摘要
Phenobarbital can induce HMG-CoA reductase and bile acid synthesis, which may counteract the intended suppression of abnormal bile acid production by chenodeoxycholic acid. Therapeutic effect may be reduced.
用白話說明這項交互作用的意義
Chenodeoxycholic acid and Phenobarbitone can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Chenodeoxycholic acid belongs to Gastrointestinal Tract; Phenobarbitone belongs to Central Nervous System.
為什麼會發生
Enzyme induction by phenobarbital increases cholesterol and bile acid synthesis, opposing chenodeoxycholic acid feedback inhibition.
處置方式
Monitor urinary or serum bile alcohols and adjust the chenodeoxycholic acid dose as needed. Consider a non-inducing anticonvulsant if appropriate.
