EZALLOR SPRINKLE vs PREVACID NAPRAPAC 375 (COPACKAGED)
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
EZALLOR SPRINKLE (rosuvastatin) is a competitive inhibitor of HMG-CoA reductase, the rate-limiting enzyme in cholesterol biosynthesis. It increases hepatic LDL receptor expression, enhancing LDL clearance from plasma and reducing VLDL synthesis.
Lansoprazole, a proton pump inhibitor, suppresses gastric acid secretion by inhibiting the gastric H+/K+-ATPase at the secretory surface of the gastric parietal cell. Naproxen, a nonsteroidal anti-inflammatory drug, inhibits cyclooxygenase (COX-1 and COX-2) reducing prostaglandin synthesis, which mediates inflammation, pain, and fever.
40 mg orally once daily at bedtime; initial dose may be 20 mg. Dose range: 20-80 mg orally once daily.
One tablet (naproxen 375 mg / lansoprazole 15 mg) orally twice daily.

Terminal elimination half-life is approximately 19 hours (range 13-20 hours) in healthy volunteers; half-life is prolonged in patients with hepatic impairment and severe renal impairment, necessitating dose adjustments.
Naproxen: 12-17 hours (mean 14 hours); allows twice-daily dosing. Lansoprazole: 1.5-2 hours (fast metabolizers) to 3-4 hours (slow metabolizers); clinically negligible due to irreversibly binding to proton pumps.
Renal excretion accounts for approximately 88% of the administered dose (56% as unchanged rosuvastatin and 32% as metabolites); fecal excretion accounts for approximately 12%.
Naproxen: Approximately 95% excreted in urine as unchanged naproxen (10%) and metabolites (~60% 6-O-desmethylnaproxen and conjugates); <5% in feces. Lansoprazole: Primarily metabolized in liver; metabolites excreted in urine (14-23%) and feces (~22%).
