AEMCOLO vs KETEK
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
AEMCOLO (crizotinib) is a tyrosine kinase inhibitor that targets anaplastic lymphoma kinase (ALK), c-ros oncogene 1 (ROS1), and mesenchymal-epithelial transition factor (MET). It inhibits ALK and ROS1 phosphorylation, blocking downstream signaling pathways involved in cell proliferation and survival.
Telithromycin binds to the 50S subunit of bacterial ribosome, inhibiting protein synthesis by blocking peptide chain elongation.
AEMCOLO (rifamycin) delayed-release tablets: 600 mg orally twice daily for 3 days. Take with or without food.
Telithromycin 800 mg orally once daily for 7-10 days.

Terminal elimination half-life is approximately 18-22 hours, supporting once-daily dosing for maintained intraluminal concentrations.
Terminal half-life (t½) is 9.8–10.6 hours in young healthy adults, allowing once-daily dosing. In elderly or severe hepatic impairment, t½ may be prolonged.
Primarily fecal elimination as unchanged drug; approximately 90% of a dose is recovered in feces, with less than 1% excreted unchanged in urine. Biliary excretion accounts for the remainder.
Primarily fecal (≈70%) via biliary excretion of unchanged drug; renal excretion accounts for ≈13% (mostly unchanged), with additional minor metabolism (<30%).
