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 the attachment of aminoacyl-tRNA to the mRNA-ribosome complex. It also exhibits anti-inflammatory and anti-collagenase activities.
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 every 12 hours or 50 mg every 6 hours.
1-2 tablets (200-400 mg chlorhexidine gluconate) sublingually every 6 hours as needed for symptom relief.
