Combating Hypertension in India: The Case for Two-in-One Therapy

A New Evidence-Based Approach for South Asian Populations

✍️ By Suryavanshi IAS | For UPSC Aspirants | Public Health • Science & Tech • GS II/GS III

📍 Introduction

Hypertension, often called the “silent killer,” remains one of India’s most underdiagnosed and poorly managed public health challenges. While global guidelines—largely based on Western populations—have shaped treatment norms for decades, a new Indian study challenges the status quo.

A recent multi-centre study published in Nature Medicine, titled “Comparison of Dual Therapies for Hypertension Treatment in India”, brings a transformative perspective to how we start treating high blood pressure, especially in South Asian populations.

🧪 Study Highlights

Sample Size: ~2,000 adults with untreated or uncontrolled hypertension
Age Group: 30–79 years
Duration: 6 months
Trial Sites: 32 locations across India

✅ Drug Combinations Tested (Single-Pill Dual Therapy):

Amlodipine + Perindopril
Perindopril + Indapamide
Amlodipine + Indapamide

🎯 Key Findings:

All three combinations lowered blood pressure equally and effectively.
No significant safety differences between them.
High tolerability, even among older patients.
Side effects were mild: foot swelling, dry cough, and low potassium (non-significant).

🩺 What’s New? The Half-Dose Revolution

Lead researcher Dr. Prabhakaran Dorairaj from Centre for Chronic Disease Control, New Delhi, highlights a crucial shift:

“We are not recommending polypharmacy. We’re suggesting starting with half doses of two drugs in a single pill. If BP remains uncontrolled, only then escalate.”

This “start low and combine” approach contrasts with the traditional method of escalating one drug’s dose gradually.

⚠️ Why This Matters for India

Only 20% of hypertensive patients in urban India are controlled to target.
Rural control rates are even worse.
Current practices are guided largely by Western studies, which may not reflect South Asian genetics, diet, and risk factors.

🔁 Benefits of Dual Therapy Approach:

Benefit	Impact
✅ Faster BP control	Reduces risk of heart attacks, strokes
✅ Fewer side effects	Increases treatment adherence
✅ Better long-term control	Reduces public health burden
✅ Combats patient reluctance	Especially important in India where many avoid starting medication

👩‍⚕️ Expert Voices

“Even cardiologists often prefer to escalate single drug doses slowly. This trial shows that two low-dose drugs are more effective right from the beginning,”
— Dr. Nagendra Boopathy, Cardiologist, Chennai

📌 Policy Implications for India

Update Clinical Guidelines: India’s standard treatment protocols must reflect this evidence.
Public Health Campaigns: Educate both doctors and patients about combination therapies.
Affordable Access: Ensure that single-pill dual drug combinations are available in government schemes like Jan Aushadhi.
Strengthen Screening: Prioritize hypertension screening in Ayushman Bharat Health & Wellness Centres.

📖 Sample UPSC Mains Practice Question

Q. Despite multiple national programs, hypertension remains poorly controlled in India. Discuss the structural and behavioural causes of this issue. How can India improve the efficacy of hypertension management at the primary healthcare level? (250 words)

📊 Key Data for Mains/Essay

1 in 3 Indian adults suffers from hypertension
<20% have their BP under control
High BP is linked to 57% of stroke deaths and 24% of heart disease deaths in India
Combination therapies reduce BP more effectively than single-drug escalation

🩹 Final Word from Suryavanshi IAS

“The battle against hypertension cannot be won with outdated methods and Western models alone. India needs context-specific, evidence-based interventions, and this study sets a new direction for how we treat one of our deadliest health challenges.”
