DOXYCYCLINE vs TETRAMED
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 the attachment of aminoacyl-tRNA to the mRNA-ribosome complex. It also exhibits anti-inflammatory and anti-collagenase activities.
Tetracycline inhibits protein synthesis by binding to the 30S ribosomal subunit, preventing aminoacyl-tRNA from binding to the ribosome.

Terminal elimination half-life is 18–24 hours in patients with normal renal function; prolonged to 20–30 hours in renal impairment; allows once or twice daily dosing.

"The metabolism of Doxycycline can be decreased when combined with Cyclophosphamide."
Clinical Note
moderatePaclitaxel + Doxycycline
"The metabolism of Doxycycline can be decreased when combined with Paclitaxel."

Terminal elimination half-life is 12–15 hours in adults with normal renal function; in renal impairment (CrCl <30 mL/min), half-life may extend to >30 hours, requiring dose adjustment.
Renal (40%) and fecal/biliary (60%); undergoes enterohepatic circulation; active drug and metabolites excreted in urine and feces.
Renal excretion of unchanged drug accounts for approximately 60% of elimination; biliary/fecal excretion accounts for 30%; minor metabolic clearance accounts for 10%.
