Primary Outcome Measures:
  • Changes in 24 hours mean ambulatory blood pressure on the missing dose day. Frequency, severity, seriousness of adverse events emerging during the treatment , and their relation with the study drug. [ Time Frame: at the end of 6th months to 8th ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Diastolic blood pressure measurements recorded in patients' diaries, and during visits. [ Time Frame: 6-8 weeks ] [ Designated as safety issue: No ]
