MECLAN vs VIBRA-TABS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Tetracycline antibiotic; inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit, preventing aminoacyl-tRNA from binding to the mRNA-ribosome complex.
250 mg orally three times daily for 7-14 days; for sinusitis: 500 mg three times daily.
100 mg orally twice daily on day 1, then 100 mg orally once daily

Terminal elimination half-life: 12-15 hours in adults; prolonged in renal 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 excretion of unchanged drug and metabolites: ~70%; fecal/biliary: ~30%.
Renal (40% as unchanged drug via glomerular filtration), biliary/fecal (20-30%, including enterohepatic circulation).
