Demonstrate that telmisartan 80mg was at least as effective and possibly superior to ramipril 5mg & 10mg in lowering mean ambulatory DBP and SBP during the last 6 hrs of the 24-hr dosing interval in mild-to-moderate hypertensives at the end of 8 and 14 week treatment phases.

Primary Outcome Measures:
  • Change from baseline in the last 6-hr mean DBP & SBP as measured by ABPM at the end of and 8-wk treatment period (T80 vs R5 mg) and 14-wk treatment period (T80 vs R10 mg)

Secondary Outcome Measures:
  • Change from baseline in last 6-hr ABPM mean for: pulse pressure; DBP, SBP and PP; DBP/SBP/PP in the morning, daytime and nighttime periods of the 24-hr dosing interval; Change from baseline in mean, seated, trough DBP & SBP measured by manual cuff
