CONSENSI vs PREVACID NAPRAPAC 500 (COPACKAGED)
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Consensi is a fixed-dose combination of amlodipine, a dihydropyridine calcium channel blocker, and celecoxib, a nonsteroidal anti-inflammatory drug (NSAID) that selectively inhibits cyclooxygenase-2 (COX-2). Amlodipine inhibits calcium ion influx across cardiac and vascular smooth muscle cells, leading to vasodilation and reduced blood pressure. Celecoxib inhibits prostaglandin synthesis via COX-2, reducing inflammation and pain.
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.
Adults: 0.25 mg/kg intravenously over 1 hour every 2 weeks.
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 elimination half-life of 12-15 hours for parent drug and 18-24 hours for active metabolite, allowing once-daily dosing.
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).
Primarily renal (70-80% as unchanged drug and active metabolite desmethyl-consensi); biliary/fecal: 15-20%.
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).
