摘要
Phenobarbital is expected to reduce cabotegravir exposure to subtherapeutic levels. This risks virologic failure and resistance, especially with long-acting formulations that cannot be quickly adjusted.
用白話說明這項交互作用的意義
Cabotegravir and Phenobarbitone 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.
Cabotegravir belongs to Anti Virals; Phenobarbitone belongs to Central Nervous System.
為什麼會發生
Phenobarbital induces UGT1A1 and other metabolic enzymes, increasing cabotegravir clearance.
處置方式
Avoid the combination and use an alternative anticonvulsant or antiretroviral. Account for prolonged induction after phenobarbital is discontinued.
