Further study details as provided by Novartis:

Primary Outcome Measures:
  • Drug adherence in patients (daily proportion of patients taking one tablet of the prescribed hypertensive therapy as prescribed)

Secondary Outcome Measures:
  • Compliance and persistence between randomized groups over time.
  • To assess discrepancies between pill counts, Morisky questionnaire and electronic monitoring to estimate patient adherence to prescribed therapy
  • To assess the relation between drug exposure and BP reduction.
  • To assess the relation between drug exposure and the likelihood to switch to valsartan 160 mg plus HCTZ 12.5 mg
  • To assess the safety and tolerability of valsartan 160 mg and valsartan 160 mg plus
  • HCTZ 12.5 mg.
