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 tRNA-amino acid binding. It also exhibits anti-inflammatory effects by inhibiting matrix metalloproteinases and downregulating cytokine production.
Tetracycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing the attachment of aminoacyl-tRNA to the mRNA-ribosome complex.
40 mg orally once daily in the morning, on an empty stomach, at least 1 hour before or 2 hours after meals.
500 mg orally once daily for 28 days; for severe infections, 500 mg twice daily for 14 days.

Terminal elimination half-life is 18–22 hours in patients with normal renal function; prolonged in renal impairment (up to 44 hours in severe dysfunction), necessitating dose adjustment for CrCl <30 mL/min.
6-11 hours (prolonged in renal impairment; up to 57 hours in anuria).
Primarily renal, with about 60% of a dose excreted unchanged in urine via glomerular filtration; biliary/fecal excretion accounts for approximately 35% as active drug and conjugates.
Renal 60% (glomerular filtration), fecal 40% (biliary excretion of active drug and metabolites).
