FEVER, COPE) with a total of 30 791 patients fulfilled the inclusion criteria and were included. Random-effects meta-analysis comparing ischemic outcomes between patients treated with a CCB/thiazide diuretic combination and those treated with other antihypertensive medications at maximum available follow up.

Results The combination of a CCB with a thiazide (-like) diuretic exhibited similar risks of all cause mortality (RR, 0.89; 95% CI, 0.75-1.06) and cardiovascular mortality (RR, 0.89; CI, 0.71-1.10) compared with other hypertensive medications. Moreover, the combination CCB/ thiazide (-like) diuretic was associated with a significant risk reduction for MI (RR, 0.83; CI, 0.73-0.95) and stroke (RR, 0.77; CI, 0.64-0.92) compared with other hypertensive medications.
Thiazide diuretics/calcium channel blockers: more effective than other combinations in reducing stroke CCB, calcium channel blocker; CI, confidence internval; DIU, diuretic.
Conclusions Calcium channel blocker/diuretic combination therapy is safe and efficient in reducing morbidity and mortality in hypertension. Calcium channel blocker/diuretic combination therapy may be particularly useful to reduce systolic blood pressure and to confer cerebrovascular protection.
