摘要
Cholestyramine binds teriflunomide in the gut and interrupts its enterohepatic recirculation, causing a marked fall in plasma levels. This is exploited for rapid elimination after leflunomide toxicity, but unintended use reduces efficacy.
用白話說明這項交互作用的意義
Cholestyramine and Leflunomide can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Cholestyramine belongs to Cardiovascular; Leflunomide belongs to Musculoskeletal.
為什麼會發生
Cholestyramine binds teriflunomide in the intestine, preventing reabsorption and enhancing fecal elimination.
處置方式
Avoid concurrent use unless a washout is intended; for accelerated elimination, use the labeled cholestyramine regimen. Otherwise choose another lipid-lowering agent.
