摘要
Primidone is metabolized to phenobarbital, which induces CYP3A4 and can lower ranolazine concentrations. Antianginal effect may be lost, and labeling contraindicates CYP3A inducers.
用白話說明這項交互作用的意義
Primidone and Ranolazine 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.

為什麼會發生
CYP3A4 induction by primidone and its metabolite phenobarbital, increasing ranolazine clearance.
處置方式
