IBTROZI vs NALFON
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
IBTROZI is a Fabry disease therapeutic, a recombinant human alpha-galactosidase A enzyme that catalyzes the hydrolysis of globotriaosylceramide (GL-3) to reduce its accumulation in tissues.
Fenoprofen, a propionic acid derivative, nonselectively inhibits cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2), reducing prostaglandin synthesis.
150 mg orally twice daily for 4 weeks, followed by 100 mg orally twice daily for 2 weeks, with food.
NALFON (fenoprofen) 200-600 mg orally 3-4 times daily; maximum dose 3200 mg/day.

Terminal elimination half-life is 12–14 hours in patients with normal renal function; prolonged to 24–36 hours in moderate renal impairment (CrCl <60 mL/min), requiring dose adjustment
3-4 hours (terminal half-life in healthy adults; prolonged in elderly and hepatic impairment).
Approximately 70% renal (unchanged drug), 20% biliary/fecal (conjugates and metabolites), 10% other
Renal: 90% (mostly as glucuronide conjugates and unchanged drug; unchanged drug ~1-5%); Fecal: <5%; Biliary: negligible.
