Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
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.
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.
40 mg orally once daily in the morning, on an empty stomach, at least 1 hour before or 2 hours after meals.

Terminal elimination half-life is 11–17 hours in patients with normal renal function; prolonged up to 18–69 hours in renal impairment.
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.
Primarily renal (approximately 70% unchanged) and biliary/fecal (approximately 30%, with enterohepatic recycling).
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.
