Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Minocycline is a semisynthetic tetracycline antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing the addition of amino acids to the elongating peptide chain. This action is bacteriostatic. In periodontal disease, it also inhibits matrix metalloproteinases (MMPs), particularly collagenase, and suppresses inflammatory cytokine production, reducing tissue destruction.
Tetracycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing the attachment of aminoacyl-tRNA to the mRNA-ribosome complex.
1 mg subgingival application per periodontal pocket, applied as a single dose by a dental professional.
500 mg orally once daily for 28 days; for severe infections, 500 mg twice daily for 14 days.

The terminal elimination half-life of minocycline is 11-17 hours (mean ~16 hours). This long half-life allows for twice-daily dosing in systemic use, but for Arestin (subgingival), local sustained release provides prolonged local exposure.
6-11 hours (prolonged in renal impairment; up to 57 hours in anuria).
Minocycline is primarily eliminated via hepatic metabolism and biliary/fecal excretion. Renal excretion accounts for approximately 10-20% of the dose, with the remainder excreted in feces via bile. Less than 10% is recovered unchanged in urine.
Renal 60% (glomerular filtration), fecal 40% (biliary excretion of active drug and metabolites).
