Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Tetracycline antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing aminoacyl-tRNA from attaching to the A site.
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 PO q6h or 500 mg to 1 g IV q6h; maximum 4 g/day
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.

Terminal elimination half-life is 6-8 hours in patients with normal renal function. Half-life is significantly prolonged (up to 80 hours) in anuria, requiring dose adjustment.
Terminal elimination half-life: 11-22 hours (mean ~16 hours). Clinically, steady-state reached in 3-4 days; half-life prolonged in renal impairment.
Primarily renal excretion of unchanged drug via glomerular filtration; 80-90% recovered in urine within 24 hours. Biliary/fecal excretion accounts for <5%.
Primarily renal (40-70% unchanged) via glomerular filtration; significant biliary/fecal (20-30%) as unchanged drug and metabolites. Enterohepatic recirculation occurs.
