Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing addition of amino acids to the growing peptide chain. Bacteriostatic.
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.
100 mg orally or intravenously every 12 hours on day 1, then 100 mg once daily; severe infections: 100 mg every 12 hours.

Terminal elimination half-life: 11-22 hours (mean ~16 hours). Clinically, steady-state reached in 3-4 days; half-life prolonged in renal impairment.
Terminal elimination half-life is 16-18 hours in patients with normal renal function. Prolonged to 20-36 hours in severe renal impairment; no significant change in hepatic impairment.
Primarily renal (40-70% unchanged) via glomerular filtration; significant biliary/fecal (20-30%) as unchanged drug and metabolites. Enterohepatic recirculation occurs.
Approximately 40% excreted unchanged in urine via glomerular filtration; 20-25% eliminated in feces via biliary secretion; remainder metabolized. Renal clearance is about 30 mL/min.
