ATRIDOX vs MECLAN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ATRIDOX (doxycycline hyclate) is a tetracycline antibiotic that inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing aminoacyl-tRNA from binding to the A site. It also exhibits anti-inflammatory effects by inhibiting matrix metalloproteinases (MMPs) and reducing cytokine production.
Meclizine is an antihistamine with central anticholinergic properties. It blocks histamine H1 receptors and exerts antiemetic effects via inhibition of the vestibular system and chemoreceptor trigger zone.
50 mg subgingival controlled-release insert applied by dental professional into periodontal pockets once every 3 months.
250 mg orally three times daily for 7-14 days; for sinusitis: 500 mg three times daily.

Terminal half-life 16-18 hours; prolonged to 24-48 hours in renal impairment, requiring dose adjustment.
Terminal elimination half-life: 12-15 hours in adults; prolonged in renal impairment (up to 30 hours).
Primarily renal (60-70% unchanged), biliary/fecal (10-15%) as active drug and metabolites; remainder metabolized.
Renal excretion of unchanged drug and metabolites: ~70%; fecal/biliary: ~30%.
