ARB·Cardiovascular - Antihypertensives

Hypertension, Heart Failure, Diabetic nephropathy

PBSARBAtacand32 mg tabletS4+1

Max Dose

32 mg/day

Half-life

9 h

Dry Cough

SAFE

Hyperkalemia

HIGH RISK

Rapid Summary

Overview

Angiotensin II Receptor Blocker (ARB). The direct alternative to ACE inhibitors. Provides identical cardiovascular and renal protection without causing the bradykinin-mediated dry cough.

Maximum Dose

Max 32 mg/day.

Clinical Focus

Carries the exact same risk of hyperkalemia, renal failure (Triple Whammy), and fetal toxicity as ACE inhibitors.

Bottom Line

Candesartan is the ideal ACE inhibitor substitute (no cough) with unique migraine prophylaxis evidence, but carries identical renal and pregnancy risks to ACEis.

Formulation & Access

Brand Names

Atacand

Oral Routes

Tablets (4, 8, 16, 32 mg).

Prescribing & PBS

Unrestricted General Benefit (S4).

Indications & Use

Primary

PBSTGA

Hypertension, Heart Failure, Diabetic nephropathy.

Clinical Place

First-line substitute for patients who develop an ACE-inhibitor cough. Identical efficacy in heart failure.

Quick reference

Class & Role

ARB — Angiotensin II Receptor Blocker (ARB).

Route / Formulation

Tablets (4, 8, 16, 32 mg). (Atacand)

Usual Dose & Max

Start PO 8-16 mg OD. Max 32 mg/day.

Key Indication Doses

Hypertension: Start PO 8-16 mg OD. Max 32 mg/day. Heart Failure (HFrEF): Start PO 4 mg OD. Titrate doubling the dose every 2 weeks to target 32 mg OD. Renal Impairment: Start at 4 mg OD if eGFR < 30. Monitor K+.

Best Uses

Candesartan is the ideal ACE inhibitor substitute (no cough) with unique migraine prophylaxis evidence, but carries identical renal and pregnancy risks to ACEis.

Avoid / Cautions

Bilateral renal artery stenosis, severe hepatic impairment/cholestasis. Pregnancy Category D. Causes fetal renal failure/death.

Key Risks

Renal: Hyperkalemia, AKI in volume-depleted patients. Cardiovascular: Orthostatic hypotension, dizziness. Respiratory: Incidence of dry cough is equivalent to placebo.

Key Interactions

ARB + Diuretic + NSAID (Guaranteed AKI). Additive hyperkalemia with Spironolactone or Trimethoprim.

Monitoring

Check U&E 1-2 weeks post-initiation. Check BP.

Clinical Pearl

Candesartan has strong, unique evidence for Migraine Prophylaxis (off-label). It is frequently prescribed by neurologists to prevent chronic migraines while simultaneously treating the patient's blood pressure.
