Last verified: May 2011
The sustained reduction in elevated blood pressure and lower incidence of adverse events of Lacidipine may provide additional benefits for hypertension patients than other CCBs (calcium channel blockers). This study is to compare the efficacy and safety of Lacidipine with Amlodipine, the most widely used CCB in Taiwan, in hypertensive patients.

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double
Primary Purpose: Treatment
Official Title: A Randomized, Double-blind, Parallel Group, Single-Centre Study to Evaluate the Efficacy and Safety of Lacidipine and Amlodipine Once-daily Treatment in Hypertensive Adult Patients

Further study details as provided by GlaxoSmithKline:

Primary Outcome Measures:
  • To evaluate the efficacy of of Lacidipine 4 or 6 mg and Amlodipine 5 or 10 mg on blood pressure profiles, in terms of blood pressure, heart rate, and edema after 8 weeks of treatment.

Secondary Outcome Measures:
  • To compare the overall safety profile of Lacidipine and Amlodipine, in terms of percentage and types of adverse events reported after 8 weeks of treatment.
