ORAQIX vs READYPREP CHG
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Chlorhexidine gluconate disrupts microbial cell membranes, causing leakage of cytoplasmic contents and cell death. Its cationic nature binds to negatively charged bacterial cell walls, providing persistent antimicrobial activity.
750 mg orally once daily for 5 days; or 250 mg orally once daily for 5 days (levofloxacin equivalent).
No standard systemic dosing; used as a 4% chlorhexidine gluconate topical antiseptic solution applied once daily to entire body for preoperative skin preparation or for chlorhexidine bathing in infection prevention protocols.

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.
60 minutes (terminal) in patients with normal renal function; prolonged in renal impairment.
Renal: ~60% unchanged; biliary/fecal: ~30% as metabolites and parent drug; total clearance approximates renal clearance.
Renal: ~100% unchanged via glomerular filtration. No biliary or fecal elimination.
