From the Guidelines
Candesartan 8 mg is equivalent to losartan 50 mg, based on the most recent and highest quality study available 1. The equivalence of candesartan to other angiotensin II receptor blockers (ARBs) can be determined by comparing their target doses.
- The target dose of candesartan is 32 mg once daily, as stated in the 2020 ACC/AHA clinical performance and quality measures for adults with heart failure 1.
- The target dose of losartan is 100 mg once daily, as stated in the same guideline 1.
- However, the 2017 ACC/AHA/AAPA/ABC/ACPM/AGS/APhA/ASH/ASPC/NMA/PCNA guideline for the prevention, detection, evaluation, and management of high blood pressure in adults recommends losartan 50-100 mg once daily 1. Considering the information from the most recent study 1, the equivalent dose of losartan to candesartan 8 mg is 50 mg. It's essential to monitor blood pressure closely when switching between these medications, as individual responses may vary.
- The medications are typically taken once daily, with or without food, though specific timing may vary based on the particular ARB.
- Side effects are generally similar across the class and may include dizziness, headache, and elevated potassium levels. When switching between ARBs, it's crucial to maintain the same monitoring schedule for blood pressure and kidney function that was established with candesartan 1.
From the Research
Equivalent Dose of Candesartan 8 mg
- The equivalent dose of candesartan 8 mg is not directly stated in the provided studies, but comparisons can be made with other medications.
- According to 2, candesartan cilexetil 8 mg was compared to losartan 50 mg, and the results showed that candesartan cilexetil 8 mg had a greater reduction in blood pressure than losartan 50 mg.
- In 3, the study compared the effects of losartan, candesartan, and losartan/hydrochlorothiazide in patients with mild to moderate hypertension, and the results showed that candesartan 8 mg/16 mg was comparable to losartan 50 mg/100 mg in terms of blood pressure reduction.
- The study in 4 compared the efficacy of candesartan cilexetil 8 mg and losartan 50 mg as monotherapy in patients with essential hypertension, and the results showed that candesartan cilexetil 8 mg had a greater reduction in diastolic blood pressure than losartan 50 mg.
- In terms of other medications, 5 mentions that angiotensin receptor blockers, including candesartan, are as effective as other classes of antihypertensive agents, such as angiotensin-converting enzyme inhibitors, calcium antagonists, thiazide diuretics, and beta-blockers.
Comparison with Losartan
- The studies suggest that candesartan 8 mg is comparable to or more effective than losartan 50 mg in reducing blood pressure.
- According to 3, candesartan 8 mg/16 mg was comparable to losartan 50 mg/100 mg in terms of blood pressure reduction.
- In 4, candesartan cilexetil 8 mg had a greater reduction in diastolic blood pressure than losartan 50 mg.
Clinical Practice
- The study in 6 reviews the literature on the role of candesartan-based therapy for hypertension, stroke, diabetes mellitus, and heart failure, and suggests that candesartan is an effective and well-tolerated treatment option.
- According to 5, angiotensin receptor blockers, including candesartan, have an excellent tolerability and side effect profile, making them a desirable treatment option for hypertension.
