Thận trọng
Patients w/ history of CV events (e.g. heart failure, cardiomyopathy, MI, myocardial ischaemia); history of QT interval prolongation; bradycardia, electrolyte imbalance, thyroid dysfunction, underlying or poorly controlled HTN. Patient undergoing major surgery. Hepatic and renal impairment. Pregnancy. Concomitant use w/ potent CYP3A4 enzyme inhibitors and inducers should be avoided, if not possible, consider dosage adjustment.
Monitor LVEF, BP, ECG, adrenal function, CBC w/ differential and platelet, LFTs (prior to and during each cycle of treatment), blood glucose levels, urinalysis, serum chemistries (e.g. Mg, phosphate, K); signs/symptoms of hypoglycaemia, hypothyroidism, hyperthyroidism, or thyroiditis.
Quá liều
Symptoms: Impaired muscle coordination, head shakes, hypoactivity, piloerection, ocular discharge, GI distress. Management: General supportive treatment. Emesis or gastric lavage may be considered to eliminate unabsorbed drug.
Description: Mechanism of Action: Sunitinib inhibits signal transduction pathways involving multiple receptor tyrosine kinases which are implicated in tumour growth, pathologic angiogenesis and metastatic progression of cancer, including platelet-derived growth factor receptors (i.e. PDGFR-α, PDGFR-β), vascular endothelial growth factor receptors (i.e. VEGFR-1, VEGFR-2, VEGFR-3), stem cell factor receptor (i.e. c-Kit), fms-like tyrosine kinase-3 (Flt-3), colony-stimulating factor receptor type 1 (CSF-1R), and the glial cell-line-derived neurotrophic factor receptor (RET). Pharmacokinetics: Absorption: Time to peak plasma concentration: 6-12 hr. Distribution: Volume of distribution: 2,230 L. Plasma protein binding: Approx 95% (sunitinib); approx 90% (N-desmethyl metabolite). Metabolism: Metabolised mainly by CYP3A4 enzyme to the primary active N-desmethyl metabolite. Excretion: Mainly via faeces (approx 61%); urine (approx 16%, as unchanged drug and as N-desmethyl metabolite). Terminal elimination half-life: 40-60 hr (sunitinib); 80-110 hr (N-desmethyl metabolite).
