First‑Line Antihypertensive Therapy for Indian Adults

1. Initial Drug Selection for Non‑Black Indian Patients

  • Start with a low‑dose ACE inhibitor or ARB as the preferred first‑line monotherapy in adult Indian patients without specific contraindications (Grade not specified) [1][2][4][5].
  • ARBs show higher treatment persistence than thiazide diuretics or β‑blockers, supporting better long‑term adherence 6.
  • ACE inhibitors and ARBs confer cardiovascular and renal protection that exceeds the effect of blood‑pressure reduction alone [7][5].

2. Stepwise Intensification When Blood‑Pressure Goal Is Not Met

  • If target BP is not achieved, first up‑titrate the ACE inhibitor/ARB to the full approved dose, then add a dihydropyridine CCB [1][2]4.
  • When baseline systolic ≥ 20 mmHg or diastolic ≥ 10 mmHg above target (e.g., SBP ≥ 160 mmHg or DBP ≥ 100 mmHg), initiate a single‑pill combination of ARB + CCB [1][3].
  • If BP remains uncontrolled after the above, add a thiazide or thiazide‑like diuretic as a third agent [1][2]8.

3. Acceptable First‑Line Monotherapy Options

  • Thiazide or thiazide‑like diuretics (chlorthalidone, indapamide) are equally acceptable as initial monotherapy; the longer‑acting agents are preferred over hydrochlorothiazide [7][5]3.
  • Thiazide‑like diuretics are especially effective in isolated systolic hypertension 7.
  • Monitoring for hypokalaemia is required when using thiazide diuretics [7][5].
  • Long‑acting dihydropyridine CCBs (amlodipine, cilnidipine) are also first‑line choices [7][5]3.
  • β‑Blockers should not be used as first‑line therapy in patients aged ≥ 60 years (Grade A recommendation against) [7][5].

5. When to Initiate Combination Therapy (Single‑Pill Preferred)

  • Start a two‑drug single‑pill regimen if any of the following apply:
  • Preferred combination regimens and their evidence grades:

6. Drugs to Avoid as Initial Monotherapy

  • Alpha‑blockers (Grade A recommendation against) [7][5].
  • β‑Blockers in patients ≥ 60 years (Grade A recommendation against) [7][5].
  • ACE inhibitors in Black patients (not directly relevant to the Indian population but noted) [7][5].
  • Never combine an ACE inhibitor with an ARB (Grade A recommendation against) [7][5].

7. Blood‑Pressure Targets and Monitoring

  • General adult population: < 140/90 mmHg (minimum target) [1][3].
  • Optimal target for most patients: < 130/80 mmHg [1][2].
  • High‑risk groups (CVD, CKD, diabetes): < 130/80 mmHg 3.
  • Elderly or frail patients: individualize therapy; aim for at least a 20/10 mmHg reduction [1][2].

8. Follow‑Up and Treatment Timeline

  • Monthly reassessment after therapy initiation or any medication change until the BP target is reached 3.
  • Once BP is controlled, schedule visits every 3–5 months 3.
  • Aim to achieve the target BP within 3 months of starting treatment [1][2].

9. Common Pitfalls and Practical Tips

  • Clinical inertia: most patients require 2–3 agents; avoid persisting with ineffective monotherapy beyond 2–4 weeks [6][5].
  • Dosing strategy: begin with at least half of the maximum recommended dose to reduce the need for multiple titrations 6.
  • Lifestyle measures (salt reduction, weight loss, exercise) should be instituted concurrently with pharmacotherapy 1.
  • Avoid inappropriate drug combinations:
