Interaction:

Drugs

FIuconazole: Decreased conversion to active metabolite (CYP2C9 inhibition), loss of antihypertensive effects

Lithium: Increased renal lithium reabsorption at the proximal tubular site due to the natriuresis associated with the inhibition of aldosterone secretion; increased risk of lithium toxicity

Rifampin: Induced metabolism of losartan and metabolite, resulting in a decrease in the area under the concentration-time curve (AUC) and half-life of both compounds and reduced losartan efficacy
