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.
Tetracycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing the attachment of aminoacyl-tRNA to the A site.
1-2 mg IV/IM every 4-6 hours as needed for anxiety, up to 10 mg/day.
250–500 mg orally every 6 hours; or 500 mg to 1 g intravenously every 6–12 hours (administer slow IV).

2-4 hours; prolonged in renal impairment (up to 10-12 hours in anuria).
Terminal elimination half-life: 6-8 hours in normal renal function; prolonged to 18-30 hours in severe renal impairment (CrCl <30 mL/min); dosing adjustment required.
Primarily renal (70-80% unchanged) with minor biliary excretion (<5%) and fecal elimination (<5%).
Renal (glomerular filtration): 60% unchanged in urine; biliary/fecal: 40% as active drug and metabolites; enterohepatic recirculation occurs.
