AVAGARD vs PRE-OP II
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Avagard (chlorhexidine gluconate 1% and isopropyl alcohol 61%) is an antiseptic with bactericidal activity. Chlorhexidine disrupts cell membranes and precipitates cell contents; isopropyl alcohol denatures proteins and dissolves lipids.
PRE-OP II (glycopyrrolate and neostigmine) reverses neuromuscular blockade by inhibiting acetylcholinesterase via neostigmine, increasing acetylcholine at the neuromuscular junction, while glycopyrrolate, an anticholinergic, mitigates muscarinic side effects.
Chlorhexidine gluconate 2% + isopropyl alcohol 70% solution: apply 5 mL to each hand and forearm, rub vigorously for 2-3 minutes, allow to dry; repeat once. For surgical hand antisepsis: apply 5 mL to hands and forearms, scrub for 3 minutes, rinse, repeat.
1-2 mg/kg IV bolus once preoperatively; maximum dose 100 mg.

Terminal elimination half-life is 4-6 hours in patients with normal renal function; prolonged to 18-24 hours in severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life is 2-4 hours (prolonged in renal impairment; dose adjustment needed for CrCl <30 mL/min)
Primarily renal (unchanged drug and metabolites) with approximately 20-30% excreted fecally; renal clearance accounts for >60% of total clearance.
Renal excretion (98% as unchanged drug), biliary/fecal (<2%)
