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