A randomized titrate-to-target study comparing fixed-dose combinations of azilsartan medoxomil and chlorthalidone with olmesartan and hydrochlorothiazide in stage-2 systolic hypertension (original) (raw)

Safety, Tolerability, and Efficacy of Azilsartan Medoxomil With or Without Chlorthalidone During and After 8 Months of Treatment for Hypertension

Journal of clinical hypertension (Greenwich, Conn.), 2015

A phase 3, 26-week, open-label, titrate-to-target study (n=418) assessed the safety of azilsartan medoxomil (AZL-M) alone and with chlorthalidone (CLD), followed by a 6-week, double-blind, placebo-controlled reversal phase with change in clinic diastolic blood pressure (DBP) as the primary endpoint. Target blood pressure (BP) was <140/90 mm Hg (<130/80 mm Hg with diabetes/chronic kidney disease). AZL-M was initiated at 40 mg once a day (QD), force-titrated to 80 mg at week 4. CLD 25 mg QD could be added (weeks 8-22), if required, to reach target, followed by additional antihypertensives from week 12. At the end of the open-label phase, mean change in systolic BP (SBP)/DBP from baseline was -23/-16 mm Hg. The most common adverse events, irrespective of treatment, were dizziness (8.9%) and headache (7.2%). Serious AEs were reported in eight patients (1.9%). Consecutive creatinine elevations ≥50% with values exceeding the upper limit of normal (ULN) were reported in nine (2.2%) p...
