Additivity of nebivolol/valsartan single-pill combinations versus other single-pill combinations for hypertension.

The single-pill combination (SPC) comprising nebivolol (5mg), a vasodilatory (1)-selective antagonist/(3)-agonist, and valsartan (80mg), a renin-angiotensin-aldosterone system inhibitor, is the only Food and Drug Administration-approved -blocker/renin-angiotensin-aldosterone system inhibitor SPC for hypertension. Additive effects of four nebivolol/valsartan SPC doses (5mg/80mg, 5/160mg, 10/160mg, 10/320mg nebivolol/valsartan) were compared with five Food and Drug Administration-approved non--blocker/renin-angiotensin-aldosterone system inhibitor SPCs (aliskiren/hydrochlorothiazide, aliskiren/amlodipine, valsartan/amlodipine, aliskiren/valsartan, and telmisartan/amlodipine). Additivity is the ratio of placebo-adjusted SPC blood pressure (BP) reduction to the placebo-adjusted monotherapy component BP reduction sums. A weighted average of comparator scores was calculated and compared vs nebivolol/valsartan. Additivity ratio scores for nebivolol/valsartan SPCs (diastolic BP range: 0.735-0.866; systolic BP range: 0.717-0.822) were similar to the comparator weighted average (diastolic BP: 0.837; systolic BP: 0.825). Among the nebivolol/valsartan SPCs, 5/80mg had the greatest additivity (diastolic BP: 0.866; systolic BP: 0.822). BP reduction contributions with monotherapy were similar for nebivolol/valsartan 5/80 mg SPC. Additivity scores for nebivolol/valsartan and select non--blocker/renin-angiotensin-aldosterone system inhibitor SPCs were comparable.
