ATRIDOX vs DOXYCHEL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ATRIDOX (doxycycline hyclate) is a tetracycline antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing aminoacyl-tRNA from binding to the A site. It also exhibits anti-inflammatory effects by inhibiting matrix metalloproteinases (MMPs) and reducing cytokine production.
Doxycycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing aminoacyl-tRNA from binding to the mRNA-ribosome complex.
50 mg subgingival controlled-release insert applied by dental professional into periodontal pockets once every 3 months.
100 mg orally or intravenously every 12 hours on day 1, then 100 mg once daily. For severe infections, continue 100 mg every 12 hours.

Terminal half-life 16-18 hours; prolonged to 24-48 hours in renal impairment, requiring dose adjustment.
12-22 hours (mean ~16 hours); prolonged in severe hepatic impairment (up to 30 hours).
Primarily renal (60-70% unchanged), biliary/fecal (10-15%) as active drug and metabolites; remainder metabolized.
Renal (20-30%), biliary/fecal (40-60%), with significant enterohepatic circulation; nonrenal elimination accounts for about 70%.
