Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Doxycycline, a tetracycline antibiotic, inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, blocking aminoacyl-tRNA binding to the mRNA-ribosome complex.
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.
100 mg orally twice daily on day 1, then 100 mg once daily; alternatively, 200 mg orally once daily.
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 25–30 hours) or with hepatic dysfunction.
2-4 hours; prolonged in renal impairment (up to 10-12 hours in anuria).
Renal (approximately 40% as unchanged drug via glomerular filtration), fecal/biliary (up to 30% as conjugated or inactive metabolites), remainder metabolized.
Primarily renal (70-80% unchanged) with minor biliary excretion (<5%) and fecal elimination (<5%).
