摘要
Phenobarbital may interfere with folate-dependent pathways that support tetrahydrobiopterin (BH4) availability. This could reduce sapropterin effect and allow blood phenylalanine to rise in patients with phenylketonuria.
用白話說明這項交互作用的意義
Phenobarbitone and Sapropterin 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.
Phenobarbitone belongs to Central Nervous System; Sapropterin belongs to Miscellaneous.
為什麼會發生
Interference with folate metabolism may lower BH4 availability, though the mechanism is not firmly established for phenobarbital.
