Hypertension
Conditions
Brief summary
This trial aims to compare the efficacy of several guideline-based hypertensive medication regimens initiated with Angiotensin Converting Enzyme Inhibitor/Angiotensin Receptor Blocker \[A\], Calcium Channel Blocker \[C\] and Diuretic \[D\].
Detailed description
The LIGHT-ACD Trial is conducted based on the LIGHT trial and aims to compare the efficacy of several guideline-based hypertensive medication regimens initiated with A, C and D for BP control.
Interventions
The BP-lowering medication adjustment and titration will follow A-AC-ACD or A-AD-ADC for individuals randomized to A or two-drug combination therapy with full dose of A in their initial medication assignment.
The BP-lowering medication adjustment and titration will follow C-CA-CAD or C-CD-CDA for individuals randomized to C or two-drug combination therapy with full dose of C in their initial medication assignment.
The BP-lowering medication adjustment and titration will follow D-DA-DAC or D-DC-DCA for individuals randomized to D or two-drug combination therapy with full dose of D in their initial medication assignment.
