GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of ivacaftor. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit.
ADJUST DOSING INTERVAL: According to the manufacturer, systemic exposure to ivacaftor increased approximately 2.5- to 4-fold and systemic exposure to lumacaftor increased approximately 2-fold following administration with fat-containing foods relative to administration in a fasting state. Tezacaftor exposure is not affected by administration of fat-containing foods.
MANAGEMENT: Patients treated with ivacaftor should avoid consumption of grapefruit juice and any food that contains grapefruit or Seville oranges. Ivacaftor, lumacaftor/ivacaftor, and tezacaftor/ivacaftor should all be administered with fat-containing foods such as eggs, avocados, nuts, butter, peanut butter, cheese pizza, and whole-milk dairy products. A typical cystic fibrosis diet will satisfy this requirement.
