Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Oxytetracycline binds reversibly to the 30S ribosomal subunit, inhibiting protein synthesis by blocking the attachment of aminoacyl-tRNA to the mRNA-ribosome complex.
Solodyn (minocycline hydrochloride) is a tetracycline antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing the addition of amino acids to the growing peptide chain.
250-500 mg orally every 6 hours or 1-2 g/day divided every 12 hours intravenously.
1 mg/kg orally once daily as extended-release tablets; not to exceed 100 mg/day. Alternatively, 1 mg/kg orally once daily as immediate-release tablets; not to exceed 100 mg/day.

6-10 hours (prolonged to 48-100 hours in renal impairment; consider dose adjustment in CrCl <50 mL/min)
Terminal elimination half-life: 11-22 hours (mean ~16 hours). Clinically, steady-state reached in 3-4 days; half-life prolonged in renal impairment.
Renal (60-70% unchanged by glomerular filtration); biliary/fecal (20-35%)
Primarily renal (40-70% unchanged) via glomerular filtration; significant biliary/fecal (20-30%) as unchanged drug and metabolites. Enterohepatic recirculation occurs.
