CHLOROFAIR vs ORAQIX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Chloramphenicol inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit, preventing peptide bond formation.
Oraqix is a eutectic mixture of lidocaine and prilocaine that acts as a local anesthetic. It reversibly blocks sodium ion channels in nerve cell membranes, inhibiting the initiation and conduction of nerve impulses, thereby producing anesthesia.
125 mg IV every 6 hours for 10 days.
750 mg orally once daily for 5 days; or 250 mg orally once daily for 5 days (levofloxacin equivalent).

4.5 hours (prolonged to 10–12 hours in renal impairment)
Terminal elimination half-life: 7.5 hours (range 6-9 h) in patients with normal renal function; extends to 20-30 h in severe renal impairment (CrCl <30 mL/min), necessitating dose adjustment.
Renal: 70% unchanged; hepatic metabolism: 25% conjugated; fecal: 5%
Renal: ~60% unchanged; biliary/fecal: ~30% as metabolites and parent drug; total clearance approximates renal clearance.
