CHLORAPREP WITH TINT vs ORAQIX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Chlorhexidine gluconate disrupts microbial cell membranes and precipitates cytoplasmic contents, providing rapid bactericidal activity against gram-positive and gram-negative bacteria. Isopropyl alcohol denatures proteins and disrupts cell membranes, enhancing antimicrobial activity.
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 applicator; allow to dry for at least 3 minutes or until dry; do not use on open wounds or mucous membranes.
750 mg orally once daily for 5 days; or 250 mg orally once daily for 5 days (levofloxacin equivalent).

Chlorhexidine is rapidly eliminated from plasma after IV administration with a terminal half-life of 2-5 hours due to extensive tissue distribution; for topical use, half-life is not clinically relevant as drug acts locally without significant systemic levels.
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.
CHLORAPREP WITH TINT (2% chlorhexidine gluconate and 70% isopropyl alcohol) is a topical antiseptic; systemic absorption is negligible. Renal excretion of absorbed chlorhexidine is minimal (<1% of dose). Biliary/fecal elimination accounts for ~90% of absorbed dose as unchanged drug or metabolites. >90% of topical dose remains on skin.
Renal: ~60% unchanged; biliary/fecal: ~30% as metabolites and parent drug; total clearance approximates renal clearance.
