Placebo to losartan once daily for 4 weeks in run-in period. Then, losartan 50 mg for 4 weeks, then titrate to losartan 100 mg at Week 4, then titrate to losartan 100 mg + hydrochlorothiazide (HCTZ) 12.5 mg at Week 8, and finally titrate to losartan 100 mg + HCTZ 25 mg at Week 12. Duration of treatment is approximately 16 weeks.
Placebo to losartan once daily for 4 weeks in run-in period. Then, placebo to losartan or losartan/HCTZ once daily for approximately 16 weeks.
Mean Change From Baseline in Trough Sitting Systolic Blood Pressure (SiSBP) at Week 8
Mean change from baseline in trough (6 hours after last morning dose) SiSBP at Week 8. A mixed effects model (with repeated measurements including terms of treatment, investigators, week, baseline SiSBP(/SiDBP), plasma glucose stratum, treatment\*week, and week\*SiSBP(/SiDBP)) was used to compare the treatments on the change from baseline.
Time frame: At baseline and at 8 weeks (with the measurements taken prior to the morning dose, between 6 AM and 10 AM)
Mean Change From Baseline in Trough Sitting Diastolic Blood Pressure (SiDBP) at Week 8
Mean change from baseline in trough (6 hours after the last morning dose) SiDBP at Week 8. A mixed effects model (with repeated measurements including terms of treatment, investigators, week, baseline SiSBP(/SiDBP), plasma glucose stratum, treatment\*week, and week\*SiSBP(/SiDBP)) was used to compare the treatments on the change from baseline.
Time frame: At baseline and at 8 weeks (with the measurements taken prior to the morning dose, between 6 AM and 10 AM)
Mean Change From Baseline in Trough Sitting Diastolic Blood Pressure (SiDBP) at Week 12
Mean change from baseline in trough (6 hours after the last morning dose) SiDBP at Week 12.
