Women of childbearing potential and men with female partners of childbearing potential must use effective birth control methods during treatment and up to 1 month after treatment. Discontinue breastfeeding during treatment and for 2 weeks after the last dose.
Chỉ số theo dõi
Verify pregnancy status of women of childbearing potential before starting treatment. Monitor blood pressure (weekly during the 1st month, at least monthly thereafter and as clinically indicated); LFTs, presence of proteinuria (at baseline and periodically during treatment); INR in patients receiving anticoagulant therapy. Assess for signs and symptoms of dermatologic toxicity, gastrointestinal perforation, bleeding, thromboembolic events, impaired wound healing, infection and posterior reversible encephalopathy syndrome.

May reduce serum concentration and efficacy with moderate or strong CYP3A4 inducers (e.g. rifampicin).
Tác dụng
Description: Mechanism of Action: Fruquintinib, an antineoplastic agent, is a potent, highly selective, small molecule kinase inhibitor of vascular endothelial growth factor receptors (VEGFR)-1, -2 and -3. It inhibits VEGF-mediated endothelial cell proliferation, tubular formation, VEGFR-2 phosphorylation and tumour growth in in vitro and in vivo analyses. Pharmacokinetics: Absorption: Time to peak plasma concentration: Approx 2 hours. Distribution: Volume of distribution: Approx 46 L. Plasma protein binding: Approx 95%. Metabolism: Metabolised in the liver mainly by CYP450 (CYP3A4 and to a lesser extent by CYP2C8, CYP2C9 and CYP2C19 isoenzymes) and via sulfation and glucuronidation. Excretion: Via urine (approx 60%; 0.5% as unchanged drug); faeces (30%; 5% as unchanged drug). Elimination half-life: Approx 42 hours.
