Arms and Interventions

Outcome Measures

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

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