DEXLANSOPRAZOLE vs PREVACID NAPRAPAC 375 (COPACKAGED)
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Proton pump inhibitor that suppresses gastric acid secretion by specific inhibition of the (H+, K+)-ATPase enzyme system at the secretory surface of the gastric parietal cell.
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.
30 mg orally once daily for 4 weeks for healing of erosive esophagitis; maintenance therapy: 30 mg orally once daily for up to 6 months. For GERD: 30 mg orally once daily for 4 weeks.
One tablet (naproxen 375 mg / lansoprazole 15 mg) orally twice daily.

Clinical Note
moderateDexlansoprazole + Clodronic acid
"The therapeutic efficacy of Clodronic acid can be decreased when used in combination with Dexlansoprazole."
Clinical Note
moderateDexlansoprazole + Alendronic acid
"The therapeutic efficacy of Alendronic acid can be decreased when used in combination with Dexlansoprazole."
Clinical Note
moderateDexlansoprazole + Technetium Tc-99m medronate
"The therapeutic efficacy of Technetium Tc-99m medronate can be decreased when used in combination with Dexlansoprazole."
Clinical Note
moderate1-2 hours; clinical context: duration of acid suppression exceeds half-life due to binding to proton pumps
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: 0% unchanged; metabolites eliminated via urine (51%) and feces (48%)
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%).
