With which drugs do ARBs interact?

ARBs have few interactions with other drugs. Since ARBs may increase blood levels of potassium, the use of potassium supplements, salt substitutes (which often contain potassium), or other drugs that increase potassium may result in excessive blood potassium levels and cardiac arrhythmias. ARBs may also increase the blood concentration of lithium (Eskalith) and lead to an increase in side effects from lithium. Rifampin (Rifadin) reduces the blood levels of losartan, and fluconazole (Diflucan) reduces the conversion of losartan to its active form. These effects could decrease the effects of losartan.
