摘要
Primidone is metabolized to phenobarbital and acts as a strong CYP3A4 inducer, which can lower lorlatinib concentrations and risk treatment failure. Strong inducers are contraindicated with lorlatinib, and hepatotoxicity has been seen with this type of combination.
用白話說明這項交互作用的意義
Lorlatinib and Primidone 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.
Lorlatinib belongs to Oncology; Primidone belongs to Central Nervous System.
為什麼會發生
Induction of CYP3A4 by primidone and its phenobarbital metabolite accelerates lorlatinib metabolism.
處置方式
Do not co-administer; switch to a non-inducing anticonvulsant. Allow washout of about 3 half-lives of the inducer before starting lorlatinib.
