Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Doxycycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing aminoacyl-tRNA from binding to the mRNA-ribosome complex, and thus inhibiting peptide chain elongation. It is bacteriostatic and active against a broad range of gram-positive and gram-negative bacteria, as well as atypical organisms.
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.
200 mg orally once daily or 100 mg orally every 12 hours.
1-2 mg IV/IM every 4-6 hours as needed for anxiety, up to 10 mg/day.

Terminal elimination half-life: 18–22 hours in adults with normal renal function; prolonged in renal impairment (up to 40 hours).
2-4 hours; prolonged in renal impairment (up to 10-12 hours in anuria).
Renal: 40% unchanged via glomerular filtration; Biliary/fecal: 20–25% as active drug and metabolites; remainder as inactive metabolites.
Primarily renal (70-80% unchanged) with minor biliary excretion (<5%) and fecal elimination (<5%).
