PHISOHEX vs PRE-OP
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Disrupts bacterial cell wall synthesis by binding to the bacterial ribosome and inhibiting protein synthesis; also has surfactant properties that disrupt bacterial cell membrane integrity.
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 as a 3% emulsion to affected area, rinse thoroughly; typically used 1-2 times daily for up to 10 days.
50 mg intramuscularly or intravenously 45-60 minutes before surgery.

Terminal elimination half-life approximately 6-7 hours in adults with normal renal function. Prolonged in renal impairment (up to 20 hours) due to reduced clearance of active metabolite (pentachlorophenol).
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 (biliary/fecal negligible). Up to 10% of dose excreted unchanged in urine; remainder as metabolites (glucuronide and sulfate conjugates).
Renal: 70-80% as unchanged drug and active metabolites; biliary: 15-20% as metabolites; fecal: <5%.
