CHG SCRUB vs PRE-OP
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Chlorhexidine gluconate disrupts bacterial cell membranes, leading to leakage of intracellular contents and cell death. It also binds to proteins and inhibits bacterial enzymes.
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 5 mL to wet skin, scrub for 2 minutes, rinse thoroughly. Use undiluted.
50 mg intramuscularly or intravenously 45-60 minutes before surgery.

Approximately 2 hours (terminal); prolonged in renal impairment.
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).
Primarily renal (90% unchanged); <5% biliary/fecal.
Renal: 70-80% as unchanged drug and active metabolites; biliary: 15-20% as metabolites; fecal: <5%.
