概要
Butabarbital is a barbiturate that induces CYP3A4. Strong CYP3A inducers markedly lower lorlatinib exposure and caused liver enzyme elevations in a study with rifampin, so efficacy may be lost.
この相互作用をわかりやすく説明すると
Butabarbital and Lorlatinib 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.
なぜ起こるのか
Induction of CYP3A4 increases lorlatinib metabolism and lowers its plasma concentrations.
対処法
Avoid the combination and use a non-inducing sedative. Allow the inducer to wash out before starting lorlatinib.
