FLUXID vs PREVACID NAPRAPAC 500 (COPACKAGED)
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
FLUXID is a selective serotonin reuptake inhibitor (SSRI) that potentiates serotonergic activity by blocking the reuptake of serotonin at the presynaptic neuronal membrane, increasing serotonin availability in the synaptic cleft.
Lansoprazole inhibits gastric acid secretion by irreversibly binding to the H+/K+ ATPase (proton pump) in gastric parietal cells. Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis.
1-2 g IV every 8 hours; maximum 6 g/day.
One tablet of naproxen 500 mg and one capsule of lansoprazole 15 mg taken together orally once daily. Naproxen component: 500 mg orally twice daily. Lansoprazole component: 15 mg orally once daily.

Terminal half-life: 12 hours (range 10–14 hours). In renal impairment (CrCl <30 mL/min), half-life prolonged to 24–36 hours; dose adjustment required.
Naproxen: 12–17 hours (mean ~14 h), prolonged with renal impairment. Esomeprazole: 1–1.5 hours (increase to 2–3 h with CYP2C19 poor metabolizers or hepatic impairment).
Renal: 70% unchanged; Fecal: 20%; Biliary: 10%.
Naproxen: 95% renal (primarily as unchanged drug and metabolites, including 6-O-desmethyl naproxen), <5% biliary/fecal. Esomeprazole: 80% renal (as metabolites, primarily hydroxyesomeprazole and desmethyl-esomeprazole, with ~1% unchanged), 20% fecal (via bile).
