ACTISITE vs DOXYCYCLINE
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 binding to the A site.
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.
Topical application of tetracycline hydrochloride 10 mg/g periodontal fiber. Inserted into periodontal pocket and left in place for 10 days.
100 mg orally or intravenously every 12 hours on day 1, then 100 mg every 12 hours or 50 mg every 6 hours.

Clinical Note
moderatePaclitaxel + Doxycycline
"The metabolism of Doxycycline can be decreased when combined with Paclitaxel."
Clinical Note
moderateDocetaxel + Doxycycline
Not applicable due to local degradation; systemic half-life is negligible as tetracycline hydrochloride is not absorbed.
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.
Primarily eliminated by phagocytic degradation at the application site; minimal systemic absorption, negligible renal or biliary excretion.
Renal (40%) and fecal/biliary (60%); undergoes enterohepatic circulation; active drug and metabolites excreted in urine and feces.
