Further study details as provided by Merck Sharp & Dohme Corp.:

Primary Outcome Measures:
  • Losartan-HCTZ 100-12.5 mg combination will be more effective in lower mean through sitting diastolic blood pressure (SiDBP) than losartan 100 mg monotherapy after 6 weeks of treatment. [ Time Frame: 6 Weeks ]

Secondary Outcome Measures:
  • Losartan-HCTZ 100-12.5 mg combination will be more effective in lowering mean through sitting systolic blood pressure (SiSBP) after 6 weeks of treatment compared to losartan 100-mg monotherapy, and will be safe and tolerable. [ Time Frame: 6 Weeks ]

Enrollment: 274
Actual Study Start Date: December 1, 2004
Study Completion Date: June 2, 2005
Primary Completion Date: June 1, 2005 (Final data collection date for primary outcome measure)
