Ratings come from the documented interaction literature and are reviewed by a pharmacist. They describe the documented risk of the combination, not what will necessarily happen to you — your dose, timing, and health picture all matter.
What happens
Increased rosuvastatin exposure and an increased risk of rosuvastatin-related adverse effects
Interaction Deep Dive
Avoid coadministration of asciminib (BCRP inhibitor) and rosuvastatin (BCRP substrate) at all recommended doses as it may increase rosuvastatin exposure, which may increase the risk of adverse reactions of rosuvastatin. Closely monitor for adverse reactions in patients treated with asciminib at all recommended doses with concomitant use of BCRP substrates. Reduce the dosage of BCRP substrate as recommended when used concomitantly with asciminib at all recommended doses1.
Why it happens (mechanism)
Inhibition of BCRP-mediated efflux transport of rosuvastatin
