摘要
NSAIDs can reduce renal clearance of pemetrexed, raising its exposure and the risk of myelosuppression, renal toxicity and gastrointestinal toxicity. The risk is greatest in patients with mild to moderate renal impairment. Celecoxib has a relatively long half-life, so the effect can persist.
用白話說明這項交互作用的意義
Celecoxib and Pemetrexed 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.
Celecoxib belongs to Musculoskeletal; Pemetrexed belongs to Oncology.
為什麼會發生
NSAID-induced reduction in renal prostaglandin-dependent perfusion and glomerular filtration decreases renal elimination of pemetrexed.
處置方式
Where possible, hold celecoxib in the days before, on the day of and after pemetrexed, following the labeling schedule for long half-life NSAIDs. If it cannot be avoided, monitor blood counts and renal function closely.
