AEMCOLO vs ORBACTIV
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.
Oritavancin is a lipoglycopeptide antibiotic that inhibits bacterial cell wall synthesis by binding to the D-alanyl-D-alanine terminus of the peptidoglycan precursor, disrupting transglycosylation and transpeptidation. It also disrupts bacterial membrane integrity and causes depolarization, leading to cell death.
AEMCOLO (rifamycin) delayed-release tablets: 600 mg orally twice daily for 3 days. Take with or without food.
1200 mg IV once daily for 3 days

Terminal elimination half-life is approximately 18-22 hours, supporting once-daily dosing for maintained intraluminal concentrations.
Terminal elimination half-life is approximately 15.1 hours in healthy adults; in patients with renal impairment, half-life is prolonged (up to 28 hours in severe renal impairment).
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 renal excretion as unchanged drug (approximately 33% of administered dose) and via biliary/fecal elimination (~50% recovered in feces as parent drug and metabolites).
