Til sammenligning blev der set en normalisering af blodtrykket hos 53% af patienterne, som forblev på valsartan 160 mg.
A multicentre, randomised, double-blind, active-controlled, parallel-group trial showed normalisation of blood pressure (trough sitting diastolic blood pressure < 90 mmHg at the end of the trial) in patients not adequately controlled on valsartan 160 mg in 75% of patients treated with amlodipine/ valsartan 10 mg/ 160 mg and 62% of patients treated with amlodipine/ valsartan 5 mg/ 160 mg, compared to 53% of patients remaining on valsartan 160 mg.
