Summary
Levoketoconazole is a strong CYP3A4 and P-gp inhibitor and can markedly raise sirolimus exposure. This may cause serious toxicity, including myelosuppression, hyperlipidemia, infection and impaired wound healing.
What this interaction means in plain words
Levoketoconazole and Sirolimus are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Levoketoconazole belongs to Endocrine; Sirolimus belongs to Miscellaneous.
Why it happens
Strong inhibition of CYP3A4 and P-glycoprotein reduces sirolimus metabolism and efflux.
What to do
Avoid the combination and use an alternative treatment. If the interaction cannot be avoided, specialist guidance and very close sirolimus level monitoring are needed.
