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.
Doxycycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, blocking the attachment of aminoacyl-tRNA to the mRNA-ribosome complex.
1-2 mg IV/IM every 4-6 hours as needed for anxiety, up to 10 mg/day.
100 mg orally or IV every 12 hours on day 1, then 100 mg orally or IV every 24 hours; for 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: 14-22 hours (mean ~18 hours) in adults; prolonged up to 24-48 hours in renal impairment; no dose adjustment in mild-moderate renal impairment but caution in severe (CrCl <30 mL/min).
Primarily renal (70-80% unchanged) with minor biliary excretion (<5%) and fecal elimination (<5%).
Renal: ~40% (glomerular filtration, tubular secretion); biliary: ~20-60% (enterohepatic circulation); fecal: ~30% (unabsorbed or excreted in bile).
