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