摘要
Ertapenem markedly lowers serum valproic acid concentrations, which can fall below the therapeutic range within a day or two. This can cause loss of seizure control, and the reduction may persist after the antibiotic is discontinued.
用白話說明這項交互作用的意義
Ertapenem and Valproic acid 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.
Ertapenem belongs to Anti Bacterial; Valproic acid belongs to Central Nervous System.
為什麼會發生
Carbapenems are thought to inhibit hydrolysis of valproate glucuronide back to valproate and may reduce its absorption and red cell uptake, lowering valproate concentrations.
處置方式
Avoid the combination and choose a non-carbapenem antibiotic. If unavoidable, add a different anticonvulsant and monitor valproate levels and seizure activity, including after the antibiotic ends.
