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 and disinfectant that disrupts microbial cell membranes, causing leakage of cytoplasmic contents and cell death.
100 mg orally or intravenously every 12 hours on day 1, then 100 mg daily.
1-2 tablets (200-400 mg chlorhexidine gluconate) sublingually every 6 hours as needed for symptom relief.
