Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Tetracycline antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing aminoacyl-tRNA from binding to the A site.
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.
Topical application of tetracycline hydrochloride 10 mg/g periodontal fiber. Inserted into periodontal pocket and left in place for 10 days.
100 mg orally or intravenously every 12 hours on day 1, then 100 mg daily.

Not applicable due to local degradation; systemic half-life is negligible as tetracycline hydrochloride is not absorbed.
Terminal elimination half-life is 18-22 hours in adults; prolonged to 20-30 hours in renal impairment.
Primarily eliminated by phagocytic degradation at the application site; minimal systemic absorption, negligible renal or biliary excretion.
Renal (approximately 40% as unchanged drug) and fecal/biliary (approximately 50-60% as inactive metabolites and unchanged drug).
