DOXYCHEL vs VIBRA-TABS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Doxycycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing aminoacyl-tRNA from binding to the mRNA-ribosome complex.
Tetracycline antibiotic; inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing aminoacyl-tRNA from binding to the mRNA-ribosome complex.
100 mg orally or intravenously every 12 hours on day 1, then 100 mg once daily. For severe infections, continue 100 mg every 12 hours.

12-22 hours (mean ~16 hours); prolonged in severe hepatic impairment (up to 30 hours).
Terminal elimination half-life: 18-22 hours (single dose); increases to 24-48 hours in renal impairment. Mean half-life after multiple doses: 14-16 hours.
Renal (20-30%), biliary/fecal (40-60%), with significant enterohepatic circulation; nonrenal elimination accounts for about 70%.
Renal (40% as unchanged drug via glomerular filtration), biliary/fecal (20-30%, including enterohepatic circulation).
