SOLODYN vs TERRAMYCIN
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 aminoacyl-tRNA from binding to the A site.
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.
250-500 mg orally every 6 hours or 1-2 g intravenously every 12 hours. Maximum oral dose: 2 g/day.

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: 8-10 hours in normal renal function; prolonged to 20-40 hours in severe renal impairment (creatinine clearance <10 mL/min).
Primarily renal (40-70% unchanged) via glomerular filtration; significant biliary/fecal (20-30%) as unchanged drug and metabolites. Enterohepatic recirculation occurs.
Renal (primarily glomerular filtration, 20-60% unchanged in urine), biliary/fecal (10-30% via bile into feces).
