Main therapeutic uses of celecoxib

Drug interactions

6 documented interaction(s) with other medications in this knowledge base.

Celecoxib作为CYP2C9抑制剂,可减少Glibenclamide的代谢,导致其血药浓度升高,增强降糖作用

塞来昔布为中度CYP2D6抑制剂,可减少羟氯喹代谢,升高其血药浓度,增加QT间期延长、视网膜病变及心肌病等毒性风险

LatanoprostMODERATE

NSAIDs(包括COX-2抑制剂)可能通过抑制内源性前列腺素合成而拮抗前列腺素类似物的降眼压作用,从而减弱latanoprost增加葡萄膜巩膜外流的疗效

LiraglutideMODERATE

Liraglutide的胃肠道不良反应可导致脱水/容量不足,从而增强Celecoxib(COX-2抑制剂)对肾前列腺素的抑制,增加急性肾损伤风险

MethotrexateMODERATE

NSAIDs(包括COX-2抑制剂)可通过抑制前列腺素减少肾血流量/GFR,并竞争肾小管分泌,从而降低甲氨蝶呤肾清除率,升高其血药浓度并增加毒性风险(骨髓抑制、黏膜炎、肝肾毒性)。Celecoxib对低剂量MTX的药代动力学影响相对较小,但仍属同类风险。

两者均可增加血栓形成风险(COX-2抑制剂抑制前列环素产生促血栓效应;复方口服避孕药升高凝血因子并降低抗凝血酶),合用可能产生叠加的静脉/动脉血栓栓塞风险
