Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Reversible tyrosine kinase inhibitor that inhibits ErbB-1 (EGFR) and ErbB-2 (HER2) by binding to the ATP-binding pocket, preventing receptor autophosphorylation and downstream signaling.
Lenvatinib is a multikinase inhibitor that targets vascular endothelial growth factor receptors (VEGFR1, VEGFR2, VEGFR3), fibroblast growth factor receptors (FGFR1, FGFR2, FGFR3, FGFR4), platelet-derived growth factor receptor alpha (PDGFRα), KIT, and RET. It inhibits angiogenesis, tumor growth, and progression by blocking these receptor tyrosine kinases.
Lapatinib ditosylate 1250 mg orally once daily on days 1-21 continuously, plus capecitabine 2000 mg/m2 orally once daily in 2 divided doses on days 1-14 of a 21-day cycle. Alternatively, 1500 mg orally once daily with letrozole 2.5 mg orally once daily continuously.
24 mg orally once daily for differentiated thyroid carcinoma; 18 mg orally once daily plus everolimus 5 mg orally once daily for renal cell carcinoma; 12 mg orally once daily plus pembrolizumab 200 mg intravenously every 3 weeks for endometrial carcinoma; 8 mg orally once daily (or 10 mg for patients with body weight ≥60 kg) plus pembrolizumab 200 mg intravenously every 3 weeks for hepatocellular carcinoma.

Terminal elimination half-life is 14–24 hours; after repeated dosing, effective half-life is ~24 hours clinically.
Terminal elimination half-life is approximately 28 hours, supporting once-daily dosing.
Fecal (approximately 87% as metabolites, with 3% as parent drug); renal (approximately 3% as metabolites).
Approximately 71% of the dose is excreted in feces (34% as unchanged drug) and 25% in urine (0.4% as unchanged).
