Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP), thereby increasing intestinal absorption and decreasing clearance of substrates; also inhibits CYP3A4 isoenzymes, reducing metabolism of CYP3A4 substrates.
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.
100 mg orally twice daily (12 hours apart) on an empty stomach (1 hour before or 2 hours after meals). Avoid milk, antacids, iron, calcium, magnesium, and zinc within 2 hours of administration.
250 mg orally three times daily for 7-14 days; for sinusitis: 500 mg three times daily.

Terminal elimination half-life is approximately 18-22 hours in patients with normal renal function; prolonged to 30-50 hours in moderate renal impairment (CrCl 30-50 mL/min).
Terminal elimination half-life: 12-15 hours in adults; prolonged in renal impairment (up to 30 hours).
Renal excretion of unchanged drug accounts for approximately 60% of the dose; fecal elimination via biliary secretion contributes about 30%; minor metabolism (<10%) produces inactive metabolites.
Renal excretion of unchanged drug and metabolites: ~70%; fecal/biliary: ~30%.
