CHLORAPREP SINGLE SWABSTICK vs PRE-OP
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.
PRE-OP (atropine sulfate and pralidoxime chloride) is a combination anticholinergic and acetylcholinesterase reactivator. Atropine blocks muscarinic acetylcholine receptors to counter cholinergic crisis. Pralidoxime reactivates inhibited acetylcholinesterase by cleaving the phosphate-ester bond formed with organophosphate nerve agents.
Apply topically to intact skin as a single use swabstick. Allow to dry for 3 minutes. No frequency specified for single application.
50 mg intramuscularly or intravenously 45-60 minutes before surgery.

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: 2.5-3.5 hours in normal renal function; prolonged to 8-12 hours in severe renal impairment (CrCl <30 mL/min).
Renal (minimal, <1% as unchanged drug); fecal/biliary (not significant); primarily metabolized to p-chloroaniline and subsequently excreted as conjugates in urine.
Renal: 70-80% as unchanged drug and active metabolites; biliary: 15-20% as metabolites; fecal: <5%.
