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 aminoacyl-tRNA from binding to the mRNA-ribosome complex, and thus inhibiting peptide chain elongation. It is bacteriostatic and active against a broad range of gram-positive and gram-negative bacteria, as well as atypical organisms.
Minocycline is a tetracycline antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, blocking the binding of aminoacyl-tRNA to the mRNA-ribosome complex.
200 mg orally once daily or 100 mg orally every 12 hours.
100 mg orally or intravenously every 12 hours for 24 hours, then 100 mg every 12 hours; severe infections: 200 mg initially, then 100 mg every 12 hours.

Terminal elimination half-life: 18–22 hours in adults with normal renal function; prolonged in renal impairment (up to 40 hours).
Terminal elimination half-life is 11–17 hours in patients with normal renal function; prolonged up to 18–69 hours in renal impairment.
Renal: 40% unchanged via glomerular filtration; Biliary/fecal: 20–25% as active drug and metabolites; remainder as inactive metabolites.
Primarily renal (approximately 70% unchanged) and biliary/fecal (approximately 30%, with enterohepatic recycling).
