CHLORAPREP SINGLE SWABSTICK vs ORAQIX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Chlorhexidine gluconate, a bisbiguanide antiseptic, disrupts microbial cell membranes and precipitates cytoplasmic contents at bactericidal concentrations.
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.
Apply topically to intact skin as a single use swabstick. Allow to dry for 3 minutes. No frequency specified for single application.
750 mg orally once daily for 5 days; or 250 mg orally once daily for 5 days (levofloxacin equivalent).

Chlorhexidine: terminal half-life approximately 3-5 hours after cutaneous application; prolonged with repeated use due to dermal reservoir effect. p-Chloroaniline: terminal half-life 10-12 hours.
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 (minimal, <1% as unchanged drug); fecal/biliary (not significant); primarily metabolized to p-chloroaniline and subsequently excreted as conjugates in urine.
Renal: ~60% unchanged; biliary/fecal: ~30% as metabolites and parent drug; total clearance approximates renal clearance.
