Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Doxycycline inhibits bacterial protein synthesis by reversibly binding to the 30S ribosomal subunit, preventing the addition of amino acids to the growing peptide chain. It also exhibits anti-inflammatory effects by inhibiting matrix metalloproteinases and reducing cytokine production.
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 or intravenously every 12 hours on day 1, then 100 mg daily.
1-2 mg IV/IM every 4-6 hours as needed for anxiety, up to 10 mg/day.

Terminal elimination half-life is 18-22 hours in adults; prolonged to 20-30 hours in renal impairment.
2-4 hours; prolonged in renal impairment (up to 10-12 hours in anuria).
Renal (approximately 40% as unchanged drug) and fecal/biliary (approximately 50-60% as inactive metabolites and unchanged drug).
Primarily renal (70-80% unchanged) with minor biliary excretion (<5%) and fecal elimination (<5%).
