This is a multi-centre, individual randomized single-blind, parallel group, three-armed superiority trial to compare the efficacy of three different single-pill combinations of antihypertensive therapies (Amlodipine/Perindopril, Perindopril/Indapamide, and Amlodipine/Indapamide)on 24-hour ambulatory BP levels in Indians.
Hypertension is a leading cause of morbidity and mortality globally. Although multiple drugs are frequently used to treat it, in the South Asian context, evidence is lacking on best drug combinations. This trial aims to compare efficacy of three single-pill combinations of two anti-hypertensive agents on 24-hour ambulatory systolic blood pressure among 1968 individuals with hypertension. The trial is a single-blind randomized controlled trial spread across 15 hospitals in India.~Single Pill combinations (SPCs): 1) Amlodipine + Perindopril, 2) Perindopril + Indapamide, 3) Amlodipine + Indapamide
