Mechanism Of Interaction
Inhibition of CYP3A4-mediated metabolism of cilostazol
Literature Reports
A) Coadministration of ketoconazole 400 mg and cilostazol 100 mg increased cilostazol AUC by 117% and Cmax by 94% .
B) Coadministration of erythromycin and cilostazol increased cilostazol AUC by 72% and Cmax by 47%, and increased the AUC of the 4`-trans-hydroxy-cilostazol metabolite by 141% .
C) Coadministration of diltiazem and cilostazol increased cilostazol AUC by roughly 40% and Cmax by roughly 30%, and decreased the clearance of cilostazol by roughly 30% .
Ceritinib Overview
-
Ceritinib is used to treat a certain type of non-small cell lung cancer (NSCLC) that has spread to other parts of the body. Ceritinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of cancer cells.
Cilostazol Overview
-
Cilostazol is used to reduce the symptoms of intermittent claudication (pain in the legs that worsens when walking and improves when resting that is caused by narrowing of the blood vessels that supply blood to the legs). Cilostazol is in a class of medications called platelet-aggregation inhibitors (antiplatelet medications). It works by improving blood flow to the legs.

Severity Categories
Contraindicated
These drugs, generally, should not be used together simultaneously due to the high risk of severe adverse effects. Combining these medications can lead to dangerous health outcomes and should be strictly avoided unless otherwise instructed by your provider.
Major
This interaction could result in very serious and potentially life-threatening consequences. If you are taking this drug combination, it is very important to be under close medical supervision to minimize severe side effects and ensure your safety. It may be necessary to change a medication or dosage to prevent harm.
Moderate

Delayed: Onset of drug interaction typically occurs more than 24 hours after co-administration.
Evidence
Level of documentation of the interaction.
Established: The interaction is documented and substantiated in peer-reviewed medical literature.
Theoretical: This interaction is not fully supported by current medical evidence or well-documented sources, but it is based on known drug mechanisms, drug effects, and other relevant information.
