LAROTID vs POLYMOX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Larotrectinib is a selective inhibitor of tropomyosin receptor kinase (TRK) A, B, and C. It inhibits TRK kinase activity by binding to the ATP-binding site, leading to inhibition of downstream signaling pathways, which results in reduced cell proliferation and tumor growth in tumors with NTRK gene fusions.
Amoxicillin is a bactericidal antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs) and inhibiting transpeptidase activity, leading to cell lysis.
Larotrectinib 100 mg orally twice daily, with or without food, for adult patients.
250-500 mg orally every 8 hours or 500-875 mg orally every 12 hours; maximum 4 g/day.

Terminal elimination half-life = 1-1.5 hours in adults; prolonged in renal impairment (up to 12-20 hours in anuria)
Renal: 70-80% unchanged by glomerular filtration and tubular secretion; Biliary/Fecal: <10% as inactive metabolites.
