Official Title:	A Randomized, Open-Label, Multicentric Parallel Group Study to Assess the Impact of Supportive Measures on the Drug Adherence of Patients With Essential Hypertension Treated With Valsartan or Valsartan Plus HCTZ for 34 Weeks With or Without Respective Measures

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.

Estimated Enrollment:	220
Study Start Date:	November 2005
