I et studie med 722 randomiserede patienter, der ikke responderede tilstrækkeligt på behandling med hydrochlorthiazid 25 mg, viste kombinationen af aliskiren/ hydrochlorthiazid 300 mg/ 25 mg systoliske/ diastoliske blodtryksreduktioner på 16, 78/ 10, 7 mmHg, hvilket var signifikant større end for hydrochlorthiazid 25 mg monoterapi.
In a study in 722 randomised patients not adequately responsive to hydrochlorothiazide 25 mg treatment, the combination of aliskiren/ hydrochlorothiazide 300 mg/ 25 mg produced systolic/ diastolic blood pressure reductions of 16.78/ 10.7 mmHg, which were significantly greater than hydrochlorothiazide 25 mg monotherapy.
