Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Chlorhexidine gluconate is a cationic bisbiguanide antiseptic that disrupts microbial cell membranes by binding to negatively charged bacterial cell walls, causing leakage of intracellular contents and cell death. It has broad-spectrum activity against gram-positive and gram-negative bacteria, fungi, and some viruses.
Inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing addition of amino acids to the growing peptide chain. Bacteriostatic.
1-2 mg IV/IM every 4-6 hours as needed for anxiety, up to 10 mg/day.
100 mg orally or intravenously every 12 hours on day 1, then 100 mg once daily; severe infections: 100 mg every 12 hours.

2-4 hours; prolonged in renal impairment (up to 10-12 hours in anuria).
Terminal elimination half-life is 16-18 hours in patients with normal renal function. Prolonged to 20-36 hours in severe renal impairment; no significant change in hepatic impairment.
Primarily renal (70-80% unchanged) with minor biliary excretion (<5%) and fecal elimination (<5%).
Approximately 40% excreted unchanged in urine via glomerular filtration; 20-25% eliminated in feces via biliary secretion; remainder metabolized. Renal clearance is about 30 mL/min.
