ARB doses: compare at % of maximum
There is no validated milligram-for-milligram conversion between ARBs such as losartan and valsartan; the evidence compares them at the same percentage of each drug's maximum licensed dose, so this page refuses a fixed ratio and shows the %-of-max basis — educational only, not a prescription.
Licensed maximum dose, by drug
No validated milligram-for-milligram conversion exists between ARBs; this table shows each drug's maximum licensed dose, the basis for comparing them at the same % of maximum. Losartan is the class outlier — weaker per dose with poorer 24-hour once-daily coverage — so an equal % of maximum does not make it equivalent to the others. Educational only, not a prescription.
| Drug | Licensed maximum |
|---|---|
| Losartan | 100 mg |
| Valsartan | 320 mg |
| Telmisartan | 80 mg |
| Olmesartan | 40 mg |
| Candesartan | 32 mg |
| Irbesartan | 300 mg |
Comparing two ARBs
Losartan to Valsartan
There is no validated milligram-for-milligram conversion between Losartan and Valsartan; compare them at the same percentage of each drug's maximum licensed dose instead. Educational only, not a prescription.
Valsartan to Telmisartan
There is no validated milligram-for-milligram conversion between Valsartan and Telmisartan; compare them at the same percentage of each drug's maximum licensed dose instead. Educational only, not a prescription.
